Re: [TCML] SRSG vs. RQSG (Sucker Gaps)



Hi Brandon,

The photo from my site that you referenced is something I build before the
propeller gap that did NOT work out.  The simplicity of a propeller gap
makes it a winner over any disk-based design, IMO.  And since I was using a
relatively small Teletype motor, I had a lot of trouble making the disk and
electrodes small and light enough that it would start up reliably.  The
propeller gap had no such trouble.

FYI - the link you posted is hosted on my old ISP's server - I didn't even
think it was still there.  If they ever get around to deleting data from
expired accounts, know that my current ISP has my sync gap page at
http://www.laushaus.com/tesla/sync_gap.htm
