Topic tags/keywords: question tablesaw unisaw

Does anybody know what size the 2 holes in the back of the table are for a 1986ish vintage Unisaw?

Trying to work up a mount for a cheap out-feed table I got that was missing it’s legs. Planning on putting some all-thread in the holes & drilling matching ones in the out-feed table & mounting it with wing nuts. However my hardware supply is lacking & I don’t have anything handy I can use to determine the size/pitch to get.

Are they threaded?

Those might be metric. If you have (or can get) your owners manual, it should tell you the size.

You could also find another bolt from the saw that fits those holes and take it to a hardware store. They usually have the gauges you need to match bolts.

I pulled a couple bolts off this weekend, and none of them seemed to fit the holes. Ordered a set of thread gauges but those won’t be here for a bit.

Unfortunately the closest thing I have to a manual is http://www.owwm.com/pubs/1141/539.pdf, which doesn’t help on this front.

‘86 was still a made in the US model. If you can send me a model and serial number I probably have the exploded art with part numbers,and perhaps sizes. I have the service manuals going back several decades.

Serial # 88c16968 (there’s a chance the last 8 is actually a 6, as it was double stamped & hard to read)

Cat. No. 34-802

Were the other bolts even close? Those holes might be gunked up enough so that even the right bolt won’t thread in.

A tap and die set might be useful. If you’re careful (i.e. don’t force it), the right tap will clean up the threads without messing them up.

Nope, wrong size, either way to small or way to big.

Have your say...
