Re: Low buck projects- Let's see 'em!

I always wanted a new rudder to replace the slab rudder that the factory built. I started with a lamination of plywood, then built a vacuum bagger and applied 3 layers of 9 oz cloth on each side. All three of the layers on each side are wrapped around the edges, making the edges 6 layers thick. I knew without the vacuum, it would be a terrible mess trying to get the heavy cloth to go around the sharp edges.

The vacuum pump is a small fridge compressor, some hose, and a mason jar. The jar is to prevent epoxy from getting into the compressor.

So far it's working. Tomorrow we will turn off the pump and check it out.

Nice! It looked like a welded seam at first. Great idea!

Re: Low buck projects- Let's see 'em!

The pump was getting a bit hot so I put a small fan on it and it stayed luke warm. I left the pump run all night.

Fresh out of the bag and after a little "deburring". Lots of fairing to do.

There seems to be nothing that butyl can not do!

Re: Low buck projects- Let's see 'em!

Nice! I have been working on a vac bag system and didn't think of an old fridge compressor. I will give it a try. I have an old freezer that is headed to the dump. Thanks!

It looks good!

Re: Low buck projects- Let's see 'em! My cheap but working fridge

I did the same with my p30, I used parts from a water cooler, including the thermostat on a 80 degree day box goes down to 37. Planning to operate the system with a 2kw inverter 240 watt panel to charge battery bank (500wh) will post back with results

Re: Low buck projects- Let's see 'em!

Replaced my companionway boards today. Lowes carries a plastic board now that is 11 inches wide and only 5/8 inch thick so it fit really well. The board was $30. The downside is they are a little heavy, but I plan to put some spare smoked acrylic in the middle one and a vent on the top one so that should help. The bottom one probably won't come out much.

Re: Low buck projects- Let's see 'em!

here's a zero dollar project. i found the bucket floating by the boat and the plexiglass in the dumpster (the treasures some people throw away!!). a hot knife and a little 5200 and now, with my "lookey-bucket" i don't have to jump in the water to check my anchor or see how vibrant the reef is before snorkelling.
