What a CF should NOT look like

As the weather forcast is good for the next few days I decided it's time to decide the fate of my CF. I decided to remove part of the coachbuilt side panel. What I found didn't suprise me but did turn out to be worse than I expected. Okay, I knew the frame was 'past it's best' but there was worse to come. The floor under the water tank is totally rotten. Next move is to rip out the tank and see just how bad the floor is. If it's too bad then the old girl will be off to the camp site in the sky. If that's the case then this might turn out to be a very short blog!

I've just taken the water tank out. Floor is really spongy below it. I've tacked the side panel back on for the night. I've been called into work for a few hours tomorrow but hopefully I can give the rest of the floor a good look over tomorrow and make my decision.

Why not buy a new camper section and graft it onto your Beddy .

Judging by the design of the construction framework, it isn't exactly high tech. As for plywood, cut out the bad, do a half lap on the remaining sound plywood and epoxy glue new plywood in to make sound. Epoxy the cut edges of all plywood to prevent water ingress. Plywood rots from the edge not the face as there is always end grain showing on an edge. Seal the edge, no more rot!

Not really an option due to lack of space/time etc

I'll take a good look tommorrow to see how much, if any, good wood there is left. Half lap? I'm assuming split the ply to half thickness on both good old wood and new, overlap the two at the join? Overlap by how much ? What would you recomend for the epoxy and where can I get it?

Not so clued up on the best epoxy, but I thoroughly recommend Sikaflex 221 for sealing panels and seams. I have been using it to re-waterproof my Bedouin before I sell her, and the stuff is marvelous. Much better than any other sealant I have used, it is like a bloody strong adhesive AND sealant in one. cut all the wood out above the cab and replaced it, also the nearside wall from cab - habitation area. The seal is much better than the original.

Hi Colin, if you can find some sound plywood, a half lap of between 1" and 1.5" should be sufficient. Use West System epoxy with a sprinkling of silica in the mix ( also part of the West System range ) otherwise the epoxy will run out of the joints like water. You need a consistency of mayonnaise then it will ooze out of the joint, filling any gaps in the joint. To protect the edges of the plywood, paint on the Epoxy with only a small amount of silica in the mix. When Epoxy dries it is 100% waterproof, unlike polyester resin ( GRP ) which isn't.

Axminster Power Tools supply West System Epoxy by mail order, they are a good firm that I have dealt with for years. Just do a Web search. Kits come in various sizes, it just depends on how much you need to do.

I have used West System Epoxy for over 30 years, building and repairing boats, both of timber and GRP it is a very versatile product.

I reckon about 20% of the wooden frame I stripped out wasn't rotten but there were no whole pieces in tact (aside from the bits touching the top of the cab as they are out of the weather. I would surprised if any untouched cf motorhome would be free from wood rot.

Of the three CF`s I`ve owned, none of them were free from rot. It seems that cost was the driving force and no preservative was used for the timber. Do any of you think of protection when restoring? My misses used to enjoy the smell of creosote on all the soft furnishings and bedding (NOT), so that may be the answer to no paint etc on the timber. By the way Colin,---- make the bed before any more pics please.

Yes, that is correct. All new timber used in rebuilding or repairing coachbuilt motor homes should either be Tanalised (pressure treated with preservative) or given a good dose of clear wood preservative like Cuprinol.

Obviously, in the original construction process the manufacturers never dreamt that their creations would still be about some thirty or more years later!
