(3) IF the bearings were junk and/or seized or races overheated (blue), THEN I would worry about replacing them. They would probably have tapped right out with a taper drift working around the outside of the visible lip (in the video).

Unfortunately, you created a headache for yourself by not "seeing" the edges of the races or "hearing" what the smart people here told you to do (or not do)... I can't tell if you welded the race to the spacer or shoulder of the pulley!

When I saw the races in the pulley bore, this is the tool that immediately sprang to mind. That and a hammer...

I would have packed them with grease and run them,if they got hot after a days running imay have changed them,probably not...

This sawmill reminds me of a guy i knew that was going to build geodesic homes out of 6'' foam.
To do this he needed to cut the foam so he built a big steel building to set up a foam cutting machine in (that he was going to build).
After the foam was cut he would build the building and then spray gunnite? over the foam.
So he buys some old worn out concrete pumping equipment and he was going to rebulid it all.
It was all covered with concrete,so he buys a sandblasting business so he could sand blast the concrete equipment.
Buying sand in bags was too costly so he bought an old fuel tank that was about 8' diameter and 20' long and built a trailer under the tank and put hatches in the top and end of the trailer so he could haul sand from the mine,about 25 miles from his shop.

He was going to tow that tank full of sand with an old plymouth wagon.
He never considered the old wagon would never stop a trailer full of sand.

What the ending looked like was a yard full of rusty junk,with piles of sand all over,a new steel building full of white foam and a home made cutting machine that used an element out of a house oven as a heated wire to do the cutting.
A pile of rusty gunnite machines and a slab he had poured for the dome house which never got built.

The auction was a bust pretty much ,after the old man died.
The only thing he needed to complete the cluster fuck was a sawmill.

"The only thing needed" Bwahha ha
The wheels run at what...20 rpm? A brass bushing will do.

You guys never mentioned welding in the center of the race, must be your fault.
I've usually done it by heating an inch of the race red hot and letting it cool. Works well on brass bushings too.

This was post #6 on this thread. I saw this coming

LMAO...

Gerry please remember logic and experience are not allowed in Timmy's threads.

I think it was mentioned a few times... But Timmy don't read too good.

But he was still thinking it was a single piece, not 2 races...

Going to have to anneal the other side to be able to machine it. Or use a die grinder to remove the weld and then try boring out the race just like I did with the other side.

Your logic is confusing me. If you have a tool bit that will cut bearing material, why do you need to remove the weld with a die grinder? It should be much softer than the race.

Have you tried the punch idea yet? Or a chisel on the weld itself? Or welding a bung in the race?

On edit, my thoughts are that you are going to remove the races by machining because you have tooling and a lathe and that is what you think a machinist would do. With that thought in mind, I seriously recommend talking to Keith at Vintage Machinery and see what his thoughts are. My guess would be somewhere along the path(s) we have already suggested. Easiest is bestest in most cases, but what do I know.

You should look at the picture. He welded the race to the pulley...
BRB checking on my popcorn.

Actually I think I have it all figured out.

Tim will now figure he will need a cylindrical grinder to redo this part. He’ll spend 3-5000 to buy one and tool it up.

Next will be a heat treat furnace, another 10-20k, to anneal the bearing race.

At that point he’ll need to upgrade the power to the shop with three phase, let’s say another 60-100k.

So for 75-125k, he’ll be able to rebuild a sawmill worth scrap prices at best, to cut 20-30 logs off his property, to save buying 2K in lumber.

You know, in some ways he actually sounds like more of us here than we realize.
