6.5' x 10' x 1.25" thick steel table top. Weighs in at 3380 lbs.

Got some frame material coming tomorrow. I'll post up the pics as we make progress.
 
Score the material for cheap/free? Wondering why so thick...

Seems too small for a table you'd build a truck on is the only reason I ask.
 
Big enough to jig up some bumpers on both sides and smaller things in the middle.

That's gonna be nice

I did get a great deal on it. I like the thickness for the weight, ability to resist warping as well as being able to drill/tap holes in it for fixturing.

All depends on the wheel base as to how big of a chassis you could do. Little less than the 120 would work on here, if you needed to have the axles under it at the time.

I have a few things that I want to build right away and need a big flat table to do it on properly. Beyond that, I have a Camaro, a motorcycle project and oodles of other things this will work real well for. If some day I wished I had something longer, I could pretty readily sell this one and build another.

Been considering a sacrificial top for it. Maybe 3/8" thick plate the same size as the top or even 1/4" thick would work. Something that could be welded on and generally abused and then replaced at some point in the future.

Plans for drawers/tool boxes underneath as well as an axle for putting on some truck tires and a hitch point for the fork lift.
 
Always wanted a huge table like this. Now that I have a shop. God willing I will build one some day too. Props and can't wait to see it in the build process.
 
Are you going to mill the top flat somehow?

No. There is flat and then there is flat enough. While milling it would make it better, some of this stuff you have to keep an eye on reality and understand what will get the job done and what is unnecessary. We've already had some straight edges on it and its pretty damn flat.

Gotta have a D60. The 10b would snap shafts as soon as you went crawling with it :haha:

[Actually, at that kind of weight, you would need a 14BFF wouldn't you? :doah:]

Yep, you're exactly right. We have some extra 14BFF's around and that is what we'll be using. Set up like a trailer axle, I believe its a 70/30 split for axle location. We may even put a coupler on it. We have a ball for the fork lift fork and move trailers like that from time to time.

If you don't have a mag drill already, see if you can borrow one or rent one from a tool rental house. They are perfect for drilling and tapping a plate like that. We used to use them at the bridge fab shop I worked at in college as well as the tool and die shop for drilling and tapping eye bolt holes in large plates.

1.25 is a good thickness, and honestly its pretty thin to the rest of the industry. A 2 or 2.5in top isn't ridiculous for doing heavier work.


At that thickness and width are you going to do truss style braces across the short side?
 
We have some 3" thick huge tables at my work. Can't get pics though. So much want!

Mag drill is the only way to go.

1.25 is plenty thick for what we intend to do with it.

We flipped the plate over today, that is an interesting thing in and of itself.

Cleaning off a bit of surface rust before starting on the frame work.

Tacking on the first pieces of the frame,

I remember when I did my 2x4x3/8" table, puny by comparison, flipping it required some fun involving a come-along and the engine hoist and such. This thing ... forklift? chain hoist? How DID you do it?

Forklift and gravity.


With a few tricks it went pretty smooth
 
Majority of the frame work is tacked in place. Got a few "X" braces to put in and then its weld time.

Get some more pics posted up tomorrow.
