Checking tail stock alignment.
Stick a piece of material larger than the tailstock quill in the chuck and turn it down till it's exactly the same diameter as the quill. Run the tailstock up to the the turned stock and then run a dial indicator along the top of the quill and onto the part in the chuck. Do this with the quill...- LKeithR

Magnetic v block steel and laminated brass 4 1/4 x 3 1/4 x 2 1/2 vintage (only 1 though) for sale
You talking about me? I thought it was a legit question. I think the term "vintage" gets used way too much these days and I sure don't buy the idea that something 20 years old is vintage. Fifty years maybe? But not 20...- LKeithR

Moved lathe and now have taper.
Yes. A lathe is a precision tool that needs to be adjusted each time it is moved. You had it dialed in so you know what it's capable of but once you move it you must re-align it. Start by getting it as level as possible (with a precision level--a laser level is no where near to being accurate... -

M24 threads with a Mag drill?
I've got the same beast. I've tapped smaller holes with it OK but M24 is getting up there in size. Biggest problem would be just holding the tap without it spinning. Not gonna do that with a regular drill chuck. If the parts have to go back to the fab shop how are "they" going to tap he... -

9" rear end model/drawings
We've made lots of custom parts for cars over the years and when we needed dimensions we just grabbed the part (or parts) and reverse engineered it. It's not rocket science. If you need the dimension from the centreline of the axles to the carrier face just machine up a piece of stock that... -

Standard Keyway Practice
Ha! I've been vindicated. I've always cut keyseats in shafts using three passes (one down the middle about .015 short of full depth and then one down each side to finish). Always thought I was being overly fussy, especially when all the Youtube videos of guys doing it in one pass started... -

Diacro Manual #3 bender
What holes specifically? As far as I know you can go to the Diacro site and download a manual for that machine. Would be the first place I'd start. We've got a #3 but it's in storage right now. I guess if you were stuck I could arrange to dig it out and take some measurements... -

Will steel DOM fit over shafting?
I've used quite a bit of DOM over the years and I'd have to say that when you're talking size for size it's not going to fit, at least not consistently. For a one off project you can measure your material and find parts that will fit together but if you're talking a production situation I... -

trouble cutting a 8 TPI thread in SS304 - engine lathe
I've used "Top Notch" style threading and grooving inserts for years and I don't remember ever having a problem like that. Haven't done a ton of SS but I've done some and if there's a problem it's usually the material itself. Can you grab a piece of "known" material and see how it works... -

Alternative "No Math Required" solution for duplicating simple bolt cirles
What's wrong with using coordinates to lay out the pattern? Machinery's Handbook has tables with coordinates for a large number of bolt circles. There's a bit of math, you have to multiply the coordinate by the circle diameter but that's pretty easy. I do it all the time. In the time it took... -

WTB ~13" Lathe and manual Mill for small Business
For sure, but two to three times the price. As for a lathe, in that size range I would look for a 14 x 42 rather than a 13 x 42. I think you'll find that the 14" machines are more common and you'll be surprised how often that extra inch will come in handy (says the guy who bought a 13" instead...- LKeithR
