The gun was built to run full auto all the time. Converting it to semiauto should lower the stresses of firing. A crank spadegrip will only somewhat increase your rate of fire, but no where near the original full auto fire rate of 600 rpm. The additional stress will be on your wallet and ammo stash

+1 on that your good to go with the crank just watch your headspace since you will be heating up the barrel quicker...

Who made the right side plate? Years back there were some plates which failed in semi. Others can chime in on who produced them.
ORF had good RSP and Daves 100. I have two made on Daves plates and run a OBSheep crank with no problem other than ammo.
LOL.....Weasel

The only concern you should have is what type of rear buffer assembly are you using? If it's a standard length you will have no problems, if it's the M-37 or short tanker buffer you will most likely damage your gun. Aside from that you should suffer no ill effects.
Thanks, guys. My dad said the side plate was made from 4130PHT. He works for Boeing and has all kinds of metals available. Knowing him, this must be the best stuff.
The manufacturer of this crank/spadegrip says if the gun runs well in semi-auto, then it will do 600 RPM with his device. In fact, he guaranteed it. It has an adjustable flyball governor that has graduations from 350-650 RPM. With the governor adjusted to the ideal fire rate for this rifle, he said it will fire at the preset rate +/- 5RPM no matter how hard you crank. He said that was added to eliminate the 'loping' that those cheaper cranks do. It was pricey, ($875), but it's built like a Swiss watch. I'm going to test it this afternoon.

Well so much for my thinking you'll never achieve 600 rpm with a crankfire adaptor. I just got schooled

Hang on dhuchz!! VA and Shawnia have now carefully set the stage for the Grand Entrance, but you gotta wait for the cheering crowds to DEMAND the main performer appear on stage. When you hear the drum roll begin, followed by the sound of a Piper Warrior buzzing the audience at dare devil altitude, you'll know it's time for the "Master Mechanical Inventor of EVERYTHING" to walk among the mortals and reveal the MAGIC CRANK!!!!!

well EJ,
actuallly thought it was YOUR crank (which no one has ever said wasnt a nice part).... or maybe that you had came up with something new?
but as usual, all you really want to do is show up, complain for a post or 3, take some cheapshots at members, tell the world how great you are, then let everyone see what a total JERK you are.
your mission is accomplished bub.

I , also thought VAGunner was talking about Emory's Spadegrip Crank. I bought a set from him about a year or so ago and think they are the best out there, bar none. I also have one of his original cranks which I think are great also. As far as RPM, I have witnesses ( some of who are on this forum ), who claim I run faster with my E.J. Crank than they can with their F.A.'s Chime in guy's if you want.

Wow, to hear you talk one would think that you invented the wheel....
Or at least laid claim to it.

No he just patented the wheel, so any time someone talks about a wheel that may not be his he unleashes the DOGS OF WAR (lawyers) on anyone who dares challenge his claim to the wheel. Its funny he is so sensitive about something he no longer wants to produce. Why not let others take up the gauntlet and try to produce a better wheel? this reminds me of the old daffy duck cartoon where the genie shrinks him down due to his greed, bugs finds a pearl in an oyster and little daffy runs up throws himself around the pearl yelling "IT'S MINE ALL MINE!"
"I'm RICH!" I"M INDEPENDENTLY WEALTHY!" Well I don't own one if I wanted one I'd build my own, for my own use, he may own the concept, till he sues someone & the challenge ends up in court, levers, cams, springs, cranks, have been around longer than this device and no body holds patents on the bits and pieces and its just a matter of finding the combination that his patent does not cover. Let the drama and the high blood pressure begin!
