Tubal cain also has quite a few videos on youtube, covering mostly lathe work but I also think he does some milling videos too... Actually there are quite a few people posting videos on youtube

Buying is often cheaper than making, but it's good to know how to make. Look up the thread specs of the NPT. Set your lathe and cut that thread on the, but straight rather than tapered. Now use a

The famous Model T Ford had 1/2" pipe threaded sparkplugs. The plumber's diestock I have has 2' long handles on it, and is not at al hard to turn. Mert

Actually, you can, somewhat. I think in Lathe Handbook #1 (one of the old-time machinist lathe-tips books I got from Lindsay Publications), someone with a similar problem cut taper threads by cutting

Old flywheel style single cylinder gasoline farm engines mostly used 1/2" pipe threaded spark plugs. (Made after the low tention spark-points in the cylinder chamber, & before the high speed air

Thanks Roy, and they're free too :-) I'll take advantage of these. Ron

MIT has produced a pretty good set of videos to help prevent rust damage (from student blood) to their shop machines: http://ttv.mit.edu/videos/142-machine-shop-1 Roy

With an OD of 5/16" it's 1/16" NPT. Both 1/16" & 1/8" NPT are 27 tpi. Straight pipe threads are used for electrical stuff; conduit fittings are threaded NPS as are lamp parts. Roy

Andy or Abdy as you signed your self recently As the tool pivots on the cross slide mount you can cut a keyway slot in tapered shaft or hole. Malcolm ? I don't suffer from insanity I enjoy it! Mene,

Cost is relative, what price experience gained in making something. If you are experienced and the tool is for a commercial usage, then spending time making something is a false economy, unless of

An excellent video, Malcolm. I suppose your tool can be used to broach the corresponding keyway into a shaft, provided there isn't so much sticking out of the chuck that flex becomes a problem. Andy

Very neat. Now replace the handle with an air cylinder and "automate" the motion so all you do is manage the cutting depth. mparkerlisberg@...> wrote: -- Bruce NJ

The Uni DB/SLs Can be set up to turn tapered pipe threads with the factory threading att., but only if the pitch needed is one that was supplied by Emco. Of course one could make a thread master for

I have a 6" Metabo slicer, which is specifically designed as a cutoff saw. it works beautifully on the lathe. place a piece of tin, or other rigid non-flammable item under the blade, to keep sparks,
