Topic tags/keywords: miter box millers falls replacement parts lock pin restoration

I picked up an All Steel miter box by Millers Falls, cleaned it up and now it’s really nice. The locking pin seized, but I was able to move it in a vise. However, once on the miter box it is unmovable.

Where can I find a replacement locking pin?

Or how can I fix this one?

The locking pin is what secures the lever at the desired angle. If it doesn’t work the miter box is useless.
Or how can I fix this one? I’ve tried massive amounts of PB Buster, butt I think it has done all it can do.

I’ve heard acetone/ ATF mix works wonders.

Have you tried any heat to the area?

I have not tried heat. I don’t know what the inside of the locking pin holds. Do you think it is a broken spring or just a dirty rusted interior? If it’s a broken spring I would need disassemble right? I don’t know the proper way to disassemble one of these.

This is the pin fully pushed through.

So I’m just curious, what, if anything, was the final outcome?

I assume this pin is from under the swing arm, is it not? Looks way too big to be from the Saw Guide Posts.

The pins on my Goodell All Steel look different than this.

I recently acquired a nice Miller Falls Langdon Acme 74C Miter Box and it is missing a 16847 Depth Gauge Screw. I have one but am missing the other one. Does anyone know where I can find a replacement depth gauge screw? I am nearing completion of the restroration and would like to have the miter box in top notch working condition.

I’m wondering the outcome as well. Looks like from the picture a good rubbing with some steelwool would have cleaned that pin.

Hey JethroBodean and JoeinGa, thank you for checking in. I didn’t post my results as I didn’t think there was much interest.

The internal mechanism was not what i thought it would be. I thought there was a spring of some sort. There was nothing. Just the pin and the nut. I pushed the pin out by offsetting the nut in a vice and cranking it. You can see this in the pic above. Once it was flush i stuck a bolt in there and used that against the vice until the pin popped out the other side. A few strokes with some fine grit sand paper and smooth steel wool was enough to clean it and ensure it slides smoothly through the nut. Works great now.
