Steel or Aluminium

scottypaul

10 gauge wall thickness on ally hollow section would be plenty strong if i was using steel i would only want 16swg on wall for similar.

Hello K9D,

my query was put simply because I'd assumed that you had the method of construction finalised before asking your question. It seems I was mistaken. If you read my original post I stated that the strength was down to section; of course for the same section steel is normally stronger than the usual alloys of aluminium, as Paul's last post clarifies.

Hi Alec,

Another reason for asking the question is that others may find this thread useful if they wish to undertake a similar project. I find this forum to be a good source of information so if I can give something back it seems only fair.

I found similar issues. The Unistrut helped there for the passenger seat as I could just slide it in toward the centre a bit (plus as I shortened but retained the original runners I have the luxury of it moving fore and aft as well, like the drivers seat does).

The drivers seat though fouls the drivers door and is a tight squeeze to get it to rotate 90 degrees (it can't go further around cos the steering wheel gets in the way of the backrest, and of course moving it out of line with the pedals ain't an option). I can make it easier to rotate by removing the RH armrest, but I like using the armrest when on the M-way so I've decided put up with it being a tad tight when I want to turn it.

The only bit thats a bit of a loss is that when I binned the original (horrible and hard as a brick) LDV Drivers seat I had to sacrifice the height adjustment feature. As it is its ok for me, but I think a very tall driver would have liked the option to drop the seat a bit lower for better visibility.

Did you try pushing the seat as far back as possible before turning?

Yes, but there's not quite enough room. Also behind the drivers seat is the 'sofa' that faces sideways to the side sliding door, and that extends into a bed.

So, even if the seat could slide back far enough (it can't) to clear the steering wheel it'd be up tight against that.

Its not an issue though, as with the drivers at 90 degrees it lines up with the sofa, while the passenger seat can fully 360 so can be rotated to face fully backwards. This creates a sort of L shaped seating position which seats 4 comfortably and 5 at a squeeze (more than 2 only happens when there's 'visitors' as
its only a 2-berth layout.

The steering wheel isn't too bad - I just lean my arm on it and its comfy enough when turned thru 90 deg. Overall the layout works very nicely for us.

I just took delivery of a new clear dome skylight as I'd like more natural light in the living space, esp. over the galley. So next scary thing for me is to take the plunge and chop a big hole in me roof :danger::help::scared::scared::scared:

Bit of a sweaty palm moment, my suggestion is measure twice, then measure again then go for it. It will make a great difference to the van I'm sure.
Good Luck

what size skylight ?.if it's a 40x40 or 50x50mm,then cut a bit of card or ply that exact size first. you can then position this on the roof nice and square,before drawing round it and cutting

Its an MPK 280 x 280 Rooflight c/w flynet and clear dome Nigel.

I would like to position it over the kitchen area which is a bit gloomy without lighting on as its away from the windows - hence selecting a small size with clear dome so it can fit in the roof space above the galley and in between the outer wall and the inside wall to the cloakroom.

I also wanted to make sure it was compact enough to easily fit between the steel roof joists that loop side-to-side under the glassfibre Hi-Top. I know where one runs across above inside the existing insulation and roof cladding so plan to move a couple of inches away from that and then should be well clear of any other structural bits.

I have never fitted any windows or rooflights myself before, so had the idea to use the inner / lower section as the template to cut the hole to (there's no 'destructions' or fitting screws with it btw, but it looks not unlike fitting a Cat Flap!) then use Sikkaflex around the inside upper frame base of the Outer (there's a sort of detent all the way around that looks like its there to be filled with sticky fixing gloop!).

Then, I thought to fit and screw the inner into place to clamp it all together with the (unsupplied) screws, and then add more Sikkaflex around the outside edge of the Upper external section for added water ingress protection paranoia?

If anything I suggested there sounds over-simplistic and/or just plain dumb, please feel free to enlighten me!

Don't do what I did many years ago on a Vauxhall Chevette when fitting a sun roof, I made a paper template, I had to use two pieces of paper because of the size, cut a hole in the roof, dropped the sun roof in and straight through. I had drawn around the outside of the sun roof and no the inner part that I should have done :(.
At least it was only a Vauxhall :)

the sizes of windows and hatches is the aperture size ie 280x280 is the size of the hole ,and Wint is right you should use a non-setting mastic,or mastic tape,or both .
mark the hole,then mask off round it with cardboard. whether you use a jigsaw or disc cutter,hot swarf will embed itself in the surrounding paintwork ,then rust
i' d use a disc cutter with a 1mm thick blade

I just ordered some of the 32mm mastic strip, and a tube of non- setting mastic gloop for good measure.

Ive also found a leak which I suspect is coming through the awning mounting holes, so this stuff might well prove handy for tackling that at the same time

I shall have to get stuck in as soon as opportunity presents!

I have now converted the wooden mock ups into steel

View attachment 27619

Next thing is to drill the holes for the seat rails and then fit the seats, I will be painting the steel and fitting end caps to make it look tidier.

Cheers.

I'm pleased with them its not a perfect job on the colour change but as an ex printer I'm a fussy bugger. :)

the other thing you can do is weld a set of runners on the floor box going left to right, then weld the normal ones across them on top at 90 deg so if seat is to close to side or wheel you can slide it just about any way you wish.
Also will line up with pedals better.
