I been working on my oba for a few days now. I have the diy bracket tac together. But I but I notice that it a little heavy. I made the bracket out of 1/4 plate steel. Is going to be to heavy for the bolts that hold it on? I really don't want break those bolts out.

 

As long as you use some grade 8 bolts it should be fine. Where are you mounting it? Any pictures? I have 2 York air compressors sitting in my garage and want to mount one in mine.
