Check my reply to your thread 'Rolling Mill'.
Use of hydraulic jack can be found at https://www.garagejournal.com/forum/...d.php?t=222930
This is the only reply that I see.
I could see how the jack lowered the casters but could not see how they were retracted untill I saw the Norlift site and finally see the springs for retraction.
Here is my reply to your thread "Rolling Mill". Can be found at page 2, just before you wrote that your mill fell over backwards.....
Ralph, I fully understand you as I have the same problem. Very small workshop (3 x 2 meters) and I also must be able to move my lathe and mill around in order to put them in their final positions. I made it little bit differently and I used idea at The Heavy Bench - The Garage Journal Board. Have the same bars with casters and same hydraulic jacks for both.
2 pictures attached.
oh, I had forgot about that incident!! Yeah the heavy benches, machines need to move around especially in a small shop.
I am "thinking" about taking my Mill off it's stand and mounting it to a heavy bench, which again would be mounted on casters.
Now I need some more detailed pictures of exactly how your retraction springs are fitted.
I didn't put retraction springs at all as I didn't need them. When the bench is on the casters just move it around the workshop and once bench is in it's final position, just open release valve at bottle jack and bars with casters will lift up. Actually complete bench is coming down and then it stands on the feet. As I have the same bars, casters and hydraulic jacks for both; lathe bench and milling/drilling machine, I keep bars with casters on one which was moved last. In my case at lathe bench.
