Promise is a promise..........
Last Saturday I managed to do a short test on that Slip Tip my friend gave me. I used it on my 32" x 5/16" on my Metal Tech Zero. I borrowed the Riffe Ice Pick slide ring.
First Test :
Drop the slip tip from 10" with shaft and all, on a wood floor. The Slip Tip ejected nicely.
Drop the slip tip again but this time on my ceramic floor, same good result, but believe it or not the fine small tip get a bit dull....really a bit only.
IN WATER TEST :
3 bands x 9/16 on the MT0. Shot a small fish and the tip get ejected, didn't get the fish though. Shots two more fishes and lost them too. I thought what's wrong ????
I tried shooting at water with 4 x 9/16 bands on the MT0. The Slip Tip disengaged in flight......DAMN !!!!!!! I think the pure G force of the shaft acceleration ejected the Slip Tip prematurely.
I again tried shooting with 3 x 9/16 bands in to the water. Out of two shots, one shot got the Slip Tip prematurely ejected. The other shot the slip tip sits nicely without premature ejection.
Conclusion :
Let me sort out the premature ejection first. I have a new spring which is 1 cm longer and thus harder. I hope next trip I can get better result. I can't test penetration, accuracy or holding power untill I get the premature ejection sorted out. I was worried it will never eject, at least the ejection machining part works well, that's the hard part to deal with.
Will keep u guys updated.
While I was at it, I shot my Apollo 11 shaft for the MT0. The Apollo 11 is the 9.5mm (3/8" ) shaft which I machined the foward part to be come 7mm ( 9/32" ) Hawaiian shaft. The shaft has the tendency to shoot high at 4 and 5 bands. In fact very high. Must learn how to aim with it. It wasn't shooting left/right, that's the good news. I done only very few shots because I was also playing with my Mares 85cm Cyrano which just got a modified Riffe Hawaiian shaft.
My Cyrano shoots funny, I think my shaft whips. I just pumped extra 50 pumps of air into it for this test and use 3 wraps 200# mono. If I gues correctly it is actually still under or close to 30 BAR, its maximum. It is much more powerful than before but I guess it is now over powered. Playing with two guns on scuba at 50 feet made me loose my Mares loading handle. Managed to load the Mares with the small line hole on my Riffe knife....neat.
I recalled using the original shaft, spearhead and 400# mono, my Mares was shooting left ( not pumped extra 50 yet ), now it shooting a bit high and quite erratic with so much air I pump into it and having a more sleek shaped shaft. I can't seems to hit 3" circle from +-3 meters. The only consolation is that at 3 wraps, it still have left over energy to tug my gun, much improved. This Cyrano is my first experience with 7mm shaft on a pneu. I think I prefer 8mm shaft of the Sten :waterwork
Need to experiment again.
