Prop Shaft

Have any of you guy's cut a slot in a shaft using a lathe?

I watched a video of an old guy who made a v-clamp that bolted to his tool post and that is what he used for cutting keyways. Seems like it would work pretty good, especially if you only have a lathe.

It's not WW2, there's no need to be that clever. Take the shaft to a shop with modern equip and pay to get it done. <<<<<< Not trying to be a dick with this. I'm just saying, is the 50-100 dollars it's going to cost, worth all the effort of making something like that? I've run conventional lathes, mills, screw machines, grinders, threadrollers, etc. Now days I wouldn't even think about it with the technology that's out there in the machine tool world. Unless, you have a lathe and you like to tinker.

No worries, I don't think you're a Dick. I like learning some of the info you provide. I'm just a Hillbilly that likes to tinker with stuff on nights and weekends and the shop's are'nt open then, so it's not about money more like convenience to do stuff when I can. As far as the effort of making something like that, I'm sure I could copy it in about an hour.

Funny, that was my first thought. Then I started thinking maybe he somehow locked the spindle and the end on a center, and used a cutting tool to broach a slot by dragging it over the shaft multiple times.
That's what I get for thinking too much:happy:

They had a profiler of sorts, they called a broach, at McCulloch that rough cut the crank forgings. It look like a chain saw and threw chips like one.

Danny Bell (562-577-3673) has long narrow tapered collars that are drilled with a series of tiny holes in a way that deliver water to the strut bushing so they mount close up to the strut barrell. It's really an ingenious design, and are not as blunt as the one pictured in the RexMar pic (sorry!!) and not likely to divert water from the prop. Heath Hiebert uses one on GN369 and it works great. I think Jim Wilkes sells them too.

I was going to run this safety collar in front of the strut what do you guys think?

Nothing wrong with running a 2 piece in front of the log this would be in addition to the 2 piece in front of the log. I guess you could run a 2 piece in front of the strut too if you don't like set screws. What is the problem with set screws?
