Thanks so much to everyone who posts these codes!

I would recommend taking the money you are going to spend on carbide end mills and just buy good quality, sharp, HSS taps instead! :wink: It just seems counter productive to use cheap carbon steel taps and then plan to spend time and money to try to remove them when they break. While your advice ab...

I just use center cutting carbide end mills . No worries about over heating ,in fact hotter is better . I've spent a couple of evenings looking at carbide end mills and drills, and I'm confused. There are a number of kinds of carbide. I found an old post here saying taps are generally hardened to 6...

If I was a professional in construction and using them every day, crawling around attics, crawl spaces, roofs, and on ladders, cordless would make sense but for a hobbyist like myself, I'll have nothing to do with them. <snip> Pete What he said. All my battery-powered tools hit the trash can over a...

I did a search and didn't see this trick posted, so maybe it will help someone else out some day. I broke yet another carbon steel tap today. I was using it because either the shanks of the HSS taps I'd have preferred were larger than the thread OD and would not fit through a reamed hole outside the...

A 9X20 would be better but as Steve 12X36 is a very useable size. Down size is as it gets bigger the price follows big time. I looked online at a 9 x20 and 12 x 36 and they are both out of my budget by far. :( So...both were (I think) good deals, but: Very well-cared for and not very worn 10" ...

Depends on what kind of work you want to do. If you are into model making, a 7x12 may be all you need, but if you want to build a large scale steam locomotive, you will need something bigger and heavier. The price will go way up. All I want to do is start tinkering with aluminum stock, small projec...

Assuming a conventional compound slide T-slot, an AXA-style toolpost should fit a 10" lathe. Virtually all of them need to have the T-nut cut to fit your lathe's T-slot. There might be someone on the board willing to help you out; knowing approximately where you are would help.

Large print. Which makes it legible. On a good day.

Sounds high to me unless a lot of threads are engaged. As a reference point, spark plug torque into Al is 18.0-21.6 foot pounds according to NGK.

I got it a few months ago, and it's fine. No bleed-through, perfectly legible. I've been paging through it from start to finish, stopping once in a while to read a section, and I'm in the pp.1800-1900 part of it now (reading about the 3-wire method of thread measurement). I presume the rest is also ...

Rule of thumb is to always have at least two teeth in the cut. Fewer tends to shuck the teeth, while too many offer the chance that the blade will load with chips before exiting the cut, slowing down the cutting action and dulling the blade prematurely. Armed with that idea, it's always a good idea...
