Re: Machining Setup's with Few Comments

Self-cleaning ovens get to 500C. That's enough for annealing. While 500°C can temper (draw) ferrous heat treated items, it is far too low to anneal. I make mention for those who may have need for true annealing. For that, you must exceed 750°C (each alloy has its own requirements). The lower temper...

Re: OT: Building in isolated location

It may already be in your plans Bill. But I had a couple of close relatives living off the paved path. They both said the same thing. Having a paved or concrete driveway would save a massive amount of air born dust, mud, snow and whatever tracked up to and at least into the entry way or into the gar...

Re: Machining Setup's with Few Comments

Nicely done Carrdo. One trick I picked up from a few welders mentioning it to me was to drop the part from 2"-3" up onto concrete or steel multiple tmes to help release built in stresses. Beating it with a hammer can help do the same if the parts oversize enough to machine off the apprentice marks. ...

Re: Micro torch?

The old cliche is that's it's a poor workman/woman who blames there tools. My view is if they can afford better whenever possible then poor tools aren't used to begin with. And the more a person cares about the end result the less likely they are to settle for less. While there's some brands that ar...

Re: Questions about new DRO

I can't say for sure about the 6" x 26" since I don't own one, but there all pretty simple. Just in case I bagged and tagged the parts for each end of the table so they all went back into the same place. After you get the feed screw out then pull the gib and the table should slde right off. Support ...

Re: Questions about new DRO

I think I'm the same and always like getting as much information as possible on something as critical as installing a DRO Ron. From what I've seen and did with my mill after getting it I highly recommend at least pulling the table with any new or used mill. I'd certainly do so even with a brand new ...

Re: Questions about new DRO

Fwiw some years ago I saw one of the best and well thought out DRO installations on one of the machinist forums for a Bridgeport type mill but can't recall where it was. The poster did mount his X axis on the front of the table, managed to keep the table locks and power feed adjustable limit stops. ...

Re: Jet Vertical mill a clone of a Bridgeport?

I'm a little late to this since it apperars you've got it all back together and working. So fwiw Jet as far as I know doesn't actually manufacter anything. There a high volume dealer much like Grizzly and many others around the world who sell enough to have the factorys building the machines paint a...

Re: Mic standards or gauge blocks

I forget what the industry standard + - tolerence is for micrometer standards, but there way looser than gage block limits are. Used, worn or offshore built mike standards may or may not be even further out if there not checked. I started my working career in a coal testing lab and one life lesson I...

Re: Self-ejecting chuck keys Y/N

I'm positive your right about what happens with those spring loaded drill chuck keys Conrad. I tried one for awhile shortly after getting my then new floor model drill press just to see if I could adapt and get used to it. Because of the key's teeth constantly being pushed in/out and that engagement...

Re: Self-ejecting chuck keys Y/N

Yep, if you didn't retrain yourself after the first or at the very most second time forgetting the key then anything mechanical might not be in your best interests. I'm all for making things safe as anyone should be, but it's common sense that it's impossible to totaly idiot proof anything. Drill an...
