Ok, it’s about time I did a bit more tinkering...
This is a picture of the current state of things. It looks like we need to get threading some chairs.
Slowly tapping away at the master board leg job.
- I’ve re-enforced the board ends.
- put some tabs on the top of the legs and drilled holes to align wth the existing.
Here’s one half of the ‘L’ bolted in place.
(I know the subjects a bit dry but it motivates me a bit posting this stuff, so bear with me..)
I’ve started stripping down the ‘A frame trestles this morning.
Measurements have revealed that the component parts can be reused, this is a big help potentially saving a lot of time.
Here is the ‘L’ shape arrangement I’ll be using for the master board.
You've obviously not felt the draw-bar weight of my china clay rake, I think most of the wagons have 'dragging brakes'.
Surprised the wheels don't have flats on them...
I'm not sure which way to go on this. Ultimately loosing 15-20mm on the straight section at the back, which is at least 20 feet long, shouldn't bother anything, however loosing the height either end around the curves feels neater.
Hmm.
Yes agreed, this is one of the reasons I'm taking the measurements - to work out what the difference in the track height is end to end. I can then look at how I counter that in the new back fiddleyard.
For those that don't know, the main lines on BCB are built on a 1 in 100 gradient from the viaduct down to the tunnel. Now the layout is becoming a complete circuit this obviously needs to be addressed in the new fiddleyard somehow.
For my reference, this is the measurement from the bottom of the board to the floor, ie the length the new leg needs to be minus the depth of the adjustable feet.
Its around what we’ve standardised on over many years, perhaps a couple inches higher as I think 46 to rail height is our norm. Quite where the extra 2 crept in from I’m not sure.
The legs will just be straight forward hinge down with a brace, hopefully I’ll have a go at the weekend.
One of the first things I’m going to sort out is the leg arrangement. For BCB I used the same arrangement as I did for ‘Diesels in the Duchy’ namely tressels and timbers forming a subframe.
Trouble is you end up with lots off loose bits. To sort this I’m going to hinge legs on each board and piggy back off the master.
