"fixed the die filer"
I finally found the solution as to the Milwaukee die filer with the loose plunger.
Solution was to buy an Oliver Instrument filer out of the want ads! Floorstand model, nuce cast iron stand with filer and motor on a sort of cast tray.
Needs a motor, but the plunger is in good shape and it has the overarm etc.
I cleaned it off, but any more work will have to wait until after NAMM, most likely.
Congrats on the new toy! Which model is it?
Sometimes replacement is just a better solution than repair.

It's an SP-2. Needs a motor, and teh moron who took off the old one tossed the 2 step pulley also. I will have to figure out what it is.
Seems like these must have either had very fast strokes, or else 1140 RPM motors. Even with a 1 1/4 pulley (small for a 1/2" v belt) it is 255 strokes per minute, with a faster speed also available.
I posted at PM looking for the info, but the posting part of that board is AFU and I might not see much on it for a while.
Looks like this

I purchased exactly the same die filer from a guy in Dayton Ohio about 5 weeks ago. Found it in the want ads and paid all of $75.00 for it. Problem is, the files seem to be pricy and hard to find. You can use regular files in it but genuine parallel machine files are best. Federal File still sells them. I have about two dozen various 8" parallel machine files that I purchased off ebay. I have a lot more invested in the files than the machine now. They are all new old stock, mostly Nicholson and DoAll. I have already used the machine to produce two square holes in the Mueller No. 1 Rifle action I am working on. It was a lot easier than the tool Mueller described in his book. My machine is complete and looks original but it is not as clean as yours. I should be able to get you information on the motor and pullys but I am at work right now.

J Tiers - Oliver of Adrian or Oliver Instrument Company is still in business in Adrian, Michigan. Their prices are very reasonable, except for the files. That pulley will only cost about $20, I bet. They have a website www.oliverinstrument.com and are deserving of our support - good old American company! Just a satisfied customer with 6 Oliver machines! A.T.
ttok...you have several Oliver machines? Presumably a filing machine is one of them?
What sort of stroke rate do they operate at?
I have 1725 and 1140 rpm motors, but all the calculations of pulley size etc are coming out at some really high rates....unless I use a really small pulley and 1140 rpm motor.
With the sizes I have been told, 1 1/2 inch and around 2.2, the speeds with 1725 would be 300 and 450 strokes per minute.
Seems really fast, compared to the old Milwaukee. On the other hand, the milwaukee has a much longer stroke, 3" or so vs 1 1/2 or so for the Oliver. That could affect the speed, figuring total teeth past the work per minute...
At 1140, it would be more reasonable, 200 and 300 (approx) with those pulleys. Those sizes come out to about the same belt length, although it looks like there is no provision for the quick speed swap capability that the Milwaukee has. It has a pulley groove setup that allows an easy no-wrench belt movement.
Maybe Oliver would have a manual copy, and all this would be settled.....
Thanks for the brain boost. I just figured they would be out of sight on price....like S-B, Cinci, etc. They have been emailed...we'll see.

J Tiers - Yes, (4) of my Oliver machines are die filers! Like an idiot, I bought a brand new S-4 bench die filer from them directly in 1994 - before I ever heard of Ebay - paid $2,200 for it!! It was new in the crate and paperwork with it indicated it may have been made in 1946. Then I found Ebay and bought what I thought was a junker S-4 (turned out to be in new condition) for $175 or so for a parts supply for the first one. Well, Oliver makes two types of overarms - one for a saw and one for a file rest, and I had both when I got the first die filer, so I put one on each and love them both! I have cut 1/4" steel plate for roof trusses in our house, all kinds of steel and brass, and filed a little too. Mostly use them instead of a band saw - take up a lot less room, and I do not have that much cutting to do. Hobby!!
A year later, I saw an old and very large die filer, 800 lbs. heavy, called an Improved die filer by Oliver. It was on Ebay, and I bought it and trailered it down from Colorado (was going there anyway). Two years ago, I bought a second large die filer for parts for the first one - it was in Albuquerque. These big ones are 3-phase, and I do not have them moved into place yet in the garage so I can plug them in. Other two Oliver machines are drill pointers.
Anyway, the SP-2 is what you have - it is really an S-4 on a neat (envy) cast pedestal.
They are driven by a two-speed - 1/4 Hp motor (both GE 1750 rpm, 110 v., with 2-step pulleys) - 315 and 430 strokes per minute. I usually use mine on the higher speed for sawing. Stroke is 1-3/8", and they are rated to cut tool steel up to 1" thick. I think they are made to leak a little oil - my brand new one did - same as the second one did - to keep fines out of the gearbox (really a crankcase). They will last forever if you check the oil - instructions say you must add oil every time you use them - at the start of the day. Take out the bottom oil plug (on the left side of the crankcase and add oil thru the top plug until oil starts coming out the bottom hole. Then replace the plugs.
I have the instruction booklet from Oliver if you need a copy. They want $20 for a copy, I think. They have all the parts available and they are probably reasonably priced. I do not have a price list. Each overarm, whether spring-loaded or simple file rest, is $220, as I recall.
One thing about sawing or filing on them - lean the saw or file a slight bit toward the front (operator) from vertical at the top when you clamp it in. This will let it cut more on the downstroke and drag the sawblade/file less on the upstroke.
The heavy Improved die filer is made with a hydraulic pusher on the table which pushes only when the file/saw is on the downstroke! How neat is that!! Cannot wait to see how that works!! One of these big ones sold on Ebay earlier this week for under $300, but they are top-heavy and a real pain to transport!
I am at work, and the S-4's anr in my garage at home. Will have to answer any more of your question tomorrow! A.T.
Ah! Good information, thank you.
I will be OOT until Sunday at a trade show, so no rush on more info.....I appreciate it.
I wonder how the saw overarm differs? This one could be used for either, I would think.
Jaws are flat, moving one is like a hook-bolt, and have a small "V" cut in them for round or triangle files.
What exactly is a "die filer" used for? or is it the obvious answer.
This thread is producing a lot of good information. I took a moment to check my machine which is exactly like the one pictured earlier in this thread. The motor is 1/4 hp, 1725 rpm, single phase. The smaller 2 step pully on the motor is a 1-1/2" by 2-1/2". The larger 2 step pully on the crankcase is a 7-1/2" by 8". I didn't take time to calculate the number of strokes per minute. Seems like I am using mine on the faster speed most of the time. Hope this helps.
