Does anyone have any info on hardening a kickstart spindle? Do you case harden or through harden to a specific rockwell? Does anyone know the actual material used in the spindle?
I'm going kick only and I don't want to have to open the case again if I get heel heavy during a tough start.
YOu are new enough to the forum you may not have read what I've been thru. SOme background:
RC (Russ Collins) Engineering used to sell a shot peened/heat treated spindle. I wanted one for my project. No sources. So I looked into it myself. Shot peening was found about 4 miles from my house. THey had a minimum shop order, so I got 3 done for the same price as 1.
Next I found heat treaters on the southside of Indy. But they asked the same questions as you, what is the beginning Rockwell number and specifically what is it made of? With no answers they said they didn't want to do it. TO get the answers would be cost prohibitive.
So Ecosse (I think, may have been someone else, apologies) introduced me to Cryogenic Treatment. THis is all the rage now in racing circles. Google it to get your own background. But essentially, it convinced me that Cryo was just as good as heat treating for my purposes.
I found a source in Lebanon IN but the proprietor had business at some race shops near my house and he picked up my shafts personally. Cost was really cheap.

I sold the one extra I had to a forum member and am keeping the other 2.
