more GM questions

[the other DWS]

I have a GM riser that I picked up mainly to get the limbs that came on it. I also have some 34# GM limbs that I got in another deal to get the riser it came with----this is what Bob Gordon can do to you if you don't get inot some sort of 12-step program.

Anyway just for curiosity's sake today I took the riser and the limbs and put'em together and took'em to the range to shoot. borrowed a rather heavy over waxed flemish string from the shop rack to shoot it and was using some 400 gr Beman 400s cut to my 29.5 length-----verrrry interesting. the bow has a rather beat up old springy type rest . I haven't shot a bow with that light a draw in years but was kind of fun and rather educational. I can see where it will help me a lot working on form when I can hold full draw for as long as I want. I even worked on some eyes closed shooting at 20 yards. .
Now for the questions: there seemed to be a LOT of after shot vibration in the bow. I figured that 400 grains would be plenty for #34. flight wasn't too bad but they didn;t have a lot of penetration in the bags at 20 yards. I let a couple of other guys shoot it too just so I could watch the limbs and see what was going on. the limbtips were really bouncing around after the shot. I stuck some limbsavers on the fadeouts and and borrowed a "vibration absorbing stabilizer", they helped some but the limb tips were still doing a real Fred Astair. The limbs are regular old white glas and wood GM marked limbs. Is this kind of vibration normal for a GM. The overly bee'swaxed string was actually sticking to the limbs in the contact area and that may have been a factor too. Other than that it was real sweet shooting.

I doubt I'll want to keep the GM--too long and heavy for my preferences in any case. I'll have to put the 36# Zones I have on the MIzar and see how that goes for a learning bow. I have a lot to work on--technique wise

Wayne, for years I shot 58"-60" wooden recurves. When I went to the warfers and got a set of 36# Zone medium limbs that make a 64" bow, I noticed quite a bit of limb dancing going on. From what I understand this is somewhat normal for longer-limbed bows, although you didn't mention what length those limbs are. I have that red BW 34# target bow that's 67" and ya ought to see those limbs dance... but it plugs 'em right in there very consistently.

its long, thats for sure---the reaason I was stuck with the sticky string, it was the only one I could find quickly that was long enough--and that just barely. Its out in the car right now, but I think it says 66 or 68 with a 25" riser on the #34 limbs . Maybe if I get time tomorrow I'll try it with the #38 Zones, put a different string and a better rest on it. I also dug out some of my old AFC 1880 Electra/Exacta target arrows, some 2200s, and some 2400s just to see how they do out of it

[Pinelander]

Betcha those 2200's will shoot real nice, but the 2400's will have to be pretty long or heavy up-front out of 40-something pounds. I've got some 2200's fletched up at 29.5, 30.5, 31.5, 32.5 and the rest are unfletched, waiting for the tuning results of my 40-43# Zone-limbed Warfer geting ready for turkeys.

[the other DWS]

the 2400s are my old compound arrows the camoed "stealth" version--I have a couple of dozen of'em full length with 125 gr thunderheads, used to shoot'em out of a 72# 31" overdraw oneida--extreme penetration-had one do a complete side to side pass through--through the head-skull of one buck--it was a lousey bad flinch shot on my part but it dropped him in his tracks absolutely stone dead

I also have noticed a lot of limb bounce and thrashing when shot from a light weight bow that is pretty long in length. I think it is because they don't have much tension on the string when strung, I could be wrong but about every light weight fita type bow I have seen has done the same thing. I guess it's because the limbs are so long, thin and flexable compared to what we usually shoot, guess you just have to live with it. Maybe limbwalker could jump on this one as I know he spends a lot of time watching the collage girls shoot Olympic archery and maybe he to has noticed a little "limb bounce" when they shoot. ..LOL...warf

[the other DWS]

Bob I somehow doubt we are talking about the same "limbs" but those GM limb tips got more moves than the Dallas Cowboy cheerleaders. It shoots nice but a bit distracting. maybe the slightly heavier Zones will have a bit more tension

DWS -

Yes, no and maybe.

The GM is a very stiff riser, and you're shooting fairly thin limbs, so there's going to be some vibration. You didn't mention the type of string material you use (or if you did, I missed it, sorry, old age and late night). I use B-50 on my ORs and every thing else, and that adds to the vibration. Also, ya might want to check the tiller. It's adjustable on those things, and if it's gotten out of wack, whick they do, that can add to the vibration. Playing with it can help, but usually not eliminate it completely. Start with 0/0, then start making the lower limb gradually stronger and see if it helps.

I've played with that damn riser for over a year, and it still drives me nuts.

Viper out.
