Opus die filer

Hi daveb, The pulley system only controls file speeds, and the hand wheel operates the pulleys by a long vertical screw. I just don't see any adjustment device on the surface of the machine to vary the stroke length. I have a shaper, so I understand what you mean about the sliding block, which makes sense. I now think the adjustment is likely to be inside the main casting, which I'll check it out next time I'm at my storage unit; thanks for the tip.

Hi MikeE, to adjust the stroke you open the long narrow door at the upper left hand side, inside you'll see a flywheel with a 19mm spanner size nut with a bearing & a tee slot just like a shaping machine which you slide nearer the centre for a shorter stroke & outer for a longer stroke.

H Graham,

When the filer was delivered I noticed the narrow cover on the left side. I popped it open for a look, but couldn't see much as I didn't have a torch at the time; I'll check it out.

Cheers

I had a look today and was able to see the elongated slot in the flywheel where the connecting rod is attached. There doesn't appear to be any index marks to designate stroke length, so I guess you just adjust it by trial & error. Here is a photo.

Here is a photo of the filer's guide wheel & track.

And here is a view of crank and slider mechanism. It would be interesting to see an internal photo of Tractor Man's filer for comparison.
