Re: Scroll Saw Upper Blade Block

In this photo of a Scroll Saw from paulrussell there appears to be some additional mechanism on the upper blade block between the roll pin and part 18. I don't see that anywhere on the diagram, anyone know what it is? I have made multiple modifications to my scroll saw, including deleting the sprin...

Old catalogs? Anywhere?

I was wondering if the old 70s/80s Shopsmith catalogs are online anywhere. I wanted to do a bit of archeology.

Re: Scroll saw: 7/8", 1 3/32" , or 1 3/16" stroke length?

i toyed with buying a cam and shaft from a Teal model just to see how if it would work in my older saw, but it appears the part is significantly different, and the chances that it would balance with the other weights is slim -- and buying both is richer than I'm willing to go. By my measurements and...

Re: Scroll saw: 7/8", 1 3/32" , or 1 3/16" stroke length?

Is it possible the shorter stroke emerged with the self powered model? (requires less HP) Mine is the self-powered 555272 and the stroke is the 1 3/16" in the photos above. (I suspect mine is supposed to be 1 3/32" and the extra 3/32" is due to manufacturing tolerances) Also, the man...

Some possibly supporting data: The part number for the weighted cam, which determines the stroke, changed between the grey and teal versions.

Scroll saw: 7/8", 1 3/32" , or 1 3/16" stroke length?

There is a post by JSBurger describing his "Teal" scroll saw as having almost no vibration: https://forum.shopsmith.com/viewtopic.php?p=222280#p222280 Try as I might, while I have been able to greatly improve the smoothness of my scroll saw, above about 3/4 speed there is noticable vibrati...
