6x4 Bandsaw Cart - project looking for a problem
« on: March 24, 2017, 10:00:55 PM »
Killing some time while waiting for metal to cut ...

I have a problem, no space to get wifes car back in the garage so I need a solution ... best form of solution, a PROJECT!   :naughty:

So I have all this box section steel tube and a 6x4 bandsaw screaming out for some unwanted attention.  Put them together and you get a project looking for a problem ... errr I mean a solution, yes a SOLUTION god dammit!   :noidea:

So obviously we design up a new cart for the bandsaw to use up said steel, one with wheels, a drip pan, the possibility of coolant, some storage, room for twin motors, 3 phase power ... power ... more power ... MORE POWER.   :mischief:

Oh - I hear metal falling and hitting concrete.  Time to feed the cutting machine again.

Pics and more slightly crazed commentary to follow.

Cheers,
J.

Rudy Kouhoupt did a cart for that saw....I did my own version....

It doesn't need to be steel, but if you have the hankering for it....have fun!

I'm looking at incorporating my saw into my mobile bench base.....we'll see.

Hi James,
 I just put a bunch of ideas from other people together in one place with some changes I thought about while on night shift......about the only advantage of working 12 hours on your own, plenty of time to think of things!
Sounds like I better brush up on my drafting skills!

I will dig out the plans tonight but got the top and bottom frame welded up. Its not had the joins ground dowb yet.  I took my time on these and really thought about heat management and how the welds would pull.  The result is some really straight frames.

Construction is simple: big frame on bottom, smaller on top. Lower frame overhang will be under the motor when saw is in the vertical.  This should give stability.  Drip tray will be on inside of top frame. Ill put a shelf on the bottom frame to hold stuff.  Also top frame will have supports for extending work piece support to the right of the blade.

Cheers ,
J.

Its been and continues to be a rathe distracting week with little shop time.  I did manage to layout the frames and uprights to show the basic shape coming together.

Hopefully the weekend will be kinder and some real progress will be made.

Frame all welded up. Sunday will be adding the wheels and the cross supports that the saw will actually mount on.
Also plan to break out the plasma cutter and cut up some 2mm sheet steel to make the drip tray and a lower shelf.  Then it will be painting painting painting.

Oh well, the best laid plans of mice and men.   :old:

Got some stuff done today but not as much as I had hoped.  So the wins of the day being.

[1] Got the 40AMP plasma cutter unit all plumbed up to the compressor with double moisture traps on the line as I have heard that any moisture line the air will cause the torch to burn through tips rapidly.
Then use said cutter for my very first use of a plasma cutter - ever.

[2] Bandsaw cart progress.
Pics #1 to #3 show my first attempt at cutting stuff.  The slag on the back of the cut breaks off very easily with a cold chisel just being used by hand, no hammer.  The cut was done with a straight edge but I had issues with torch height.  I think I need to make some kind of support on the torch head that will keep the tip at a constant height and square to the metal. The same support could also be attached to a trammel system for cutting arcs/circles.

Pic #4:
The wheel mounting pads (6mm mild steel) which were initially hacked off with the plasma cutter then halved on bandsaw for a little more accuracy. Pads all welded on and ready to be drilled and tapped M6.

Pic #5:
Two wheels mounted.  I got one more mounted then I gave up for then evening.  After breaking a 3mm drill and a 3.5 mm drill I decided I was getting too tired.

Pic #6:
Close up of a mounted wheel with the M6 screws holding it all on.

A little more done today in between some family time.

Got the last of the wheels mounted.

Cut the mounting cross beams and the "tabs" that will be the bolt mount points.  Then laid them out on top of the cart.
What I can't quite decide on is if to have the bolting tabs on the outside of the saw body or on the inside.  See pic #2

Anyone think one is better than the other?  Ascetically I suspect the inside option would look cleaner.

Cheers,
J.

Cheers Kerrin.  I'll do that.   Also been pondering how to mount a tray and keep enough clearance from cables and such.  I don't want to raise the cross beams up as that will make the saw rather high.   I think I have a plan that will use up some lonesome 25x2mm angle iron.

More pics post welding fun tomorrow.

Hi James,
 The tray I used I picked up in the kitchen ware section of the red shed when R was looking for something, the lite went on when she picked one up! I had a bit of 15 mm Ali channel, drilled a couple of hole in the tin legs. I guess you are going to use the angle on the main frame, between the saw supports?

The top frame is a 700 x 400mm rectangle. Taking out the SHS size of 35mm still leaves a big "tray" area.  Unless I reduce it to only being between cross support beams.

