I have the 30 ton H Frt model which has an A configuration at the top. It is not as solid looking as Mad Mackie's, but has been a good unit. The frame is the "erection set" style with adjustment holes. I bought this around 2000 on sale for $160, but stuff was missing when the tractor trailer delivered it. In one of the only hassles ever with H Frt I finally ended up with 1-1/2 press frames, but still not everything I needed so I made the missing stuff-easy. Before this I only had a 3 ton arbor press now stored away. If you have even a small urge for one , buy it and you will not be disappointed.
Here are some of the uses I have put this unit to...Bearings, seals, suspension bushing removal and replacement, making small parts, using to test auto spring rates, as a fixture during a transmission rebuild . You can change the crossbar alone, one pin at a time. The 30 ton bottle jack is not necessary, but I have never had to use the long arm on it. Only nuisance on mine is that the retraction springs do not fully return the ram (jack piston) to the down position so I usually have to help it (the last 1/2 " travel). A key to versatility is a collection of tube, pipe, plate as Mackie's 2nd pic shows for set ups. Start saving old bearing cups, auto hubs , pipe , etc. Sockets can be used. You may find access to a lathe useful in difficult set ups. Sometimes I wish for the 100 ton ironman type with real press punch capability, but these littler ones are a great addition.
