mabe some crazy glue..................

admin

Ok mabe not on the glue..this was a shaft in a khun rototiller that drove the top chain sprocket before it sheared off..now the question, for the most part its not weldable to put the end back on, so heres a question for the machinists out there, whats the cost..give or take.minus any shipping costs...or if its possible to re machine new splines and threads on the remaining shaft?..and moving down the bearing surface..the other end of the shaft slides into the gearbox, but doesnt need to slide all the way in, originally about a good 6 inches slide in, the sheared piece is about 2 inches long so that would leave about 4 inches to slide in the gear box, approx weight on the shaft is 22 pounds..thanks for any info..Of all the things I lost I miss my mind the most...I know just enough about everything to be dangerous......You cant cure stupid..only kill it...
Reply:I'm just a construction guy who watches a lot of youtube videos ...I'm thinking if you had access to a lathe and drilled each piece to accept a pin....bevel it ...then weld it.
Reply:If you had a way of centering it good you could drill and tap both ends that are broke and insert a threaded stud into it. I did this for a few small shafts with sprockets on them until I could get a new shaft ordered. You could use about a 5/8" bolt in there and not sacrifice to much of the outside for strength. The ends would half to be ground so they mate up fairly even but not to much to shorten the shaft.GalenMiller TrailBlazer 302 EFIThermal Dynamics 252i w/WeldCraft WP 9F tig torch and foot controlThermal Dynamics Pak 52Millermatic 250 w/Spoolmate 30aLincoln SA-200 gas driven welder from grandfatherBlacksmith shop
Reply:I ended up buying a new shaft and of course the spacer was different so more money, ended up around $300.oo tax and shipping. I thought about drilling and using a bolt, and welding, but the stress that shaft is under is tremendous, and its takes a few hours to open up the rototiller and exchange it out, also theres a big *** and im sure very expensive bearing the shaft rides on close to where It would have tobe welded, and im sure if it was the slightest out of round it would wipe out the bearing or something else..If it could be machined for a reasonable amount I would have it done and keep it as a spare for the next time..Of all the things I lost I miss my mind the most...I know just enough about everything to be dangerous......You cant cure stupid..only kill it...
