I missed a couple words in my last post until i just read it.I took the stock cylinder off the ryobi and turned it down so its round so it looks more like an airplane engine.The last time i ran a lathe was in high school so im just starting to play around with this.Ive made some 6 bolt prop hubs,single hubs,timing sensors out of flywheel centers,ect...Im finding more uses evryday.For instance,my son needed a heli coil for his aluminum eldebrock intake manifold.Well,ya have to buy the kit.I have drills and taps,i didnt need the kit.heres what i did:
Drill out existing hole for 7/16 tap
tap 7/16ths course thread.
chuck 7/16ths all thread in lathe
drill out center,tap for 3/8ths course thread
cut off 1/2 - 5/8s inch
install in manifold with a little locktite.
my Cost==25cc maybe------------helicoil kit=$17.00----$22.00-plus,what do ya do with the leftover helicoil parts?
I also have a little twin project im trying but its not going real fast.
