Hydraulic Press safety questions

I use the old brake drum on all axle bearings and I add a 2" thick piece of steel with a 2 1/2" hole in the center and it's about 8" round this holds the drum down because without it when the bearing pops or breaks the drum will jump up and parts of old bearing will fly out and hit you in the legs which is not much fun. just be careful whenever you are using the press and use good judgement if it looks bad it is going to be bad.
