Two things I would consider.
1. I'd wire it and put an extension cord on it so I could have power if needed, or roll up the cord if not.
'
2. I'd put a Randy guard on it so he would have to leave it alone. Wouldn't want it to end up in his "Lair"

 

Randy guard, eh? I like it!

 

Take Gary's idea with the extension cord and build a manual winding reel for it so you don't have to wind it up over one arm like I do right now. Plug one end into a surge protector mounted on the cart and pull out the other end to the wall outlet. Another thing, beer holder.

 

Also, if it were mine, I'd probably use it for glue-ups a lot. I'd have a drawer for clamps, rack on one end for bar clamps, and a specific spot on the end for glue.

 

I'm throwing ideas, Stumpy. Maybe a torsion box top for super solid/flat surface

 

If it's going to be used as an assembly bench then:
shorter than a normal bench but not too much.
storage for clamps on the side and some grooves or something so they can be set up on top with one hand. Or built-in clamps that flip up when needed
some flip-out holders for chisels, scrapers, rags, whatever the clean-up tool of choice is.
A holster for a cordless drill or screwdriver for those who like to use screws.
Or a place underneath for the air tank and a hook on the side for those who like Norm (a little glue and we'll just finish it off with some brad nails to hold it in place. pfffft pffft pffft.)
A replacable drawer or box that can be configured to the task at hand, and a small separate storage system for the spare boxes.

 

I actually think I'm going to use one of these. They're a little pricey, but super flat, thick and built in T-Tracks with intersections. That would make it useful for all sorts of stuff.

 

Well, here's another. I've often thought of building one that could be used as an extension to the table saw that had spots for the blades, wrenches, various …... can't think of the word….throat plates…. you know what I mean.

 

OK, my last input. I'm probably a cheapskate but, $230 just for the top would stop me

 

No, that doesn't make you a cheapskate. I think it's expensive too. I'm getting a deal on it.

 

Well, just be sure to keep the Randy guard in it

 

I like Greg's idea at http://lumberjocks.com/projects/19642 You could put the T-tracks in it.

Keep meaning to make me one some day.

 

Surge bar. Like clamps one can never have to many outlets. This may sound stupid but my shop cart is heavy…really heavy (layers of 3/4 MDF on top of cabinets from made from thick laminated composite). If I lock the casters it aint going anywhere. Its weight lets me clamp bench top tools to it (dampening vibration). Anyway I have this old fence from a buddy who upgraded his table saws fence to a really long Excalibur model and I have thought about mounting the fence to the cart and putting some of those adjustable shelf brackets on the side. This would allow me to mount different tools on the side and use the fence as a fence (for my spindle sander or router table for example) or as an easily adjustable stop for the bench top tools.

 

I would make one that can double as an outfeed table and have a downdraft sanding surface built in to the top.

 

That Rockler table-top is way TOO nice! Too nice to mess up with dry wall screws. I would frame the table-top so that it would LIFT OFF. A sturdy,rolling cabinet with inter-change-able, lift-off / drop-on table-tops.

1) Rockler T-track table-top- for the well-planned,perfectly-executed jobs.

2) 3/4" plywood table-top - you can drywall-screw a jig onto it, dig a groove in it with a wen allsaw, write on it with a sanford ultra-fine point sharpie,spray paint all over it, and throw it away after you've destroyed it.

 

As I've got one and have had it for a while,,,

What I like about mine…
-cabinet maker workbench type top, but made of pine. When I'm assembling I'd rather the bench gets dinged not the project. Top has hole for bench dogs
-face vise
-4" swivel locking wheels
-good working height (for me at least) about an inch short of table saw so I can use as extension and for planing and assembly
-shelves for tools

What I'd like to add or change
-more bench dog holes. The ones I put are frequently too far apart
-better shelves specifically for holding tools and such I am working with at the time. I already have readily available drawers and such for sander, sandpaper, clamps, etc so probably pull out shelf to hold those tools I am using for that particular project or phase
-wired for power. Not really an issue as I have a 50' reel extension hanging from the rafters of my shop. Very handy.

 

I built my shop table with a few things I strongly suggest:

1) Vacuum build in.
2) Small air compressor for dust offs, and using nail and pin guns
3) Power strip with an extension cord so I can plug in the five or six hand tools I need (ROS, Jigsaw, Biscuit Jointer, etc)
4) Rather than putting tracks in my table top, I cut several holes in a piece of 1×4, then cut it in half. I connect each half with dowels on either side of the table. With these I can rest eight pipe clamps across the table top without touching the table, and with enough room to crank the handles. I use foam pipe insulation to ensure the black pipe doesn't mar the item I'm clamping.
5) Finally, I built a tool rest for a couple squares and one that holds two drill drivers. I love having them close at hand when needed.
6) It's on wheels! Need the mobility.

anyway, just some things that work great for me. I'm really looking forward to seeing what you come up with.

 

Having thought about this before, I think any practical workshop cart will have to be either more of a (1) TOOL CART (hand tools/power/pneunatic tools), or (2) ASSEMBLY CART (clamps, glues, finishing products, rags). Of course, it can be both - I'm just saying it will likely be more of one than the other, depending on one's workshop setup - as shown below (from some previously googled pics).

BTW, if I were to make a power tool cart, I'd have all the tools plugged into the cart's power bar(s) at all times - and put an end to unplugging/plugging-in/wrapping up cords forever!

 

I am working on a heavily modified version of this.
http://lumberjocks.com/projects/80953
I ordered the plans form the gentleman online, they arrived via email promptly and the customer service was excellent. I do plan to order the rest of the guys plans too.

Im telling you guys this cart is amazing. Ill be adding my own ideas of course but I could never have designed the basic cart.

 

maybe I am the odd ball here, but I like my tables a little bigger. Mine is close to the ones pictured, but has a 4'x6' torsion box on top. so in a line I have a PM66 (32"x7'), and then a 4'x7' runoff table, then the assembly table. and they are all in plane with each other. When I am building something I roll out the table, and when it is not needed I push it back, move the jointer and planer and I can park my truck in there when needed. Normally I am against parking in the shop, but I was working out of town (6 10's with a 70 mile drive each way) and I will be darned if I was scraping windows @ 3:30 am. now that I am back in town the truck is in the drive where it belongs.

 

To make the work table really efficient, 3/4 inch holes drilled all over it and a series of 1 1/4 slots routed into the top will let the user use all sorts of clamps to hold "stuff" in place. T tracks would also make the table that much better.

I used some of these on my new drill press table.

I really like this project posted by fellow LJ toddbeaulieu.

 

In the category of little details, I would have
-small whisk broom hanging from a hook

small magnetic bowl recessed in the top. I bought two such bowls at an auto shop and LOVE them.

 

I would include a space for shop necessities….
band aides, gauze bandages and tourniquets!!!
Oh yeah, and a fridge for cold ones!!!

Seriously….
I would incorporate:
small compressor
Shop-vac
power strip
Dispenser/holder for a roll of paper for glue-ups
Bar/pipe clamp panel clamping ability
Bench/end vise
Dog holes/bench dogs/fold fasts
A swing arm task lighting

I'd leave off the "Randy Guard", as I would like to be able to use it!!!

 

Take the ones you posted and cross breed them with this. Then you have something "mobile" Those little crappy rollers are cute on concrete. What if you want that "mobile bench" outside to install some gutters or windows or do a roof repair ?
What if you're a farmer or grease monkey with a gravel driveway ? With your "mobile benches" it becomes forklift time.

 

What if you want to put an Allison transmission on it ? Those match stick chicken legs and office chair wheels aint gonna get it ;-)
