Axle boxes sliding between the horn plates. I want to try a leaf spring arrangement, if that fails it will have to be the usual coil springs on top of the axle boxes.

I was recently re-watching the 16 mm assoc videos, I loved your DVLR films they were magic :-)

That is the only loco chassis I've ever seen in any scale that could not look any better by fitting a body. Its almost a shame to cover it up.

Thanks Andy, that's great.

There will be plenty of works to see through the cab doors. I didn't manage to keep everything below floor height

Milling the axle box slots out of the first frame side.

Here's the new horn plates in position on one of the frames.

Front

Back

My project this week is to make some axle boxes.

Here are two new axle boxes. I shall think about the springing and the keeper plate before I start on the other frame.

I had to use coil springs as I couldn't fit leaf springs in.

Now I have to do it all over again for the second frame

Finally the chassis is rolling again... I had to modify the clutch actuator shaft to allow full travel on the front axle boxes (the wheel flanges were contacting it) that took three days after I had worked out what to do! I've switched the fasteners to mushroom-headed screws, I think they look better.

I need to make slightly longer axles now as the axle boxes stand out further than previous bushes.

There are a lot of no longer used holes in the chassis that need filling...

Very smart. Ive always wondered - what is the best way to fill holes in the frames?

Well, I've managed to fill 4 with some more screws.

Here's a cover for the lower gears, I could imagine that vegetation would get crunched up by the large 1st gear.

The cover fitted.

Looking down on the cover, we could fill it with oil too.

ah right - just tap and screw in a bolt. With regards the protector/ oil bath - do you think a drain valve for changing the oil would be required or would you syringe it out?
I can't wait to see a video of the finished thing!

Well, at the moment I think we'll do without any drain and just apply oil to the gears before a run.

I can't wait to get it running too. Just need the on-board fuel tank and a new exhaust system. I could fill the gear case with excess castor oil from the exhaust system that doesn't go into the first gearbox, then it could finally overflow on to the track.

Thank you sir!

I just love the proper engineering and thought that has / is going into this loco and would love to see it in the flesh. Just a shame your not local!

Thank you! I'm just a click on the keyboard away.

Here's the footplate, all one piece, lots of sawing and filing.

It weighs in at 3.4 Kg (7 lb 7 oz) now

I had a big shock when the cab was mocked-up in card today, it's enormous!

Slow progress recently. Ended up cutting out the cab pieces by hand after wasting time and money on a scroll saw. Then spent a week waiting for a metre of 1/8" brass half round beading to arrive; to edge the window openings and doorways. The metre length wasn't quite enough, but the front and both sides are done. I've got some more on order for the rear sheet. It's quite an enjoyable process soft-soldering the beading. The most important part is annealing it first, otherwise it is far too stiff.

I need to have the superstructure finalised so that I can progress the exhaust, fuel tank, and controls.

Well, the cab is nearing completion. All the beading is on. It is time to make a gentle start on the bonnet.

Here we are, I've bent up the bonnet in the wood vice. I like the end-on view, it's got that menacing look of the truck in "Duel" (I could put some battered old engine nameplates along the buffer beam of victims, lol).

Superb work - looking good - can't wait to see the finished product.

I have watched this thread from beginning to present and up 'till now have nothing to contribute to the project..... but I must say I am in awe of your engineering skills, combined with the infinite amount of patience you have shown in developing this loco.
Even your workshop is neat and tidy..... I must lie down now!.

Thanks chaps. When I was younger I had little patience, let's hope I keep it up
