The yoke lock on my 70's vintage B&D "DeWalt" radial arm saw kept loosening.
After much fiddling, it became apparent that the adjustment washer internal
tab had broken off. The tab rides in a groove in the king bolt.
Of course DeWalt didn't have the part, and advised me to call Wolfe
Machinery. The wanted $15 for this stamped-out sheetmetal 2" diameter piece
and $7 for shipping a 0.5 oz. item.
I did order the part from Original Saw Company. They had a minimum $15 order
policy, but gave me a "deal" and sold the part for $10 and "a couple bucks
shipping". The total came to $17.29 as my Visa statement shows, however.
After ordering the part, I took the old washer and made a new tab on it.
This kludge worked. So if anyone is in the market for this vintage part, I
could let it go for my minimum order fee of $100 plus S&H, and applicable
municipal, county, and state taxes, of course.
