Title: Learners Project - Simple Grinding Rest
Post by: Joco on May 07, 2017, 02:38:51 AM
Next little project that should result in a nice usable tool and progress general machining experience.

So the game plan is take these blanks (pic 1) and turn them into this simple grinder rest as designed by Harold Hall (http://www.homews.co.uk/page146.html)

http://www.homews.co.uk/LrgGrindRestSim01.jpg

As you can see from the blanks I have lots of cleaning up and shaping to do.  The massive angle iron will get cut down to a circa 40x40 size with the cut-offs going into the steel collection bin for use at a later date.
I also have yet to cut off the round bar blanks but will get that done once I get some progress on rectangular parts.

Anyway, hope this little build and the resulting tool will be of interest to some people. The plans are in Harold's book "Tool and Cutter Sharpening" which is #38 of the "Workshop Practices Series" if you are interested in dimensions etc.

Cheers,
James.

Hi James,
That will be a great project!  I built Harold's advanced grinding rest from the same book.  Not sure it was a lot more difficult - if I remember right, the 'advanced' one has dovetails and the 'simple' one has a ball mount.  Maybe other differences too.  Regardless, it will be a fun project and as mentioned, a very useful tool.  I use mine all the time!

I'll be following along!  :popcorn:

Hi Kim.  The advanced rest was tempting but a little more than I really need.  The simple one does indeed use a ball mount to manage the front/back and side/side tilt of the table.  There is still one set of dovetails to make so not completely off the hook on that front.

Cheers,
J.

So to help me visualise how all the parts fit together and to allow me to convert some measurements to accomodate some slightly larger stock than the book plans suggest I have been modelling this in Fusion 360.  This also forces me to learn Fusion 360 as I see it as a useful tool for later CNC'ing of the Mill.  Since it can do both the CAD and the CAM parts of the process.  Anyway I digress.

This render gives a good view of how some of the parts below the table will fit together. The various screws etc are missing for clarity.

James,

While the ball is obvious, how do you plan to make the sockets? This will be a nice project to watch come to life. Do you also make accessory tool holders to work with this?

Alan
Title: Re: Learners Project - Simple Grinding Rest
Post by: Joco on May 09, 2017, 09:00:52 PM
Alan - re the sockets which I presume you mean the indents that the ball sits in and is griped by.   While making them as curved scoops would be ideal its not actually necessary.   They are really just over sized counter sinks.  The angle is more like 105 degrees not 90.  The easiest way to achieve should be to setup in the 4-jaw or face plate, set the top-slide to the correct angle and feed in.

On the accessories front Harold's book shows a range of accessories for it.   His website page http://www.homews.co.uk/page146.html (http://www.homews.co.uk/page146.html) also depicts them in completed form.  I linked to his photo below for convenience.

Cheers,
J.

Started some chip creation tonight but nothing interesting.  Just taking some of the raw stock and sanding off mill scale and squaring things up.   So no photos as thats kind of boring stuff.

Game plan is once evil work is over this week I'll get setup for photos, get out the layout dye and starting marking out parts, drilling some holes, making a slot or two and getting the kit to do the angles for the dovetails.

Right - the start of a mostly sunny looking if cool Sunday down under in NZ.  Chips shall be made and the temptation to practice with my TIG welder will be ignored (repeat after me .... "it WILL be ignored").

So today will be trying to get as much metal shaped, drilled and countersunk as my slightly fried brain can achieve. renders of the rests top assembly (still missing a couple of bits) attached.   I'm quite looking forward to this tool being usable, its going to make shaping some HSS lathe tools I want to make much easier.

Making chips!!  Mill getting nice and messy.

Getting everything to size is proving to be a bit of a mission.  I'm probably being way to soft on my kit and not taking as big a bites in a pass as I could.  Slowly getting more comfortable with the BF20's abilities and taking deeper cuts.  But eating up a bit of learning time in the process.

That's the way of it with these early projects - you just take your time and learn how your machine sounds and feels when its doin' it's thing.  You'll get faster as you know your equipment better, and get a better feel for how the different metals respond.  But it still takes time.  For me, that is one of the things I enjoy - slowing down and taking the time to do things carefully and well.  Not that I always succeed mind you, but when I don't, I learn. And hopefully, I always have fun while I'm at it!

So the working week has started so just small steps over the next few days.  Got a couple of parts done tonight.  The two parts that form the vertical adjustment have been milled.  There is one lathe operation left to do but until I get the plastic ball delivered then no mad rush to do that.

