Shop press needs reinforcement

I tried to press out the inner race of a deep groove ball bearing and those things can take a lot more force than I anticipated. That is 3"x 1/2" thick plate/ I heated it up, straightened it in the press and tacked 2 more pieces of 3/8" thick x 3" plates in place. Then followed up with 200A full penetration 6011 welds to make sure it  stays in place. The cross beam alone has to weigh close to 50 lbs now.
