This is what I bring out when I have something like 1 inch plate to drill...
...no extension cords needed and the battery only requires a few bud lights to recharge.
Someone makes a tool specially to bend and put that seal in, but I don't know where you would find one. I wouldn't put it in boiling water, but set it in the sun or put it in warm water and try that.
Companion is just what the name says...the guy you take with you on the trip to Alaska that you can kick in the knee and leave for the bear to eat while you get away...and definitely not who you could count on when your in a tough spot..not worth a plug nickel if you ask me
