Glen Ogle

[gtmspyder]

I've done a little more work on the viaduct today, getting it ready to start scribing the stone work.

The hardened DAS clay was sanded flat ready to start the scribing process.



I then set a double pointed compass to a scale eighteen inches and struck off the dimensions around the arch support stones.



I then made more prominent the lightly scribed lines using the Exacto saw.







Then the horizontal lines of the structural stone work were scribed.




The dust from the scribe lines was continually vacuumed away, but I still ended up looking like a red Indian ;D



The part finished length of viaduct just waiting for the random scribing of the vertical lines of mortar to be applied.






Still plenty to do on the viaduct but I'm hampered by my leg some what.

it may be hot but I am watching the transformation !

I agree - looks good.

I must admit to feeling a bit queasy when this page first loaded - the top photo looked like you'd done something to your fingers - especially with the watch just visible!

[gtmspyder]

No Hugh, still four and a thumb on each hand. ;D

I've just finished scribing all the stones on the Viaduct face, and there's a lot I'll tell you.

Debating whether you lot will notice if I do not scribe the stones under each arch, something tells me you will. ;D

Duck's flippers?   ;D

Just kidding - the work being done on Glen Ogle is excellent. I'm looking forward to seeing further scenic development.

By the way, in the latest RM is a photo of a Caley 0-4-4T on a standard gauge train in Glen Ogle, in case you're interested.

Hello Ted.
Thank you for your interest.

I have the copy of RM with the article about Caley tanks, very fortuitous considering there has been very little information about the Calendar and Oban railway.  I only buy an occasional RM if anything catches my eye, as I subscribe to the Model Railways magazine.

That was a daily run from Killin down to Calendar and back for the school children, I think the engine was stabled overnight in Killin. 

I'm not certain whether it returned to Killin during the day to be able to transfer any residents from Killin to the interchange station to allow passengers to catch the trains to and from Calendar and oban during the intervening hours.

The engine would have had to reverse around it's carriage at the interchange station at the head of Glen Ogle to stay in front of the train going down the Glen to Calendar.

Are you going to be counting the under arch stone work Ted ???? ::)

Regards,

BrianT.

Counting the under arch stonework? That would be like picking nits, would it?  :o

I like the Caley tanks by the way - a nice example of the large wheeled 0-4-4T. You'd think the large leading wheels would climb the outer rail on a curve, but the weight aft would shift to the outside and help guide the front end into the curve. I found this principle mentioned when reading of the LBSCR 'Gladstone' class in a book on Stroudley.

Off topic of course...

[gtmspyder]

It would indeed Ted, but you can bet someone, some where, will. ::)

Brian,

I think it will depend upon what the viewing angle is going to be. If the arches are below eye level then I can't see that you need to go to the trouble but if the viewers are looking up at the viaduct from across the glen as it were, so that the arches or part of the arches are visible, then it may well be necessary to show the detail.

Perhaps a compromise would be to show the first couple of rows of brickwork that may be visible - by trying out all possible viewing angles, then "fading out" towards the back by painting the underside of the arches in a darker colour?

Just an idea

Good morning Mick.

That sounds like a plan :-* I may well have a go at that.

More scribing on the viaduct.



The dental picks used to create the effect.



It is a very tedious process but the finished effect makes it very worthwhile.  
The more observant amongst you might notice that the capping stone are not the DAS blocks I so carefully made.  I have instead cut strips of plasticard of the correct width, and scribed the capstone lengths along them.  I ran out of patience trying to fit the separate capping stones as I kept knocking the first one placed off as I tried to position the second. ::)



You do need good light, and a steady hand.



The bright sunshine helped with the first requirement, I'll have to take more pills to help with the second. ;)



More later when I have given it a coat of mortar paint to fill the scribe lines, and painted the capping stones to try and match the walls.

Regards,

BrianT.

More photo's as promised earlier today.

With a little varnish added to the water courses, the viaduct with a coat of very dilute black to fill the mortar courses, a scattering of straight from the bag Chinese trees quickly planted, two lengths of Peco narrow gauge mainline rail placed on the viaduct, and a Lilliput 060 and goods van placed upon that and voila.





You might notice a little in front of the engine a new addition to the scene in the form of a yet to be finished water fall feeding the brook that passes below the viaduct.



This is to help disguise the cross baseboard joint and is a piece of plastic sheeting I had lying around, Not Plasticard.
I cut a one inch groove in the baseboard over the joint, biased to the right as you look, of the baseboard joint.  The piece of plastic is glued to the right hand side of the back overlapping the left hand side of the joint such that in theory,  (I haven't tried it yet) ;) when the boards are split, the fixed plastic will move away from the joint.  This will make the protruding piece of plastic vulnerable to damage as the boards are handled, but we will have to see.



To try and hide the base board joint where the road crosses, I have modelled a half dug trench to disrupt the traffic, as it climbs Glen Ogle, this is just visible on this next photo.



One last photo for tonight looking back down the Glen.

that is some transformation and it can only get better

Thank you Peter, I would like to think so  :)

Getting ready to lay the bit of track that traverses the Glen, all 8 foot of it.

The main bit is the part that crosses the viaduct, need to make sure the viaduct always fits in exactly the same position, and because it has to be removed to disassemble the layout, it needs an easily disconnectable feed.

To achieve this end, I have come up with the following method;-

   I have taken eight lengths of pcb the width of the track bed, and in four of them, drilled two holes to accept 6BA bolts as two pairs to be bolted together.  the 6BA bolts were sweated in place into two of them, two colour coded lengths of feed wire soldered in place, and an insulating break was cut across the pcb.






The length of pcb with the wires attached, was fitted below the fixed end of of the track bed at each end of the viaduct, with the bolt lengths protruding through the fixed track bed tongues that support the viaduct, and onto these protruding bolts, will drop the viaduct proper.



On the viaduct, the twin piece of pcb with the holes, will drop over the bolts already protruding through the track bed, and be glued into place.  With the nuts fitted to the top, the power is carried from below to above the track bed, the viaduct rails will be soldered to the top of the pcb at each end.



I have also done a little more scenic work, I did not like my first effort at a landslip, so this is my second.

It now starts above the track bed, has spilled across the lines and on down into the bottom of the glen, blocking for a time, the river bed, and across to the opposite bank.  The river has cleared itself by washing the debris down it's length

.


Another coat of varnish has been applied and run over the land slip debris.



Here is a comparison between the two land slips.



And one or two small areas of water have collected in several depressions around the area.



That's about it for tonight,

BrianT.
