Unfortunately I don't know of the FSM issue you are referring to but I have built my own hobby work bench from scratch and can offer some quick tips.
Simple desk design:
-Use kitchen counter top.
-Whatever wood you want for the legs (I suggest 2''x2''), just measure how high you want your work space and cut the legs to that length.
-Use triangle blocks with a 90 degree cut for the inside part of the legs (8 blocks total) to reinforce the legs.
Eg, --- being top of desk, " | " being the leg and X being where the block goes.
----------------
| X
|
|
Extra options would be:
-Pull out tray under the desk in a location of your choice.
I used kitchen drawer rollers and a narrow piece of kitchen counter top. Just attach it to two rectangle boards (~3/8 thick, maybe less) cut to the height you want between the tray and the work surface above. To lock in place i use a small dead bolt (you know, the ones you see on fence gates) that fit into a hole I drilled into the drawer slider.
-Shelf. Wall mounted or mounted to the desk
Stupid simple to make, just cut some rectangle boards (~3/4 thick) to the height and depth your want and put more rectangle boards in between to make the shelf spaces you want. Small doors (using kitchen cabinet hinges) can be used as well.Don't forget to attach it to something. -edit- Use the tool called a "Square", this is not optional if you make this yourself.
-Drawers. NOT easy to make, I recommend buying if interested.
Buy or make from scratch, I recommend have it as a detached unit. This makes the work bench easier to move as well as allow you to customize your space better.
Notes:
- I recommend kitchen counter top because it is VERY durable and often a smooth flat surface to work on. Stores that go through a lot of it may offer discount prices on short lengths. It also has a nice lip on the back to prevent stuff from falling behind your desk. Full price is by the foot and not cheap though.
-Use screws. Make sure they are long enough to get at least 1/2 inch into the wood blow that you are screwing into.
-To attach the legs & triangle bracing blocks I suggest drilling straight down and "counter sinking" the holes. Counter sinking means creating a space for the screw head to go into so it is flush with the work surface. You can simply use a larger drill bit or you can buy the proper bit. Once flush you can fill the hole with putty or epoxy to make it a smooth surface.
-If you make a pull out tray, be VERY careful not to get sawdust or metal shaving (if you have to drill in some metal) into the inner workings the the drawer sliders.
-To make look more pretty you can get different woods (eg, oak) and / or stain/varathane/paint it.
-Edit- Pre drill, pre drill, pre drill your holes for the screws. Did I mention to pre drill? The right size drill bit is one that will cover the "shaft" but not the "threads" of the screw you will be using when both are lined up with the drill bit ontop of the screw (when eye balling before drilling)
Can't help on the spray boot though, sry.
