I will start sending them email now so when I get to order mine they will have that done at the factory :D

Side comment, I think I saw somewhere that they sold Langmuir to another company??

Yeppers - ShopSabre. I remember their emails, but I never looked into them.

No, it's a cinch nut. Just like a sink drain. A ball valve is most definitely in the plans!


I was planning on the KISS principle involving: Fill bucket with fresh water, transfer to table, use for a day, drain, dump in the gravel. The tray is going to get full of dross and be pretty messy from what I gather, but I have no reason to keep nasty water any longer than I need it. What with the hose nearby and all. I've got a tip on adding borax to the water, but I'm gonna wait and see. Then there's the investment in a bottle concoctions to add to water to make it less like water or something. I reviewed the SDSs on a nitrite base and a propylene glycol plus mystery patented caca in a bottle that looks like antifreeze. Both of these products require monitoring and adjusting pH up to twice a week. At least, when used as directed.


I've been paying attention to them for a number of years, checking in now and again as they grew. I think they diversified and merged or some combination of fancy business things like that a good while back, but they seem to still have kept the company on its presumed track. I'm still pleased with the project. I should go into all projects with low expectations, that way there's nowhere to go but up. I thought I'd get a "cheap" toy, but it's a really solid product. Winning!

Borax does work well, that's all a friend of mine uses. He even has a 5 gal bucket of the green stuff but doesn't want to waste it.

what does it do? Does it keep the water from going rancid ? Keep it clean? since boric acid (from borax) is a flux, it surprises me that it's used in a plasma table

When you press a male center punch into a female center hole, it expands the end of the shaft with the center hole. The amount may be slight, but the harder you push, the more the small end of the taper expands. The smaller Jacobs taper probably had much less meat on the end to resist expansion, hence the higher pressure required.

If there was a big enough hole through the chuck to allow access, a flat-nosed tool in theory should not expand the taper, and the arbor should pop out easier.

I've removed 6JT arbors by pressing, and it wasn't that bad a job. I had to drill a hole in the Jacobs chuck housing for access. One downside is that from then on, small enough drill bits will bottom on the arbor, rather than the chuck body.

Your reply makes good sense and I can offer no contrary evidence.
On an Albrecht chuck, that hole is actually threaded for the screw that actuates the jaw movement.
My attraction to using the center punch was it seemed an appropriately stout size and the point/center engagement would serve to keep the punch away from buggering the female thread in any way.
I suppose I could put together a test procedure to compare center punch vs flat punch, but instead, in the future I'm going to add a piece of brass tube to protect the thread and use a flat nose (pin) punch.
Thanks for the wake-up.

It slows rusting and rancid nastiness. I use sodium nitrite and a little Physan 20 (anti-bacterial) for my cheap concoction. It works great. You want a PH balance >9.0. Borax is cheap and readily available. I've been draining it into a 5 gal bucket with a lid to avoid evaporation, but going to kick it up a notch drain, and auto-refill, likely compressed air. This only becomes an issue with me when I use the table more frequently. I haven't used it in months due to other projects.

Not sure about keeping it from going rancid. It does help keep the parts from rusting and I noticed that all the slop will settle out of the water over the weekend. A box of washing powder is cheap enough to just do a water change if it does turn
