The silver brazing joints that you upload, are they just finished with a hand file and sandpaper or do you use some tooling?
Cheers

Usually a file and shop roll (sand paper). If I get a bit out of shape with the brazing I might knock it down with a really slow rpm die grinder.

Always been a big fan of the turner DHR style linkage driven single pivot. On closer inspection this looks a little different, probably even better with an Horst link.. Are you going to 3D print the seattube tunnel? Looks awesome!

Yeah, this is a four bar Horst design. Shock driven off the swing via the linkage to seperate the wheel path from the shock progression. Though they are still tied together of course. What was really interesting in designing this bike was how much the Horst pivot position affected the leverage curve. Just a couple mm had a big affect.
Yes, teh whole middle section on teh bike is 3D printed. I couldn’t find any rectangle tubing of the right dimensions to reduce the printed section so. Any of the oval tubing wasn’t squashed enough for my design but I might be able to do my own ovalising. I really want to reduce how much I print the two uprights. have doen some preliminary pricing though and it is isn’t too bad.
