Best WBL sabot design yet!
Posted: Fri Jul 15, 2011 1:16 am
OK I'm going to go out on a limb and say that I may have found the perfect sabot design. I based it on the gold standard found here: http://forums.sscentral.org/t4638/
I tried to make the above design using a pringles can and also using a tennis ball can. Both were just a tiny bit too big for my 3" barrel. I suspect it may be because I used schedule 80 PVC not the standard schedule 40 stuff, but this is just a guess.
The sabot fits the barrel with a few millimeters of clearance, so there's little friction upon launch. It's possible there is some blow-by costing me distance, but I get almost 400ft @ 90 psi so it seems to be working pretty well.
Design improvements:
- All plastic - no paper, cardboard or tape to get wet and deteriorate
- Uses only two components: a plastic bottle and some foam
- Made of tough, rigid plastic to last a long time
- Fits a 3" barrel perfectly -- perhaps a millimeter or two of clearance.
