wahya pics (1).jpg

Hi Everyone,

I’m new to the forum and a beginner in many ways when it comes to model engineering. I’ve uploaded some pictures of my Wahya 5g American type loco currently being serialised in ME. Unfortunately I am unable to share my dynamic simulations and videos of the completed build in paper format but there is no such limit here! Hopefully those of you interested will click onto the following links:

https://youtu.be/8I9-eJiKn1E is a video of the loco running around the RSME track. Thanks to Jadan for the editing.

this was a short video I put together for an engineering conference and shows a little 3D printing of the patterns and some backyard foundry work. There is also a FEA of the shrink fit tire with lateral forces; and dynamic simulation of the valve gear.

I hope this is of interest,

Luker

Well I for one have greatly enjoyed your articles in ME! It's good to see fresh eyes looking at problems and coming up with some very innovative solutions, using modern analytical methods.

Keep up the good work!

I've enjoyed the Wahya series too. And the locomotive looks great and runs well. But I note that you don't seem to notch the valve gear up (??).

Regards,

Phil

Thanks for the welcome everyone. Being on the other side of the pen; it's nice to hear the articles are being enjoyed as much as I enjoy writing them. Well spotted Phil, you correct I should be notching back on the track. I didn't because I was concentrating on holding the camera and watching the track (train robberies aren't unheard of in SA, no jokes!).

For interest: with the designed lead and admission I gave her, I have four notch points to mid gear (there is a gap between the forth point and mid gear). The largest cutoff only works well at high speeds with the designed lead, and at low speeds she tends to stutter a little which is expected. When not pulling any passengers she's quite happy to pull away from the second notch.

Thank you for the response Luker. Hopefully you will be able to relax without the concerns of filming etc., and you will be able to enjoy your beautiful locomotive still more.

It is a real tribute to your skills and approach and looks and sounds really good.

I found your 'pressure-gauge' article very interesting too. Following your example I am looking to source a couple of suitable pressure-gauges (10bar) from ebay (or similar) to experiment with.

Thanks

Phil.

Thanks for the kind words Phil, much appreciated.

I'm glad someone is going to give gauge hacking a go, please could you let me know how it turns out. I hope you make the pointer as well; it makes the gauge unique and explaining to youngsters on the side of the track that you can make train parts using cellphone chargers is entertaining in itself. I've uploaded a few additional pictures that didn't make it to the article, to an album. I hope they give a little more insight into how I tackled the job.
