There's actually a Marillion album called Anorak-no-phobia.

Actually 2 of the albums I listened to whilst tiling where FEAR and Brave! Apt indeed.

I thought a Marillion fan clutched at straws, not anoraks...

Paul

All (alright both or 3 if you count the drummer change) incarnations of Marillion treated equally here! Straws, Anoraks, fishes, "aitch"es whatever...…. Although given the state of the country at present perhaps I should concentrate on Fugazi.

I'm gutted I can't get to Cambridge for SRB. Last year I couldn't get to Holland for it and this year I will be in Holland so can't go! Definitely recommended though, seen them a few times - they're really good and Martin (from Edinburgh based tribute act StillMarillion) who sings the old Marillion stuff is excellent. The set list is around on facebook if you search Steve Rothery. Definitely the whole of Misplaced Childhood and Clutching at Straws from what I can remember.

I'll just have to be happy with the Mariilion Weekend convention in Leicester in April.

Cheers

I thought we had reached seasons end with all this misplaced nonsense about Los Marillos...
However, I FEAR some will always be clutching at straws with regards to the past and not be brave enough to move on.
My marbles are well known for being wonky but this band continue to thrill with their sounds which can't be made... :thumb

Agreed. They get better with age and are still original in almost everything they do. It's been a great ride for more years than I care to think about. Looking forward to another new album sometime next year, and the gigs with orchestral friends in the autumn, plus of course the weekend in April.

They really get this Strange Engine into gear. You can feel the Radiation -perhaps it's time for some Holidays in Eden, but only if you're not Afraid of Sunlight, in which case you could go Somewhere Else! Although I know that Happiness is the Road, I'm not sure how to get the (sorely underrated in my view) .com into the discussion, but the real prize is for some one to work Script for a Jester's Tear into it!

Once that is achieved I suppose we should go back to talking about Railways?

Just to draw a conclusion to the Marilli-ness in this thread, here's all five (post 1989) members of the band in loco form on Cadhay. These are all Hornby Railroad industrials. It appears there's a prog rock fan in Hornby's graphics department and he's been sneaking in prog related locos for years! These cost me around £15 each. Some have had straight wheel swaps (not worked that well) and the eventual aim when I get time is to scratch build a simple chassis for each. watch this space....

Meantime I have made a bit of scenic detailing progress in preparation for Holland this week. The washing line now has clothes hanging on it!!

Also my mate Chris McCarthy has P4'd the EM LSWR G6 picked up at the Southampton show last year and that had it's first timetable run at yesterday's final practice session before we break down for Houten:

Had a great trip to Houten, near Utrecht for the Rail exhibition with Cadhay last weekend. Here's the only two snaps I took as I was a bit busy over the three days.....

19-02-008.jpg
The A3 notices on the front are the complete days timetable in English and Dutch and you can also see the layout clock that we now have to keep time to!! Takes about 2.5 real world hours to run through the day.


19-02-009.jpg
Thanks to this set of fine operators, our "on time" % was probably pretty prototypical too.


Layout performed well, with the only mishaps being the 2 point blade actuators I've not switched to the new style through board connection, so they are next on the list of jobs to do.

The signalling and bells created lots of comment and also our uniforms were commented on a fair bit also. Plenty of questions about the AJs and how they worked in the sidings as well.

All in all a thoroughly satisfactory show.

Next up for development is a scrolling LED matrix under the clock to do away with the timetable prints!

Cheers

Spent a relaxing day today recovering from a hard day having Cadhay at the Skills day in Linlithgow yesterday. We ran without the curtains up and had lots of conversations of the "how do you?" or "how did you?" variety. I found it a most interesting experience and it was a pleasure to chat to knowledgeable folks all through the day. Even had a chat with a fellow prog fan. And kudos to Dave Gower who made it all the way from the South to inspect the layout for any sign of the copper dome!!!!

Cheers

Thanks Chris. I really enjoyed seeing your layout on Saturday and had a great time at the event. Well worth the trip up. When you were not looking I planted an IED under the track which is set to take out any GWR intruder. LOL.

All Best

Well flipping heck, over 6 months since I posted anything on this! That said not a lot has happened in Cadhay world since March other than the implementation of the speeded up clock and LED Scrolling Matrix displaying the next train details and a successful outing at Cupar MRC Exhibition in July (voted 2nd best layout). To give you a flavour, here's a photo of a right bunch of likely suspects looking smug cos they've just cleaned the track or something...

CuparShow1.jpg

Mainly though this hiatus has been due to work on Burntisland and it's presentation rig this summer taking up most of my spare time (and then some!).

Anyway, now I'm back in Cadhay improvement mindset, work has started on a replacement fiddle yard for the Cadhay ST Mary end. For those that have seen the layout this is the left hand end where the fiddle yard is operated open to the viewers at an exhibition with the off road from the layout coming in from the right. Currently it operates with the original cassettes I built as a temporary solution. It's being replaced with (I hope) an electronically controlled 6 road traverser plus loco storage and run-round facility that should make operating this end a lot easier. Here's a templot output plan for the traverser which will show the idea:

csm_traverser.jpg


As ever with Cadhay this is an experiment so it may not work (first time) but my intention is to post progress along the way.

The traverser will be moved by a stepper motor driving a pair of lead screws via a timing belt whilst running on a pair of linear guide rails as per CNC/3d printer. It will be controlled by a pair of Arduinos, one for control and with a DC power shield to run the locos in "local" (rather than "layout") control mode, and the other to control the stepper motor via an 8825 driver.

The electronics are currently mocked up on a breadboard on my desk looking like this:

Control Electronics.jpg
Honest it does work!


and the basic frame is now taking shape as per this photo:

Trav Body.jpg
The sewing machine is not part of it!


The traverser tray is also built and in the workshop so over the next couple of days the plan is to fit up the belt and try to get the stepper motor to shift the tray! Wish me luck.

Correct length timing belt arrived earlier in the week which allowed me to get the traverser motion fitted up and trialled. So far it's looking very accurate in repeat positioning. Spent some time yesterday evening sorting out the Arduino programming for an emergency stop (I envisage the operator may need to stop a move if a coupling snags or something else gets in the way).

Here's a view of the frame showing the transmission by belt from stepper to gears on each end of the lead screws with a pair of belt tensioners (they also allow the belt to be slackened for removal and replacement). The movement of the lead screws is transferred onto the angle that in this shot is at the front. This will in turn be fixed to the track tray that runs on the linear bearing tracks shown in the next image.

Trav Transmission.jpg

Next is an overall of the traverser frame with jury rigged electrics transferred from the desk. Movement angle now further back.

Trav Overall.jpg

This allowed some operational testing and it seems the movement is really quite accurate so far.

Finally I've finalised the control panel design.

Just need to laminate and mount onto the plate and I can start fitting the buttons/LEDs etc

OK so in spite of a load of work on at the moment, I've made a bit of progress on the traverser. In fact today it had it's first full testing of a run round and an engine swap.

There's some video of the engine swap at the youtube link following. Excuse the dodgy camera work - I was operating and filming at the same time, but you get the idea....

https://youtu.be/uXBuQdJ3kC8

More to follow perhaps, once I find a competent cameraman!

That is seriously impressive, the ingenuity is fantastic. You could practically sell them! any one to purchase 2 and then all you have to do is build the layout in between or change around to have different layouts with such a great fiddle yard system!
