It does indeed look good. Great progress and good inventive problem solving as you go along.

moving along

Well Since I last posted I have attached the two Pieces togeather using a jig that represented the angle of the front of the trailer. I have done one test fit and found success is near.

I now have flipped the unit over to expose the glass side of the cover and placed two more layers of CSM where the junction of the two pieces join. .

So far I have gone through the better part of a gallon of resin and 5 yards of CSM. I think I went way to heavy on the resin. No mater its all about learning and creating.

The other evening I took some time to make up some hinges using angle aluminium. I'm going to look for a nylon ball like object to use as a bearing and perhaps use that as a part of the mechanism to compensate for the hinges on opposing plane issue. Much like a Boler door.

Any thoughts on the hinge issue.

Also I will need some mechanism to prop the cover up while camping. Any recommendations? I was thinking gas jacks but I am concerned about torquing the cover as it lifts by the uncontrollable force applied during the lift.


I am open to inspiration at this point. Any thoughts?

Richard

Looks good Richard. I do believe you'll have the strongest "boulder" guard on any TT .

I'm not sure when Bigfoot switched to gas struts, but the early 80's models used manual sliding braces with locking wingnuts. These in the link look like the same ones.

boulder guard

I think you are right boulder guard is a term that fits.

If I were to do this again I would...

Make a foam form of the entire part (both parts together) I wanted to make. I would use plastic and packing tape to make sure the foam for would pop out of the new part. I would use West System Epoxy so that there would not be the big smell that I have had to tape the garage door shut.

I would lay four layers of glass at least in quick succession in order to keep weight and time down on the project. The glass cloth would probably give a better or easier finish at the mend of the project as well.

I haven't any regrets so far. But then again I have not drilled any holes in the trailer. YET

Well last night I gel coated the under-side of the cover tonight I did the outside. Now to move the thinking parts to hinges, lifts and hold-downs.

Given the angles on the front of the trailer I think I will use Bondo to put a 3.75 mm wedge under the hinges so that they will be on a straight plane. Once I get the cover on I will have a chance to observe the action of the cover and how much room I actually left myself inside.
