Instead of a date, try a masonic symbol as a conversation point, they are quite common if you know where to look

Lumsdonia has lots of of civic pride, so it will get a date.
Masonic symbols? Have you seen how complex they are?
Roman numbers, nine digits instead of four!
It will get 1893 in the format "1893"! :)
I doubt I can carve them, so I have a cunning plan! :P

The cunning plan was ill fated, I only have letter stamps! :shock: So it will be on to plan B, hand carve! :o
Things are progressing elsewere! The stayed cable bridge has been fully cabled, the deck is made and prepared for all the cables. Stone bridge has one side completely covered. All 5 steel bridges are made and painted.
I need some fencing for the bridges. I have bought enough for the cable stayed from a laser cutting company, torri_laser, but I don't want the same for the steel chord bridges and cant find anything suitable that is reasonably priced for the length, so yesterday I made a jig and started making my own from 0.8mm brass wire! :eek: (it takes forever!)
I bought two canal boats from Craftline and am replacing the supplied prints for the sides with my own.I have cobbled together enough photo's to patch them together to use on both boats, but now need to trial and error print and fit to get the right scale!
Checked the clearance and the canal and a tow path will fit under the bridge (I left the end too long to enable integration into the cliff), I was a bit concerned, as the Crafline are broad beam, not narrow boats!
So here are some views of the texture roller bricks. The corner stones are laid on after and grooved. This is the back (unseen side) that serves as the first go, I have yet to tackle the other side. I am not sure I like the corner sides sticking out proud (it was a quick fix to lay DAS on, after the sides had been applied).
I have yet to decide if I can stomach routing out a rebate into the brick after laying the brick, although I could do it by cutting when soft when I lay the bricks on the other side.
Yes I know the bricks ain't very even, but this was a test. Obviously rolling the pattern is good on a flat surface, but moving it to the bridge, inevitably allows stretch and misshaping before it lands! I am not sure that rolling on the bridge won't produce an undulating surface!

Hi Timber
How about this MDCCCXCIII, 1893 in Roman numerals.

I will have a go at hand carving, if the results are rubbish, then plan B will be to use my letter stamps and do it in Roman numerals :)

Some highly inventive plaster workings.
Lovethe results.

Should be much better once I do the other side (I will be more experienced/accept only higher quality) :D

So on to the cable stay bridge. The deck consists of 6mm ply, with a 20mm x 10mm aluminium tube under the centre and 15mm x 10mm aluminium angle at each side. The holes are drilled for the cables and preshrunk heatshrink inserted in each {they will act as a sleeve to allow the cable to move freely}, at the correct angle and glued in. Screws are adjacent to each hole underneath, with a spring attached which (hopefully) will keep each cable independently, taught. The gap between the aluminium will be covered by a plate to hide the cables and springs.

The tower has holes for the cables, with a brass sleeve before the hole to keep the knot away, allowing preshrunk heatshrink to protrude, but not slip down the cable. As this means nothing is glue at the top, easy maintenance or replacement can take place. The slot was needed to allow threading of the cable deep own the tube and will be covered by a plate later on.

Looking good Timbersurf!! On a personal not it is very depressing to see other members making great progress while I am ripping mine apart :cry:

Cheers BuffyMcBuffer

Take heart Jim, your layout has been very inspirational to me and bear in mind, even when this module is complete, it will just be a "photographic diorama", for many years, till I too move house and have enough room to make a layout I can actually run trains on!

Only just caught up on this resin casting of brickwork - quite remarkable. What sort of a learning curve is involved, and how did you get into it?

Resin? Noooooo.......

I played with Linka when in my teens. I see the joints as the problem, very hard to disguise. The stone type however are much easier.
I either use a silicon rubber cast from a master made of Linka tiles or cast a flat sheet from a plasticard sheet of stone, then cut and carve the master (simple chamfers at corners). The female mould can be made from builders "gun" sealant (as used on your bathroom), this is a slow process and can only be used on flat surfaces (upto 5mm deep) else has to have a former box as well. The other way is to use proprietary modelling 2 part RTV silicon (more expensive) but can produce more complex 3D moulds, is quicker, and also needs a former box.
I think my gun method is very unique, but there are plenty of video's using 2 part type.
I just tried the gun method about 2 years ago and it worked. Using Linka as the base, it allowed the mass production of the station retaining wall and has progressed from there!
I originally started with very dubiuos 30 year old Linkalite plaster, but now use Herculite 2, very inexpensive when bought in bulk (a few Kg)
First attempts at "Gun Silicon" sealant method
First Linka tile structures
First mass produced "Gun Silicon" sealant
Second mass produced "Gun Silicon" sealant
Standard Linka build
Curved wall
Hand and roller formed DAS clay

I wondered if you'd notice that one!

Thanks for the very comprehensive reply - it'll take some working through - but at least I have already had experience of LInka back in the 80's.

Just added a Static grass Applicator guide to my website and started of a new page for 2019 in the gallery section, to catch up with the bridge valley module!

Took a brake from bridge building. I will have two canal boats on the canal and wanted some kayaks on the river, but they are about £12 a pair! So I had a go myself and knocked these two out in about an hour!
