I'm having an obscene amount of trouble finding a US company to make a two piece prop. I went seaching through the list archives and came across this topic. In it, Snoopy suggest that a Sierra prop get shortened on the motor-side; everything else--including the center bearing--is used as is.

Is this true? If so, it is much easier finding the Merkurs (US Sierra equivalent as I understand) to donate the prop.

Any help is appreciated. I would hate to pay the post cost from BM, you know...

--Thanks, Chris

But what is the process in detail? You use a lathe to lop off the short end. It looks like the slider goes on the engine side. Is this correct? Forgove this question: are sliders commonly found at propshaft builders?

This is not really a project I'm keen on tackling myself, so I need to know what to tell the machinist/prop welder.

Like I said, I'm having a terrible time with this. I would like to have specific instructions to tell the builders. Also, what speed should the prop be balance?

--Thanks for all the help.
