i did it to remove and replace the camshaft bearings in the Chevy SB, no hammer or beating needed and risk to damage the new bearings.
not a big deal but it works fine and fast.
it's composed with two aluminum bushings, one with that one with blind hole threaded that goes into the bearing inner diamater and the other one that goes in the block's bearings lodging, just to keep the threaded bar centered ,a big washer and the threaded bar of course about 5/8 diameter with relative nut, that's it, evarybody can do that with just a lathe.
the first bushing (threaded) can as you can see in the picture also be twisted inside the camshaft "tunnel" so you don't need to pass it through all the bearings journals during the process.

thank you guys,

i was in doubt about the material to use for that so i thought steel too but i did them with aluminum to avoid damage at the bearings itself, it would be sensed if beating or hammer is used but it insn't my case , next time i'll do them with steel because i saw that rod is pretty much centered and cannot nick or bent anything.
i agree about usinf a partially threaded rod to avoid damage at the bearings and faster too :welcome:
i already experienced that when in the journals bearings are crushed so i' took off a little bit more with the late in the diameter.
have a great day!

love this tool. Glad I seen this.

to the top for others to view (again)

thank you, it's so much apprecciated,i've made some little modification and the cast iron ring has been replaced by an aluminum bushing, i can grab pictures if you want and all the dimensions if you want to build your own one, just let me know,
talk soon

sorry for the delay, i've loaded some pictures of it.
as some fellow said, is much better to use a partially threaded rod, so you can avoid to nick the cam and save a lot of time, i didn't because i'm not using that so often.
