1. 1st time box builder questions......

1st off, do most people use a skill saw to cut the mdf or do you use something like a table saw? My friend started making some cuts tonight with a skill saw, but he ended up short in some spots. We're wondering if lots of liquid nails will get it to seal good enough?

He is making a truck box, so the top depth is shorter than the bottom depth. How do we go about figuring how tall the front board will need to be? It'll have a 7" top depth and 17" bottom depth.

Thanks

2. a table saw is better but skill saw works just as well..... to make a straight cut with skill get some c clamps or somethign along them lines... take a straight piece of board or a long level. then mesaure from the blade to the end of the guide plate(dont know real name)and add that much and put the straight board on that line and clamp it down and start to cut....... liquid nails should feel it up but i would you silcone alot of it.......... just put all the sides expect the angled one and then just measure..... you got the math way.... but this way will be easier........ just got in not long ago real tired so i hoped this gave some help....

4. like er1kkull said it would be easier to build the box without that one side and the measure how long the front needs to be, but just in case your like me and like to put everything down on paper here is how u would do it, it's basic 8th grade geometry.

(length of the bottom - length of top)^2 + height^2

take the square root of all that and u get the length.

Of course you would have to do a few more calculations and a few angle cuts if you wanted a flush board, but for now i would just cut that piece and use a whole bunch of liquidnails or bondo to make it smooth and flush
