1:24 Hook & Chain

A detail I've been wanting to do for a while are the Chain & Hooks, After playing with a few tests I came up with an answer, print everything separate, paint while still on the print raft. 

The next step above is to pop off all the components & attach to a board with double sided tape, then paint the unpainted side. I failed to do this step with the first 3 sets! so will have to touch up later.

And the result is a multi colored nightmare, but will easily be fixed. Only 2 chains need a fine cut with a razor on 1 end to complete assembly.
Overall it looks ok to me, the chain is quite free to move, although couldn't hold a train together.

All 50fters painted in Coronation Red, Also the first of the 47/6 carriages to get painted with a more correct black roof. Space is becoming more of an issue with each passing week.

1:24 Wab revisted

The 1:24 Wab finally gets some attention, the chassis is a bachman $50 job, with everything but the siderod,wheels gears & motor thrown away least I be tempted into something plain and ordinary.

Since the picture alot of sanding & filling of the cracks in the lamination occured.
The front weight was eliminated via a hacksaw, as well as the number plate extrusion, which I think I had the idea of applying a decal and all would be good which in nz120 worked but in 1:24 not so much. also added were the cab floor, rear bogie at correct length, rear frame & driving gear. Still to add the lifting arms.

1:24 Wab, bachman chassis with an early test of the running gear, lifting link etc still to do. A bit sloppy at this point. I will be re-printing a slightly longer main rod to correct the crosshead position. The real crime is the placement of the crosshead guide 3mm offcentre to allow the thicker driving wheels & siderod to clear the crosshead guide when in motion.

1:24 Ww Class

A new project thanks to the aquisition of suitable low cost LGB chassis on trademe will see a few Ww's & in the future a C shunter. And if I alter the wheelbase perhaps a few more classes. .

The chassis is a  LGB Power Truck for the LGB Locos 20750, 21750 and 20755
The chassis cost about $150 for 2 on trademe. Quite common it seems.

After printing plans in 1:24 scale, design work when into the chassis first, Printing the wheel centres for the existing wheels & a false centre wheel.

A few days later and the bulk of the body & detail parts are printed & painted. The body still needs further finer sanding but progress going well.

Next version will be the reboilered Ww, with a far more impressive look.

Ww makes another test run

The Wab is in focus, with all working motion & mounts ready to print. The bachman chassis completely striped down to nothing except the main frame & gearbox/motors/wheels. The rear chassis can now be reprinted to correct length. Body is to be sanded down once again & repainted. The Wab will benefit from the Ww detailing & work on the Ab can finally resume & finish allowing the C shunter project to begin.
