This is my first boat building project and ownership. The last boat I was on was a Fleet type WWII submarine, so this is really a new deal to me. I made the decision to build MT from research on the Internet when Common Sense Designs was still in business. I am afraid I may be partly responsible for Bernie going out of business because I called him so often with too many questions.
The blueprints from Phil Bolger are not long on details, so much study was necessary for me because I am a novice. I had no idea what the names of boat parts were and had to learn them as I built each one. There is some room for individual interpretation of how the boat looks, but I am happy I followed most of the plans closely.
It took three months of studying the plans before I felt ready to buy materials and cut wood. The actual construction began in May, 1999.
I chose MDO plywood because of cost and availability here in Idaho. All my research indicated it would be as serviceable as Marine plywood if I double-coated it with epoxy prior to painting. The finish paint coat looks fantastic, so the combination seems to have worked for looks anyway.

I won't know for several seasons about durability. System Three Epoxy Systems in Seattle was my source for epoxy, wood flour, phenolic micro balloons, measuring devices, brushes, fiberglass cloth, and tape, etc.  It is a great company to work with and more reasonably priced than some other popular sources. My local lumberyard picked up the MDO out of Oregon. I used mostly 1/2", some 3/8", and some 5/16". I chose Fisheries Supply out of Seattle for paint, hardware, etc., as well as West Marine in California. Laird Plastics in Salt Lake City is supplying the Lexan for windows. I used a local tool supply company for stainless steel screws.

Bulkhead C and D in place.

I have a fairly well equipped shop, so this was not a single car garage project. Once I turned the hull over, I had to move it to my carport and have 2 1/2 inches of heighth clearance to get it out after construction. The hull sits on a piece of industrial grade one inch particle board with 3/4" pipes underneath it to roll it outside.
I am making a dry dock with laminated 2 x 8's with a 9" span to put it on prior to lowering it down on the trailer.  I bought a stripped down, used EZ-Loader trailer for $150.00 and built the bunks to suit the MT hull configuration. I built the lower ones first, then will put the boat on the trailer and custom fit the outer hull and side restraints. I am not enough of an engineer to build them ahead of time. Once I see what I need, I can build most anything, but have no skill for anticipating measurements. So far, I have about 1500 hours in this boat and do not regret one hour. I did get a little (okay, a lot) tired of sanding.
Here is the building process from beginning to present January 2000 (the weather won't let me out of the carport), with some pictures and brief comments. I am happy to visit with anyone who would like more detailed information. Without people like Brent in New Jersey, I would have been lost.

Phenolic microballoons for fairing material.

He purchased the plans and built a model, and had thought the process through much more thoroughly than I did. I owe him a debt of gratitude. Phil Bolger is also available by fax or mail. There were a couple of other builders I found on the net, but only one would respond. The plan is to move outside, weather permitting, and on to the trailer in February. Then mounting the 40 hp 1997 Mercury 2 stroke, 4 cylinder oil injected motor.
