How to clean up the shop?.......

Bring home an old friend. ;)

This was the machine tool that started it all... It's an old 17" Rockwell Delta that I bought about 20 years ago. It has a mt2 taper in the quill, but with the 1750 rpm motor it was just too fast for metal work. I have since picked up a 3 phase 1140 rpm motor and a vfd for it and I think I am going to be happy with it again.
In order to fit it in I had to move the old tool and cutter grinder to the back of the shop, which in turn required locating the floor again.... After a few hours I managed to find it. :rolleyes:
 
Inline 6 headers, hmm interesting... best guess:
4.2l AMC/Jeep?,
50's Ford 223?
60's Ford 250 <-- I think most likely this one

Please tells us more?

That 89 six cylinder was a beast and IMHO the best engine those Jeeps ever had.

Once I ditched the factory carburetor and ignition it perked right up and has been very reliable, it is a little bit cold blooded though now that the intake manifold isn't heated, but once it is warmed up it smooths right out....
 
Okay, here is the challenge, we want a video of the jeep launching itself off a good size bump, doing a 180 and landing in the adjacent river tires up. With a this side up sticker on the door panel.

While the lathe was merrily facing some parts for some levelling feet I have planned for the 13" lathe, I took the opportunity to mount the vfd to the side of the drill press. Next is to make an adapter plate to mount the motor, then to decide how to best transfer the power from the motor to the quill. The motor shaft is bigger on the new motor, and the pulley doesn't have enough meat in its bore for enlargement. I am contemplating just going with a single step pulley. The other option is to take the motor apart and turn down the end of the shaft and put in a new keyway.....
Any suggestions?

I know lots of guys turn down the motor shaft, but it's not something I'd do.

Is that drive pulley just shy of meat at the small end? If so, you could just lose that groove and use the VFD to compensate for it at the high speed end.

That's what I did on my mill for different reasons. In my case, the shaft was too short. I didn't have to cut my small end off either cuz there was room for it under the mounting flange adapter.

If you still don't have enough meat after chopping off the small pulley, you can either make a new pulley that does, or buy one. If your new motor is VFD Rated, you only need one pulley groove anyway.
 
The pulley is shy of meat over its whole length, so snipping off the small step won't help. I am not sure if this motor is vfd rated or not, it claims to be made by Rockwell Delta, but I suspect that it's a baldor out of the early eighties. I will have to dig around and see if I have anymore step pulleys kicking around, I think I might have a spare here. This is going to be my first dive down the vfd rabbit hole.......
