You aren't going to see a bunch of closeups of my welds because 1
don 't weld very often. They aren't pretty, but they are strong
enough to keep every thing together. Once the frame is together,
clean the rest of the rust off the meta l. You can do all this cleaning
work prior to assembly; J just like to leave the th orough cleaning
until the end (sec Figure 6. 18).

Bearing Rail Support Bolt Holes

I chose to drill the bearing rail support bolt holes before painting
so that I wo uldn 't damage the fin ished surface. The bearing rail s
are 6 feet long w ith ho les drilled and tapped on II -i nch centers
start ing 3 inches fro m each end (see Figure 6.19).
