Ruben, that was for you btw, about the steady rest! cheapest shipping possible, speed not issue. Jeff

You might say it has potential, but there again, potential (difference) seems to be what¡¯s missing.

What would shipping to Canada be? Jeff

This moment I have a steady rest for sale if you're interested. Price: €70,- I'm in the Netherlands.

Here is an armature lathe designed for use in a typical auto repair shop back in the day.? Another aspect is the need to undercut the mica insulators and that is the little attachment in back in the

Hilarious!

Back in the days when electrical interference was more of a problem than it is now, in that very little equipment was protected from it, it was found that one of the best ways to avoid mains borne

You sometimes see a rotating chuck for use in the tailstock - they were intended to support the end of a dynamo (or motor) when skimming the commutator. I dimly recall diamond tipped tools being used

There was (is?) a type of lathe called a "commutator lathe".? Their most typical application was most likely turning the commutators (cleaning them up) on automobile generators.? It was a pretty

Brilliant idea to turn your lathe into a generator! Just apply electricity to the commutator and then harvest power from the plug. Handy if you don¡¯t have, errm, electricity. Begin forwarded

Here's one I bought some years ago on eBay. I cannot find a better picture of it. Peter Brixey in sunny Florida.

You may be able to put some brass shim under the headstock if it is low relative to tailstock centre. John

Take the way bars off and check them for straightness? Maybe try them the other way up? Or even turn one around? I¡¯m not an expert on this, just thinking of easy things to check. My first thought

Another good point but I can't get over the description of the hole angling down. If the workpiece is in the headstock chuck there is no such thing as down. I can see getting a tapered hole but not an

I was thinking the same thing, bum drill-bit.? With a headstock/tailstock miss-alignment he would have always been turning tapers.

Good point Quinn, I've seen a number of new drill bits from Harbor Freight where the lips are not of equal length. This will cause a bit to wander. One visual clue of this condition is different

I am presuming the drill was mounted in the tail stock. If you can duplicate the set up, and the drill wanders downhill, repeat the set up and rotate the drill 90¡ã and see if it wanders in that

Part of the secret of Gun drills is the cooling. Not only does it cool the tool tip, but it aids in the removal of the chips. It is the buildup of chips that contributes to a twist drill wandering.
