Has anyone used the compression block from 3 Rivers Archery? You heat it up and spin your shafting through with a drill to heat-compress your shafting. I was wondering if you could compress 3/8" shafts down to 11/32? It's a little spendy, but it would be worth it if it would allow me to compress a full 32nd of an inch.

You beat me to it JD.I was just looking at that in the cataloge last nite.

I really need to add some weight to my shafting but I like using Doug Fir. I thought the compression block may be a good option for me if it will allow me to compress the shafting enough. I may have to switch to Hickory shafting with some of the bows I'm shooting to keep around ten grains per inch.

You can soak them in danish oil to add a little weight. I think it adds about 50 grains max. Justin

jd if you do use it you need to up your spine about 5 lbs. if i remember the last time i used one it was set up for 23/64 to 11/32 and 11/32 to 5/16th. an easier way is to use gasket laguer. each coat adds 10-12 grains depending on if its new or been in the tube. i dont reccomend really going crazy with the laquer. but up to 5 -6 coats doesnt hurt and you could use it to dial in the weight of your shafts. im able to get my shafts within +-5grains.

Thanks for the ideas guys. My arrows come out around 600-650 grains. I would like to move up to 800 grains on a couple of my current shooters to get ten grains per pound. I've shot my prospective hunting bow with 1,000 grain oak arrows a couple times and it handles them well. Maybe I'll just try hickory and see what I think. Or, I could do some long footings with Ipe?
