Welding Table

[woodzy]

OK - here is mine

Started out with an old frame from a piece of equipment at work:

View media item 90669
The Frame had four hydraulic cylinders that can adjust it up to 9" higher
View media item 90672
Clean it up a little
View media item 90670
Make tops and assorted steel support –purchased a Harbor Freight tool box and cut it in half.
View media item 90671
Buy / Build some components - had to move the crank system to the outside to fit in the tool box.

Small project in action

The frame under the tool boxes being welded.

Thanks for looking - it is pretty heavy to push around – I might need to look for casters that roll / rotate better. Changing directions takes all the power I have.

That is beefy! I really like the adjustable height. Is the sheet metal guard to protect the crank system?

 

[zmotorsports]

Nice.

I like the height adjustment. How do you keep the cylinders all in time with each other?

Yes, the crank has plastic hydraulic lines that run to each cylinder from the pistons attached to the crank. I figured with the sparks it should be protected. I ended up adding a sheet metal pan under the table and above the frame to keep stuff that falls through the slots in the table. I can't tell you how many times you go looking for something that dropped through.

It has just over 9" of travel. If I use it often, I'll make some attachment for my drill to run the crank - it takes a lot of turns to get 9" out of it.

I think the unit I have has four cylinders in the crank section and when you crank it in - it displaces the fluid to the cylinder at the table - When you crank it back the weight of the table move the fluid back to the cylinder in the crank. The fluid does not exchange to each cylinder - four different circuits. I would guess there is some feature when it is all the way back, the fluid will bleed back to keep it all level. Pretty simple idea and it works.

This was on the frame I got from work - these were used to make this ergonomically for the different height line operators.

that's very nice, I got the same clamps from HF, can you tell me how you made it work? I was going to weld a 5/8 round rod on the end.

and did you make the silver stops and spacers yourself? I am looking to buy some 5/8" tooling if you make them.

Nice, that is a well built table.

Where did you get the ball lock bolts from?

I made a jig that once I cut off the end of the clamps, it clamps into a jig on a slight angle. I purchased 5/8 bolts from HD and got them long enough so the first 5/8 (maybe 2") or so had no threads and cut them off with the bandsaw at 5/8 long and welded them on.

As for the spacers, a buddy made them for me.

I "googled" the part number and I think it was from Zoro or some site like that - they were not cheap but were about 10% cheaper than most places.

Way too difficult to make that part.

Wow, that looks sturdy! Any idea how much it weighs?
And those hydraulic jacks are neat; good to have stuff adjustable. What are they from?

 

[zkdiesel]

Super nice. Jealous

It must weight close to 1000 pounds. As for the hydraulic jacks, they were part of the frame we had at work. It was to adjust it for the height of the table for different height workers. I actually have a 2nd set as a spare in the event one fails.

Nice job, how did you do the tops?

 

[woodzy]

Nice job, how did you do the tops?

Cut top with CNC and then Ion Nitrated them. I wish I make the holes .001 larger as some time it is hard to fit the pins in there. I tried to flap them with emery paper but they are very, very hard... Nice thing about the hardening of them is the splatter does not want to stick. If you hit it with a file it just skids over it.
