Po Boy Power Draw Bar for the PM935

[bretthl]

Not much to say here except I have a better spring coming. Use a 12 point 3/4" impact socket. I ordered a nice Ingersol Rand butterfly impact and realized there was no clean way of mounting it and it delivers way more torque than necessary. There was a crack in the housing at the nose so I returned it.



The lesser brand was 1/4 the price and has a nose more adaptable for mounting.



For added stability I mounted a steel bushing (JB's your Uncle) -



All the parts and pieces (the base and risers are 1018, the bushings are Al-Bronze and all else 6061) -



assembled -



Mounted and tested. I like it, balance is good, no binding. Spring is so-so and will replace. 60 psi through 3/8" is sufficient torque.

I keep thinking I want to make one with a pneumatic cylinder to push it down and all that. But this is style sure would be easier to build.. Nice job!

Very nice simple good looking tool.

Here are pics of the one I built a couple of years ago with a CP 3/8 drive butterfly ratchet wrench. I added the push button valves just to be different, they work great.
