I figured I'd post some pics of the table I've been working on at work. It's a 20ft fab table that I'll be working off of, and was built almost entirely out of scrap metal we had laying around. The frame is 12" channel, with 8" square tube cross members. It has two 3/16" hot rolled plates (I wish they were cold) that are supported by 2" 6ga square tubes. Overall, the table is perfectly flat (within a 1/32), and should be perfect for me to work on. I just hope the plate is thick enough that it doesn't end up bowing if I happen to strike just the right place. It'd be a huge pita to replace the plates, but it is definetly possible.



(neglect the retard...err coworker in the background.).







I always take pride in my work...


Just thought I'd share...
Enjoi,

Nice work, I wish my table was that nice. Half the time, I use a 2'x2' plate on my wood table.

good work, looks like pretty much the same design as the skids i used to build and the bed truck beds too hah


when i do a flat table on my truck it'll be 1/2" minimum. 3/8 is too thin.

Thanks guys!

Yeah, I wanted to use 1/4" but my boss just went ahead and ordered the 3/16"

IMO, 1/4" is perfect because it would take a huge impact to deform the surface, but it's not so thick that it wouldn't flatten out nicely accross the frame of the table.

we actually have another 20ft table that the guy used a 1/2" plate for. The plate has several high and low points that are almost 3/8" off from the rest of the table. It would take over 10,000lbs of dead weight to get the plate to bend enough to be perfectly flat. The 3/16" stuff just laid right on, and only took 3,000lbs of weight to form it perfectly flat to the frame. It was extreemly important that this table be as flat as possible, so the thicker plate just wouldn't have worked.

we have a 40 ton leveler at my work, about the strongest in the US

heres where i work

lemme know if you ever need some steel i work in the heat treat/ quench and temper dept, we make some seriously hard ****!

cua0

the last shop i worked at that had a fab table, it was 1 1/2" or 2" thick (i don't remember, it was really f*kin thick), we also had one that was 1/2" thick but warped to **** anytime you welded on it for a long enough period of time.

PeeFo

nice table

daralekt

thats one heavy duty table for sure!

Bakeoff

I can see you taking out your leg on the lower corners of the I beams... YIKES!
Aside from that, looks awesome.

Bailhatch

looks like a nice build quality.

I would ruin it in one day though. My 4'x8' welding table is 5/8" hot rolled and it's really the minimum I would use. There are a few 1/2" ones in the shop that are a good 3/32 out after a few years of use, especially the edges where they have a little overhang.

what are you building on it?

Niles

If I ever did a lotus seven project I would kill for a nice tough table like that! Nice work.

Bryson,
GREAT WORK! Was just wondering exactly what you mean when you say it took 3k lbs to make it lay flat. How are you ensuring it is flat? Your basically putting 3k lbs on it where it is high, and then welding it while the weight is on it?
Just curious...

??? Theres not a single I beam on this table lol. But whatever your talking about though really isn't an issue. Everything besides the plate and the ends of the channel stick out at all. The corners are all rounded as well, so it won't gash my gut if I walk into it.

Yeah, like I said I was really hoping for 1/4" cold rolled. That surface would last forever and be perfectly flat. I can get away with the thinner plate because of how much bracing I have underneith. Those square tubes are definetly not bending, and make the plate so much stronger. I build a bunch of stuff, but I mainly build stair assembilies, landings and hand rails for our patented modular stair structure. Because a lot of this stuff is huge, and requires pretty tight tolerances (not aircraft by anymeans ) that table had to be at least 20ft and be perfectly flat. If I build a stair assembily thats just a 1/16th off, that could be over 2"s at the other end of the stair.

Hell yeah! I just wish I could take this one home with me...haha. The nice thing about working at this fab shop is that I have a lot of tools and machinery at my disposal.

lol...I was waiting for this question haha! But the plates, no matter what thickness type of steel, or who made them will always have some form of curvature to them. To get them to lay perfectly flat on the table I put 3,000lbs of decking material (bunch of 3'x5' sheet metal) on the plate, then tacked underneith. I just moved the decking along until I had the whole plate tacked down.

However, the most important part was obviously making sure the frame was perfectly flat, since the plates just get pressed onto it. Luckily enough, we have a 25' x 10' leveling floor (1" plate) that we use for "mods" to ensure that they are perfectly flat and square. We installed it directly to the concrete of our shop, and shot every 4"s to a precision of a 1/32nd. It's pretty much the flatest peice of floor that your going to get without having a CNC big enough to be able to cut a 12" thick plate that size But I simply laid out the channel and support beams on this leveling floor, and welded it all together. The sure weight of the tacked members made sure that it didn't deform due to the welding. I also made sure to just tack the plate instead of weld it, to ensure that the heat wouldn't deform the surface.

Thanks for the explanation Bryson! Appreciate it. Think I understand the leveling plate you guys have, but a visual helps! HAHA. If you can, itd be cool. My uncle works for a satelite company that builds all the satelites for DirectTV and Dish Network and what not...and they have jig tables they use for assembly. They are made of 4" thick marble and I know are perfectly straight as well. Would try to get one, but cant tack stuff to it! HAHA.
Thanks again for the explanation!

Yeah I don't think I can get pics of it, but it's not all that complicated. Basiclly 4 huge plates with holes symetrically placed every 12 inches. The plates rest on tons of bolts with spacer nuts which were shot in perfectly level. Once the plate was on, we simply shot the plate again, and tightened down any areas that were high to match the rest of the plate. Once it was all flat, we welded the bolts to the plate, and cut the ends off.

A marble table would look SWEET! Although I'm sure it would just crack or chip if it was struck with a hammer (marble is soft as hell). I actually have family that lives up in Marble Colorado where the largest marble quary is. Theres just huge chunks of marble just sitting next to the road...so cool to see. I'll see if I can get some pics up!

the angle cuts on the base of the table lined up perfectly for your craftsmanship.

I need to build a table like that. My stuff is EVERYWHERE. Organization owns me....

I know how you feel. This section of our shop was horribly messy. I'd literally take almost 3hrs a day just looking for the right tool. Now with almost everything I need in it's own location, I know exactly where the tool I need will be.

Bah server down.

Nice work. Organization is a beautiful thing.

It seems like the servers been down for almost 3 days.
