Re: Time to build a railway...but where?
I have now set about the repairs mentioned above and have made a surprising discovery. The building which had a loose ridge tile strip was in worse condition than previously thought. When I removed the ridge, made from HIP and plastic tube, it was intact but separated from the resin roof panels as the adhesive hadn't held.
Also, the resin sides had become detached in places from the resin roof sections.
I know manufacturers go to great lengths to ensure their products are able to withstand exterior use in all weather conditions, and to a degree they do, but...... This is one side of a resin building which has distorted.
Whilst my HIP structures have 'welded' components together, resin ones rely on adhesive, which is obviously the weak link. I used two part epoxy adhesive to bond them but it has not been up to the job. Is there a better way?

Re: Time to build a railway...but where?
I only have limited eperience with resin kits outdoors - 2 to be precise; a GRS windmill and a GRS station building, both of which have been outside since 2014. Although the paintwork is a pain, alway peeling off, I'm not aware of any adhesive problems. However, I'm pretty sure that I used Isopon car filler to stick them together and also to form reinforcing fillets on the inside of the joints.
Looking at your picture there appears to be a fair degree of warping. Since resin slabs can be straightened/flattened before assembly by gently warming, I wonder whether you might have done that originally and the curve has slowly reverted over time?...or whether perhaps it gets the sun on that face and the heat expansion and contraction has weakened the bond and allowed an expansion bend to form?
Just thoughts.

Re: Time to build a railway...but where?
Just catching up on your thread Peter - love the drone video!
Your building storing exercise reminded me that I need to do that too. That's mostly station buildings in my case, which encouraged me to run a last passenger service yesterday, pictures later.
I'm glad your buildings have stood up to the weather well, that's very impressive, especially as you've got so many of them. Mine are doing OK except the one tat I can't take indoors, the tunnel mouth. The embossed stonework started peeling of that again, until I attacked it with a staple gun in desperation! I'm hoping the staples will tone down to near-invisibility in time, but I need to touch up the paintwork anyway.
Cheers,
Andrew.

Re: Time to build a railway...but where?
I am just dipping my toe in resin buildings for outside, and from what i have read Isopon P38 car body filler is recommended by quite a few people, just letting some dry on my new build as I type, and from what i have seen so far seems quite strong.

Re: Time to build a railway...but where?
Thanks guys, interesting subject and one not covered elsewhere on the Forum, as far as I know? Resin structures are growing in availability and popularity but are not yet fully tested on-site in varying conditions and over time. The resin itself has issues with paint peeling and distortion, possibly causing joint stresses and separation? I remembered to score contact surfaces before applying adhesive, but that isn't sufficient it seems.
I have structures made from concrete, HIP and resin. My personal conclusion would have to be not to use resin structures in the future as their maintenance level is higher.

Re: Time to build a railway...but where?
Andrew, if your embossed stonework sheet is attached directly to a timber support my guess is that moisture and expansion is responsible for separation. If a plain sheet of HIP is stapled/nailed first to the timber and the embossed sheet then fixed with solvent, it might stand a better chance of staying put, as well as hiding the nails ?

Re: Time to build a railway...but where?
Hi Peter,
Thanks for the thoughts, but the tunnel mouth is exterior grade foam board, with the embossed sheet held on (or not!) with FloPlast solvent - I think the problem might be that there's very little contact between the embossed stone and the support. Oh well, it's holding togeter for now, I'll just need to factor in a little maintenance... My problem is that I much prefer building new things to repairing old ones!

Re: Time to build a railway...but where?
I am a little surprised with some of the negative comments about resin buildings, I have around a dozen resin structures on my railway from three different suppliers ranging in size. My preferred method of assembly is with construction adhesive in a frame gun as you can build up quite large fillets if need be to accommodate poor alignment issues, on the first few structures I reinforced the corners with aluminium angle but later dropped that idea as I found it to be unnecessary and now only reinforce the rooves as I find that sometimes they are prone to distortion dependingon their size and shape. Cleanliness is certainly an issue and a good scrub with detergent in warm water before assembly starts l find will suffice. As to painting, I prime all over with grey primer in a rattle can from Halfords as this is a good all round base colour to then add weathering effects with different colours applied with a sponge and these paints are always anything that is to hand from any supplier. The only problem that I've experienced is with using shades of red in acrylics on doors and windows as these fade very quickly in the sun and here I have repainted with enamel types.
I do however store my buildings under cover during the winter months, usually early November to about mid March and I will admit to a small area of paint chipping on the roof of the engine shed where blackbirds seem to enjoy perching and their claws have left their marks.

Re: Time to build a railway...but where?
Somewhere I have mentioned the PDF Double Fairlie kit I am building, along with another garden railway modeller, for a mutual friend who bought it, opened the box, closed the box, and called for assistance. Alan is putting the bogies together and adding Deltang RC, meanwhile, I am doing the bodywork. Eventually the two will be joined together, but for now I can only show my part of the kit.
As with all PDF kits, the printing is crisp and every part is a perfect fit to its neighbour. I like to improve the surface by smoothing out any printed lines..... After a coat of filler primer followed by grey primer, the parts become ready for top coat..... This is as far as I have got to date, plenty more to follow.

Re: Time to build a railway...but where?
Would you be able to help me out here Peter. What filler primer do you use and why have you primed some parts different colours. Is it to help identify them when you come to paint them and do you paint them before or after.
Sorry if it sounds like stupid questions and going in advance of your build, but sometimes I need my memory kicking back into life.....

Re: Time to build a railway...but where?
Rod, not silly questions at all.... the filler/primer is from Halfords and builds up small depressions in the printing. The grey is ordinary primer. So, dependent on print quality and whether or not the section will be easily seen I have the two choices. No difference in price so they could all be the same.
I usually give a grey primer on top of the filler/primer to accept the top coat of paint.
I will paint top coats on separate sections and hand them to Alan for final assembly, this way he can install the electrics without having to take things apart.
This is just my way of working, I'm sure there are many alternatives.

I was hoping we were going to see a Double Fairlie in LBSCR style "Improved Engine Green"...

Re: Time to build a railway...but where?
If 'Improved Engine Green' has a hint of maroon, then you're in luck!

Thanks Peter. It's very helpful. I have just received the his new Skylark last week. Not opened any of the packaging yet.

Re: Time to build a railway...but where?
I'm very tempted by the 'Skylark' too, a nice looking locomotive. I hope you can post your build on the forum, it would be interesting to see how you get on and what we should be aware of. I'm interested to know how many AA batteries you can fit inside?

Re: Time to build a railway...but where?
Changing the subject yet again, I received my latest kit today from Jerry Irwin, the Corris Brakevan. I love his kits as they are a pleasure to make following the Youtube videos and always result in first class models with superb running in ball bearing bushes. This kit has various options contained in one box: with or without duckets, early or late structural bracing and end panels etc. I haven't yet decided which to do but I have the ability to do a dry-run before I commit myself..... incredible value for money I think......

Re: Time to build a railway...but where?
You lot are making my mouth water with your Skylarks and Corris brake vans, both of which I'm fond of... That does look like a splendid kit, looking forward to seeing how it turns out...

Do you have a link or web address where I can have a look at the kits ?
