take your time with the skinning and make sure you get the depron over curved before you fit it.

So the skinning is a bit challenging, I only have foam safe Cyno, I have scoured all of the hardware stores looking for foam safe adhesive but no luck so things are going slowly, will hopefully make some progress this weekend.

I get my UHU Por from Ebay.......

An alternative is Evostick Carpet spray adhesive - other brands might be ok too

will go and have a look at the carpet shops. problem with Ebay is that the post normally costs more than the product to send Swaziland.

The carpet spray glue you want is the one designed to glue foam underlay - its a contact adhesive - but spray outside as it seems to go everywhere - its great for the inside of wingskins but I think you would need to sprap into a cup then smear on to the ribs and spars

Success. Went to see a mate who does upholstery. Managed to aquire about 350 ml of contact adhesive. Will have to make up a foam brush of sorts but a step I'm the right direction

Before you go near your model with it TEST it on some scrap Depron - slap some on and leave it for at least 30 mins to check its not going to eat the foam..... same goes for any new glue....

Once bitten twice shy

PS want to buy some molten depron modern art?

Thanks Dave. I am quite confident it will be ok as they bring it in specifically for foam but I had intended to do a test. That's why I love this forum. Everyone always looking out for each other. Molten depron art, hmm do you ship to swaziland.

Hey Guys, so have done some skinning with using contact glue, firstly had to remove some of the skin that I had put on with Cyno, fortunately no damage was done. So lots of learning done and things to remember for next time. Have put some filler on that need a good rub down.

Looks like you are getting into the swing of this Depron stuff, thats looking very good

What are you going to cover the skin with? Water Based Pu, glass tissue, paper or something else?

Some of the lines are a bit out, will make sure i oversize the formers a bit next time to give some shaping room. i think i will just paint this one with some acrylic but haven’t put to much thought into it yet, my main purpose for this build is to see if I can attach the wing to the fuselage properly and get it flying nicely.

So I will go with the dowels through the fuselage but im not sure I like the method on the plan for securing the wing. My concern is that it may compress the fuselage to much unless I fit a whole lot of ply .

i would fit two tubes across the inside of the fuselage that will take the dowls, this will stop the fuselage compressing and will give a good location point for the wing.

Yep Tonys suggestion is a good one, but you will need to put some ply doubler's round the tubes to stop them slowly getting out of alignment with flying stress and fitting/dismantling over time - doesn't have to be thick though

Hi All, does anyone have any clever ideas of fixing the wings rather than the "Cup Hooks" and elastics as suggested in the plan

Nylon bolts from inside the cabin into captive nuts on the wing root rib - if combined with wing tubes (that would take all the torsional strains - the bolts could be quite small as they only have to keep the wing root against the Fus

Some lite ply across the inside of the wing root rib bonded at each end to the wing tubes would be fone for holding the captive nuts too

thank you Dave, that seems a much better idea than elastics and cup hooks, will see what i can do.
