One station of the Devan & Summersett

I think your Chux cloths are called J clothes here in the Uk Ron

Your are right its best to have multiple jobs so you dont get to pissed with one of them.


You mentioning plaster Ron prompted a question for in Australia as its is usually bloody hot what time of the day do your builders work as with your temperatures they must get problems with cement going off super fast or do they use some sort of de cellerator?

I think its called  "fosters" Brian.  Slows me down anyway.:mrgreen:

So far as I'm aware builders (and other "outdoor" tradies) are not required to work when the temperature goes above 36C.

It's an occupational health and safety thing as much as anything.  Cement and plaster does go off extremely quickly (and cracks :twisted:) but that can be fixed.  The effects of dehydration and sun are not always as easily fixed when you're outside day after day.  Either can prove fatal.

Brian,  cement must have been changed coz years ago, house foundations sat for months to cure but nowdays with the raft, about 3 days & they start building. I will admit, I have not seen them pour it on hot days.

Now plastering on our empires, well there are methods to slow down the setting such as adding PVA, vinegar ( not sure about the salad smell though).
One of my modelling mates uses  paper towel in small pieces over a criss-cross of corrugated cardboard, glued with watery PVA brushed on & into the paper. About 3 layers & that is it - for rolling hills etc.

I think it's 38 degrees, Rick - the old 100 in Farrenhoover.  Used to be we got sent home from school if it got to 100, but we didn't have airconditioning (or refrigerators!!) in those days.

I think i would give up at nearer 30 degrees mind you im not used to high temperatures like you are.

The cracking must be the problem as thats what occurs when it dries to quick i asume they must use an additive to prevent this.

Sorry for diversing your thread Ron

Brian

I started on covering the foam as it is part of the road climbing to over the bridge.




some was plastered & others tried with PVA - the bits sticking up PVAd at the base & will be bent over - PVA smeared all over.


The big piece of Chux, glued to baseboard  with PVA & will be anchored to foam into shapes with Liquid Nails which was also used.



The piece of Chux at the top of the photo was across a gap., glued with Liquid Nails which was good enough after about minute then to allow me to brush into the rest of the Chux with full strength PVA, that piece is now firm enough for me to add some more. To make it a bit harder, this is across the liftup so there has to be a fine gap.

A bit of a ( well no, a big) mess but I take heart in that others on YMR start off with a mess & end up with a miracle so I may also get better !

I thought I would try all methods - each has its own atrtributes I trhink

All of the above was done 14-15 hours ago & the plaster is dry.

It's a good idea to try all the methods, Sol.  :thumbs

If it works ………… ;-)

It certainly has the look of a good business-like structure about it Sol so carry on and all should come good.

Layouts seldom look their best when they are at this stage but as we all know if this bit isn't right the finished product won't be either.

Thanks for showing all the steps in creating the landscape, Sol.  Another thing I have never done, so these "how to" giudes are absolutely invaluable.  It's great to have that depth of knowledge on the forum and wonderful that it is shared with all. :thumbs 

At the rate I'm building it may be many months before I get to the mucky stuff, but at least I'll know where to go for reference articles come that day.

Looking at those shots Ron, it seems you are using the Chux cloths as a "carrier" for the plaster rather than soaking it in plaster first.

I wonder how much effect the PVA has on both drying times and flexibility……………:roll:  I also like the "No More Nails" type glues, they may be more expensive than PVA but are both strong and fairly quick drying - patience never was one of my strong points !!!!

PVA is slower but again gives a base for plaster. "No More Nails/Liquid Nails is very quick indeed, I found a tube I was given some months ago

If I didn't have the foam as a freebie. I would have used flywire & straight plaster.

What I glued this morning has not all set so I can carry on with more tomorrow ( nearly 6PM here now - Dr Who is on the Box soon - I have been away since 11AM on visiting me Ma in a Aged Care Home)

Looks like a fine start to me Ron, looking forward to the next installment........ the scenics :thumbs

 

This is the gradient of the road on the lift up with all plaster. I have not yet decided on the road surface, either DAS/Plaster like MikeC has done or use the Scalescenes tarmac which will match the bridge road surface.






Now to carry on with the area near the bridge - at least get the Chux covered.

I have been doing more plastering in between cards & track & points & wagons & this time instead of water, I used common old white vinegar - certainly slows the setting time down . Have to see what the smell is like tomorrow.

Eet might smell like sauerkraut!

I am very impressed with Dr Who's latest assistant!  I think their adult male viewing figures have probably rocketed this series!

Are you planning on working your way through the complete set of condiments in your plaster mix Ron?

Are you planning on working your way through the complete set of condiments in your plaster mix Ron? As vinegar is brewed from fermented spirits, I could try other fermented liquids . :cheers

The lastest batch is still damp after 14 hours but being cold weather  overnight may have something to do with it

Are you talking about the effects of Dr Who's latest assistant Sol or the salt and vinegar candy mountain ? :roll::roll:

Yes !!
