20" Jet Drill Press Table

[wierdscience]

Check the old one with a file and see how hard or not it is, then plan from there. If it's a soft shaft, stress proof is excellent material to use. If...

I would use the angle plate in the mill method. Also, from having done a few, it's a MC, not a Swiss clock. If it's out of parallel a couple thou, it's...

Good buy, locally the last mill that sold on CL with it's mostly complete tooling package went for $40 less than new and it's didn't have the rotary ...

That's a common method for heat treating steel using stainless tool wrap. The paper consumes the last bit of oxygen in the pouch to reduce or eliminate...

Yep, you're right, that cancer spreads back to the primordial ooze of homeshop/light commercial drill presses....

That's the J-2550 which is a 1/2 HP less, has a smaller chuck, but costs $200 more, go figure....

Ordered in a 20" Jet Drill press for a customer this week. Nothing to write home about, typical China, runs okay, decent power, decent runout, sharp...

My money is on the contactor not making contact on one or more legs.

I got a good bit of 3-4" thick Aluminum blocks laying around, that should suffice....

7.5 kw aka 10hp is a bit much for a 1/8 end mill doncha think? ...

I'm leaning more towards the ER25 model, the speed range I need is 10-12k and I'm only talking 3/32 and 1/8 carbide endmills. Mounting will be a clamp...

[wierdscience]

Yes on all counts. I've seen those little motors with the collet chuck stabbed on, they really are toys. They could have improved the attempt by shrink...

[wierdscience]

Ya, watched that, hate to think what one of those spindles costs. I'm guessing $3k?...

[wierdscience]

I think I may go for the ER25 model now that I think about it. It would make better sense, since I already have two sets of ER25 collets....

[wierdscience]

Thanks for that....

[wierdscience]

Yes, there is another link to a 120v 400hz inverter to run them....

Good grief, that looks like a class action product liability suit in the making.

I see where the cordless tool market is going to higher...

Well it is, just the B-port table feed is a bit of a pain to take off the leadscrew unlike a Servo or servo clone. That, and I slip the gib out instead...

What about the two arseholes driving the lifts? The one that tried to squeeze through and the other that had his lift parked in the middle of the isl...
