Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

I am really just trying to understand how the left hand brake is applied... As I understand things the main rod linking to the brake actuator pulls the vertical blade at the top to the right. I am assuming this blade pivots around the position I have arrowed as the pivot. This pulls the right hand ...

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

Can't find your pivot 1 on your drawing. However. The bar which has your pivot 2 marked has another pivot at the other end where it attaches to the wagon frame. When you include that in it all works.

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

If you mount them in the bearing carrier with the plane of the curvature at right angles to the plane of the carrier, and solder them in so they can’t turn, the wire will be effectively strait. Thanks Will, I have soldered the wire in as I find the carriers very flimsy and was worried about fatigue...

Re: Making a Start - The Peak District Midland / Monsal Dale pre 1903

... The first is to do with the Bill Bedford sprung W irons. The guitar wire threads through the base of the waisted bearing carrier and then is located on either side in a pilot hole in the etch. The wire is not equally straight ... some sections having a slight curvature. This means that when all...

As with turntables, discussed elsewhere on this forum, a round-ended plunger pushed into a v-shaped or conical notch is a good way to get repeatable positioning.

Re: Traverser locking

A small traverser can, with advantage, be constructed as a sector plate rather than a parallel moving table, although on a short one, the track curvature needed at the end of the outer roads can limits the practical number of roads. One power feed goes via the pivot and connects to all the tracks on...

Re: Ballasting ply sleepered track

Tim I think your point about the presence or absence of a resonating space under the track base has as least as much to do with noisy layouts as the method by which the track is glued down. Set PVA isn't of itself a particularly hard or rigid substance. When used to glue things together there is typ...

Re: GWR Steam Railmotor Chassis

The key element here is that the holes are vertical and the resulting jig is a good fit on the axle hole and the drill, the exact distance apart isn't a big issue. The wheels should end up all the same and you'll never detect any minor departure from 2.6mm. I quite like our sedentary friends idea an...

I am not sure your reasoning is correct here. I'm with Tim I think your seeing problems that don't exist, even with ordinary, not waterproof, PVA. Lots of people have constructed track this way and if your fear was realistic i'm sure we'd know by now. Some people find the PVA/granite mix a bit rigi...

Will, it's a simple L shape fitted to the footplate.

Same approach still applies shurely? The vertical element soldered solidly through a hole in the footplate and the base of the L applied cosmeticly.

If you let a pair of P4 wheels roll freely along track that has the correct 1 in 20 angle and then try it with wheels and track that don't (00 or P4) you will see the difference it makes. Will you?

Seems we have had a lot of comment recently about the problems we get into trying to model the prototypical 1:20 inward inclination of track which appears to be leading to gauge narrowing. In the end you do have to ask, why are we bothering. I know it has been said that without the rail inclination ...

Re: High Level 03 Chassis Build

Hint. On a compensated chassis, it will bob most noticeably, if an eccentric wheel is on the fixed axle. An eccentric wheel on the compensated axle(s) will be significantly less obvious. Of course a CSB sprung chassis will be affected even less.
