OT: 500 megawatt compressed air power storage
Apart from Cyanide, this thread went to utter shit faster than most except for the Covid related ones. Mods, a mercy killing is in order...- Milland

Foundations of Mechanical Accuracy by Wayne R. Moore
Hi Rich, Thanks for the "promotion", but I worked at MIT, didn't graduate from there. Alex is someone I know, I can't quite claim him as a friend, but an acquaintance. He is a friend of Josh's, the guy who owns the company you did the Somerville, MA training in some years ago.- Milland

How to Measure and Model a Curved Gear Rack
I'd not use steel, how about Delrin? Steel may just mangle the mating part, and the extra weight may throw off the "pedal action". -

Starting a dead tool grinder
Contact the manufacturer in VA? I'd hope they'd be cooperative, given it's a training institute.- Milland

Looking for 7" dia thick wall steel tube for bearing housing
Huh - doesn't seem like 1" wall there. Is what you're making going to mate to that, or replace it? -

How to Measure and Model a Curved Gear Rack
That's just molded plastic, so likely not super-precise. I'd be tempted to scan it, then import the scan and fiddle with it in CAD to mock up the profile. What's the part do? What sort of loads and speeds? -

Getting a mirror finish in aluminum surfacing
You should check into post-milling diamond burnishing. Single crystal ball tip, filtered coolant, and just rub that baby smooth... https://www.google.com/search?client=firefox-b-1-d&q=diamond+burnishing- Milland

Machining Renshape 5060.
Think about dust collection and coolant/oil contamination if you have to keep the material clean. Some spindles spit a bit of oil out in normal use and that could be an issue in bonding cut shapes.- Milland

Odd Preciptate and Scarring during Titanium Anodization
DamnifIknow. Any chance you're dealing with shoddy Ti that's processed poorly? Do you have samples from known alternate batches you can play with? -

Looking for 7" dia thick wall steel tube for bearing housing
I agree, but it's already a lost cause with the buyer doing post-machining welding on this housing. It's now a matter of doing one's best, then if needed trying to bail the customer out after the fact with a sleeve and rebore. Sucks, but the guy with the money is always right. Right? -

Odd Preciptate and Scarring during Titanium Anodization
Have you tried electropolishing the Ti before the rest of the process? If there's contamination that the etchant didn't remove, perhaps the EP first step will help. -

Cleaning windows on a Haas VF3
Haas windows scratch easily, so cleaning may not do a lot for you. If you want something safe, a clean, fresh mixture of your coolant and some rags may work (although you want to hose down any stuck chips first), or you can use the cleaners meant for computer monitors, those should be safe.- Milland

How to Spend $43k on CNC Mill & Lathe Tooling
A spindle speeder for the mill can be a help if you wind up with the need for small cutters, but many are not great for stiffness, so use with care. Pricing could go from ~$1K for the air fed, to $10+K for the fancy pants types. You can get them for the lathe too.- Milland
