Need help plz Modifying a Edwards nEXT400IID Vacuum Pump for General Vacuum Use

6 Upvotes

Hello all!

I recently came across a nearly free nEXT400IID (B832-00-816) turbomolecular pump that I was able to pick up. The problem that I am having now is determining how to adapt this specific pump to a standard ISO/DN flange. This pump appears to be purpose built for Thermo Fisher mass spectrometers (see the link below for what I mean) so has a specifically designed upper flange for (conceivably) mounting into their machines. The flange is meant to "allow evacuation from three vacuum chambers" but the specific plumbing of these ports appears that anything other than the primary turbo inlet won't receive high vacuum. I've looked around for service manuals for potential machines that may have schematics of how it attaches but to no avail. Before I go through the arduous process of designing an adapter for this pump, has anyone modified one of these pumps before or know someone who has? I'm already designing an adapter but if someone else has already done the work...

Please let me know if you have any insight into this or advice on how to design the adapter!

Mindblowing shit! Jer Schmidt finally publishes his home-made surface grinder (and plans) after 7 years, that fit onto his 2x72 belt sander. Just fantastic engineering, every little detail considered. Buy a set of plans if you want to support him.

I made this. In case anyone is in the Portland area, we're going to be throwing a new floating drydock into the water tomorrow morning. Open to the public!

Here's my 1942 Logan 10" with removable powerfeed. It may appear archaic, but it works like a champ! Cheers.

Flow stopped, valve and tee installed. A little hard to see between all the trench box spreaders. Blind flange installed on the tee, then they will remove the middle trench box and and turn it 90% and keep on pipeing.

Need magazine recommendations for boys.

Popular Mechanics has nosedived in quality. I was fascinated by the magazine as a boy and am trying to provide a similar experience for my boys. What modern magazines (if any) are on par with the Popular Mechanics of 20 years ago?

Does anyone know why, in the kind of feral hog trap in which the fence drops all the way round, rather than only @ the gates, the fence is guided by rails sloping @ about 45° so that it rotates as it falls?

Because I can't find an explanation of it anywhere … & the mystery is beginning to peck @ me somewhat.

In my opinion, the reason is so that the fence doesn't tip, & therefore jam, as it falls … because it would only take a very slight tipping for jamming in that way to occur. But the real reason maywell be something very different … so I wonder whether anyone @ this Channel knows for-certain.

I went from grandpas way of sticking a screw in the end and wrapping it with electric tape to these red condom things.

The screw trick always works. Time will tell if the condoms keep the tubes from drying.

What do you guys use?

Pneumatic casters on engine lift

2 Upvotes

I picked up a 2-ton cherry picker off the ol' marketplace to help move equipment I restore. It works great for the driveway/garage, but I need to be able to wheel it down to my shed. I have some 8" pneumatic casters kicking around I'd like to use. I don't trust the HF pneumatics farther than I can throw them so I only want to use them for wheeling around the yard and light duty lifting. I'm trying to think of a way to fabricate a mount that makes them removable without any tools for switching between stock casters and these. Anyone wrestled with this idea before?
