WANTED: Columbia Crank

Post by Jwb88 »

Looking for a crank for my Columbia late model BN. Several styles will work and I'm not picky, it just needs to have a 7/16" diameter outer shaft and standard Columbia female threads inside (around 5/16" diameter hole). Also, the throw needs to be 3 ¼" or less, otherwise it (along with my hand) hits the surface that the graphophone sits upon. See example photo with measurements but keep in mind that I used a different crank so it's not to scale.

Any and all help is greatly appreciated! I love this machine and it's time for a proper crank. Thanks!

Tom at Gramps Treaures (the grill guy) made a small run of these. They are perfect in every way.
You might need to ask him about them if they are not on his website.

That's promising! Thank you! I'll email him. Although the one pictured on his site is obviously much too long.

I PM'd you through Facebook.

Sadly the one offered is too large. Anyone have the size I'm looking for?
