Gilbert Erector thread sizes
« on: March 28, 2019, 10:27:33 pm »
I bought a bunch of pulleys cheap (a set of two)... But I need set screws. Any idea on the thread size?

Set Screws are part #S11 - 6-32 x 3/16"

From 1933-52 nickel plated steel

From 1951-62 cadmium plated steel

Thanks a bunch.

The 50s Erectors come with motors and gear boxes. In the cheapo 2 sets I got (only $5 a piece not including shipping) there are 3 gear boxes 2 with motors attached and 1 without. (The without will become a steam powered gearbox.)
Anyhow from the factory I noticed they used pan head set screws but they sometimes interfere with the gears. A dum dum design. I went to the hardware store and got #6 grub screws and it's much better.

The gear box gears should be beveled for better engaging...

Nick... From your chart, I have very early 50s sets. ;)
