I offer plans for some projects and encourage purchasers to send in photos. These are shown in the 'Your Creations' tab.

My latest project

I recently moved and left my old particle board and 2x4 work table behind. I decided to made a new table using a Melamine coated sheet of MDF supported by round and square steel tubing.

YOUR Creations

The 'Your Creations' tab lists the items that people from around the world have made from my plans. You will see Marco's rendition of my Nomad bicycle camper, and many more shelters and micro boats. Definitely check this tab out!


In this tab I offer about 10 affordable build plans for the DIY'er interested in making their own micro electric or power boat or fluted plastic or foam board micro shelter. There's even plans for a dog house.
