Lost T slot washer

UGH! One of my miter bars (SS Mark 520) has lost its washer and screw that holds it to the bar. Is this metric? Anybody know the sizes I need to get, hopefully at the local hardware store?

I would be interested if you can find them locally. I have bought them from Shopsmith, item 514376, currently at $2.27 a copy.

I seriously doubt that you will find those parts in a typical hardware store.

The two parts that you need are:

Washer(283).......514376 $2.27
Screw(284)..........514377 $0.80

If placing an order, I recommend you lay in a spare:

Taper Screw(279)...501401 $3.53

I knew the parts from SS were inexpensive, it's the dang shipping cost that makes me hope to find a local source.

Thanks guys.

Dusty - what is the taper screw used for? Is that the screw for the miter bar?

Yes, the screw that is used to lock the miter bar in position.

So order something big(heavy) and not very expensive(wishful thinking?) and the additional shipping cost for that 'hardware' will be undetectable!:D

The thread is 8-32.
A washer about 7/8" od and about 0.115" thick and having a counter sink center hole to accept a 8-32 x very short(3/8"?) flat head screw.
To prevent loosening, slightly jam the screw threads or use blue locktite.

Putting flats on opposite sides of the washer(width about 0.725) would allow rotating the washer to allow insertion in non-t slots with out totally removing the washer&screw.

Food for thought!:)

Thanks JPG,

Customer service said the PowerPro headstock was heavy so I ordered that! Oops, already done that one. LOL

Thanks for the details. I'm headed up to my local hardware shop. Old fashioned wooden floors. I've never stumped him yet. We'll see.

Good idea on flattening the washer sides!

Put Flats on the Sides? Why? Where do you find that this might be useful other than on the Belt Sander Table?

I hope he takes the miter bar with him to the hardware store? The washers in mine are thinner.
