I have read a few threads over the years about tools and how to get them to the jobsite. As a matter of fact, there was one just a couple weeks ago.
I have the best answer to this problem. A garden cart! I saw these tool carts in Trading Spaces and finally saw a photo of one up close. Theirs is a red wagon with a wooden box on top (I always thought they were metal). I built one from a garden wagon that I bought at LoweÃ¢â‚¬â„¢s (under $80.00).
The cart is suppose to hold 1500 lbs. and its sides fold down. The great thing is the size of it. ItÃ¢â‚¬â„¢s only 2 feet wide, 4 feet long and 15 inches high. I built a box (out of scraps from the job) that takes it to 42 inches tall. For all of you lucky guys that work out of trailers, this is an easy thing to carry around. But, I work out of a van and I use a set of ramps to get it in there. It is easy to push it into any jobsite.
I am a trim carpenter and the first day with this thing I loaded it up and pulled it through soft sand and over pallets and 2 by 6Ã¢â‚¬â„¢s. It easily fits into any doorway because of the width and carries everything I need (even the chop saw).
I hope that you check out the attached photo and consider making yourself one. I have tried everything else. If you like making several trips to the truck, this isnÃ¢â‚¬â„¢t the thing.
