Hi Max,
Yes I had to make new rods yesterday to fit in the puller because they are 3/8th unc and I only had 10mm rod here. The amount of pressure I had on it I thought was going to break the puller and from memory I paid about $60 for it and I wasn't going to destroy that all because of a stupid boss that I had plenty of in a box that owe me nothing. I have thought about some sort of porta power head I could adapt to it but for the number of times I can't get them off it probably isn't worth the expense I have always used angle iron on these pullers and they are multi drilled so I can use then for all sorts of pullers, not just the bearing puller, the angle gives it a lot of strength although it does have a bit of a bend in it these days
