Well today I got it apart and got everything cleaned up..

I believe the blower had been messed with... There are some things that don't make sense to me.. The middle shaft slides through and is not locked to anything.. In other words there is nothing to hold the shaft in the blower as both ends are open.. So, I'd have to guess that the shaft had been replaced..

So the end shaft play isn't regulated.. I believe there is suppose to be either a washer attached to made on the shaft or the end cap was drilled out..


the bearings for the output shaft are complete toast.. Some were missing and the ball cage only had half..

Only the area right under the gear has a bearing on it.. The rest of the shaft is only supported by the cast iron it runs through..

In some ways it seems like it was engineered backwards.. Or I should say using older technology to build and design it..

The 12" uses bearings at both sides of the shaft.. I believe they did away with the outside bearing to stabilize the shaft using the cast iron as the bushing.. Hard to make assumptions 115 years later..

So I have included pictures of the middle shaft which controls lash and mesh between the top gear and the bottom pinion..

You turn the eccentrics and lock them in place when you find smooth, quite, running..

You can see where the tapered pin half was left when the fool drilled out the hole and threaded it for the bolt.. Still makes me made.. The tapered pin came right out..

Here you can see the fan size differences.. The 16" is a lot larger..

The lower bearing is toast.. It will need replacement.. It was a cone which is attached just below the pinion gear.. Then the bearing cage, which 1/2 is missing and some balls.. The inner race and the cone are shot..

Also, the Champion forge and blower company with the famous 400 blower later you can see that Buffalo offered the same model but with Buffalo's name on it..

The silent 200 was a Buffalo forge and blower only offering..

If's pretty amazing to me still to think the golden age of the blacksmith was really short lived after WW1 blacksmithing as a trade started to fade and by the depression most were gone..

Mind you there were ones that lingered.. I knew a guy who ran his shop into the 60's and I imagine it was the same in a lot of mill towns.. I know there was an Axe company in ME who also lasted into the 60's making hand made axes..

I was able to get a lot of the loose fitting problems addressed between yesterday and today..

I tried to use al-Br tig rod and tigged it on for one application.. My results were varied and not at all happy with the finished product.. I ended up with lots of mixing of the cast with the bronze.. I put some all around the gear that fits into the other gear and filled the screw lock area with the bronze as well..

I then turned both parts to smooth out any wear and then gave them a slip fit..

I then threaded the hole back to 1/4X20 tpi and put a lock screw in..

I also fixed the buggered threaded hole the idiot did.. I A/O brazed all that back into good shape after trying the tig rod last night again not happy with the results..

So after I laid and filled all the holes I had the forge going so just laid it on top of the fire while I did a road trip..

Came back to a nice straight and true cast iron gear with no extra broken bits..

I'll need to find a tapered drill bit so I can reproduce what was there..

My plan is/was to make the blower usable and once the shop is up I'll cut new gears once I get the new equipment in.

Heres the pictures..

Now I just need to figure out how to get the old bearing out of the blower housing..

Any idea's? There are no lips or cut outs inside the housing for bearing removal..

The bearing is smaller than the casting boss..

Can you make some sort of expandable puller? Turn something in the lathe that will fit into the bearing race and slot it so you can thread a tapered bolt in and it will expand into the race and allow you to grip the race to pull it? Do you have access to both sides? If you can get the puller to expand, you might be able to hit it out from the backside instead of pulling it.

Or try welding something to the race to pull it out. I think I remember someone welding a rod or something to races before and the welding would help shrink the race loosening it after it cooled.

Run a weld bead around the inside of the race to shrink it and it should come right out.
