RE: Magnesium Riser
 

Magnesium riser are cast out of a mold,or more correctly,a die.AND yes,they are not as strong as billet aluminum risers.I have seen them break in 2 at the grip.Glad I wasn't hanging on t it.;)


BUT,let me add that the technology today is leaps and bound above what it was just a few years ago.The newer hoyt magnesium riser are practically bullet proof.

Aluminum risers are cut out of extrusions,not forged.I would personally like to see a forged, aluminum riser.That would be the most stable and strongest riser one could get.


I believe forging will be the next technological advancement in riser design.Might even be a dropped forged riser.

Arthur,where you at? I know you have some valuable input on this subject.

BowTech's risers are forged and then machined.

RE: Magnesium Riser
 

I know that Bowtech and , pretty sure Martin, claim their risers are machined from forged billets of aluminum.

From Bowtech
Martin advertises this on numerous magazine back covers.

RE: Magnesium Riser
 

BUT,they are not forged,they are cut from forged billets.

To my knowledge,most still use 6061 extrusions.

RE: Magnesium Riser
 

I was not aware that these companies were using forged billets.Might be a step in the right direction.

I had a Hoyt Ultra-Mag at one time and it was mag. I never had an issue with it and it seemed durable as can be. I have never heard of any of the newer Hoyts made from Mag breaking but i have heard people talk of older bows breaking in the riser.

I believe the PowerHawk, and the SuperHawk are still made from magnesium. The SuperHawk has laminated limbs as well.

The problem with the casts/molds is stuill one of air pockets and other imperfections. Start taking a good look at the Reflex Growlers/powerhawks/superhawks at full draw- you will see the occasional one that flexes (for lack of a better term- bend) at full draw. Jimmy Despart started to notice this (he runs Flying Arrow Sports II near Albany)- and now my my local shop (original FAS) is keeping an eye on all of them when they come in.

This is nothing new however- my first Magnatec (Powerflex w/ C cams) had this issue. At full draw you could see the limb pockets lean to the left as cable tension was reduced at full draw.
