More questions! Side Boards and PVC Marks

Post by jjb on Wed 12 Jun 2013, 10:27 pm

Hello,
 Final questions of the night I hope! So I've been to see the destiny and have a question re the end boards by the beds (the ones that raise up to support the roof, the laminated wood appears to be breaking off the ply and feels a bit spongy on one  side. Are these easy enough to replace ? They seem to be riveted on.

Secondly the pvc has dark streaks in certain places and this appears to be inside the pvc (it almost looks like damp has got inside the material) the walls aren't double skinned and it doesn't seem to wipe off when you clean on either the inside or outside. Has anyone ever seen anything like this before and can it be fixed?

thanks

 Isn't the laminated wood by definition ply? You mean the ply inner walls to the outer left of the higher bed and outer right of the lower bed when viewed from the door?
 Should just be a drill out of the pop rivet heads and a punch through of the residual rivet. Then replace the panel. You may need specialist caravan dealers for ply that thin and light. Helen has noted one somewhere.

 I've got a light brown stain on a newly acquired awning not sure if it will clean, not sure about streaks. If the usual fails try asking Ian, Mike Channel Island Covers or anyone who deals in curtainsider trailers.

Could the damp in the PVC have rotted the ply

The sideboards are indeed thin plywood with a vinyl finish and are commonly available for caravans and motorhomes and is called 'wallboard'.  I had to replace one but Ian at Riva told me the original manufacturer was no longer in business.  I used Magnum Motorhomes (on the internet) and can confirm that 'Balboa' is a good match for our 2006 Riva.  I had a number of samples off them and this one was very close to the original.  The pattern should be good for older Dandy's but if in doubt ask for a sample.

Drill out the rivets from the sideboard hinges and remove the sideboard complete with its metal frame.  Drill out all the rivets and remove the old wood.  It's a good idea to note/photo/sketch things as some of the rivet positions also have p-clips for the roof liner.

I used the old board as a template for the new one and marked out all the rivet positions like this.  Cut the wallboard to size and drill out all the holes through it for the rivets. (holes where p clips and hinges go are a larger diameter).  Rivet the wallboard to the metal frame ensuring the p clips are put back in the right place.

In the middle of the wallboard are four blue buttons that are riveted into place.  I found them tricky as you need to use extra long rivets and rivet from the inside whilst holding the button and a washer outside.

Once it's all back together get someone to help hold it in place and rivet the hinges back to the bed.

For reference (from my original shopping list) the small rivets are 3.2mm diameter x 10mm length.  The p clips are held in with 4.8mm diameter x 12mm rivets and the blue buttons need 4.8mm diameter x 20mm rivets plus washers.

Thanks. Nice touch mentioning the size of the small rivets. I thought everything on a Dandy was riveted in place with 4.8mm rivets.

 If any of the hinges break while doing this watch out for replacements from Ian.

 I got some replacements and either the current hinges have in line rivet holes and the ones they replaced were offset or vice versa so do check.

Do the rivets need to be made of anything special like aluminium or stainless steel etc.

The rivets are all aluminium.  Sometimes owners have replaced the rivets that attach the hinge plate to the bed frame with stainless steel ones.  The original rivets tend to shear and if not corrected the bed could fall off.

On the subject of rivets, where is the best place to find a good range of sizes available in sensibly small quantities for DIY purposes?

B&Q usually have a range of sizes in small packs by Stanley .......not cheap:shock:
e-Bay usually cheap but larger quantities

I get my 4.8x12mm from the "Super bargain megastore" in Warrington, £1 for a large bag, quantity not stated but I would guess about 100 Very Happy , also one of the bubble mutipack cards of various sizes at the same price. It's one of those shops run by sub-continentals that sells just about everything. You may have one nearby Smile

I have the Screwfix pack which covers most purposes but wanted a few other sizes for the blue buttons etc. and was only finding packs of 500 or 1000. Looks like Toolstation is the place to go.

I did have some excellent really heavy duty ones in my toolbox that have been there since I was an apprentice a very very long time ago. Just shows that if you keep something for long enough you'll fine a use for it! I used the last of them to rivet the mixing bowl to the garage door (as discussed in another thread Laughing )

Do you not have an engineering merchant or similar near you?
When living in Bradford I would have used [You must be registered and logged in to see this link.] in Bolton or Wigan [You must be registered and logged in to see this link.] possibly [You must be registered and logged in to see this link.] nationally.
I'm actually disappointed to see that BBN, and Brabbin and Rudd have gone on line. In the case of Brabbin and Rudd only just, products are not listed yet. Prices tend to be cheaper in the shop (Lots of things are not cheaper on the internet) and if you don't know quite what you are doing these people will help.
N.B. This is the polar opposite of going into B&Q: 1) They are cheap. 2) The staff actually know what the stuff does. 3) Most of them will help and not sell you stuff you don't need.
 So poor to see that almost all rivets listed are aluminium. If you went into the shop they would caution you that aluminium is sufficient for holding light ply fittings but stainless would be good for heavy hinges. They would also tell you that you need Lazy Tongs to rivet stainless steel rivets.

 It will be cheap to buy fastenings but if you find you need tools these will not be the place for cheap tools. They will tend to have high quality products meant for industrial or commercial use.

Sorry Peridot I'm replying to your question but extending it for those who are used to getting ripped off at B&Q and the likes. Actually surprised that you don't have a favourite engineering merchant locally, you sounded to be that sort of person.

Until fairly recently I have always either worked directly in, or had ready access to, engineering workshops with well-equipped stores and boy do I miss them now Crying or Very sad

I do need to find some good local suppliers, I'm sure there are a few around.

We are lucky where we are there is a company a few miles down the road which when we were rebuilding Phoenix we could go to and buy any amount of any size and type of rivets we needed. Also nuts and bolts. We don't know if they do a postal service, but you could give them a ring and ask.
