I started this shop press 15 years ago and never had time to finish it. I cut the 3x3 angles, punched the 1" holes and left it sit in the corner. Then one day i needed to use it to broach some keyways. So i went out and welded it all up then i went to my machine shop and turned the parts to hold the hyd jack and the bottom tooling. The jack, bed plates and bottom angles are all removeable because i am also going to use the frame with a chain fall to raise my 2 metal lathes up to put the legs under them. Then i can bolt the press parts back on. I could use a little bigger jack but it works for U Joints and my keyway broaches just fine...Bob

Well after using my press for a few years with the 6T jack i finally upgraded to a 12T. Just had to make some new attachment points for the bigger jack. Also made a rack to hold some of my quick change tooling...Bob

It is SOOO good to see a piece of equipment made by someone who knows what they're doing. An air over hydraulic press and you be stylin.

Thank You Frosty...Bob

Not desireing to be critical here but years ago I got some real schooling on these things. Your machine is a well thoughout item that has a great purpose built design. Congrats!

 

Now for the other part. DANGER lurks near in your design!  The cross piece that goes fropm one side to the other that keeps the pressing operation straight (under the jack) is quite a bit undersized. Not that the metal cannot take it when everything is perfectly aligned, but that is when things start happening. The longer the pushing rods, etc the more angle of deflection there exists. WHen you have 10, 20, or more tons pushing and suddenly "shivvers", as when a bearing is being inserted, then an explosion of metal flying everywhere happens. I have seen it about a gozillion times.

 

Remedy: look at commercial presses and compare the spreader bar that goes under the jack. See how easy you can adapt your project, and implement. Live a good long safe life!

 

Carry on

Thanks David. Here is another attachment i made a few weeks ago. I needed to break down my lawnmower wheel to add an inner tube and couldn't get the bead broke. So i made a small breaker that slips over my 1" tooling shaft. Worked great...Bob

great set-up.

Those bolts along the center make me think the system is like we used in aircraft. That is the rim assembly comes in two separate pieces. But the tire still must have the bead broken away from that rim. Be careful.

 

 

Carry on

The rim is a welded one a bead right in the middle. The bolts are from the hub as i never unbolted it i just pulled the center bolt and removed the whole unit. The wheel is from an old 80's Yazoo 3 wheel rider and it just turns in a frame as it swviels to steer...Bob
