I was hoping that you would see my build, I was inspired by your rebuilds, so this is me saying thanks.drgary wrote:Porter, essentially you have cobbled yourself a Conti Prestina with a large boiler.
On my Prestina, where the group is fastened with 4 bolts, there is no "give" on the pull. You should be able to figure out a way to brace it to eliminate the flex.
Thicker steel slats in the front, where the groups are bolted on would be the trick. I tried twice to ensure that it would not flex, but its just so much weight transfer. The piping is holding fast to the frame, which is where I am concerned. When the boiler flexes forward, the pipe connections do not. Now that I have the original PF in place, it stops pointing dead outward, so I use that to lift upwards to counter the movement.
