Joel OF Posted March 2, 2013 Share Posted March 2, 2013 A little while ago I bought an Alcosa F20 hand cranked blower that's meant to bolt flat onto a side blast forge. As I have bottom blast forge I want to make a stand for the blower and hook it up to the existing pipework under my forge with some flexible pipe. As the blower is quite heavy I was thinking of rotating it through 90 degrees, (meaning the air would be directed straight down), so there's no shear weight from the blower on the bolts/stand which would mean the stand is much easier to make. Is there any reason not to do this? Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted March 2, 2013 Share Posted March 2, 2013 Oil ressivor or oil cups? I'm not familiar with the blower, if it has a gear box then the oil ressivor May not hold oil or oil the gears and bearings. Some have separate housings for the gears and blower and can be indexed to alow different configurations. The same problems with oiling cups. Of its one that runs on greased bearings.then it shouldn't be a problem Quote Link to comment Share on other sites More sharing options...

Charles R. Stevens Posted March 2, 2013 Share Posted March 2, 2013 Then try to use sweeps instead of elbows. The gentler transition to 90 deg. Will create les resistance due to friction. Quote Link to comment Share on other sites More sharing options...
Joel OF Posted March 3, 2013 Author Share Posted March 3, 2013 Sweeps? Do you mean laying it horizontally? Quote Link to comment Share on other sites More sharing options...
Charles R. Stevens Posted May 27, 2013 Share Posted May 27, 2013 Sweeps are long gentle bends in plumbing pipe as apposed to abrupt turnes. Bends restrict air flow, sweeps less so. Quote Link to comment Share on other sites More sharing options...
