I had a bad Ebay experience. I bought 2 new props at auction. They were sopposed to be 1 1/4" bore but turned out to be 1 3/4" bore. I got a hell of a deal on props that will not fit. The guy so far has refused to take them back.
I got to thinking, I can not get a bore reducer that will go from 1 3/4 to 1 1/4" I have used them before with OK results but still I'm not fond of them. I am wondering, why can't I make a set? I would make them from bronze. I dont have a good way of creating an inside taper and particularily a keyway. So i thought I could start with a 1 1/4" bore junk prop. I could cut the blades off then turn a proper SAE std. 1 3/4" taper on the o.d. of the hub. milling the external keyway would be fairly easy. I could offset the i.d. taper keyway and the external o.d. taper easily. I would want to control the external diameter so that the new bushing did not extend behind the prop hub. There by insuring the prop washer and nut only contacted the prop. What is the opinion of this?? would it work? I have a engineering background and have toolmaker connections.
I am looking for a 1 1/4" bore junk propeller hub at least 3 3/4" deep. I need to be a large diameter ot be that deep. I already have one. Ideally the blades could be sawed off to save shipping .
What think thee?
