Vintage Windmill and Wind Generator Forum

Hello all,

I see lots of good info. sharing here in the forum and am offering what I can regarding a Beatty Pumper rebuild I'm working on. It's all torn down now so if anyone needs any measurements or pics of anything please reach out. Not sure what model I have but see letters PB1 on the gearcase casting and it's 8' dia. rotor. A couple of rotor arms need replacing and I got them out without issue. Is there a simple method to get the radius bent into the new ones after flatening the end?

Thanks,
Scott

Hi Paul,
If I can't find arms for my Beatty I will have to make 5 of them.
Did you use a conduit bender?

hey joe
its a real process you have to heat up one side only then beat it over a die i made to get correct shape
took me a while to figure out how to do it

Paul I am guessing it is better if you heat the stretching part as opposed to the shrinking?
Have you tried both ways to see which way worked better?
Thanks.
Joe

if you study a factory bent wheel arm it is not collapsed in the middle its all on one side has been a while since i made any takes a while to get back in the swing of things to remember the technique

Thanks for the info. Paul I will have a good look at the original before I start and let you know what works best for me. It will be an interesting challenge.

I have one original so that will be a big help if and when I have to make them.

Today I took the arm off the two sail sections it was tying together. There is only about 1/2 inch of threads left.
Me thinks that may not be enough. Not good.
