Topic tags/keywords: question bandsaw refurbishing

I bought a 36” S A Woods. Bandsaw. I think the shafts have too much play in them but I’m not familiar with a machine this old. I’ve seen articles in woodworking magazines before but I thought this may be a better place to start. Any help is appreciated. Jeff

OWWM (sorry, now had an excellent series on how to repour Babbitt bearings. Unfortunately, the wiki seems to be down right now. As I recall, they even had a complete video on DVD that covered the process from one of the ArnFests when they poured Babbitt bearings for several machines.

Here's another source. There are many more on the Web. Google is your friend.

Although I don’t have any machines that have Babbitt bearings, this is a fascinating process to me. I hope you’ll post details of the process if you do this.

Thanks for the site. I would love to do these myself if needed I hoped someone would have experience and know when they need replacing also.

Repouring babbits is not difficult in process but you’ll probably have to do the first one a couple times before you get it right. You have to get familiar with all the tempratures & etc. is the place to alk to experts about this.

Thanks again. These are the times when I miss my grandfather, he was a machinist and Jack of all trades.

You may have shims under the bearing cap that can be removed to take up play as the bearing wears.

I have a round casting housing round about 3-3/8 diam and 7 inch long and shaft spindle to fit the same

I need to pure a babbitt bearing here NO cap I would like to just pour this bearing? From the top through the oil

holes there around the shaft.

Can I remove the shaft after the pour???? I would like to just hit it with a mallet remove it.

Can I remove it after the pure???? Will it shrink and hold the shaft in?

Could use all the help I could get.
Thanking you in advance

I’m not sure. If you smoke the shaft it won’t stick. If it will slide out I couldn’t say for sure. But if you heat that closed housing and pour Babbitt make sure it doesn’t sweat. Be completely dry or it WILL SPATTER. Check my blogs someone gave me a link that helped alot to the old woodworking machines

I have poured a lot of bullets. 500 gr .45 will come out +/- .5 gr or better with a 400 degree mold and 775 degree lead. I don’t know if you want to preheat the housing that hot, I really doubt it, but I am sure preheating will be of benefit. Smoking the shaft or getting some mold release from someone like will do it too. Best thing to flux you lead with is beeswax or paraffin. Just light it and burn the smoke off when it starts to smoke. Do not use commercial flux agents. some of them will rust everything with 1/4 mile ;-((

If you use wheel weights for a lead base, put them in chlorine. If they bubble, do not use them. They contain zinc. Many of them do since they started making the the stick ons.
