Fact. The cut down pedestal allowed me to windfoil 3 hrs on 99 infinity, no issue at all which is unprecedented for me.
Fact . Im shocked by how much more stable the foil feels to me. Massive increase in confidence. massive decrease in crashes.
Fact. despite the completely unfinished shaping the extra drag was unnoticeable to me.
Speculation: Its so much more stable I speculate that the wing resists instantaneous roll inputs and with my weight flexes mico amounts at the mast fuse interface. Given the weird angles the foil is traveling through the water, (slight up, slight yaw), any flex, steers the foil in weird ways, possibly even stressing the fuse mast interface even more. Generally the wings may be balanced but surely they resist rapid wobble movements. Water at speed is pretty resistant to sudden roll movements. I think this is why the set up feels so much more stable now. This could loosen bolts, but even if the blots are red lock tighted any micro flex in metal is going to eventually fatigue, and snap.
So how do you get super red lock tight broken bolts out of the mast. Speculation : this is a bad idea.
Opinion: I love and highly recommend slingshot gear for wind foiling. I highly recommend the 84 and 99 infinity wings for heavy weights. However my suggestion is that for confidence in not snapping bolts, and even more so for a much more stable enjoyable ride, the cut down pedestal is a dramatic improvement, and I hope slingshot bring out a purpose built adapter.
Great to hear your solution worked for you. I agree that using red lock for the bolts is probably a bad idea. I think that the screws coming loose happens
after some "forwards and backwards wiggling" of the mast. Glue won't change that, so the risk of bolts breaking remains .. and getting the remains out would be a real PITA.
How tight is the fit of the mast in the pedestal adapter you used? For some of my older masts, the fit is just somewhat tight, the masts are still easy to get out. But for my newest mast, I always have to use a rubber mallet to get it out of the pedestal.
Also, when things were still braking, did you use the Slingshot titanium bolts, stainless steel bolts, or both? There are some statements about titanium being more brittle than stainless steel, causing "brittle fractures". When the strengths of titanium screws is touted, it's usually in the context of strength-to-weight ratios. Perhaps important in airplanes, but much less for foiling. Neither is the higher corrosion resistance relevant, since the aluminum corrodes quickly with both titanium and stainless screws.
