Yep, 3/4" x 1" roller bearings are easy to source.

captain awesome said:How refreshing. Someone actually using math and calculating what will be necessary to "upgrade" the suspension and addressing the stresses placed on the frame while doing so. We need more of these threads, keep up the good work.

VERY nice build. ACTUAL build.

An observation, if you are so inclined: You could substantially increase the swing arms rigidity to vertical plane deflections by, instead of the single connecting tube from the upper bracket to the swing arm, using two that connect from the intended shock mount to near the ends of the pivots. Incidental improvements can be had by avoiding the bends in the upper hoop where it contacts the rear of the arm as well.

(Here are some of my rambling thoughts and compliments)
Nice work! Clean welds. Good fab work! Nice workshop.
Which miller tig is that in the background?
Nice table. I welded one almost exactly like yours about 7 years ago and it's still going strong. Have you seen those stronghand tools weld tables. I wish I had the dosh for one of those.
I just got Tony Foales book. Did you see his suspension program? Might come in handy if you plan on doing this professionally.
I'm bracing an xs750 frame and used solidworks to run some finite element analyses on the frame. Took a huge amount of time to set up but it was very fun and interesting seeing how additional braces affected different parts of the frame.
Plan on bracing my swingarm. Would love to read more about your work! Especially the jig.
I'll need a tubing bender and I'd love to get the JD squared one. More $$$.
Great job so far. briefly looked at your #3 build. To be able to sell one and say you turned a modest profit is pretty impressive.
