Fairchild 740 lathe need advice and help...

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.

Fairchild 740 lathe need advice and help...

Hi I have recently got hold of a Fairchild 740 lathe, I was wondering if anyone had one of these and if they could give me any background info on it.

Image

It came with a British made MOY Type B1/A B.B.C mono feedback cutterhead that takes a Fairchild/Presto Longshank styli. Any info on this would be great.

Image

There are a few things wrong with it at the moment that I think are pretty simple to solve, namely, the belt is loose and the electrics that power the motor seem to turn themselves off after a few minutes... apart from that the cutting mechanism seems to work well.

It came with no cutter or feedback amps so any advice on what to replace it with would be great!

Thanks!

Same one yes. Am thinking of replacing the head with a Vinylium SC99. Only just getting up and running to a testing stage.

Nice lathe, BongoJim; any other pics you could possibly post to the forum of the feedscrew and cutterhead transport assembly, if not too much trouble, would be greatly appreciated.

Always fun to see new, different approaches to building a lathe.

I wonder if there are any Fairchild 641 stereo cutting systems still operating anywhere? I have seen parts of it including the transmitting tube type cutting amps and I think I saw the lathe once. The head is the most interesting part in that it has a lateral coil and a vertical coil. You feed it sum and diference signals rather than Left and Right. I think that is why there is a switch for this on their famous 670 limiter which I guess was also part of the system. For some reason they chose to use an rf signal which the feedback coils modulated for their feedback scheme.
A very "outside the box" design. Some 60s Dot and I think Vanguard records credit it on the back cover.

Awesome B-Jim, you're the man, thanks. Great details.

Love the design of making it so you simply turn the screw heads on the turntable to channel the suction for different diameters. Brilliantly simple; would be much easier to machine, compared to other designs.

Hey I saw on your pictures that you put a record player under the 740 bridge. Did you have any problems with the original configuration? How is the bridge driven anyway? Does it come with a special motor for the lead screw?
