Ok, so at night, I'm in constant fear the smoke detector will go off. No clue why. How can I get rid of it?
I don't know much about gluing PVC but from the pictures it seems to be a fairly poor mechanical design. It's basically a crank with two pedals (maybe for use with hands as well as feet), right?. The crank seems to be made out of pipe sections and 90 degree elbows with nothing actually making it rigid except for the glue, so all the loads will be going through the glue. A swimming pool is a fairly harsh chemical environment because of the additives to the water, and rehab pools tend to be more heavily treated than normal pools because of the increased likelihood of people with infections using them. That might affect what glues are suitable. I would be inclined to think about putting some pins or dowels through the joints, so there is positive location of the parts preventing them trying to move around, and the dowels will carry the shear loads and torque from one part to the next. The pins could just be thin PVC rods (say 1/4 or 1/2 inch diameter) through suitable sized drilled holes. If the PVC is generally strong enough to take the loads (before the first failure ocurred) then you don't need metal pins. The main function of the glue would then be just to stop the thing falling apart, not to carry the loads. It's not clear whether you are need take the thing apart or not, so apologies if that advice is impractical.
and with ur chest, like mine, just what kind of race car could girls our size fit into? :)) and do they MAKE firesuits that big in the chest for us??
