Looks like your are going great guns Hobby, I've really enjoyed following your progress. Nick

Hi Tony, Thanks for the finishing info, I feel some finishing experiments coming on. Thm: What are you going to make next then? I'm thinking of a double acting cylinder for my next engine. Probably a wobbler style. Nick

Hi Tony, congratulations on building a nice runner. I Like your ball link solution to get all the axial movements needed on the valve push rod. You certainly got yourself a very nice gleaming finish on the parts too. How did you do that? Mine is still in the raw state awaiting the finishing...

Hi Tony, It's coming along very nicely, not far to go now and you'll soon have another engine in your collection. Nick

Looking great Zee, If you want the front wheels to turn too whilst the locos on the test track put an elastic band between the rear front roller and front rear roller, that should sort it. Make a small grove for it in the middle of each roller if you want to be really flash. Happy steaming, Nick

Yep know the ones you mean, thanks Bob. Nick

Thats very nice work Kvom, all the bits look very nicely made. Hope you get it running before your trip, my money is you beating your deadline. Thm: Nick

Looking good Zee. I'm sure it will just be a small step to getting it running on the track now. I think joining the two engines together as Bob says would defo help the running. But it might also cause a problem going round tight corners as the wheels will be turning at the same speed...

Thanks for all the kind comments chaps, glad you liked it and the sound it makes. I agree you Dean viz the original McCabe linkages, they were definitely clunky and needed some better engineering. I still think there is plenty of room or improvement over mine though! Smaller with smaller screws...

Yep I'd second that Pete, lovely work, maybe one day if we keep trying! Nick

You made a smashing job of that one BV, a really nicely presented model. Sounds like it has gone to good home, I've found that giving something away that is truly appreciated by it's new owner is always a nice feeling. Nick

Zee, If you haven't got lock tight a dab of super glue will do just as well. BTW sorry if the name "cotton wool" foxed you, I don't know any other name for it, so what do you guys call it then? Over here it comes in various formats. Nick

Looks great Bob, I like your finishing, what sort of paint did you use? Nick

I not been able to orgainse myself to get much shop time this last couple of weeks and when I did snatch a few moments I didn't have the camera to hand. I also felt that the link cutting was not really of much interest to look at, well that's my excuse and I'm sticking to it, sorry or the jump...

Great job Arnold, I'm really enjoying your approach to getting the job done and I'm learning loads of useful stuff from you, thanks for sharing. I've not tried heat treating to harden metal yet, got the workshop series book on it though, so will definitely give it a try in the not to distant...

Dean, I think you can use cotton wool for this task. If I recall correctly I think that it what my Mamod steam engine used under the mesh. Nick

Hi Hobby, I'm very new to machining. That's an interesting way to make an eccentric part, I'm enjoying your thread and soaking up your ideas. Thanks Nick

Hi Arnold, thanks for the info on how you did the internal threading, now I see how I should have done it! a light bulb on moment for me :idea: I've only made one internal thread to date, a fine thread for an OS 91 FS aero engine exhaust extension. I used an upside down tool, ran the lathe...

Great thread Arnold, I'm enjoying watching your progress. I also have a boring head on the to do list. Nick

Hi Orjan, I use a transwave rotary convertor for my three phase machines. You just connect one side to the mains and it makes 415V three phase at the outlet. Just wire it in and your good to go. It does make a noise as it has a running motor. But it can work several three phase machines at the...
