Two Wild Turkeys - over ice.
Look up how much torque the nut the size of the one on the crankshaft will take.Reading these post, I have a question. How often has a a crankshaft nut been twisted off (destroying the crankshaft) while using the starters that uses a socket on the crankshaft nut? I have a few starter/generators I could use with a belt reduction to the crankshaft nut. It just doesn't look right using the crankshaft nut.
That's what I thought too.Everytime I see the term "TWT" I immediately think Traveling Wave Tube. How geeky is that? That is one of many leftovers from a previous career.
I've seen impact guns used but I don't know if that is good for the crank.Although I have been told it is unsafe, I have safely started TWT's for 30 years with a 1/2" drill and a socket/adapter.
I am 6'6", so that drill doesn't scare me.
The 850rpm Porter Cable I bought 10 years ago works fine.
If it looks too dangerous, get an overrunning clutch off a 8N PTO and put it in the middle.
I tried using an impact wrench, but the fact that it operates by repeating impact instead of with a constant torque makes it unsuitable. I'll try an electric drill some time when I'm feeling reckless and see how that works.I've seen impact guns used but I don't know if that is good for the crank.
Which is one reason I'm building a TWT with a Westchester engine. Although it will be a wide wheelbased one and having a 50" deck out front. With Hand Brakes.
NO ! :Stop:I've seen impact guns used but I don't know if that is good for the crank.
This is a neat rig, but we're still driving the engine via the crankshaft nut...That's basically what a friend of mine that lived in OH - Jerry Donahue - designed to facilitate working on both electric and non-electric starters more easily. In essence a portable, mirror image of Gravely's electric start system. He'd planned on making more units but moved West.
Considering what Ive been hearing about the possibilities of breaking that shaft the pulley-nut is on I wiuld be more comfortable making sum starting machine that just turned the pulley itself, like something that will grip pulley like a wheel puller just for the shape of it and maybe even have do drill 3 or so small as possible to work holes in pulley to attach something to it ( roll up to it , not permanently) but not affect the pulley spinning true or weaken it.Perfect! If a 12 volt starter motor isn't available, a 3/4 or 1 hp 1725 RPM motor should work too.
I wanna have the Gravely hobby for the rest of my life, cant afford to restore old MOPARS and got more guns than I can even shoot much less need but I gotta get myself back to decent health or Im gonna need something to start em with.
Is that a Gravely starting sprocket or flywheel on that starter?I wanna have the Gravely hobby for the rest of my life, cant afford to restore old MOPARS and got more guns than I can even shoot much less need but I gotta get myself back to decent health or Im gonna need something to start em with.
And plus I at least wanna get one that runs wich I more than likely did but took it apart first but that was my mistake.
What I worry about w/a drill like mine and I guess the rest of them to is the initial shock of it coming on. All of a sudden its like full on blazin. Would be nice to have some kind of spring or something to dampen it at the initial power burst.
P.S. Nice looking rig.
