I don’t know, that seems reasonable.

Nice!
Looks built on an old barbecue grill frame. Portable, so why not!

I might have to copy that.
Thanks for sharing it!

Brian

Yes, definitely from an old gas grill. They're free for the taking around here.

Considering it came with the tank I'm happy, same guy I bought the 2 x 72 grinder from and he gave me another piece that goes with it for contact wheel grinding.

With the forge, belt grinder and heat treat oven it seems I'm getting into knife making....

I’ve a few lathe tools for sale on marketplace and last week someone messaged me via one of my adverts to ask I buy tools/tooling. He’s helping sell off items from a business that’s closing down, so I bought the following for £100 ($115):

I got these from @matthemuppet2

I paid $700 plus $22.50 shipping.

The boring bars are solid carbide. The 3” end mill (which Matt gave me for free) is just a conversation piece.

A lot of the drills & end mills are solid carbide.




He also threw in this round bar for free:



Thanks to Matt!

Received my 2HP 3Phase motor for my 75mm x 2000mm belt grinder build (3" x 72") today. Now I just need to pick a VFD for this use-case and the only materials I think I need to procure are bearings and other random hardware, and an 8" slug of aluminum round bar for the drive pully.

Question. I have a good bit of 5.75" Aluminum round bar, as well as other materials. Any ideas on the possibility of making an 8" drive wheel out of multiple pieces bolted together and then turned to size? I am a bit worried at 3500 RPMs the whell spinning apart. A 8" diameter slug of aluminum is prohibitively pricy.

@Christianstark

Rather than thinking of hogging it out of solid, I would be thinking of welding/brazing shapes together to minimize material removal.
If you don't know of a nearby scrap dealer who also resells, now is a good opportunity to look for one. If you need help with that, start a new thread asking "Any Good Scrap Resellers In/Near Atlanta?".

McMaster sells a 3" long (if you can call 3" 'long) piece of 8" OD x 1" wall 6061-T6511 Tube for $33.
Add end plates with hubs and weld it together. If you don't weld Aluminum, you might also get help with that from a member.

No telling what you might find at scrap dealer so stay open to using steel instead.

You'll certainly have to balance the assembly, but that might be the case if machined from solid. All materials may not be sufficiently homogeneous to be well enough balanced for 3500 RPM.

I scored this (shop made?) air driven tool post grinder off of Ebay for cheap.

My guess: you've got an air bearing spindle (light duty tube with connection at 90° to the spindle?).
The flat on the rear shaft suggests a drive pully should mount there.

The rear shaft goes in an AXA holder.
