Questions about Aluminum Trim

Postby drewh1 » Fri Jan 10, 2014 4:53 pm

I am getting ready to skin my project in aluminum (build - Heart of Gold). I would like some advice about what trim to use.

I don't want to use the edging with the vinyl strip insert so I see the following options:

1 - Teardrops trailer.net has 9' sections of body edging, measures 15/16th by 1/2 in. Says it is very easy to bend. The 15/16. I like that it comes in 9' sections although it is still too short for single piece along my roof edge. the 15/16th is also a bit wide for my hatch edging.
2 - teardroptrailerparts (vintage tech) has a 7/8th by 1/4" in 8' sections that I could use everywhere including the hatch seal edge.
3 - Lil bear has a variety of edging but seems quite a bit more expensive than the other alternatives.

Also wondering if I can use flat stock aluminum edging for the bottoms or should I use the the regular edge trim with the lip overlapping the bottom edge?

I would appreciate hearing from any of you that have used these trims and get your impressions and recommendations.

Thanks,

drew.

I used a lot of flat stock that I got at a local metal distributor - it was in 20' lengths but they cut it to what I needed and sold it by the pound. I got my drip rail and 90 degree trim from a local RV dealer that does RV repair. What they didn't have in stock, they were able to order pretty quickly - it was 15 ft lengths.

My own take on it is that you need to have the lip on it and set it down over a good bead of GE Silicone II (not the first gen). I had the same problem with lengths and butt joined it and it came out fine.

Wow I had the exact same questions. You just don't know until you get some experience with it.

I liked the RV edge trim for everywhere I had to bend it. Very easy to bend. I used it for the front, roof, and galley rounded edges.

I used 1 inch angle for all the unbent pieces. Lower edge, front bottom edge. Lots of small end pieces.

I also used the 1 inch angle for around my door jam trim. Really hard to bend! Took me all day to beat each door in place with a rubber mallat. There has got to be a better solution for that!

For around the doors, I used grants T molding, that worked great and easy.

I used 3/4 butyle tape for everything except the doors. On those I used a silicone sealant. It was thinner and easier to make the doors look good. But I assume it won't last as long.

Check me build thread, lots of aluminum working pictures.

I have gotten alot of good information from your build thread John - You did an amazing amount of aluminum work and edging. The Cooler really looks great and will last for 100 years!

Ok - I ordered trim and aluminum sheets! pretty exciting place to be in my progress. i have a couple of questions.

Do I need a speed controller to use the edge trimmer in my router?

Should I use the laminate bit or a bearing edge bit?

I thought about buying a router speed control and didn't. I didn't have any problems with the speed. I've got a aluminum sheathed tongue box project in the shop right now and still no regrets.

You need a laminate trim bit with a bearing on it. I think they are only made with the bearing.

Trimming 040 aluminum is not a challenge with this system. I covered my aluminum with masking tape to avoid scratching it where the router base rode on it. You don't want to get a sharp piece of aluminum under it and drag it across the sheet.

What size and shape of aluminum trim is preferable to use for the sides of the galley lid?

I will be fiberglassing then painting my teardrop including the outside of the galley lid. I will need trim on the sides to keep rain and moisture out. I imagine a L shaped trim should be used. The side walls in the galley will be 1-1/8" thick/wide if that makes a difference in choosing the right trim.

Thanks Tony! I cut some pieces on my miter saw without a problem. I'll skip the speed controller then. I have a couple of edging bits with bearings so should be ok.

Here is the aluminum . . .s
