Neal L Posted February 11, 2008 Share Posted February 11, 2008 I have poured my babbitt bearings in the blower I found. Thanks for the help!!! It turns real easy and I think it will last a long time. My next question is what speed should I try to make the blower turn to get enough air for my forge? I plan to put in a slide gate to control the flow and let the blower run at one speed. The blower shaft has a 1 3/4 flat belt drive. I have a motor from a squirrel cage blower that came out of an old heater. It turns 1725 rpm's. I appreciate any suggestions.

jayco Posted February 11, 2008 Share Posted February 11, 2008 I have a blower much like yours that I use an old washing machine motor and a v-belt for power. 1750 rpm motor. I've never really rigged up an adequate air gate on mine.......Mine blows like a leaf blower or 'hurricane' You'll have no problem getting enough air!

brucegodlesky Posted February 11, 2008 Share Posted February 11, 2008 Neal, did you get any pictures of the procedure. I have a similar blower in need of the same treatment. Thanks bruce Quote Link to comment Share on other sites More sharing options...
Neal L Posted February 12, 2008 Author Share Posted February 12, 2008 I didn't take pictures as I went. The side of the blower with the pulley was worn really bad so I removed the old material from that side first. I replaced the shaft with a piece of 5/8 round stock, put the two halves of the blower back together and centered the shaft with a plastic 5/8 bushing and some tape around it to get it up to the sizes of the hole. I used a flat washer with some high temp copper RTV silicon gasket maker to hold it in place and keep the molten babbitt in place. I heated the housing to about 400 degrees the the acy torch. I heated the Babbitt in the ladle on a propane burner to around 650-700 degrees and poured it in until it was full. Oh, I used an infrared gun to measure temperature. I went away until the thing cooled. I had to drive the 5/8 rod out with a brass punch then i used the dremel tool to sand the inside diameter until the shaft fit freely. The I repeated the same process on the other side of the housing. I need to get better at remembering to take pictures i guess. I hope this helps Quote Link to comment Share on other sites More sharing options...
