Re: GWR Steam Railmotor Chassis

I have managed to make a jig in Tufnol with a 1/8" hole for the axle and a 0.70mm hole at the correct spacing for the crankpin, but unfortunately the holes are not vertical, the root cause being the alignment of my mini drill in the cradle of my home made stand. However it has made me realise t...

Re: GWR Steam Railmotor Chassis

Tim, thanks for the encouragement. You managed to give me a nudge in the right direction. 1st attempt, using a piece of steel strip failed when I broke the 0.70mm drill when almost through the second hole, but anyway the holes were not accurately 2.60mm apart. I then had a brainwave for getting the ...

Re: GWR Steam Railmotor Chassis

Hi Tim, Thanks for your suggestion. I will give it a try, but without a pillar drill don't hold out much hope in getting the holes vertical/parallel. I've also found this suggestion:- https://www.scalefour.org/forum/viewtopic.php?f=20&t=2019&start=50#p18358 The required crankpin throw is 8&q...

Re: GWR Steam Railmotor Chassis

I have recently received some 3'11" wheels from Alan Gibson for the motor bogie, but they are without crankpin holes, just an indent on the front surface as a position guide. It looks as though I am in need of a crankpin drilling jig as described by Will L here https://www.scalefour.org/forum/v...

Re: Structures for South Pelaw Junction

A Nut & Bolt can be undone (& re-used) much more easily than a rivet?

It is probably easier to do a nut & bolt up to a desired torque force, thus stretching the bolt by the desired amount in a more precise way than a rivet?

Rivets are quicker?

Re: Exactoscale switch chairs E4CH 501A

Of the 5 switches you are trying to make, how many are Right Handed & How Many Left-Handed? If they are all the same hand, then you would need 15 chairs of the same type for that hand, but you will only have 10 chairs of that hand. That is if you want to conform exactly to the diagram. It seems ...

I would second the use of polythene if you are using PVA woodworking glue. Assuming that you are laminating a number of layers of thin plywood, you might like to try using atmospheric pressure instead of clamps. In the past I have successfully used Clothes Storage Vacuum Bags to act as a "Bag&q...

Re: GWR Steam Railmotor Chassis

Hi Jeremy,
On subject of wheels, for the Railmotor engine chassis I assume we will need 2 pairs of Alan Gibson 4S47L (for P4), but what should we order for the trailing bogie?
Are they 14mm Mansell or plain disc coach wheels?
Would help to know as I might as well order them all at the same time.

Slightly off topic, but Interesting glimpse of the front of a 4-COR MBT in the 3rd picture down of the KWVR posted by adigill.

The good news is that I've found the CopperEase packaging and it's good for -40 to +1150 degrees C.
The bad news is the packaging is empty!

Hi Jeremy, Thoroughly enjoying your progress! With regards to the solebars:- Do they have separate overlays? If so what thickness do you use for the overlays? Is the river detail etched or punched from behind? If punched from behind may I ask what tool do you use to get such consistency? Steve
