I am in the process of making a few pair of O1 file guides (1/2" x 5/8" O1 stock, stainless screws and pins). I have the sets nearly complete and was wondering if I could do the heat treat when each pair is fully assembled and bolted together. If I did this I would not peen in the pins, but instead keep them loose then after the heat treat swap out the screws and use new pins.

I was thinking this may help to 1) keep everything straight and 2) keep scale off the inside surfaces. I would appreciate any input you may have....is it a bad idea to heat treat the assembed guide for some reason?

Thanks

I would heat treat separately. O1 is pretty dimensionally stable, and you will have to clean up the decarb anyway.
 
I concur with Warren. Do them separately. Once done heat treating.....clean off the scale and grind off any decarb. Then re-assemble the guide, tighten the screws down, and then true the face up (and inside flats too if you'd like). Just remember to temper the guide....maybe around 300F or so??? I made the mistake of making my first guide out of W2 that was water quenched and NOT tempered. Needless to say...the first time I torqued on it....SNAP! My current guide was tempered at around 325F and it is going strong.
 
Good deal, I will do them seperately. I planned on tempering at 300F, and was hoping that would give me around 64 R. Thanks
