Thread: 1/5th Scale Peny-Darren 1804 Locomotive

A sight to gladden the heart!!!!

Chasis rebuild Number 3. There was a bow across the chasis and one of the wheels was lifting. Rebuilt the support concaves. Had to remove the front pillow block bearings (destroyed) and remade them. You can see in the photo that the chasis is now levelled up and squared. Hopefully that is it. Painted the geared wheels. They look ok as cast iron colour. No work on Peny-Darren tomorrow - we are looking after our 2 YO grandson.

You are a perfectionist for sure! I really admire you work. I wondering if the problem with the axles in post #136 was the direction of the grain in the wood. It was running vertical instead of horizontal?

Shame about the chassis breaking but at least you have managed a remake

Yes - Totally agree - another error and oversight on my part. Thanks for your comment - its appreciated.

Keith< I know you have the chassis under control now but have you ever thought of
using a jig for this sort of problem??

I really love this build. There is something that grabs the heart and the mind with this ancient machinery.

Cheers mate, artme.

Artme,

No I hadn't - great idea. When I build the Stephenson's Rocket it will be one of the first things on my agenda.
Thanks for your support.

A bit of fiddly stuff today. Did a bit more on the chasis. Made up wheel lubrication system distributor and then started fitting the oil feed lines from the pump to each of the pillow block bearings. I have run out of 1/8 copper tube enough for the third line but just miss out on the fourth. Bit of a miscalculation. Amazing how much is used in 4 separate runs of tubing. Pretty happy with today's work.

Really neat work Keith.
Way to kool for school

Just when I think you are almost done you add new cool stuff! That is come awesome looking plumbing you are putting on there. I didn't even know they made copper tubing that small.

Thanks PLD,

I don't think they had copper tubing in 1804, they used steel pipe, but I think the copper tube adds some contrast. I have polished the copper tube and then painted with a clear acrylic spray so it doesn't tarnish and stays shiny. Probably not prototype, but that doesn't really concern me. Took a bit of searching to find the 1/8 copper tube - plumbers don't have it. Found it at a specialist engineering supplies firm in Geelong.

Fitted the third lubrication line. Difficult to get the bends correct. Will fit the 4th when I get more copper tube. Did more work on the chasis today. The Peny-Darren pulled the trucks and people on it's first run in 1804 with the locomotive in a configuration with the stack facing the load (in other words it looked like it was going backwards). I have fitted the drawbar to the chasis and inserted a protection plate for the boiler. The pin will sit vertical from the drawbar and the connection to the tender will be via a large oval ring (like a very big chain link). Also painted the free wheeling wheels "cast iron" grey.

Fitted the remaining lubrication line today and then I thought I would assemble the loco to see how it looks. Items not secured - pretty much just sitting there at this stage. I was not happy with assembly. The drive shaft gear does not engage correct mesh with the idler gear. The Idler gear meshes well with wheel gears. I decided to make a new drive shaft gear. The diameter needs to be increased by 15mm to mesh to my satisfaction. However, the gear pitch needs to remain the same. I have calculated that the gear needs to have 21 teeth not 20 as original to compensate for the gear size increase. Back to gear making tomorrow. Photo shows assembly - front and rear. I have put a bit of 25mm round aluminium to show where he drive piston will be located. The 12mm on either side shows where support shafts are located. The setbacks are challenging and makes me use my old engineering background (Good Fun ?????)

Looking fantastic Keith.
It wouldn't be half as much fun if it was all straightforward!
