well, I did not get arrested yesterday, but I sure didn't get far with that lock. I drilled and drilled and drilled, small bits to larger bits until there was nothing left of the lock mechanism and it still would not let go. grrrrrr.
ok, brute force time. Headed back at it this morning with a helper, and we will take the wheel off the trailer, clamp included, cut the clamp off with my new 10amp Dewalt compact sawzall with lots of metal blades (didn't want the huge conventional style-too heavy) and I will cut that sucker off hopefully without hitting the tire.
well, kudos to the clamp maker, can't fault the thing doing exactly what it is designed for, preventing brutes like me from stealing the boat...
