Re: 5C Collet Racks from the Tormach

Nice job and much better than the usual bent sheet metal 5C collet racks. Possibly my paranoia surfacing about rust problems, but I think I might seal at least the edges of each hole with some poly urethane or equivelent unless your 100% certain you won't have any future rust issues.

Re: Power

Yours is a fairly simple lathe as far as the electrical goes and doesn't have multiple contact switches to interface with a VFD. So it wouldn't be very complicated at all. It was an unbelievable eye opener the first time I started my 3 phase mill with a VFD. From what I've seen as far as smoothness ...

Re: ABOM sized lathe

Some of those steel mills had or used contractors that had massive lathes for turning the rolls used in the mills Mcostello. Youtube has a few videos up about turning those steel mill rolls. Even with carbide it's not a fast process. But 40'6" is I think the largest I've heard about for one single p...

Re: ABOM sized lathe

I have some drawing shown in a detailed book about smooth bore cannon casting and machining them long before steam power was used. Animal power or water power was used with a lot of the machine tool parts made from heavy oak timbers instead of the later cast iron. They show at least one example of v...

Re: ABOM sized lathe

If the carriage doesn't have a catwalk, table and chair on that for the machinist there small ones. :-) Mesta Machine Company has some good history scattered around the net of some very large equipment. I believe they made some of the largest forgeing presses ever built. There was a great book about...

Re: Please help me identify this Mini Lathe!

Likely home or small shop made is my best guess. Might have been a school or apprentice project as well. There's a vast difference between an actual restoration and just cleaning it up and laying a fresh coat of paint on it though.

Re: How do I use a shaper?

For shaper operation there's more than enough on Youtube to fill a month or two. They also seem to have a real love/hate relationship with people. Some think there a complete waste today. Yet the more you know about all they can do and the very little they can't the more useful they are. No they ain...

Re: DTI vs DI

Years ago I think I got very lucky and ran across a post mentioning something about Long Island Dial Indicator Repair and am a bit surprised no one's mentioned it here. They've changed there website a lot, but at one time sure didn't have much good to say about the Starrett Last Word Indicators. The...

Re: the newbie says Hi and a question.

My little non adjustable tailstock Emco compact 5 has what Emco calls leveling plates, basicaly the lathe head and tail stock ends get bolted to a plate at each end. On the outsides of those plates hollow bolts get screwed into the plates. Those make the adjustments for level and can twist the bed i...

Re: DTI vs DI

Starting from bar stock a .001" DI should be good enough for round stock in a 4 jaw independant since +- .001" shouldn't make a bit of difference. Re-algning a previously machined surface then your part and accuracy requirements dictates what level of perfection is needed. That said there's also sup...

Re: ww2

Not first hand knowledge. And how much it really helped the war I don't know. I've read a bit about people with home shops during that time doing small production runs of simple parts. South Bend for example came up with a design for a concrete bench top for those home shops that apparently made a l...
