interesting little tidbit before i get to more pictures, the cabinet weighs ~100 lbs on its own, and the cart is listed at 120 lbs, so combined weight before tools is around 220 lbs. know that before you do this mod, and be ready to sling not only the additonal weight, but the extra 18" off the side of your cart!
now, onto the 'lift kit'.
as i said before, getting the ~33 inch cabinet to match the height of the 41.25 inch cart isnt an easy task. especially if you want it to look clean. at this point, my need for the cart out-weighed my want for it to be as pretty as possible, so in a pinch, the 2x6's work just fine. this isnt my permanent solution, but it does work for now, rather nicely.
something else that should be considered is that unless you get your lumber raw, the actual measurements of a 2x4 or 2x6 is smaller than the true 2x4 or 2x6 label. so YES stacking 3 2x6's sounds like it would give you a 6 inch lift where you only need 4.5, but in reality you only get 4.5 by stacking the lumber.
now that the lumber lesson is out of the way, on with the pics!
the inside edge /bottom of the cab:
the front edge:
the outer edge:
i did not get much in the way of actual build pics of the block. but its pretty self explanitory what i did to make it. 3 chunks of 2x6" cut to 17" (roughly) stacked and screwed together, then drilled holes in both the block and bottom outer edge of the cabinet to match the casters, and sent bolts through to hold it all together. the trick was in all the afforementioned measurements, and the drilling holes in the cabinet. THAT THING IS RUGGED to say the least. i had to not only drill the holes, but cut out sections of the inside of the box to allow for access to the bolts. yes. i said CUT OUT sections. adding this box was already not for the timid, but if you're the least bit against breaking out the cut off wheel on your brand new box, than throw some big heavy bricks in the bottom of your cart, hang the cab and call it a day, because adding the casters was a job and a half.
so here it is, all mounted up to the cart at work. the last bit of drilling you have to do to mount it is marking and drilling the holes where the bottom of the cab meets the bottom shelf of the cart, then just hang it up top and bolt it to the bottom.
oh yeah, and did i mention, i modded the lid of the cart to close?? more on that in the next post.
