| Andrew Wildman:
Having scratched my head for a project, what I have come up with is a die filer. I want to make a simple one along the lines of the MLA one shown in this link (not my machine obviously!) http://www.clickspringprojects.com/die-filer-or-bench-filing-machine.html It does not need much grunt as I will just be using it for things like finishing square holes and sharp corners in plate. This means I wont be bothering with an overarm guide or a workpiece holding down arm. As with most of my projects the filer will be based around what is in the scrap pile, so no castings. I would like to scratch the collective head with a few questions though: What kind of strokes per minute/second should I be aiming at? Is it worth making the thing variable stroke, if not what stroke is optimum? I was planning to make the files by cutting up parallel sections of cheepo files and mounting them in a v block type arrangement so that they cut on the down stroke. Does this seem reasonable? I would appreciate any thoughts... :smart: |

hi looks good I did see sum time back a set of plans to make one out a old grass cuter side valve engine |

A fie filer is also on my list. I'm planning to repurpose a cordless recipro saw I purchased without battery at a club auction. Hopefully I can reuse the original variable speed control with a mains power supply. |

I had a bit of a fiddle about in the shed today. I mustered up a crank and a yoke and a bush. I decided not to do a fancy variable stroke adjuster, though I have made the stroke simply adjustable and just made a few different crank peg locations at different radii. this is the progress so far including a bit of bar that I faced for the base and what will become the bearing support for the shaft: The rest of the build will be made from 60X12 flat bar that I have a lot of and some 15mm alu plate that I picked up from a boot fair. I have stretched the budget and purchased some bronze bushes for the rotary part and the linear part. |

I got a bit of shed time yesterday so I started work on the body of the die filer. I decided to change the design and build it so that it can fit on the smaller lathe so that I do not need to make a drive system for it. Bolting it to 500kg of cast iron will also stop it jumping about as much. I cut and milled the ends of some bar and then glued them together. The frame still needs some bits adding but here is the basic shape This is the frame posed on the lathe. I will mill the critical features after the fabrication is done |
