I bought one at a rummage sale once for $75 and it was an excellent little 4". I forget the bed length, I think it was around 18". It was a old Atlas that Sears sold as a Craftsman probably from the 50s to 60s. It was all metal not like the piece of s*** they switched to that had a lot plastic parts.

By the way, also avoid like the plague the little atlas lathe that sears used to sell - it is one of the worst of the worst. -----Original Message----- From: Tesla [mailto:tesla-bounces@xxxxxxxxxx] On Behalf Of Jonathan Peakall Sent: Wednesday, December 23, 2015 5:32 PM To: Tesla Coil Mailing List <tesla@xxxxxxxxxx> Subject: Re: [TCML] Wanted tabletop metal lathe I agree, and you just saved me a good bit of typing. I have a china lathe and it is quite useful for some things and other things I do on my friends "real" lathe. I have no room or money, so it is a lot better than nothjing for me.
