Scroll saw attachment for a lathe

[steamer]

If you had the desire and need, but not the space for a good scroll saw...would you consider a scroll saw mounted to the tool post of your 9" +    lathe and driven by it?


..........GO!

:-)  Not having either the need or desire it's hard to say. :-)

Many years (decades!) ago, I had a setup like that on a small lathe. It worked well, but the vibration was an issue. Even on dedicated scroll saws, they tend to vibrate like crazy.

Interesting......

Stay tuned.....

..........GO!

Dave...........I haven't thought about a scroll saw, since I already have a nice one. But what I have thought about is a small filing machine driven off of my lathe. I think some of the same principles would apply so will be watching to see where this thread leads.

Jim

[gerritv]

Unimat had attachments to accomplish this.

It is certainly better than not having a scroll saw, useful for lots of things even metal  work.

And I do mean scroll saw....12" throat.

I have a small Russian lathe that was sold as 'Universal Machine Tool' which came scrollsaw attachment, 4"wood saw attachment (with guard) and grinding wheel. I have only used it as a lathe but might turn the scollsaw into a die filer setup. All up its a wonderful piece of accurate Russian machining.

I went over to Amazon to order one and it looks like they're "out of stock"!

[steamer]

yup.....Waltham stopped making that lathe in 1914.

I know.....I have one...

Dave

[DTR]

Perhaps not relevant here, but Millers Falls / Goodell Pratt / Hobbies offered a scroll saw attachment for their small wood lathes. They are still fairly common in the UK:

[90LX_Notch]

I believe there are a couple of people offering die filer casting kits.  Martin might be one and there is one in Pennsylvania that offers a bunch of stuff for South Bends.

Here's a video of a Martin Machine (http://www.martinmodel.com/MMPtools.html ) Die Filer being driven by a lathe: <a href="https://www.youtube.com/watch?v=anJowyNQcO0" target="_blank">http://www.youtube.com/watch?v=anJowyNQcO0</a>

Ah! I think I get it. I was really confused about a scroll saw and a lathe.
The video helps! I recall seeing a die-filer on a lathe.

Neat!

[Tennessee Whiskey]

Gee that looks familiar. I gave that one to my BIL for Christmas year before last. Now I need to build me one

That's the beauty of doing that way.   I have a variable speed motor and a nice heavy bench all ready....just add saw.

Screw it.....I'm doing it.

Dave, I don't know if your referring to building a die filer or a scroll saw, but if it's a die filer, here's a great thread that some guy (not sure who the heck he is  but he sure seems to know what he's doing) did a while back: http://www.modelenginemaker.com/index.php/topic,4963.0.html

[steamer]

Some pictures.   The arms are from the article by Heden in home shop machinist.   They are wooden and made from Masa anduba.     It's a tropical hardwood about the consistency of woodpecker lips.     

[steamer]

More pictures.  The tool post block is from a bunch I made for other attachments.

[steamer]

A few more

I'll need a bellows of some form...I'll sort that after it's running...

Dave

[steamer]

The wood is very stiff and hard, but lighter than aluminum.  Should help with the vibration...though I have about 450 pounds to help out with that.

The table will be a fixed 9" diameter x 1/4" thick aluminum.   I'll machine it for a zero clearance insert that I can swap out occasionally.

No tilt on this one, most of what I want to use if for is thin brass/aluminum and plywood under 1/4" thick.

Having said that, the table will be attached to the aluminum beam via 2 #10 screws.    Simple as can be.

Piercing blade with holders shown.   

Dave

[steamer]

Some progress made on this too.

[zeeprogrammer]

A bellows? Now I'm lost. What's that for?

[steamer]

A small bellows is usually attached to the arms so that as it cycles up and down, it puffs air at the cut zone and blows the saw dust away.

Dave

[steamer]

Wow!  nothing!    I would have expected more....oh well...

Ordered material for the table today.   Just needs facing and screw holes.

I'll get the crank sorted out this weekend.   I have a fixture I need to make for work.

Here's a proper video write up of a decent small scroll saw of similar size Zee..   It' explains the finer points

I'm following along Dave.  Don't need a scroll saw, but am anxious to see how you do the drive system, since it would work for a small filing machine the same way.

Hi Dave,
 Following along! Was going to post on your bellows but well you know....err better not said!

