Cut 15 top boards 5 ft. long and rip them to 3 in. wide with a table saw so the top will glue up flat without the typical rounded edges of 2x4s. For the leg slot, cut two of the top boards into three pieces: a 39-in. middle piece and two 7-in. end pieces. Glue and screw the top together, one board at a time, with 3-in. deck screws, keeping the ripped edge facing up and level with the adjoining boards. Use a corded drill so there’s plenty of oomph to drive each screw below the surface. Note that the third glue-up from each end is where each leg notch is inserted. You can also create a nifty tool tray in the top by notching the three top pieces with a jigsaw. Clamp every 8 in. or so before driving in the 3-in.deck screws. Predrill the screw holes near the ends to prevent splitting. When you’re screwing on the 7-in. long 2x4s to create the leg slots, use a scrap piece of 2×4 as a spacer.
If you want to spend as little as possible on a vent fan, the Fan-Tastic Vent 1200 (about $130) is your best bet. This fan has three speeds and manual controls, and it has the same quiet operation and energy efficiency of Fan-Tastic’s other fans. If you find that you need to use it while it’s raining, it’s easy to add on an Ultra-Beeze Vent Cover later on.
Great instructional! I built the bed of my 92′ Toyota pickup ext. cab the same way you did. I did some hard searching and found this camp pad, which literally fits the 40″ wide sleeping space perfectly. A few different mats from Exped will fit, but here’s the one I bought. Just thought you might like to know there’s an inflatable duo sleeping pad out there that works for your setup!

I save all my back issues of The Family Handyman magazine and love the projects and repair tips. The trouble is, I’m not always ready to do the project when the issue arrives. To make my favorite articles easy to find at a later date, I put a stick-on label on the cover and then add notes for easy reference when the time comes to do the job. — Willie Schreiber. Plus: Check out this small workshop storage solution.
At some point in the process of starting a small business, it’s pretty much guaranteed that you will hear the following statistics (or variations thereof): 25% of new small businesses close their doors within the first year and 60% are gone within three years. The exact numbers here may vary, but the message is all the same: be afraid, be very afraid!
Use the scrap piece of plywood to map out the angle for the speaker stand legs. Decide the height you want for the base of the speakers, and make a mark on the plywood (32 in. for us). Mark the depth of the speaker (13 in.). Lay the 1x4 board assembly on the plywood, lining it up with both the corner of the plywood and the 13 in. mark from the edge. Scribe along the 1x4 board assembly, take the assembly away, and find your angle with a protractor or speed square (17 degrees for us). Cut that angle onto one end of the 1x4 board assembly.
We do not recommend using Reflectix to insulate your walls or ceiling. Without an air gap, the R-value of Reflectix is about R-1. Even if you have the recommended ¾” air gap next to the Reflectix, the R-value per inch is less than R-3. There are much more efficient and cost-effective insulation materials out there for these purposes - you’ll be better off filling the space with rigid foam board.
Non-Standard Miter Slots - This one is a downer.  One of the primary advantages of having a table saw is access to jigs that expand the saws functionality.  This is a major issue if you plan on buying after market jigs.  Given that we are limiting the cost of this buildout to $500, I am guessing that after market jigs are probably low on the priority list.  Your going to want jigs once you start researching what they enable you to do, my advice is to build your own - there are plenty of plans online.