Part of my thinking had been to have the whole area inside the top frame as a tray so I could easily add pumped coolant.  The large trap area would mean no risk of drips traveling outside of the catchment area.   Perhaps I'm over doing it?

I have that angle iron plus I have a sizeable amount of 2mm sheet to make the tray bottom to sit in the "L" of the angle iron.

Cheers,
J.

This is the type of concept I'm aiming for re the top tray.  Full width and length coverage to capture all metal shavings and any form of coolant/lubricant system used.

Continuing on with my theme of "just a little bit more" I've managed to make some progress in between other garage committments and my son wanting to make Woverine claws on the 3dprinter for a short film hes's doing with mates.

Got the cross supports setup and the saw off the old stand.  Things are all welded up now and ready for the next stage, putting the bolt tabs on.  Note: this pic was pre welding but other than some welds nothing really different.

Last update for the weekend.  Started welding the tabs that will sit inside the bandsaw's casting.  They need to be at an 82 degree angle so a little bit of trig showed I need about a 5mm riser to get the required angle.

I don't have any welding skills but I do have one of these saws which has served me well so far but the modifications look like something that I will be considering in the future.
I do not have 3phase where I am in the country just 220 voltage which is the regular set up for residential. mostly just 110v motors. The whole hydraulic adjust-ability set up is definitely first on the list,   yes the spring adjustment is practically useless.

Mike - I think the 3 phase motor and VFD is a little OTT for a hobby grade saw.  I do agree that the hydralic down feed would be a great upgrade over the spring.  Sourcing a suitable cylinder that isnt nearly a quarter the price of the saw is proving to be a challenge.  Up to the point I am seriously wondering if its viable to make one.  Could be an inerersting little project   :noidea:

Hi James,
 making steady progress...

here ya go for your hydraulic cylinder!     http://mikesworkshop.weebly.com/bandsaw-hydraulic-cylinder.html

Theres plenty of options on Google....but like you say finding a cylinder down under that doesn't use up a years worth of moths...errrr workshop budget is a mission. The one above uses a length of tube.

Kerrin - that's an awesome link and should be a fun little project to make the cylinder.   Fortunately I've been a member of that yahoo group for a while to found the drawings that are ultimately referred to reasonably quickly once I went looking in the files section.

Some more good progress with the switch being remounted and a new fitting to "knock" the off button in its new position.

The base fits nicely on the finalised mounting tabs (set on the inside of the casting base) with the bolts nuts welded on to to angled tabs.

Now to start working on the cut off support table.

Some more progress.   Key steps forward being:
[1] Frame painted up (pic #1 & 2)
[2] drip tray secured in place with drain plug installed to support coolant system (pic #1 & 2)
[3] new mounts for switch and the cut depth stop (pic #3)
[4] version 1 of a cutoff "table" built and installed (pic 4 & 5)

Kerrin - have a look at a previous posts pics. If you use the 12mm round bar that the length stop is mounted on that comes with most of these saws you should see how I have gone about it.  Not that my approach is original at all.

One learning is that I welded my mounting blocks and the beads have pulled the ends of the table down a bit so its not as flat as I would like.  Okay for a starting position but not as good as I finally want it to be.  I didn't think the 6mm steel would pull like that.  Oh well, all about learning.

Also watch out for how parallel the bar is to the saws cutting surface. From what I have read its never parallel and mine certainly wasn't.  Out but a couple of mm between the ends.

Cheers,
J.

A little bit of a mixed update on the bandsaw cart.

[Pic #1]
Just a little show of utilising some clamps and the toolmakers clamps in a way to get around clamping limitations of the saw vice.  At least until I can get some stock cut to make jaw extensions and the separation rod to keep the clamping jaw from pivoting.

[Pic #2]
I embarked on a bit of work with the brown stuff today getting some shelf boards made.  This is the one for the cart bottom and I also did one on the lathe stand while I was on a roll and managed to neatly use up the last of a sheet of plywood. This base will ultimately have some draws and cupboards added to provide a little more storage space and to keep all the bits relating to the bandsaw in one location.

[Pic #3]
This is the delivery end of the bandsaw coolant.  The steel block (I would have preferred Aluminium but I just do not have the stock) will be the basis for the mounting block for the flexi spout and for a hose barb to be screwed into.  I'll have to model this idea up and will try and remember to post the render/plans for what I come up with.

Trying to keep multiple projects going at the moment but thought this use of the cut-off table might be of interest.

