It's a really nice Hammer but the only thing bad about it is it's not counterbalanced very important thats why its jumping around if you bolt it down that will put more stress onyour welds and could be dangerous .thats why the hammer drops to the lowest position when you stop it should float to wherever it stops at and it will be easyer to get it started if balanced 👍👽👽👽
very good work friend, I would like to know if you have plans or some information to try to make an equal, I know it has a cost but I am willing to pay for the information. regards
