Hydraulic Jack Knob

[dlsmith]

I saw a couple of items on Amazon that were knobs/extensions to attach to the valve on a hydraulic jack that obviate the need to use a slotted handle or such to tighten and loosen the valve, and Saturday I made my own with a knob I had in my collection, a piece of 3/4" bar stock and a little lathe time. I turned on end down to 5/16" to be threaded for the knob, and drilled the other end 11/32" to fit the valve stem and then cross drilled it 9/64" for the cross pin. I threaded the end, knocked the cross pin out of the valve, inserted the valve into the adapter, drove the cross pin back in, installed the knob and a jam nut, and now I have a much easier way of turning the valve on the jack on my press.
Took me a total of about a half hour to make it.

Very nice. 30 minutes well spent!

Great minds think alike!

Pretty skookum. Only a half hour, I’m way slower than that. Just don’t let someone toss the jack in the back of truck or in a tool box. I think I’ve got a selection of those busted knobs.

I recently did a similar mod to my press. I like your ingenuity for sure.

But I am way slower than you, so I took the "path of least resistance".

I just couldn't pass this up for 14 bucks. (according to my order, I paid 13.99 6 weeks ago, but I see they have increase to 16'ish)

This jack is dedicated to press duty. I've never taken it off the press, as I have two other jacks I can use if I need one.
