ArcFlat Welding Table

[robert-r]

I bought one. Liked it so much, I bought another. https://www.langmuirsystems.com/arcflat





Sure beats my self-made uneven table. The clamps and etc from Strong Hand tools make assembly so much quicker.







Together the tables weigh about 320 pounds. Added casters and can roll it around with one hand. Very happy with this.

Langmuir is local to me - saved $200 on shipping.

Was in a hurry to set the first table up and use it, so I bought the leg set. I needed to shorten the legs and add casters to match the table height of other benches/tables in the garage. The legs are 3" square tube. When I cut them down, the wall thickness was was only 7 mm and the inside of 3 of the legs were rusted. They do seem to support the weight, however I would make them myself if I was to do it again.

With the first table I bought, the holes were too small on the top. Not wanting to exchange it, I drilled them out to 5/8". Probably not the most elegant solution as opposed to reaming them (no reamer), but the clamps and etc seem to work fine as they operate on a bind system. The holes on the sides of the table are sloppy at around .041" in diameter plus or minus. The second tables holes in the top are fine. The holes in the sides are the same as the first table. Am not sure if the holes in the sides will present a problem. So far, haven't needed to use them.

I purchased their special bolt kit to join the tables together. I carefully followed their instructions and double checked the setup before injecting the fast set epoxy and clamping the bolts down. Where the tables join, they aren't totally horizontal about the last 9" of the seam. Shee... It's very slight - maybe 1/32" at most and not really a problem to me so far (I put that part of the table to the back). A chunk of aluminum bar stock 1 x 2 x30" set across the tables show the joined tops as flat. Am not sure if I messed up in assembly, but think it's a machining issue. One table edge "slopes" off starting about 3" from it - about the width of the machining bit.

I need to correct a few items in the original post since I can no longer edit it: The wall thickness of the square tubes was .070" not 7 mm. The holes in the sides (random sampling) range from .0629 to .0641" in diameter - not .041" diameter.

I am thinking of buying an arcflat table. but i need to be able to roll it around in my garage. has anyone added casters to this table? if so, can you tell us how you did it? i am not sure if i should use casters with a post (threaded) or if i should weld on plates so i can bolt on the casters. any suggestions? recommendations on casters? can you provide some pics of your caster installations?

it seems to me the table is priced reasonably and fixturing should help with my weld projects. any feedback is appreciated.

[robert-r]

I used these: https://www.amazon.com/tonchean-Leve...167176&sr=8-16

They work very well. Can easily roll the table (on cement) with one hand. Gotta keep the floor clean - they don't like welding bb's etc.

robert-r, thanks for the feedback. i ordered a single table 24 x 36 and the legs. once i get it i will give more thought to what kind of casters i want to use on it. your choice is interesting.

[BillE.Dee]

did you give thought to step down casters? step on them to raise the table on wheels and lift them to set the table back on the floor.

Here's my 2 cents : weld some 3/8" plate to the bottom of the legs. Then drill and tap some holes to bolt the casters on. Bonus points if you can add some jam nuts to the bolts.

I think what 52 "meant" to say was drill and tap the plate before welding to the bottom of the legs...

I've been debating the purchase of one of these tables but in my research I haven't been able to find anything about the thickness of the tabletop. Can you provide an measurement?

TIA

Robert-R I am not sure of the need for the third hand assembly when you are clamping directly on the table???

[Freebirdwelds]

Looks like a nice *** table. Kudos.

2nd ground to the welder so it doesn't arc to the table top?

Not sure about that. Hasn't happened so far. fwiw - I keep a smashed braid of 12v battery wire between the work clamp and the table.

It's approximately 3/8" thick. It's a sand cast table and the underside is rough. Not a problem for me, but ball lock pins don't work.

Thanks for the response. Can you elaborate on why the ball lock pins don't work? I Assuming it's the thickness, or lack there of, of the table.

They need a smooth surface on the underside of the table. Also, it's the thickness of the table.

Nice table
My line of work was to big for tables.
If lucky it fit on horses and shim the work or horses to be leave. Other time for larger work 4x4 on ground.
The only plus was a rake for cleaning the ground.

Does anyone have any ideas on building some legs to make the table able to tilt?

I'm working on an idea for that very concept for my dual Certiflat 4'x3' tables (essentially 4'x6'). I'm going with a very, very heavy base that has a small foot-print so that I'll be able to tilt the table and be able to roll it out of the way instead of permanently giving up 24 ft² of valuable floor space when I don't need to use it.

Think like an old drafting table

Somebody posted one a while back that slid up tight against the wall when not in use as well, and folded down onto retracting legs when horizontal.

Something like this would make for a pretty sweet "fold away" table. Maybe get 2 or 3 pairs of them. The 16" version said 550Lb load cap. I'm sure they're talking about 550lb to make it fail and they don't have any safety factor there.

You push a tab in to release the latch. Maybe get some 1/4" or 3/8" rod and weld it across the tabs to tie them all together.

That sounds awesome and exactly what I’m going for. I’ve been trying to work out how to make the pivot point since there isn’t a centered hole on the table to use and the ribs on the inside look to be right in the way to drill your own.
