You need a jig or there is a possibility that they will warp and then they are junk so make sure you get a someone that has done this before. Pay a little more now or a lot later.

Thanks JR, I'll do them. Takes 2 to 3 days. (Once there here). Thats all I do to the rods, just Heat treat, Quench, and Temper. someone else will have to size them. I don't have a rod hone for that. It's 220.00 for a set of 6 or 8, and free shipping back to you. US Only.

Heck yea, 75 bucks for Cryo, and you don't have to resize them. I'd like to do a 100 ton side beam break test on that. Does anyone have side by side test info ?

I don't see how cyro can come even close to adding as much strength as heat treat. From my understanding cyro just reorganizes grain structure. Heat treating a rod up to 40rc probably adds 40 to 50 percent more strength. Be interested to hear some opinions on this

I'm just cuious what needs to be done after hardening. Is it as simple as resizing the big end and rebushing the small end? Do they stay straight during hardening? Do the sides need to be reground? Shotblasted? Any info would be great. Thanks
