I recently bought a early - mid 90s Powermatic 66 from a fellow forum member and am in the process of cleaning/lubing internals, building a dust chute, and other similar things under the hood before I mount the cast iron table back on the cabinet and dial it in for square.
Unfortunately, none of the Beis fence hardware could be located at the time of the sale. I am trying to piece together what bolts, screws, nuts, washers, etc I need to mount the fence rails to the saw. I will be building a wooden extension table to the right of the blade to accommodate the full 52" ? fence rail/tube, but I would like to at least get some bolts/screws in the threaded holes in the front (and back) of the cast iron table and ext wings.
It appears that the threaded holes in the front edge of the cast iron table are 5/16" coarse threaded. The holes in the fence rails are slightly smaller than that, bc the 5/16 bolt that I tried the other day was just a bit too big to go through the rail holes.
I'm trying to find bolts that have the tapered heads (like wood screws) that flush up with the tapered holes in the fence rail so that the fence itself slides smoothly along the tube and rail and doesn't catch on anything sticking out. Do I need the bolts to be sized properly to be threaded into the holes in the side of the table or can I go undersized and use a crush washer and nut on the back side?
Just to be clear, I am assuming the thicker of the 2 fence rails belongs on the front of the saw, correct?
I currently have a Bies fence set up on another saw but there is a wooden "rail" on the underside of the table that extends into the side extension table. The entire fence rail is mounted into the wood rail with wood screws with the heads flushed up into the tapered holes in the fence rail.
What am I missing here? I'm not very experienced with setting up a Bies fence directly to the cast iron table. Looking for any direction.
I can provide pics later if helpful.
Also, what fasteners should I use to secure the fence tube to the rail? The tube already has 3/16"? holes drilled into the bottom of it at different points.
Thanks!
