Here is a picture from BP series 1 manual. People have said that the ram dovetails carry the load. Of more concern, should be the cast iron cross, (p/n 118), that the four turret locking bolts thread into, which holds the ram on, is intact IMHO. The four tabs are only about 5/16” or less thick. The last BP that I picked up for my son, we made a castered dolly with built-in leveling screws so that he could roll it into and out of his horse trailer on the beefed up ramp that he made. The dolly is sort of like the one pictured here, but improved.