Pic 1 & 2:
Chain drilling before finishing the slot with a 6mm carbide 4 flute end mill.

Today was spent largely on another project needed to tidy up the mess of metal in the garage.  However after lots of TIG welding and a nearly equal amount of  :Mad:  :cussing:  :rant:   :wallbang:  :cussing:  :Mad: I hung up the TIG torch and played with the mill.

The result being I managed to get a couple more parts progressed.  The metal family is growing ... per pic #1.

The end of weekend wrap-up ...
I was all gungho to do the dovetails thinking I could use an angle plate set in my vice at the correct milling angle then clamping the parts to this against a fence for reference.  The fence idea being that I could get one part all correctly aligned, clamp some steel as a fence on its base so I could mount the other parts for dovetailing in the same spot.

Anyway, it all came apart when I discovered the angle plate will not fit my vice.  Its 12mm to big.  So looks like I need to get a smaller one or come up with another method for accurately and repeatably mounting this stuff.

However no to be completely daunted I went on to do some other needed operations, some that needed to be done before putting angles on things.   So ... drilled and tapped some M5 holes and set up one of the risers that will clamp the 25mm plastic ball on the lathe faceplate (first time ever using this) and got the 30 degree chamber needed to clamp on the ball.

The pics ...

#1: Setting up the part and using a 6mm drill to help align the 6mm hole.  It wasn't perfect but for what it will be used for it should be fine.  Clamped this as best I could and given its not the most beautiful clamping job set about running at slow speeds (200rpm) and stopping between each cut to check everything was holding.

#2: The result.  While not the most polished lathe work it should do the job and to be honest a less than mirror finish on this clamping surface is probably a good thing.

#3: The M5 holes in all their glory.  These were drilled then power tapped on the mill at the slowest speed I have (60rpm).  Got to love gun taps.

#4: A little bit of a repeat but a nice closeup of the riser arm with the big 30 deg chamber at the top.

Cheers,
James.

A two part update to deal with the limit of 8 pics per post.

First off was setting up an angle plate with a reference fence to allow for the two outer dovetail blocks to be created exactly the same.

Pic 1a:  Setting the angle.

Pic 1b:  A pic to give a clearer view of the little fence I made to allow repeat setting of the blanks for the outside dovetail blocks.  I will also use the same setup with no movement for doing the inner dovetail block.

Title: Re: Learners Project - Simple Grinding Rest
Post by: Joco on May 28, 2017, 11:47:24 AM
Part 2.

Getting the first part all clamped up and ready for milling.   Since the angle plate is a little "in the air" I am taking small nibbles from the top using a 10mm carbide end-mill at 0.3mm per cut to get rid of about 5mm then a final 0.1mm finishing pass to get to size.

So ... the pics    :popcorn:

Pic 2 & 3:
Showing the clamp up using my toolmaker clamps.  These are starting to prove to be very useful little items.  I am going to need to make some more of these.

Pic 5 (pic 4 removed as redundant):
The cutting in flight, a nice little pile of swarf appearing.

Pic 6:
The cut all finished in the clamp setup.

Pic 7:
The two outer dovetail blocks finished up.

Pic 8:
The two parts "nose to nose"  and looking nice an symmetrical.  But just how good was the setup for repeatability?

Pic 9:
The two parts on a flat surface with 60 degree faces matched up to see how tight a fit they are ... don't know about you but these look pretty dang good  for something straight off a mill to me.

The final part of the dovetails components is the sliding center piece.  This part will have the plastic ball attached which will form the main pivot point for the rest.
On the whole the fit between the parts is pretty close and things slide very smoothly.  Which is important as the recommendation is to NOT lubricate the dovetails due to all the grinding dust they is going to be about.

Pics attached.

A small update since the garage is freezing tonight.

Completed the slot on the table top.  Pretty standard process of marking out the ends of the slot, chain drilling the slot then finishing it with a 6mm carbide end mill.

The picture shows the slot and the the dovetail parts placed in position on the underside of the grinding rest top.

Title: Re: Learners Project - Simple Grinding Rest
Post by: Joco on June 03, 2017, 07:49:09 AM
Some progress today with getting the dovetail blocks mounted on the underside of the rests top. The rest top is 6mm mild steel nominal value, actual size being 5.9mm after cleaning off the mill scale.  The M3 threaded holes are drilled 5.3mm deep and then threaded using a bottom tap.  The challenge here (per Harold's build instructions) is to get good thread engagement with the bottom tap from the start so as to maximise the amount of usable thread.  With the shape of the tap it looks like effective thread depth is about 4.5mm to 4.8mm.

