I saw that on a lathe with a 2½" brass bar sticking out about 3½ feet, the lathe was started at about 800 rpm instead of the intended 60 rpm, it lifted a 32" swing lathe off it's floor mounts.

That was a common scam 30-40 years ago, your business would get an invoice for listings in trade directories and such, if A/P wasn't careful, sometimes they slipped through as it looked like it might be legitimate.

I'm not sure what the limit is but I know that there are no import charges/duties on an $89 item, I've gotten more than that without any charges unless shipped by DHL or UPS that charge for making out the paperwork that says it's exempt, if they wait and combine until they get a container full...

'metal injection molding' is called diecasting, at one time I worked for a company that made molds for transmissions among other things. What the guy doing the pistons was doing is called permanent mold casting

If you are using inserts, there are left, right and neutral angle inserts, the left and right angle ones determine where the 'nib' is or if you are parting a tube, where the bur is left. The same can be done with a high speed steel parting blade. It should be noted though that especially with...

Or 10 bearings for $17.89 CDN on Aliexpress if you are willing to wait

The 12.9 bolts aren't just harder, they are 'tougher' as well, they will not be 'brittle'.

Trying to pick an issue like that is hard as just like we don't know how they have gravity on their spaceships, we don't know how they generate their power or if it's even electricity. Like Peter said, "Once we step into the realms of fantasy, we can justify anything..."

You don't have to get very deep into movies for the wrong bird call, the sound EVERYONE uses for the bald eagle is actually the red tail hawk, the bald eagle call is a series of weak chirping whistles, of course that wouldn't fit the image.

Depending on the size of the bearing, you can also shrink the bearing on by heating it in clean hot oil, at least 200°F but not more than 250°F, it would even help to put the spindle in the freeze, the greater the difference in temperature the better. You won't have a lot of time to get it in...

My snowblower is at least 15 years old, and I got it used, it has a smooth surface and the contact wheel have negligible wear, personally, I'd be more concerned with wear from a sandblasted surface though I doubt it will affect Brian's model either way he does it.

If the feed gear set doesn't have one, changing one of the higher speed gears to one with a fabric laminated phenolic, or possibly nylon, should cut down a lot of the noise from that source.

I'm not sure this is the same but it's made in Canada's oil country, the drilling mud and many pond flocculants are made from the same kinds of clay, there is likely a local supplier that would be less expensive if you aren't in Canada. https://pondpro.ca/pond-pro-quikclear-flocculant/

I had a Sajo mill like that, though bigger than yours, they are quite versatile, especially because the Sajo had a longitudinal axis that could be angled for spiral milling and such, having years of experience on turret mills, the thing that would have made it better for me would have been a...

All interesting tools. I've never used one but your 'cross linear knurl' is almost an external equivalent of a valve guide knurl without the spiral, a good solution to an expensive problem.