Essentially I needed to cut some 60 degree angles and I didn't want to muck up the main fence which I have nicely set to an accurate 90 degrees to the blade.  Using a protractor to clamp a fence I was able to hold the steel sections securely and reputably at 60 deg to the blade.  Worked pretty well for the 8 parts that I needed to cut.

Hi James,
 Now I know I have to figure out how to put the table out the side...nicework! Probably an easy yet another add on, just remove the adjustable end stop & slide the table on should do it.
On the main fence....get your drill out drill through the fence & through the table fit a pin, then no problem getting it square.

Oh BTW I've done drawings for my table mods so if you would like a copy just ask, goes for anybody else as well.

Cheers Kerrin.  The cut off support table is proving to be quite useful.  Has me thinking about something larger and more permanent.  At the moment as I still have 12 months of warranty on the saw I'm avoiding drilling any new holes in it.  Later though ... well it's all on.  Pins for key reference angles, larger and properly affixed cutoff table are on the list.

Re your plans - would love a set of drawings.   Maybe post them against your original mod thread?

J.

Hi James,
 Yes probably not a good idea to give the supplier any more reasons to not pay out! :lolb:

Was going to put against the original post....just got to convert to PDF & add some words as to what may need looking at to fit a different saw.

Had fun doing the drawings...had to talk to son in Canada on how to do some bits of it! Hopefully what I've done other can follow! Brain R will probably need up on the floor  :lolb: !!

Another small change which was suggested to me by bruedney.

Such a simple thing and its like I have a new saw.  What is this change you might ask? A new M20 classic V belt (https://www.bayengineerssupplies.co.nz/products/power-transmission/belts-pulleys/m20).  I still had the original Chinese supplied belt. Looked ok, but in all honesty I wouldn't know a good belt from a bad one.  Anyway bruedney suggested a new belt might be a good idea, I sourced one from a local supplier (actually from Tauranga: https://www.bayengineerssupplies.co.nz) for a mere $3.40 (plus GST and $8 shipping so I got a whole bunch of screws to make it all worth while).  Anyway previously I had really bad vibration, to the point I was wondering if the wheels the blade ran on where not very concentric.   However put this new belt on tonight and the saw is better than new. It's rock solid and much quieter.

WIN!   :whoohoo:

 8)

I had a similar experience with the blade on my startrite band saw: It came with a fine toothed blade (8 tpi ish) which cut like a dream, even aluminium, until it broke  :'( The second blade it came with was a 3 Tpi pitch and it vibrated all over the place :o and nothing would stop it vibrating, until it also broke  :-[.

I then brought some expensive replacements and fitted the first blade a 3 tpi AS (alternate set) blade.... Round it went tick, tick, tick  as the weld went through the guides  >:(..... Then after a few cuts I realised that it had stopped going tick, tick, tick and was as quiet as the original blade could focus on the fact that actually it cuts like a dream  ;D

I also brought some vari-pitch Starrett bi-metal blades for metal cutting that I have yet to try but based on how well that AS blade settled in and works I am very hopeful.

A small update on the cart. I plan to add another shelf to
[1] support the coolant reservoir "bucket"
[2] provide an area along the base of the cart under the shelf to hold cut-offs

The tabs for the shelf are off-cuts from another project and TIG welded into place.  That in itself was a big learning exercise.  Moving from TIG welding all nice and comfy on a stool at the table to on the floor trying to align to the torch at odd angles with minimal support and doing uphill welds for the first time.  Oh well, who wants to make it easy?    :naughty:

Bandsaw DIY coolant system - TICK

Not claiming much originalty in this as you can find a number of examples on the net.  However I thought I would share my attempt at a coolant system on these small hobby metal bandsaws.

Starting out with some hex brass stock thanks to Bruce for that material.  Drilling 6mm all the way through then enlarging to 11.5mm to a depth of around 20mm ready for the 1/2-20 tap.




All tapped and tested with the coolant pipe.


Next was to create the end for the coolant feeder pipe to go on.
Starting to turn it all down.
<a href="https://www.youtube.com/watch?v=2DC74XB3b80" target="_blank">http://www.youtube.com/watch?v=2DC74XB3b80</a>


Comparing my work to the plastic fetting that screws into the submerged pump.


Ready to TIG braze the brass parts together.  For the record brass hates me when it comes this process.  I have had no issue with steel to steel. But Brass to Brass or Brass to Steel has been a nightmare.


