Need to get the knives out what's the trick to getting the Allen bolts broke loose dang near twisted the Allen socket off with 3 foot cheater pipe with no luck thank u all in advance
 
Never had trouble getting mine out but at this point about all that's left is to drill out the heads. Start with a 1/8 or 3/16 drill in the bottom of the socket. Probably Gr 8 so push hard and keep the drill speed slow. Oil won't help. Step-drill the hole up to a size about 1/16 larger than the thread diameter. When the drill gets close to through the head the tension will pop it off. The hard part is drilling out the hex socket.
 
(quoted from post at 17:38:27 05/19/19) Heat it up then let it cool. Get new bolts, never seize the threads, put them in and have no more problems in future.
this method will work. warm it up and rapidly cool with wd40. repeat several times and the bolt should be removable.

Do you have a welder?

Do you have room there to weld?

Find a nut that has a center hole just barely smaller than the head of the allen bolt. Hold it in place with a box end wrench to center it on the allen bolt head. Weld that sucker to the top of the allen bolt.

Let it cool. Spray with penetrating oil when it gets cool enough to not boil off. (some people swear by touching with a wax bar... I've never had wax around to try...they say the heat melts it and draws it in).

Then put a "real" socket on there and remove the bolt.
 
heat from the gas wrench will help it break loose. Heat red hot let it cool, wax or penetrate as it cools. May take a time or two. Sometimes I don't even try to break a bolt loose until after heating it up. I use wax also. No accetalyne oxy torch, time to get one. gobble
 
We used heat and when the heat was removed, candle wax. The cooling sucked the candle wax into the threads and the bolts came out. Put everything back together with anti-sieze.