So to solve this problem make a simple tapping jig that contains an M3 tapped hole which the M3 tap goes through.  Clamp it to the work and use the fact that the M3 tap will fed down into the hole at the correct rate to ensure a positive threading start from the beginning.

So now for the pics, cose we all want pics right?     :popcorn:

Pic #1:
Shows the tapping jig and the Irwin tapping attachment I used to get a grip on the tap.  Given how thin the M3 tap is this is just turned by hand with no handle and that gives a really good feed for how much tension is on the wee tap.
In the background is the first stage of the process I am describing done with the back M3 screws in place.

Pic #2:
After referencing off the actual hole in the dovetail block the resulting hole drilled to 5.3mm depth and ready for tapping.

Pic #3 & 4:
The tapping jig mounted and ready to start.  You can see the nose of one toolmakers clamp used to hold things.  Really starting to love these wee clamps.  So useful.

Pic #5:
Moving on to the final hole and tapping operation pretty much done.  You can see the tapping oil around the hole.   The general approach was a drop of oil into the hole before putting the jig in place and some oil on the actual tap itself.

Pic #6:
The final product.  Dovetail blocks all mounted up and a nice clean sliding movement from the central block with the M6 screw protruding from it.

Cheers,
James.

A little more progress, a lot of learning and fixing some alignment issues on the lathe.

Today was doing the other half of the ball clamping system and after liking the result cleaning up the original clamping part to be a better finish.  I also started some of the threaded rods that adjust things. Learning to turn such small diameters (6mm turned down to 5mm) was ultimately successful but the threading using my Frost dies was a failure as the first 5mm just got chewed up until the rubbish dies started to bite properly.

I also discovered quite a bad taper was being turned on the lathe.  Some checks showed things were not very flat.  Out by between 0.3 to 0.6 degrees in left-to-right and front-to-back respectively.  This was resulting in a taper of over 0.1mm across a very short distance.   Some adjustments with the digital level and I got the taper down to 0.01mm.  The only way I will get things better is to start using some shims between the lathe and the bench top. I'm quite keen to try and get this as good as I can so time to get some aluminium drink cans and start making some shims.

Anyway on to the pics.   :popcorn:

Pic 1:
Shows the underside with the plastic ball mounted and the (to be replaced) threaded rods in place.  If nothing else it has acted as a proof on their function and I know exactly how to go about making them for the next crack.

Pic 2:
Shows the setup for the final ball clamping part.  I figure out a way to get it clamped and not move about plus using the boring bar gave me the reach I needed to avoid bolt heads.

Pic 3:
The original clamping part in place and cleaned up using this clamping style. You can see a few slimmer clamps that are the beginnings of a low profile clamping set.  There is also a lone mill-clamp on the edge which was needed to balance out the weight on the face plate.

Pic 4:
The two clamping parts and the dovetail with plastic ball mounted.

Pic 5:
Simple "dry" assembly to show how things will get clamped.  Still need to make the spacer that will go at the base of the shorter clamp.

I managed to borrow an nice HSS M5 button die from Bruce and decided to redo the last two threaded rods which had the nasty stripping of the  thread on the first 5mm or so of the thread.

So here a series of pics of the first one I re did.

Pic #1:
Setup of the 6mm stock with support to be turned down to 5mm.

Pic #2:
Turned down and ready for threading.

Pic #3:
And a threading we will go.

Pic #4:
And the results.   You can see the new part on the left.  Nice clean thread with a good start right from the beginning. The one of the right is the original and you can see how rubbish the first ~5mm is.  Stripped and just yuk.

Cheers,
James.

A short update of some of the fiddly bits.

Pic #1:
Shows the threaded rods with their retention sleeves in place.  These now need to secured properly in place.  A mix of loctite and a pin should see these being pretty solid.  Although I do have a half formed idea that a little TIG Brazing on the threaded side will hold stuff in place forever.  But we shall see I'm probably at risk of over engineering things again.  :facepalm:
You can also see the locking rod with its little brass cap.  That was a pain to make.  Its 4mm wide with a 2.4mm shaft that inserts into the rod.  The other rounds are the beginnings of the knobs that will go on the ends of these shafts.

pic #2:
This is a close up of the locking shaft with the brass insert installed.

Cheers,
James.
Title: Re: Learners Project - Simple Grinding Rest
Post by: Joco on June 10, 2017, 01:32:08 PM
Okay I just couldn't stop. The knob blanks were sitting there in a very accusatory way.  "Machine me ... machine ME ... MACHINE ME DAMMIT!!!"

