Love it!! Here is the trick, pack bearing and lube the threads. Get 2 large washers for under the bolt, be sure to lube them. Tighten up, check fit and try again. Do not try to do it all at once, do small steps and it will stay round. Patience is the trick. Leak free snug fitting joints is what you will get. Yes it does help to lightly anneal the pipe too! Little bit of propane to warm it up. Good luck, go slow, lots of grease and you will love this tool!!!
