This is heavy, hard material. It's like working with very hard oak. Speeds + feeds were critical to avoid stalling the saw or popping the breaker. I had to sharpen my saw, mid-project.
The shiny bits are metal. They are non-magnetic, so they're most likely aluminum. There were loose bits of unground plastic sheeting inside the material. And, it wasn't dimensionally consistent. The width ranged from 5-1/4" to 5-5/8".
Still, I'm pleased with the result and these should last as long as the trailer.
The next step is to clamp, drill, counter-bore, and bolt the bunks to the trailer.
Note: Photobucket is still screwed up. This photo failed to upload on the first 2 attempts and I had to go through the back door to copy the link. Only 11 minutes to get this photo posted here.
Mark, the side bunks were made from a type of urethane rubber material. It was from the scrap bin where I had worked. I can't help you beyond that. They have stood up well to the environment. I suppose they have met the "success criteria", unlike so many material things we purchase.
For example, windshield wipers have the success criteria built right into the name. However, the engineers forgot that we get sub-zero temperatures 4-5 months of the year. Wipers meet the success criteria 65% of the time.
The weather is to be nice tomorrow. Sapphire should be coming out of the lake. Her sailing season will be over. Bring on the winter projects.
Sapphire went for her last sail of the season yesterday. The conditions were rather "pedestrian", very unspectacular. The temperature was unseasonably warm, so that made it very comfortable.
She is still swinging from her anchor this morning, but the sails have been fold' and rolled, the boom is put away and the rudder is in winter storage. If the rain stops, I'll complete the trailer project and haul Sapphire out of The Maz.
The season is over. Do us proud, Bob. Show us some late-season sailing pix.
PS: After 10 minutes of "Uploading" at PhotoBucket, I switched over to TinyPic. You'd be wise to back-up anything you have been saving at PhotoBucket and move it to a hard drive. "The Cloud" does not have a silver lining.
