I simply point out that aeroplanes are riveted, bolted or glued but not welded. There was an aeroplane that was welded in part but managed to unstick itself on it's maiden flight - Hermes?

Have a look at HobbyCraft. They do some foam sheets of A4 and A3 of about 2mm thickness. I have tried them with some success. Secured with carpet spray glue.

That depends on the length of the Block Section.

4. set instrument to TRAIN ON LINE and then send 4 6. I get 2 dings from box A to tell me the train has passed box A and is on its way to me. Set instrument to TRAIN ON LINE 12 and 13 as in above post

Oh the irony of it!

8 times? Because it is the square root of the scale. So for S scale (1:64) it is 8 and for 76.2 it is 8.7. If you drop a ball from a cliff 98.1m high it will take 4.5sec to reach the ground. If you drop a ball from your S scale cliff (ie 1.55m high) it will take .55sec. 4.5/.55 ~8. So if you want to see your “scale” ball fall from your scale cliff in 4.5 sec then you shoot your film at 8 times the play back speed ie for 25 FPS play back you shoot at 200fps.

But the units of G (the gravitational constant) is m^3.kg^-1.sec^-2. So time is there like it or not.

And what is gravity? Length/time squared. So yes it is time that is the problem.

No it wouldn't - the dynamics would be all to cock. That's why you need to run at about 8 times (1:76.2 scale) of what you think is scale speed and then show the film at 8 times less speed. Think of the train falling from a bridge - do the sums and you will see the train hits the ground about 8 times faster than it should based on the naive definition of scale speed.

Before you start down the road of scale speed you first have to define what you mean by "Scale Speed". If you mean that a model traversing a scale mile in 2 minutes will be defined as travelling at a scale 30mph then that is one definition but it will not have any of the dynamic characteristics of a full size train travelling at 30mph. To have the dynamic aspects of a full size train at 30 mph you would need the model to travel at about 8 times the speed of the full size. The issue is that you can't scale time and time is part of velocity and acceleration.

You should not be attaching the Tortoise directly to the baseboard in any event. If you look at the base of the Tortoise you will see it is slightly bowed. By attaching it directly you are in danger of failing the attachment lugs. You should use some sort of stand-off so as not to stress the attachment lugs.

Reamers have a defined hole diameter from which they produce the reamed hole. So you are going to have to drill the hole first before you ream it. You need to know the correct drill size for your particular reamer.

You mean like this?

The killer is neither Bridgnorth tunnel or the golf course it's the Jackfield's slip which killed the line in the first place. The instability of the Severn Valley north of Bridgnorth is simply too great to even contemplate re-building the line. Even the £43k is a waste of money.

If you are going to drill out screws then the use of a left-handed drill is to be preferred. Often the drill will grab and actually wind the screw out however there is no chance that it will grab and wind the screw in - and through the bonnet!

Really! - you clearly have not observed the prototype particularly carefully.
