Re: Brimsdown-The last grand project.

Next came the tricky part. I decided to cut the straight side first. Several 70mm wide strips of 18mm plywood were cut from a sheet. The Mitre block was then set to 15 degrees and the table set to 25 degrees. The way each angle goes needs to be thought through to make sure the angles end up the righ...

Re: Brimsdown-The last grand project.

Why do I call the lifting flap the ultimate challenge? Well there are so many elements to it. The board forms part of a curve for a start. The inside edge is straight, but he outside edge is a compound curve being part straight part curved. In order for the hinge axis to prevent the rail ends clashi...

Re: High Level 03 Chassis Build

Plunger pickups are a dead loss, effectively acting as a heavy brake on the wheels. Wire of any sort is much better. Philip My experience with plunger pickups mirrors Philips.

Hi Tony. One of the things I love about these threads is the gems that come to light along the way. I would be very surprised if the transport was not by rail. Almost any factory worthy of the name seemed to have a rail connection back then or access to a nearby railhead. Talking of smells. The rail...

Re: Brimsdown-The last grand project.

Hi Philip. You may well be correct as I have never really been sure what insulation board is. All I know is that fibre board is a general term and Sundeala is one brand. It is sold for use as pin up notice boards as well as baseboard surface material. Certainly Conti board is consistently flat and s...

Re: Brimsdown-The last grand project.

Hello Tony, Would I be right in saying that Sundeala board is what used to be known (in the 70s) as soft board or fibre board? It looks like it. Back in the day, I had some base boards made with that material and even with coarse scale 00 gauge track there were problems - never again! Hi Colin. Yes...

Re: Brimsdown-The last grand project.

Now for the fourth and final straight scenic baseboard. Although this was the first scenic board I looked at, (primarily because it would ultimately have the lifting flap attached) I ended up starting them from the other end, for two reasons. Firstly, this was the more complex end and thus key to ev...

Re: Brimsdown-The last grand project.

I do not find the recent spell of hot weather conducive to doing much outside. Due to the thick insulation of my garage, it is often the coolest place at the moment. I did consider air conditioning for a while, but difficult to justify for a garage. However, by opening the windows overnight and clos...

Re: Track versus weather

Hi Paul.
As tarnishing is basically oxidation, which is a chemical reaction and chemical reactions generally accelerate with increasing temperature, I suppose this is to be expected to some extent.

The Brimsdown chronicles.

The next stage was to dismantle both the curved baseboards by removing the screws and gluing all permanently into place. Once set a multitude of diagonals were cut and planed to fit before fixing in place. This four section baseboard is upside down and had a slight twist, hence the clamp and weight ...

Re: Brimsdown-The last grand project.

Meanwhile, visible in the background of some of the above shots, progress has also continued with the baseboards for the north end curves. I have been cutting strips of 4" (100mm) wide 9mm ply to length and cutting the angled corner blocks while waiting for glue to set with the scenic boards. S...

Given all the information on expansion that has come light here, I shall iam to allow a 0.5 mm gap per 500 mm (nickel-silver) rail length, or 0.25 mm per scale track...

They depend on having square edges and checking the face is flat as the clamps are tightened, they do have a tendency to go out of true depending on the grip of the clamp jaws This can also happen if traditional screw operated sash cramps or G clamps are used and is a problem with this sort of appl...

Re: Brimsdown-The last grand project.

Thought I would cover baseboard 3 in a bit more detail. The first step is to glue the four cross ribs in place. The 1" strips fitted to build up the end boards need to be vertical and flush with the end face. They depend on having square edges and checking the face is flat as the clamps are tig...

Re: Brimsdown-The last grand project.

A brief update. Number two scenic baseboard is now done. Not many detail pictures, but steady progress being maintained.

Here are the first two in place. The low sun coming through the windows really doesn't help the lighting for the camera.

Re: Construction of a Test Track

In this case, I had broken my own rule about never having a single length of rail longer than about 420mm, and needless to say, rework was needed. Even if the rail is in short enough lengths, it is easy to allow insufficient expansion gap. I know Tony Wilkins follows a policy of never more than a s...

Hi Terry, Colin. Terry is absolutely correct about how I modified the vice. I did this many years ago when I had a series of F-16 turnouts to construct for Ken York's Addison Road project, which unfortunately never saw the light of day. I purchased a foot length of 1/2" square mild steel bar an...
