There's some things you need to know about that Harbor Freight link. I have nine of these boxes. They are copies of the famous machinist's boxes from 100 years ago (still being made, by the way- Gestner
http://www.mscdirect.com/ProductCompari ... 7,89759948 $2400), and the wood appears to be light teak. The floors are all cardboard, flocked with Kelly green fuzz. I have two of the big ones that this link goes to, four of the middle size, two of the smalls, and one very small, a little bigger than a shoebox. They do not have enough drawer depth for most slot cars. The middle size barely has enough room for slot cars in the drawers. They get heavy fast if you use them for what they are intended, and the cardboard floors won't last a day with machinist's bits, cutters, mill ends, calipers, rests, etc, etc, etc. But I will say, as a stationary tool box for slot car tools, they are hard to beat. I use one of the big ones (the link goes to it), for most of my slot car hand tools, lubricants, tiny detail parts, and stuff. I also have to say that when I bought mine, the big ones were $40, the middle ones were $25, and the small ones $10. My smallest one was bought later. Mine came from a woodworking tools catalog online, and that outfit was bought by another woodworking outfit. It was only about 7 years ago, so HF is screwing people with that claim of retail price. It is doubtful that the sale price in the link is as cheap as you can get them.
There are several very fine wood boxes made by slot car guys. They are quite easy to build, and I would be surpised if there weren't some plans out there on the net. But lots of guys make them, and some of them are fantastic. One of our guys builds them from time to time, and his are very similar to one of the ones I have seen Harry use in pictures on HRW. You should have no trouble finding them for $100 or less, even $50 for small ones.
