barrywhite 282 Posted December 29, 2019 Report Share Posted December 29, 2019 only posted this because I just got some .66 green gzk rubber I cut four strips 15mm wide a 9 inch active length a draw of 44 inches shooting 11.5mm lead balls with power of about 13.5 ft lbs this was shot in a cool environment . I just made this catapult I dont know why catapults like this are not mentioned more . you get better power and accuracy and no hand slap . OK you cannot slip it in your pocket .My main reason for thread was the GZK bands I thought would be just the same old hype about this rubber , Its my first set of bands with this stuff it seems very good . I usually use theraband gold just putting this here for feed back . 4 Quote Link to post Share on other sites
Mr Wilkes 3,036 Posted December 29, 2019 Report Share Posted December 29, 2019 I’m sure Greyman has some of those , as for the gzk green I’ve never used it but heard good things about it Quote Link to post Share on other sites
Welsh_red 4,690 Posted December 29, 2019 Report Share Posted December 29, 2019 I made one at home from a old hospital crutch . Greyman set me on my way with that. Your one looks much better tho as irs not as clumbersome as a crutch Quote Link to post Share on other sites

whipbed 42 Posted January 5, 2020 Report Share Posted January 5, 2020 very nice catty Barry i didnt know about the gzk rubber so i bought 0.8 green i dont have a crony but it does seem better than theraband it lasts longer and for larger ammo you dont need double bandsets for small ammo the bandwidth can be cut a lot narrower than theraband the only problem i have now is that i need to work out the best band size taper etc for my needs where i had more or less done this with theraband keeps the hobby interesting though the other variable is i have only tried 0.8mm and there are a few thicknesses to try Quote Link to post Share on other sites
