Hi Ralph,
    Loved your site.  Must be nice to work in so organized a shop.

    I would like to read the article as I will be pouring the babbit in my
hammer.  I had seen an article somewhere but can not remember where.  I also
suspect I will be pouring babbit in the clutch hub also.
    Do you preheat the frame with a weed burner or rose bud before you pour the
babbit?  How do you recommend squaring up the shaft to the guides?
    I think I am going to mount the motor to the side also.  Seems like the
easiest way to go.  Thanks!

Larry
