Possible Log Splitter Cylinder ?

I'm sure the OP knows this and I don't know if this has been covered already in the above posts but ram material is 4140 induction-hardened chrome stock and is harder than hell. You will ether need to spot anneal it with a torch or grind through the coating with a grinding disc because standard HSS tools wouldn't begin to cut it.

Just a heads up.

its more of a case hardening... it goes around 1/4"-3/8" deep into the round, cut it with a grinder, or an abrasive chop saw, as for the hole in the end, if you don't have carbide tooling cut "flats" on either side of the rod, so the end of the rod is more of an oval shape to get past the hardened material

The induction hardened shafting is maybe 1/8" deep on the shaft. You can cut it with a chop saw. If you plan to turn the shaft, take a torch and run in a lathe at low rpm and heat it till it just starts to turn red, then let cool. Use carbide to cut with.

If you've never worked with it before, it will be very frustrating. However, take your time, measure twice and cut once.

Cut the rod with an angle grinder or chop saw. I wrap in in a paper towel and tape the towel on before clamping it for the cut to protect the chrome.

Cobalt bits work fine to drill them. The chips will be gritty when you go through the hardened layer.

It isn't hard or troublesome at all.

apparently its different between manufactures, i useto work for "woods" which is a bucket manufacture for heavy equipment, and had tons of cylinder rod stock (all sizes) and the hard layer was always thicker than 1/4" EXCEPT on small diameter rods (under 1-1/2"-2" or so). i had cut some parts out of it before an a wire EDM and you could clearly see the hard layer in the round, i might still have the drops from those somewhere?

Well, I contacted Tom and bought the remaining 8 cylinders. I managed to convince a couple of friends to take 2 and I need two, so I will have 4 left for sale. Freight was the big kicker. Shipping from WI to NC made buying just two to cost prohibitive. Actually freight doubled the cost of just 2 cylinders. Buying all 8 lets me spread the cost. Hopefully, I can sell the remaining cylinders locally, or I will have lots of spares for my processor build.