Pic #1:
This is the setup used to machine the knobs.  The toolmaker clamp provides a stop so I can turn the ER32 Hex block and reposition in exactly the same spot. The mill tool is an 8mm bull nose HSS bit. The knob blanks are 1215 engineering steel, 19.90mm round.

Pic #2:
The knobs all done other than the set screw holes.  Things were getting a bit dang cold in the garage so that can be a tomorrow job. You might notice that the indents don't go all the way down the sides. There is a 3mm band still left intact, The idea is that at some point I will have the setup to put marks on the knobs.  Given the threads is M5 x 0.8mm which means if I put 40 divisions on this I get 0.02mm travel per division.

Pic #3:
"Dry" fit up of the knobs with the various shafts. Starting to look more and more real.   :ThumbsUp:

Managed to get some nice progress on the transport block that the fence will be mounted on and which will allow small adjustments of the fence position. Todays achievement was to get the blocked drilled and tapped to run on the M5 lead screw.
General process was:
[1] to get the block mounted in the mill vice vertically then aligned for drilling
[2] drill with 11/64 all the way through (total hole depth is 45mm)
[3] drill 25mm at 4.5mm to a depth of 25mm
[4] ream to 5mm to 25mm depth
[5] tap M5 all the way through on the remaining 11/64 sized hole using a tap wrench

The setup was not changed through the entire operation to ensure no alignment issues.

A nice evening distressing in the garage.  Decided to stop once it got to the point each breath was a puff of steam.   :Lol:

Pic #1:
The holes drilled, tapped M3 and the everything mounted up properly.

Pic #2:
The top of the table.  You can see the transport block pocking through the slot.  It now needs to have the fence mounting holes drilled and tapped.

Pic #3:
This shows how much the transport block is sticking through. This is intentional.  I need to blue the sides and run a scrip along the sides flush with the top of the table.  I can then mill down to that line and have the block nicely flush and ready for the fence to be mounted.

Bit of an update from the last few days of making chips.

Basically we have the fence transport completed having the mounting holes for the fence drilled and tapped.
The full assembly of the grinding rest.
The completion of the fence other than the needed M5 screw to mount it to fence transport that I had forgotten to order but are now on their way.
The locking thumb screw on the fence that I made today.  Just turned down from 10mm round then grips made with a 4mm end mill.

Pics 1 to 4: The grinding rest assembled. Still in need of a cleaning bath to get all the blue off.  But that will happen soon enough.

Pic 5: The basic blank for the fence.  You can see the M3 screw on the side at the front which acts as a stop.

Pic 6: The fence cleaned up and the locking thumb screw in place.

Pc 7: Close up of the thumb screw to try and show off the milled grips.  Could probably do with a final cleaning facing pass to really clean up the top.  But its perfectly functional and smooth as is.

Cheers,
James.

These are mockup pics of the grinding station.  The base is 16mm thick melamine board cut to 600x600mm and a sandwich of two sheets glued together.  The grinder is raised up by 18mm to get a better position for the rest and to allow more options on the vertical adjustment.  Next will be to finalise the position, market for holes  and the threaded inserts.

Hi James,
I don't know if its just me, but your pictures didn't show up for me in this post.  They're just little broken link JPG icons.

Can others see the pictures?

Ah well, may just be me.

The pics in post #44 are linked from google drive as public shared links.   I'm trying out doing this using a something other than attaching pics to the forum.

Things seem to work fine in Safari.   I can replicate the issue of the pictures not appearing on Firefox in Win10 and OSX.  So will look into this some more.

edit:  Tried a slight variation in how I get the link to the photo.  Let me know if its starting to behave or not.

Cheers,
J.

Yup, I can see them now, and your grinding rest looks great, James!  :ThumbsUp:  :ThumbsUp:

Well its all drilled and bolted to the top now.   It basically looks the same as the dry fitting pics I have already posted so I won't do another pic as the delta is just some bolts into wood.

So this is it.  Done.  I hope its been of a little interest for a few people.

I have some of the accessories to do next. various holders for square and round stock, the end mill sharpener and anything else that I end up determining is needed.   As I complete those holders over the coming months I'll post a pic of them.

Cheers,
James.

I'm sure that you will use this again and again over the years - so it has been a good investment of time (and money)  :ThumbsUp:

I really liked your last pictures, where you can see how many "problems" you solve with it  :praise2:
