welding fixture table top

[Dirtmotor]

Finished up the fixture/welding table top ! Used 5/8 steel cut it out on plasma table . Its 32 x 44 with 77 5/8 holes on 4 inch centers , I sealed edges of plate with masons flex self stick flashing then soaked in 50/50 muriatic over night to loosen mill scale .,It rinsed almost clean then flap wheeled . Tacked 1 1/2 square tube on back and set it on shop table (with tractor) . So far its working good still making some clamps and other tools for it .

Great looking fixture table. Have always wanted one but I can't afford it so would have to do something like that. Pretty slick

Looks pretty sweet. Post up pics of the clamps that you come up with>
I was thinking of purchasing a mag drill to make one. Since I didn’t want to chance burning one on my 45xp plasma cutter. But a little thinner , maybe .375 or even .25”

I did borrow a mag drill , and used a annular cutter, worked great ! Bit was cutting the same on last hole as it did on the first .

This is first clamp , made it out of a couple 5/8 bolts , a 3/4 nut ,3-1/2 nuts and some 1/2 all thread and one 5/8 id bore shaft collar,it was pretty easy , swivel foot is a 1/2 inch nut with all but one thread drilled out and a washer , had to grind small ball on end of all thread leaving a couple of threads on sides , then welded nut to washer with thread turned up, screwed it on to ball and works great , does not fall off .

That's a great looking fixture plate. How flat is it? Nice job!

Not perfectly flat but close enough , its as good as you can
get without surface grinding .


Don't know who's quote this is but I like it !

“The bitterness of poor quality remains long after the sweetness of low price is forgotten”

Buy the best tools you can afford.. Learn to use them to the best of your ability.. and take care of them...

Looks Great.

I saw your clamp setup and it made me wonder why you chose the oversized slider nut instead of another set/shaft collar above the lower stop set collar. I assume that the slop is needed in the oversized slider nut so that it grabs instead of pulling the pin out due to too much vertical lift without enough bind instead of a lateral bind that might occur with the oversized nut? Or........? hmmmmm
I haven't made a fixture clamp before, but am I close??

Doug - I think you are correct in your assumption. Here are several of mine. Part of the force applied at 1 is transferred to 2, causing the pin to bind in the table hole and prevent lift.

Yep need the slop to lock in , the horizontal rod is canted down slightly as well as the nut for all thread, so force is aprox. straight down .
