Re: Scale of the universe

Hello Harold,

Excellent! I've copied this and sent it most of my email list - helps to put things in perspective.

All the best,
Mike

Re: New members shop

Hello and Welcome! It looks as though you have a real nice workshop, almost too neat! Now you've joined the 'old iron' collectors club with that Benchmaster, I expect you'll be getting a bigger lathe to complement it. Looks like you might do some work on older clocks as well. I've had a Benchmaster ...

Re: Newbie - How to Adjust Gibbs?

Hello TheReck, The gib should not be moving in and out of the carrier - although i'm not sure what you mean by that. If it is extending out beyond the ends of the compound, something is wrong. I'd suggest you download the manual (or send me a PM and I'll send you a copy in pdf) to get an idea of how...

Re: Newbie - How to Adjust Gibbs?

Hello TheReck, Perhaps I can shed a bit of light on this - I have a Maximat V10P. The one 'cap-screw' in the middle is supposed to lock up the compound to the carriage - if yours isn't working without really cranking it down, it likely is missing the ball bearing at the contact point. The other sets...

Re: Harold V's Tool Grinding Tutorials Compilation

Hello Chet, Stumbled on this and the topic looked interesting - I've had no joy getting it to download - not even a big Download Button! Anyway, found this via Google and I think it's what we were both looking for http://twoloonscoffee.com/download/Tool_Grinding_by_Harold.pdf Let me know if you have...

Re: OK... what did I do wrong.

Hello all, I can feel your pain! Only within the last week or so have I discovered why I've been struggling with threading on my Emco Maier Maximat - a high quality Austrian machine. Same situation with the compound protractor having a zero set 90° different from my previous lathes (all American man...

Re: Maximat Mill Problem

Hello Harold, I guess the PTFE filled material would provide a better coefficient of friction, but I wonder if it would change the melting point much? Just checked and the MP on both is 347°F so it should be fine. When I make the Acme nut I'll definitely use this process, but that won't happen as lo...

Re: Maximat Mill Problem

Hello Harold, I don't believe it was a 5/8 thread - I sure can't find anything that diameter with the 16 TPI so it would appear this was either custom or in-house production. As to why? I can only guess it was to provide the fine control on the 'Z' axis of the mill, with 0.0005" per increment. I can...

Re: Maximat Mill Problem

Hello Harold, No idea why they did what they did, but there is no doubt the TPI is 16 and the diameter is 0.588" - the movement of the head is 0.0625" per revolution, and the graduated dial is indexed to reflect that, i.e. 62.5 increments. I'd bet it was unique to Emco Maier and either custom made o...

Re: Maximat Mill Problem

Hello all, I appreciate you are probably sick of my problem with the graduated dial not matching actual movement; Heck! I've been wasting the whole day on this! Finally figured it out: on re-re-checking the indicated movement vs. the actual, I noticed they matched perfectly with the movements from 0...

Re: Maximat Mill Problem

Hello Torch, Your math is correct and I've been thinking about the obvious variance between the graduated dial and the actual movement, so decided I had to re-check taking greater pains to ensure I hadn't missed something. I checked it with both a digital (Mitutoyo Absolute) and another quality dial...

Re: Maximat Mill Problem

Hello Rick, Thanks for the response. From another forum I had a suggestion to measure the movement of the head based on one full turn of the graduated dial - 0.0625". I think we can assume it's a metric shaft, 15 mm X 1.5 pitch. The curious thing that should have been a clue - the graduated dial is ...
