I'm interested to see how you go loading with a full preload ie the rubber attached close to the trigger on the underside. Looking forward to seeing some pics when you get the gun made. good luck.Really? I thought it would be easier to load in water when you can twist and bend your body in any way necessary to load it lol
That being said, I don't live near him so I can't try his. But loading it will never be an issue. I'm a gorilla and I'll load anything necessary when it comes down to it.
The only reason I was suggesting to get the large shark fins is to have the line attachment in the fin instead of the back of the spear. If you think it will be okay in the back of the spear I'll just use the spears I have... the wishbone won't slip off the mini sharkfins guaranteed.
Thanks for all the useful info! It's greatly appreciated. I'm gonna buy the bands and other accessories today, so when they come and I set them up I'll post some pics and let you know how it goes
Its all about transferring the power of the rubber to the spear, with your old setup you had 51 inches in total of 16 and 18mm rubber applying power for 36inches (46 - 14(length of 1/2 rubber plus whishbone)Okay guys, I need some serious help!!
This thing is impossible to load!!
I did the 2ft of 18mm rubber on each side like you suggested and added some preload (about 17cm) and this thing is ridiculous
I'mm sure I'm using the wrong material for the bridle (2.2mm dyneema). I guess I need something like 5m or more. But regardless, with the length of the gun i can't get the bands to even budge from the roller.
So I retied the wishbone (made it shorter), and also put no pretension on the bottom. This time I was able to set the gun... barely.
But my problem is this. If I use virtually no pretension and set the 24" bands to the last notch on the spear I'm getting just about 300% of stretch. (From the muzzle to the sharkfin is 46" so call it 48" and that's 2x the relaxed length which equals 300% right?)
However, if I use a normal setup with a normal muzzle, I would use a 27" 18mm band, and a 24" 16mm band.. and if you calculaate the band stretch for both of those, isn't that WAY MORE power than the roller set up above?
If I calculated right, wouldn't you take half the length of each band, and figure out how much it's being stretched?
So for the 18mm - (27/2 = 13.5 then 46"/13.5= 3.4 which is 340% of stretch
Then the 16mm - (24/2 = 12 then 46"/12 = 3.8 which is 380% of stretch
Someone please explain how this roller gun is better then my regular setup... Did I just waste money trying to make my gun look cool?
