Re: Beveling an edge on a piece of plate

Hmmm. While I see multiple responses that allude to an angle being machined, you've not mentioned that is the case*. If not, you have an option that has not been addressed, one that permits machining the edge without moving the piece. Simply rotate the turret. That will work only if you aren't tilti...

Thanks, I think that I will give the vinegar a try.
It is likely a good choice, as vinegar is used to descale coffee makers, and that appears to be one of your intentions.

Re: Let's cleanup that old boiler

One thing to keep in mind. Sodium hydroxide has the potential to blind a person, something I learned when I splashed a drop of nitric acid into my right eye, many years ago. The drop of acid resulting in an almost instant destruction of the surface of the eye, in spite of the fact that I was very ne...

Re: Let's cleanup that old boiler

Uhhh---there's no muriatic (hydrochloric acid) in Coke. It most likely contains citric acid--but it might also be phosphoric acid.

Salt and vinegar will also dissolve rust, as will molasses. I've used both methods with success. Don't know what they would do for other deposits, though.

Re: Determining an angle of a blind pocket ?

Sealing wax has been used to determine such features. I've not tried it, however.

Re: Ellis dividing head collets

question: how come DH tailstocks are not adjustable side to side, like lathe tailstocks? Seems like one still needs to align DH work along the axis properly. So far,haven’t seen one DH tailstock that does this... My guess is because the dividing head is generally used on another tool that has movem...

Re: Looking for D1-2 chucks for a Pratt a d Whitney 1689

Nyle, I hadn't noticed the error on the chart, but you have to be right, as the difference stated between a D1-3 and a D1-4 is only a few thou. Having operated machines with each of those, I know that's not correct. The D1-3 is noticeably smaller, as must be the D1-2. I'm now used to the D1-4, as th...

Re: Looking for D1-2 chucks for a Pratt a d Whitney 1689

Thanks for that, Russ. For what ever reason, I had overlooked that bit of information. Don't claim to be an authority on D spindles, and have never seen one that small, so I was in error in stating that the D series begins with the D1-3. Now then, that said, it could be that the chuck in question re...

Re: Looking for D1-2 chucks for a Pratt a d Whitney 1689

Hey, how about some help here? I read the beginning of this thread when it was posted, and I'm troubled by the D1-2 designation. The D series of spindles starts at D1-3, so I have to assume that it's not a D type attachment, but simply named a D1-2, likely long before the D series of spindles was in...

Re: Mill tooling

How I wish I could answer that one. To be perfectly honest, I don't know that I can put it in words. It's something one acquires over years of practice, and may not mean much when described. It's much like tightening a grade 2 ¼" hex head cap screw. You just seem to know when it's time to stop turni...
