I finally got the 745 in the garage.
I am in the process of tearing it down and cleaning.
One thing I found is that the head will not rotate to the left or right .
I loosened the screws and turned the bolt and it just spins.
It looks like they put a light coat of bondo or something to cover blemishes on the castings. My question is
is this bondo or something else? Should I pull the rivets and remove the nameplates prior to painting?

There is a worm gear inside the mechanism that is probably has some teeth strripped off of, which is not allowing the head to rotate. I would suggest removing the motor and whatever else you can and grab ahold of the head with a engine hoist or a overhead hoist and carefully remove.
The bondo looking stuff is a filler that W-I used for smoothing out the castings before painting. Have no clue what kind of material it is. Sand lightly and paint. I painted my mill with ford blue from the tractor supply over ten years ago and it is doing fine so far. Just hard to keep the mill clean from usage. I highly recommend using Rustoleum brand of paint which does not necessary require primer and use. I've used it with their primer and without, with great results. If you can remove the name plates without damaging them, do so. Most of the time, I cover them with painters tape and it does fine.

Yes, Rustoleum is ok, I've found it chips badly until it dries for a month or two, then it slowly gets harder and more resistant to dings and wear. Much better to find a polyurethane or maybe one part epoxy if you want a hard, chip resistant surface.

I took the inspection plates off my old Dalton Lathe when I repainted it (rustoleum). Then got some brass rivets to reinstall them. Used brass split rivets to put plates back on the thin gear covers on the end of the headstock. You can spread the back end of a split rivet with your fingers - so no banging on thin cast iron parts!

You were right the cavity was full of shavings and someone must have tried to turn it without IMG_1697.JPG IMG_1698.JPG IMG_1699.JPG loosing the the bolts

If you don't support the head as you are tilting, it can catch and strip the teeth. And I agree, they probably didn't have the bolts loosen enough either. I try not to tilt the head. I have a all angle vise that comes in handy when I need to cut some sort of angle. Now, I do nod the head once in a while and haven't had a problem with this. Of course, I haven't taken it past 30 degrees either. I believe the gear is replaceable. I haven't tried to remove it on my mill. And I'm sure W-I stocks that gear, too at not too bad of an price.

When you go back together, I suggest to use Lubriplate 105 grease or equivalent. Please don't use EP-1 or 2 grease in the head. That stuff just cakes up and does nothing for you as you see in the pictures. If it was my mill, Some of those areas I would use just good o oil for lubrication.

The gear that is stripped is one piece and holds the head

Might inquire, they may make a gear to replace that one with a little rework. If not, find one to a Bridgeport and see if it will work. Still have to cut off the existing one to replace. Just a thought. As far as that goes, make one!

Kieth Rucker has a video on YouTube where he replaced the worm gear on his W-I mill. I think his is a Model 845 though.

I was talking to some folks on shop floor talk and they think that the teeth could be welded up and ground down to the correct profile

Thank you after watching that video I can see that it is not a single piece Wells may have a replacement gear

Another option might be to rotate the gear 180 degrees to get the damaged section to a spot where it will never be engaged.

That's what I did. I emailed Wells Index and the gear is available for 230.00

Ouch! Not as expensive as I've seen with other gears and stuff from other "old" machinery companies.
Might not get to eat lunch for a month to pay for the gear. Just a though on funding.

I have ordered some grease and some bearings for the 745. I hope they get here soon before I forget how it goes back together

Well I got my bearings and they sent one of them wrong.
It was supposed to be sealed on both sides and is only sealed on one.

Can some one tell me if all 3 of these bearings are the same?
I didn't take enough pictures and I am stuck
