The Spiders were used on various steppers and roto-targets. They can be difficult to take off because the softer metal shaft gets mullered by the grub screws and expands the fixing shaft where they bite into it. So this puller is a good thing to have in your toolbox
Very Nice. Could have used this last week when I rebuilt a roto target unit on a Criss Cross. Really struggled to get the shaft out.
Quoted from Carlo45:Really struggled to get the shaft out.
Getting the shaft out is another issue. After removing the spider, you have to dress the burrs on the shaft with a fine file in most cases.
Quoted from jrpinball:Used a nut, bolt and washer to make a puller.
How is this different than your typical bearing or steering wheel puller?

For me, the difference was I didn't have anything else, so as they say, necessity is the mother of invention.
Please forgive me Joe for imposing on your thread. However when I read it last weekend it provided inspiration to finally solve the pesky "where are those damn cotton buds" which I frequently use during restos. First a rough template then a sheet metal dispenser which slides under my tool cabinet. Thanks for the inspiration!
