Jointing table lift

I bought a homemade woodworking machineDuring work, I really did not like the adjustment of the planer table according to the depth of planing. The adjustment was carried out using two homemade screws when adjusting the screws, the table skewed.
IN the garage lay a broken jack from the classics and I decided to adapt it for alteration.Sliced ​​a little long.
It took more time to mount the jack lever to the table, since it is made of duraluminAll this is pulled up by springs for more precise table setting.
