Time for a new project. I will be building a Die Filer. This will be a larger one than most of you are used to seeing. The Table will measure 14.000 X 14.000. It will be 16.000 tall. A "Scotch Yoke" will be utilized to convert the circular motion to linear motion of the file. The Table will also tilt forward 45 degrees.

Here are a couple of pix of the Table Trunnions ready to be cut. They must be the same so they are bolted together. The 4 inch diameter piece bolted to that is to mount them off center by .625 inches in the rotary table.

I am getting together with bill50 to do the prints in CAD and PDF for all to download if they want.

Locked in and ready to cut. Need to clean first though. The last job sure was a messy one. LOL

I have been spending the whole week cleaning and reorganizing my shop area. I seem to be finding room for more stuff now.

I've been wanting a die filer. Looked at a couple of casting kits but I've got another major project going that will take until at least the end of this month, and probably until the middle of next month (when it is required to be done :). I'm looking forward to seeing your build, and the resulting prints.

Started the machining only to find out the swing maxed out and hit the mill tower. Easy fix. I just cut the corners off the blank. Still close but it clears.

Billy- I built one of these recently. I made my Scotch Yoke as an open frame design. It works but it can be noisy when running. I should have made an enclosed design and run it in an oil bath. I can put up some pics if you want. What design are you planning?

Rotary motion to linear motion will be thru a "Scotch Yoke". It will also be open frame except for the Plexiglas cover.

Gunrunner you need to order a set of these for the Z axis hand crank. Bill did you just spit coffee on your monitor? :rofl:

Those are small. The Table on mine will be 14 X 14 inches. It will be over 17 inches Tall. Nice though. I believe both are available as castings?

Following along for sure. I never knew I needed a filer until I saw one in action. Thanks for the detailed build thread.

Do they use special files?

Yes Charles. They are shorter and have straight round tangs. Google Parallel Machine Files.

This part is next. It is the guide for the Trunnion. Two are needed and they are mirror images, 1 left, 1 right..102_0899 (800 x 531).jpg

Frame roughed in. Many holes to drill and tap in the back and sides. Frame measures 3.250 X 8.000 X 15.750 inches. As I said, this is not your everyday Die-Filer.

I have been using conventional files in my filer. It only has about a 1.25" throw. I cut the tapered tips off the file and keep the parallel part. I mount it inverted so it cuts on the downstroke. Some files lend themselves to this more readily than others based on their profile.
I use and old hand tightening drill chuck to mount the files on the shaft. It seems to work fine and is "quick change." Bill, I'm sure you will come up with something more sophisticated than that!
Hey are you cutting the aluminum plate on that table saw?
Watching intently.

I gave it a try for the first time. I won't cut aluminum on the Table Saw again. Too many things can go wrong in a real hurry.

Thank you for this post, Bill! I had looked at the cast kit that rwm posted the pic of (available thru Metal Lathe in Pine Grove, Pennsylvania), but this looks like a very tasty alternative! Please keep us posted.

I have a table saw set up with a special aluminum blade. I have cut up to 1". I know what you mean about something going wrong. It's a scary process. I am always afraid the blade is going to bind and launch a piece of metal at me!

As said, the files are kinda special and not your normal garden variety. You want the file to cut on the down stroke. And it would be best to have files with parallel sides so it files square or the same path on the full stroke. As far as holding the files in the machine, to each his own. I have a factory made die filer and it can chuck/hold just about any shape you give it. If you are looking for round files, say in the 3/16” round size a good source for them is to use a chainsaw file. Other than that, it’s the auction stuff on the internet for die files or pay the price for new. I’m always looking for files for my machine and it’s really hard to find any garden variety that’s gonna work…Good Luck, Dave.

How does this look? The file is complete, all 15 drawings. I need to import it to my computer.

Love your drawings Bill, as I can actually make sense of them (they actually look like drawings I saw back in Drafting Class). :)

The more modern notation (and that used for the Quorn and Bonelle) doesn't. Progress.
