Cool, the vintage 50 ton journal jacks make excellent stands for pickup trucks up to semi's (probably loaded as well),the 10" height is kinda like a niche that makes it handier than most stands, even SIMPLEXs is heavier and slightly higher that keeps it just sitting around, would be nice if you or someone else would make a affordable one for us prosumers.
Why is something so well built not meant for regular use? I want to build a new style of Rosin Press but there is so little information on these units I can't figure out if they are appropriate.
This is kinda out of my league but there are other companies that make what I think is called a "linear actuator "....anyone feel free to add something...
