RMweb Premium Physicsman Posted August 22, 2015 Author RMweb Premium Share Posted August 22, 2015 I've tried to be positive by changing the subtitle to this thread to "Stage 2"..... ha! Let's see what Monday brings! In the meantime, I continue to stare at - and refine - the baseboard frame plans: it'll be good to get the wood cut and screwed together to stop me coming up with any further ideas! Stay tuned - something MIGHT happen next week.... Jeff 3 Link to comment Share on other sites More sharing options...

In the meantime, I continue to stare at - and refine - the baseboard frame plans: it'll be good to get the wood cut and screwed together to stop me coming up with any further ideas! Stay tuned - something MIGHT happen next week.... Jeff I think that one of the great joys of L-girder is that it does not need too much planning/refinement. So long as the main girders are in the right place, everything else can be adjusted as you go along. Will be testing this theory shortly as I have been asked to rebuild a layout/train set for friends. First action will be to rip up the "flat earth" baseboard and replace with some L-girders and open-plan track bases. Fortunately they have just inherited a massive quantity of timber batten and screws from a deceased builder. Struggling with design though! After 40 years (on and off, mostly off) trying to build realistic model railways, they really want a big train set. 1 Link to comment Share on other sites More sharing options...
Jock67B Posted August 23, 2015 Share Posted August 23, 2015 Morning Jeff, Sorry to hear you've been let done by the timber supplier - you did very well to stay calm in the circumstances! Really looking forward to the build, now with heightened anticipation! Kind regards, Jock. 2 Link to comment Share on other sites More sharing options...
RMweb Premium Physicsman Posted August 24, 2015 Author RMweb Premium Share Posted August 24, 2015 Morning Jeff, Sorry to hear you've been let done by the timber supplier - you did very well to stay calm in the circumstances! Really looking forward to the build, now with heightened anticipation! Kind regards, Jock. Morning Jock. It's not quite Bolt v Gatlin or The Ashes, but I must admit that I'm really looking forward to starting something today. KL was dismantled at the end of November 2013 and it's been difficult to maintain the kind of enthusiasm I had way back then. Not because of any problem with model railways. Simply because other things have filled the void, including some older hobbies (astrophotography, for one), and it's been hard to motivate the interest in starting KL again. Please remember there are many, many ways - most more economical and (probably) better thought-out - to build this project. I'll just enjoy doing it my way and, hopefully, a few people may find it of interest. If not, well, there's hundreds of other threads to look at!

RMweb Premium Physicsman Posted August 24, 2015 Author RMweb Premium Share Posted August 24, 2015 Update: The "4 x 2" timber arrived at 3pm. The first 4 L-girder sections have been put together. I'll construct the base "table" and, maybe, put some pics on here tomorrow. Let me know if you want to see a bit-by-bit set of pics or just summaries and I'll try to oblige.

peach james Posted August 24, 2015 Share Posted August 24, 2015 no. no blood guts or gore. But lots of sawdust. If we have blood guts or gore, then Jeff will have been off to A&E, and there will be a delay in the next set of photos... I'm one for as much writing as you feel up to Jeff, this is YOUR thread, not us punters. James 1 Link to comment Share on other sites More sharing options...
Mythocentric Posted August 24, 2015 Share Posted August 24, 2015 (edited) Yep! I'm with James on this one! We're here to see KL2 take shape in the way you want and in your own time Jeff, not to put you under any obligation or pressure to perform. We saw the results of that way of thinking with Andrew and the outcome. As and when it comes is fine by me and look forward with anticipation (and patience) to seeing Jeff with a new layout and a full set of appendages!

RMweb Gold Donw Posted August 25, 2015 RMweb Gold Share Posted August 25, 2015 Be careful Jeff. While in the IOW the builder had a call from a mate, a chippy who had sliced the fingers off his left hand with a circular saw! Don Link to comment Share on other sites More sharing options...

The only problem this morning has been a couple of splinters in my fingers - with a little bit of blood. I'm very wary round circular and jig saws!!

RMweb Premium Physicsman Posted August 25, 2015 Author RMweb Premium Share Posted August 25, 2015 Ok folks, you wanted things a la minutiae...... So, for those not in the know (and I've had a couple of PMs asking me about them - not everyone knows this stuff....), here's an L-girder, with suitably colourful garden background. The constituent parts are a piece of 95mm x 44mm ("metric 4 x 2") and a piece of 70mm x 21mm ("metric 3 x 1"). The lengths are glued together with PVA and screwed at around 30cm intervals. The resulting girder comes in at 116mm x 70mm (roughly 5 x 3). I know it's a bit over the top, but it's the way I like to do things and that's not going to change!! More later.

RMweb Premium Physicsman Posted August 25, 2015 Author RMweb Premium Share Posted August 25, 2015 Starting the assembly of the first L-girder table. I'll post a plan later so you can identify which table goes where. Here, I've got 2 L-girders - upside down - sat on the cross-struts (70mm x 44mm), ready for fixing down: It's vital to get everything square in all directions - levels and squares are all over the place in the bunker! I scrapped all the woodwork from KL - it filled a large skip - because it wasn't easy to dismantle the structure when I moved. With the L-girders, all connecting screws (NO glue used) are driven UP into the horizontal member of the L-girder from below. This makes it easy to remove them - they aren't buried under scenery.... Well, that's the theory! I'm fitting 95mm x 44mm legs to the L-firders. Here's the first going on: G or C-clamps are a boon and everything is kept square and level (well, I TRY to!!): More later....

RMweb Premium Physicsman Posted August 25, 2015 Author RMweb Premium Share Posted August 25, 2015 Now for the rest of this "table".... More legs attached and some bracing added: The structure is turned right-way-up.... Now to start the next one - which fits to the right of this (as seen in the third of the 5 pics in this post) table. The next table is twice the size, so you MAY hear from me later!

RMweb Gold The Stationmaster Posted August 25, 2015 RMweb Gold Share Posted August 25, 2015 Jeff, With the significantly different dimensions of the two pieces in the L how does it work in respect of the basic idea of using the right angle between to stop them bending in either plane? 3 Link to comment Share on other sites More sharing options...

RMweb Premium Physicsman Posted August 25, 2015 Author RMweb Premium Share Posted August 25, 2015 Jeff, With the significantly different dimensions of the two pieces in the L how does it work in respect of the basic idea of using the right angle between to stop them bending in either plane? I'm not a mechanical engineer, Mike, but I don't think the difference in size has any bearing on the problem. The stiffness in the vertical and horizontal planes is conferred independently by the vertical and horizontal members. The 3 x 1 will act in the same way as it would if it was fixed on top of a vertical 2 x 1. The significant difference is that not only is the 4 x 2 stiff vertically, the additional thickness ADDS to that conferred by the 3 x 1, resulting in a VERY stiff girder in BOTH directions. I'd have been happy to use the 4 x 2 by itself, but the top "lip" of 3 x 1 provides a convenient place to attach cross-members. Jeff 2 Link to comment Share on other sites More sharing options...
RMweb Gold Donw Posted August 25, 2015 RMweb Gold Share Posted August 25, 2015 Nice workmanship Jeff. I do rather agree with mike about the L girder I think two bits of 4x1 would make more sense. I cannot see that bit of 3x1 having much chance of holding the 4x2 straight if it wants to bend. Mind you once the cross bearers go it and some are at an angle (usually to avoid a bearer under point blades) it will all be well braced.
