Re: Road Trip to DTI!

AT THIS TIME, my sole uses for it are precision alignments and setting up my new rotary table. Hello Bill, Had to go back to the beginning and read it again as I forgot what the actual question was! Anyway, my first DTI was the very same one as yours. After years of good service attached to a small...

Drop the knee about two inches, then chase it with the quill, and then see if you are still within .0001" you guys that have taken the notion of using a tenths indicator as meaning one expects to work to tenths are offside imo. Mcguyver, Sorry if my post was unclear. It was written with the pretens...

Next time you center to .0001" on your milll........ Drop the knee about two inches, then chase it with the quill, and then see if you are still within .0001" :D Or just move the quill a couple of inches and check it again. I'll agree it's good practice to get familiar with using DTI's, but the real...

Look on the Enco, MSC etc. sites for corner rounding end mills. You can get them individually or in sets. They come in various sizes.

Bill, Assuming you're not centering over large bores, you mostly do smaller work, and you just installed a Z scale on your mill: If you really need to center to .0001" do yourself a favor and use a Coax Indicator first and then follow up with your new B&S. As Jose stated, you'll drive yourself nuts ...

Bill, I have a large (7' tall) Roll-In vertical saw and it uses steel blocks for blade guides with rollers for rear edge support. They are four sided and you rotate them to correspond with blade width as the saw will accept 1/4" to 3/4" width blades. I bought the saw in 1980 and threre is no visible...

I certainly don't want to spend a few hundred bucks on tools I can't use properly. Good Morning Dave, That's one of the benefits of negative tooling......it's relatively cheap if you stick with common holders and inserts such as CNMG or TNMG. TNMG being triangular with six cutting tips and CNMG wit...

Hello Mike, OK, so now I'm confused!!!! You ranted about not having the Carbide insert or tooling you needed, made it sound like indexible tooling is the worst most inconvenient thing ever created because you didn't have what you needed, but then you go on to say how wonderful and convenient HSS is....

Hello, Looking at one of the images above, you seem to be hung out there quite a bit. The part is only being held with about 25% of the jaw and the cut looks to be a couple of inches out from the chuck. I would suggest keeping the cut as close to the jaws as possible for rigidity. Not as likely to d...

Wizard, Perhaps knowing what diameter plugs, and what material they were made from would net some answers. I'll stick my neck out here and assume you meant 150°-200°F. You may have retention problems other than those little plugs at 150°-200° C :shock: A magician couldn't keep one running at those t...

I read that the thread is 1.25" x 20 tpi. Where can I find the diameter data for that? Assuming it will be internal threads..... A good starting point might be a: Minor Dia of 1.201 (65% threads) Major dia of 1.255 Compound movement of around .032" at 29.5° should get you close. Too many variables ...
