Lots of questions , Mark.
The factory programming was very good on mid, at least to the 200 bar area, so in the interest of not f##ing it up, didn't change anything there. I lowered the voltage on pl 3 to bring his velocity down to the appropriate velocity region for 18.1s and made some small changes in pulse to extend the pressure range some. The polishing process is tapering the leade some, rounding the leading edge of the transfer port and using JB Bore paste and Bore Bright to blend and polish the bore. The wax is Mother's Carnauba with no polishing agents(important ), applied and buffed 3 times as discussed in a couple of other threads. If you go to the Meguiars web site, they have a very interesting blog on Carnauba wax ..... very worth reading . The orings are the best I could find to extend the time between replacements and are a blend of Viton 75D and 90D for static ones, depending on the pressure , and cast polyurethane for the valve stem. There is a plan to get some 70D cast poly for the breech, but will have to be tooled up, so Viton 75 for now. It's been excellent for me, anyway .
I've worked with a couple of others where we have helped each other to find all that we can do to make this platform as perfect and durable as possible. It was at a point for me initially that I couldn't shoot 75 shots (EBR 50 yard minimum ) without a degradation in accuracy because of leading and last year blew a valve stem seal on the first event. Even though it still shot okay, nowhere near as good as going into the event. The others have similar experiences. Not the best preparation on my part, anyway. I had just been shooting it a TON and tuning to find where it was good.
There may be other methods for getting there, but this is how it's developed for us. I DID NOT want Centercut to have to go through those same things.
An interesting side note is HOW GOOD the Bleu Wolf seems like it wants to shoot the Beasts, but has those danged fliers. Something else to figure out.....
