Vintage Windmill and Wind Generator Forum

I poured the bottom of the main hub on a Pipe Raymond this afternoon. I allowed it to cool for about 5 minutes and lifted the shaft out. When it was time to clean up the extra the whole new babbit what is now a very nice insert lifted out. My surface was sandblasted spotless clean. Did I not have the casting hot enough? I am wondering why it let go. Thanks.

For what I know that is the way it is supposed to work. I poured one half took it out used my same set up and poured the other half, but I don't know if that is how the old timers would have done it???

As long as it's poured in a anti-spin cavity or divot of some sort it will be okay. When in doubt glue it in. The weight is on it anyway. But it really needs to be in a divot of some sort.

Would LokTight be a good enough glue?

This is what my dad did years ago when I helped him pour the bearings on a open geared samson. This technique prevents the babbit from turning or moving in the shell. https://www.rotometals.com/babbitt-bear ... -bearings/

I don't know about loctite. Maybe. I have used a variety of glues on occasion. Remember, windmills are slow-speed machines. There is a variety of things they will forgive you for.

Good information. Ive got to pour some at some point and need to get a plan in place to get my woodmanse poured. Ive never done it before and i want to ensure i do it right and have the correct materials. Ive been trying to gather references and watch youtube examples but cant seem to find a lot of examples on windmills.

A person needs to know where the oil passages are, so they don't plug them up. Woodmanse has a couple that need to be known about, that are maybe not so easy to spot.

If you you would have drilled some divots in it first it wouldn’t have come out. Or asked me when we were on the phone and I would have told you that. But I guess some have to learn the hard way.
