Judith Edge Ruston 48DS - Bonnet.

I started the bonnet by rolling the top part around a broom handle;

Then I filed a radius on a piece of wood strip to fold the smaller edge radius;

Held in a vice;

I coudn't use the vice to form the other edge so I used my Bug;

Ready to be soldered up;

I bolted the body to the footplate to keep everything square whilst I tacked the assembly together. I then removed the body from the chassis for final soldering.

Grill and doors;

The grill has half etched holes in the corners, punch these out and the rivets locate in half etched holes in the rear of the front panel.

The doors are half etched, there is an etched line on the rear. I folded the doors along this line seperating them before soldering in place. This meant taking a little more care to ensure that the two parts are aligned, but I think that having the two doors as seperately affixed parts looks far better than soldering them in place in one piece.

 

I've left the doors off my loco for the time being, so I can use it to check clearences around the mechanism when fitted;

Main soldering done with 188 and the Antex, grill and doors soldered using 145 using both the Antex and my RSU.

Nice work, Paul.

 

Do you think that it would be possible to roll the top curve without a vice? The Impetus 15" Hunslet had longitudinal half-etch lines to permit easy rolling.I guess with these wee beasties, there's no chance of that!:) I think for the Impetus 48DS, (it was 20 years or more ago..) I marked the midpoint of the bonnet, and tack-soldered the end plates with 60/40, then used my pinkies to caress the wrapper around and down.

Thanks for the comments (and the likes).

 

Jan - there are half etched lines to aid rolling the corners, have another look at the first two pics. (click on them for a bigger image). It could be rolled without a vice, but for some reason I chose not to anneal the bonnets this time. Remember that Mike and Judith use .015" brass for their kits, most other manufactorers seem to use thinner gauge material. On my A1 Models Rustons I did anneal the bonnets before forming. I guess I just like to try different methods from time to time.

Ach. Nurb. I Missed those. In my defence, I plead lateness, tiredness, and all-round, fully paid up idiot-ness. Keep on keeping on.

I should really have mentioned them Jan, and they're not that easy to spot in the photos.

There is a rear bonnet former supplied in the kit which butts up to the cab front, however its unnecessary (stated in the instructions) so I didn't use it. I should have mentioned that as well...

The part in the first two pictures looks to be a different colour to the other pictures. Is this because it has been heated/annealed before bending, or is it simply a trick of the light?

A trick of the light Dave.

I have 3 lamps illuminating my workbench, any combination of which are used for photography depending on how the light falls on the subject.