Got to thinking about it....over engineered but hay it's all about making something.

Use your compressed air, reduce the pressure way down, a small ball valve actuated by the arm to open & close, nozzle to the cutting front, adjust air pressure  to get desired puff...done!

Shouldn't take more than 5 mins as my old man used to say. Figured out that pretty quick if he started a 5 minute job at 9 in the morning, we might be finished by 5 in the arvo!

Cheers Kerrin

Hi Jim

It's just a simple crank with a connecting rod.   I should have something this weekend.

No compressed air in my shop Kerrin.     The other opportunity would be what I had planned already

[zeeprogrammer]

Thanks Dave.

I know what a scroll saw is...I'd just never seen one with a bellows. That's a neat way to blow the dust away.

[steamer]

A bellows "Dust blower" is standard on just about every scroll saw on the market. Even the old saws had them...

 Wish I had the space for an air compressor, or a scroll saw... or a hydraulic press...ect.

I don't

[Ian S C]

At our local museum there is a homemade scroll saw with a dust blower made from an old food tin about 2" diameter, and operated by the top arm of the saw.
"Forty Power Tools You Can Make" Popular Mechanics Press, my one is dated 1944, has two designs for scroll saws, both have blowers, you can probably find the articals on the Popular Mechanics web site.

[steamer]

Thanks Ian!   I'll check that out!

I'm putting this one under the heading of simplicity ...though you have to admit, it doesn't get any more simple than this    Read the caption on the last photo....genius!

[zeeprogrammer]

I hadn't seen a scroll saw for many years. Those I did were pretty simple affairs.
If they had a blower...I probably did not recognize it as such.
My image of a bellows doesn't match either.

I just googled around and was surprised. Pretty neat stuff.

More interesting to me was how you're putting your lathe to work.

I can hang this saw on a nail over the lathe and not take floor space.   Pretty key      Having a simple way to pierce small sheet work is also key.

Once I get my bandsaw off the floor and on my "Dirty cart" I'll free up enough room for a small work bench    Probably a clock makers bench     There is no where to sit in my shop.   Doing really small work while standing is very tiring on a concrete floor.   Even with a mat, it's hard.  I need to be able to sit comfortably, with good light.

I'm really enjoying this.
I've sometimes thought about a scroll saw but was hesitant to buy, find a place for it, and then barely use it.
Building one driven by the lathe is excellent. The filer is another one.
I mean, why wouldn't you?

Well, depends what you are going to use it for. My scroll saw gets used for woodwork, dont really want all that wood dust mixed in on the oily lathe. If used mainly for sheet metal and the like, sounds like a good way to go if it is easily put on/off the lathe.

[zeeprogrammer]

Actually reminds me of something I was told long long ago. I think I'd even asked on the (probably prior) forum but never got an answer.

I used to work for a company that used CNC machines to make robots for education and industrial training.
I had no interaction with them but was close to the owner who did the programming for them.

He once said he would never carve wood on a metal machine for fear that wood chips would get in crevices, get oiled, expand, and ruin calibration.

Thoughts?

[steamer]

Crueby

Mostly metal is what I'll be using it for.   Occasional thin plywood....but I can cover the lathe for that

Chips getting the ways would be problematic...and after all the work I did on Samantha...I'll make sure to take good care of her.

A 1/16 brass plate that needs some windows and irregularly shaped holes     Two ways to do it  Take the vise off the mill, Clamp the stock to a piece of plywood or aluminum and mill it on the mill, or use a scroll saw   With THIS saw it will be faster than the mill, unless it's ridiculously simple.
Thinner stock favors the saw even more....piercing saw blades work great!....and I can cut inside acute angles with the saw

Of course, there is always my trusty piercing saw.....and some patience.
Dave

[steamer]

The stock for the table came today.   It won't need much just a facing both sides, and bored hole for a zero clearance insert.

Racing this weekend....but more to come...

Dave, in post #20, what is the piece that looks like a home made "chicken stick" [plastic rod on the end of a wooden dowel]? Is it even part of the saw to be?

No...it's a tool used to put new tires on bandsaw wheels.   I had just finished doing that and it was on the bench

Dave

[steamer]

Ok some progress.  Need retainers to hold it all together when a blade breaks.  A crank and pitman arm.
