That sounds easier... What kind of bit?... Is there some kind of super tough metal routing bit?... (This stuff is very hard)...

Go to a machine shop supply house & toss it on the counter & ask them what kinda tool would ya need in your drill press to do it. Ask if they know of a machine shop owned by a biker type,, sometimes people cut people some slack,, I had a guy drill something for me, took about 1/2 hour to set up & do it, cost me ten whole bucks,, & he had a bridgeport & that thing was struggling,, I had no idea that metal was so hard.

A drill press isn't going to help with this. This needs to be done in a mill or a lathe. Without removing those side-plates, I would do this in a mill but seeing as you already ground away the only two surfaces I could have located against, I would have to do this in a lathe. This means the side plates have to come off and then attempt to reinstall the plates afterwards. The unfortunate thing is, unless you're friends with a machinist, this isn't going to be cheap.

*edit* Looking at it again, I think I would use a mill. I think those side plates are straight enough to locate on. It would definitely be a LOT easier.

If,.....as was said, the metal is too hard to cut w/ carbide, it must be ground w/ a very hi speed grinder !!

Maybe the drill press idea isn't that far off, but it better be a super hi speed drill press, and even then the stone speed at and near the center is very slow.

I have the lathe, and I have a very good die grinder, but I have never thought of making a tool post holder for the grinder,......maybe a good rainy day project !

JOG has the best idea !

Hey guys,.. I've been out in the shop doing deep thoughts and some measurements...

I think the consensus is correct... the inner surface needs to be trued on a lathe...
I am surprised that the pulley can be cocked on the shaft, but that appears to be it...
So,.. recommend if you try it... you need access to a lathe...

I'm going to sit on this project for while and see if a lathe turns up in my sphere of influence...

While you are better off finding a good used US made quality lathe, (good luck) don't underestimate what a China made HF lathe will do.
The price is right, and they are cheaply made, but if you don't get in a hurry and "horse it" like you can a good lathe, it will serve the purpose for most projects just fine. I know I use mine far more than I ever expected, and in 8 yrs the only serious thing was I smoked the motor, not hard to do on any china stuff. Embarrassed

Alrighty,... how about a high-speed router with a grinder stone bit and a flat plate with a hole in the middle mounted against the pulley for level...

That stuff,... I got... (if the bit can go that deep)...

PS..Routy,... isn't there some way to use my Raptor to fix this?... Grin

...

PSS... OHH! Neighborhood wide yard sale today! No telling what tools I might find..

+1 I got one of those Grizzlys and it's not too bad. It had a minor oil leak and I had to send back one of the castings for replacement, but it has settled down into a pretty good groove now.. they just take some finessing.

Back to the problem at hand.. yep I think the drill press w/grinding stone on a spindle is the best idea. Well, second best, the best being to show up at a machine shop with a 6-pack at about beer thirty..

That'd be hilarious if you chucked up the pulley in a lathe and clamped a raptor petcock in the bit holder, take a picture of that as if you were about to use the petcock as a machining tool. "SEE Routy?? The raptor CAN fix everything!!" Grin
