Re: Edith locomotive
First test cut of chassis parts. Mainly just to see if the bend slots are in the right location. Wheels will be bigger - these were just what I had in stock. More tabs and holes to sketch in. Might be able to make it a few mm narrower.
The frame stretchers conveniently fold by hand and it's all assembled using M2 nuts and bolts so no need for any thread cutting. Cuts down on production cost.
This could be used with an electric motor should one so wish.

Re: Edith locomotive
Looks well executed and I like the fact it is not made out of brass.
What sort of body are you thinking of making for it?

Re: Edith locomotive
No plans for bodywork at the moment but some sort of tram or logging loco look would be the obvious choice. I can easily cut different types of bodywork on my lasers or people can make their own.
This is mainly about designing a platform for a low budget steam loco and give people the opportunity to buy as few or as many parts as they want.

This is looking very good and I hope it proves a great success.

Re: Edith locomotive
It might be hard to tell from the picture but the chain used is steel roller chain, not Delrin chain. Sprockets are also steel.
Wheels will be 35mm over the tread.

Re: Edith locomotive
Covid-19 has a big effect on two of my largest customers as they sell a lot of their products at craft fairs. Consequently this affects my business and money is likely to be in very short supply for the foreseeable future. This means I can't order wheels and other parts that are needed in order to progress with the kit.
I suspect this hobby will get hit quite hard - when the financial crisis started in 2007, businesses catering to the hobby market were the first to get hit as people stop spending on hobby in times of uncertainty. I had to close down a once thriving R/C hobby online shop back then.

Re: Edith locomotive
Simple and affordable steam locos are always of interest. Not only does it allow existing garden rail types
to experiment with maybe designing their own bodywork and 'kitbashing' to improve their skills but may entice others into the world of small scale steam.

Re: Edith locomotive
It will for sure. I just don't know when. I was about to order parts this week, but a sharp decline in orders means I have to put it on hold. I won't be able to pay myself any salary this month. Luckily my wife is in public employment and as such is guaranteed pay.
Re: Edith locomotive
I was wondering, where do you get your sprockets and chain and what is the bore of the sprockets? It looks like 3mm on those axles, but I'm wondering if you've had to turn up a sleeve or something to get them to fit.

Re: Edith locomotive
I would suggest it is 'Delrin' chain and sprockets, several suppliers advertise on ebay. I have used it many times and it is perfect for our scale use.
p.s. welcome aboard!

May I also ask about source of chain/sprockets.
In my trawlings, 3mm pitch roller chain seems phenomenally expensive.
Delrin is too flimsy for my garden line, constantly stretching and eventually breaking under load.

Re: Edith locomotive
Thanks for correcting me, I see the information was given earlier in the thread and I missed the point completely. I am not an engineer and passed over such detail with little interest. I have used Delrin chain and sprockets myself and found it perfectly sufficient for my needs, but my locos are made of HIP and don't haul heavy loads so in that instance I find it works.

Re: Edith locomotive
My experience with Delrin is on an Essel chassis under a converted HLW Mack body.
It has the grunt to recover gassed-out steam locos, but the Delrin, as mentioned, progressively stretches.
Eventually, a link can be removed, but the process continues. After removing a second link, the chain breaks.
So, replacing with a new chain starts the process again.
I spoke to Stephen Lacey, who said I'm working it too hard!
I'm a bit dubious about Roundhouse saying their battery locos are equivalent to their steamers.
Hercules uses Delrin.
Ladder chain on sprockets is a little too coarse.
The roller chain used on the SloMo device looks ideal, but I can't find its origin.
Something similar is available in USA, but around £90/foot.
