The DIY R/C Sailboat Project

I've been wanting to combine a few favorite hobbies, woodworking and physics, and dive head first into a project I know nothing about - sailboats. I have been thinking about dusting off the old RC gear and configuring it for small-scale sailing for a long time, so I thought I'd build a boat over the winter. There's something unbelievably rewarding about building something like this from scratch, even more so if you tackle something that you know has a significant probability of failure . This is definitely a boat that is much better built than bought... IF IT WORKS.

 

 

Rock Tumbler Sound Proof Box

The only drag with this hobby is the sound the tumbler makes for months on end. Its not really a problem for me, as the tumbler is in the shed... but I feel bad for the neighbors. There are tons of articles on sound dampening techniques and Ive tried several, including a plywood box covered with carpet samples. I like the idea of using styrofoam insulation because it easy to work with, has minimal resonance across all audio frequencies, and its non-flamible.

After running a tumbler for over a year, practically non-stop, I got to see where the wear points and heating issues were coming from. I sat down with some paper and drew up what my dream tumbler would be. Some of the specifications and major improvements over my Harbor Freight 6lbs model would be:

Continuous running
All bearings to be replace nylon bushings
Fan cooled
Adjustable roller spans
Sound-dampening enclosure 

DIY golf Stimpmeter

Make your own stimpmeter

DIY Stimpmeter
I had been playng golf for about twenty years but just began regular putting practice when I joined my first men's club last year. Between the two public courses that I sneak out to for putting practice,  one feels like a shag carpet and the other feels like glass. I've been seeing signs reading   "Current Stimp xx.x feet" for years and decided to build my own Stimpmeter.