The results after MUCH cleaning. You can see the figghts I had getting the silicone bronze filler rod to "flow" and the trouble I had with over heating the base metal in an effort to smooth out the filler rod.  But in the end it seems to be stuck well enough for what I need.




Ta da!  The custom fitting on the bandsaw, adjustable nozzel in place plumbed up to the pump system.


Steeping back and looking at the saw in total.


Under the system I eneded up having the drain drip straight into the bucket.  I'm going to look at this some more and see if there are some improvements to be had.


Now for some live action ...

Hi James,
 Nice addition!
 Do you find the blade takes the coolant right round the blade or is your tray big enuff to catch it all? A guy local did this upgrade & gave up on it as he had coolant all over the floor!

Kerrin - my tray/stand is nearly large enough but there is a little dripping on the rear frame beam.
<a href="https://www.youtube.com/watch?v=ZfXmy8YSqxM" target="_blank">http://www.youtube.com/watch?v=ZfXmy8YSqxM</a>

I'm working through a simple drip trap which can be made from angle ali or steel that will solve that potential problem.  Bruce "bruedney" has a similar stand and solved his problem very elegantly with some spare copper pipe he had.

Once I have done my solution I'll show some pics.  Also some rubber/silicon wipers just before the blade enters the main housing would stop the vaste bulk of coolant going further than is desired.

I'm also tossing up whether I continue with the 240v submersible pump or swap it out with a 12v version. The 240v version is a fully sealed commercial unit on public sale but I guess there is always a degree of paranoia with mains voltage and water. Plus the 12v version I am looking at has a higher potential flow rate and the flow rate is adjustable.

Cheers,
James.

Hi James,
 Right sounds like you've got it sorted! Now I'll need to go look at mine & see if I fit one if I can catch the coolant on my tray as is......

On the pump front yeah I know what you mean 230 & water not a good mix! 12 much better! As to volume I guess that's a personnel choice, I guess somebody here will be able to tell us !

Cheers Kerrin

Thanks Kerrin.

I had another look at my plans for the rear drip catchment. I can already hear the cries of "over engineered!"

My coolant trap will be glorious!   It will support an adults weight and cope with 40 ltrs/min being flung about. It will also auto adjust based on drip rate, provide an audible alarm on over flow and make me coffee when I'm starting to fade.

Ah but you have a non standard mounting system that is incompatible with the hyper drip entrapment system.    :lolb:

Having designed up the idea for a rear catchment system to catch the errant drips here are some pics of the idea pre welding.  You will see a small welding magnet in the pics.  This is really just holding things in place with its weight since the parts are made from 50x50mm ali angle.

Got the parts welded and all cleaned up.   Plan for the weekend is to get things all mounted up.

Well it looks like it's conforming to most of the design brief!  :lolb:

12v bilge pump to replace the weak fountain pump is on the way.  This will improve the head pressure and make the pump less susceptible to clogging with crud.

It also reduces the voltage exposure to 12v compared to 240v.

I'm also looking at the possibility of a fabricated coolant tank that helps to separate any metal and tramp oil caught by the coolant.

It's started - I managed to get motivated to started the custom coolant tank.  Initial tacking up of part tonight.  More to follow this week.





Some of my initial cuts are not brilliant so I will need to do some trimming on the table saw before getting too far.

The coolant tank for the bandsaw continues ...

The weir welded in before other sides are put on.


Side panel in which the connection fitting will be welded.  This supports the tube connections between pump and the coolant line external to the tank.




Just showing my attempt at welding around the fitting.  Still getting more frosting from cleaning action than I think is supposed to happen.


Top view looking into the tanl with the pump in the position it will ultimately be installed in.


Bit of an overview of the tank to date.
<a href="https://www.youtube.com/watch?v=qzyB5bKHA6M" target="_blank">http://www.youtube.com/watch?v=qzyB5bKHA6M</a>

Next major activity is to fully weld all the seams up.

To supprt that process I needed a means to support my hand over a ~30cm welding seam at a really ticky height.  So taking inspiration from what I have seen on Welding Tips and Tricks I found some offcut 35mm square tubing, got some 20mm ID (27mm OD) galvanized pipe and a flange fitting from Bunnings and hacked this up. Key parts are:
- 1200mm length of 20mm galv pipe, cut that in half
- 20mm galv flange fitting, acts as the base
- off cut 35mm SHS
- M8 cap screws and nuts

Water leak testing underway ...



After a couple of hours still bone dry on all seams.

Taking the tank further with lid and the start of the piping, just to show things are still slowing moving forward while being interupted by work committments.
