I wouldn't justify passing on it because of a small amount of work that only comes a couple times a year. I would send that little bit of work out to a sub and get the machine you will enjoy using...

There may be, but why not just write them yourself? If it's to be training type material to be used for your employees, that is probably the best bet anyway. That's pretty basic stuff.

Yes, it was already mentioned. It involves putting a vibrometer or something similar on the spindle and tapping the spindle with a glorified hammer (to simplify it) and checking each individual piece...

First place I'd look is Supergrit website. If they don't stock it on the shelf, I'm sure they can get what you're looking for, and they have decent prices.

As far as using hammers on a bearing and whether or not one should be worried about it if it's a rubber mallet - there are differing degrees of rubber mallet hardness and better safe than sorry IMO....

Totally opened yourself up to a "Yer momma told me" on that one. :D

Jayzus. Manual lathe makers are dying out? You don't say. Never would have guessed. It's only been happening for the last 30 or 40 years. :D

Probably because they stopped making them in the '60's. The Compacs from the same time period that they were rebranded from probably can no longer be repaired either.

The solder blob anecdote may...

I had a quick glance earlier and was mistakenly thinking that you were going to be pressing on the face where the rollers ran when I recommended aluminum or brass. Now that I've reread and looked at...

BesTest are pretty damn good indicators too. I'd say on par with Federal. At least the old ones... Not sure how the modern stuff is, mine are all old. Compac, Interapid, Alina, Tesa, Mahr, all are...

I'm assuming they want a tool used that just slips into the bore by a couple thousandths but catches on the lip once it's in there. I'd use a little heat if you can but don't worry about the freezer....

Ouch! Well I can say if I would have seen that one, we may have been in competition. But it wasn't me! I swear! :)

Anyway, at this point I think I have over 50 QC30 holders, so I will probably not...

An audible edge finder IS a regular edge finder... With a flat ground on the touch-off diameter.

I like the lever, it's good for slipping the clutch when you need a very slow speed, say using a large HSS cutter to cut spotfaces, etc. Also for jogging the spindle around while indexing inserts in...

Where is the confusion? A plated wheel is done once the layer of grit dulls and you can't dress it. Once it wears out you'll need to get it stripped and replated or get a new one. A resin bonded...

Induction hardening will be fine. Flame hardening will also work. Both will probably cause deformation. Straighten the bar afterward if necessary. Many hardening shops can do this if you can't.

I Seem To Remember (or Recall).

I ran G&L boring mills for a LOT of years. Most had the aux spindle. They were older machines and the main spindle only had about 375 RPM. The aux spindle was there mainly for drilling at smaller...

Nope, you don't! I didn't get 'em at auction. They weren't even advertised, sort of fell into them. :)

Yep, you can. I have a Wells Index with a QC30 spindle. I run a power drawbar also and NMTB30 holders work just fine.

And if you keep your eyes peeled you might find that it's not so expensive to...

The only shortcoming other than the setscrews is that the ground finishes in the dovetail aren't real great. The Aloris holders have good flat surfaces and all the same good finish. Looks like they...

He might be able to get it, with a lot of flipping and shimming if necessary. It will depend on the individual piece of material. If it's mission critical just get it stress relieved before grinding....

Cheap import holders are okay with an Aloris post as long as you replace the setscrews made of shite. Still prefer used Aloris off eBay though.

One of the places I worked cut out trenches in the floor and laid conduit with wire already inside, connected at the ends to a piece of copper about 1" diameter with a ½" or so threaded hole. Filled...

That repeatability spec was specifically for the shot-pin 15° indexing as I read it. The actual indexing mechanism that RJ patented should be able to do a lot better than that I think. He mentioned...
