Dimensions of 45 idler wheel for ROK Challenger/Imperial

This is where record cutters raise questions about cutting, and trade wisdom and experiment results. We love Scully, Neumann, Presto, & Rek-O-Kut lathes and Wilcox-Gay Recordios (among others). We are excited by the various modern pro and semi-pro systems, too, in production and development. We use strange, extinct disc-based dictation machines. And other stuff, too.

Does anyone here know the dimensions of a 45 rpm idler wheel for a Rek-o-Kut Challenger? I had been looking to buy one but I’ve had no luck finding it, so now I’m shifting my aim to fabricating one if I’m able to find the dimensions. (Though if someone here DOES have one for sale, I’d happily forget all about making one, haha 😵💫) Thank you.

Hi, Sean.

If the Challenger uses the TR43H turntable base, I've got one that runs 33/45 and could photograph the drive puck and measure the dimensions for you if that would help. Make sure that yours has the 'H' suffix, meaning a hysteresis-synchronous motor; it could be that the less expensive lathes used a square, 4-pole motor that "slips" and runs a bit slower than 1800 r.p.m. I don't know if Rek-O-Kut did that (I'd be surprised if they would stoops so low), but it would be a consideration. Probably best to direct-message me on the Trolls site; this is a busy topic area easy to get lost in. -Jim
