Re: Llewellyn Loco Works #1

Its rare to see that level of dedication in the larger scales let alone 16mm, I look forward to further writings. I am also going to steal that jig for cutting bolts to the same length, simple yet brilliant. From a previous ME magzine article, to me making my version, sharing the pics, then you or ...

Re: Llewellyn Loco Works #1

Wow!! I'm quite exhausted from reading this thread. You really must be congratulated on the effort that you have put into this project, not least the actual photographing and recording of each stage. That alone is worthy of a 16mm Oscar (is there such a thing?). There was me quite proud of my humbl...

Prototype slide valve. Gunmetal. https://c1.staticflickr.com/5/4352/37005942692_4d993ea599_b.jpg Rubbish slitting saw, I have tried two and they are rubbish.

Re: Llewellyn Loco Works #1

While all this is going on I am checking the valve gear. Now please do not get me wrong, Brian's books is marvelous and a great source of inspiration and information, the big difficulty I have is the valve gear and layout. The book does not provide a valve gear/motion general arrangement drawing tha...

Re: Llewellyn Loco Works #1

For the steam chests, missing dimension for the off set cover hole for the admission passage. I nearly missed this and I would have been cursing if I did. If you look at BW's drawings you can see the off set hole lines, but no dimension or text. I am not going to use bolts, after only using 4 cover ...

Re: Llewellyn Loco Works #1

This is not going to be a fine scale working model, I leave that to the incredible Cherry Hill. It is all a process to learn and arm myself with the knowledge and tools to make a super 5" gauge QR C17 loco in the years come. However cheese head screws on buffer beams looks like a gooba dripping from...

Re: Llewellyn Loco Works #1

To trim and finish off the BA screws to the correct length and to give a nice finish to the trimmed end with a small radius I fussed for a whole weekend Sunday morning making a special tool. This was inspired by recently seeing an article on clock making in an old Model Engineering mag in my library...

Re: Llewellyn Loco Works #1

A quartering jig is required Refer to B W's design. Ponder, I change a few dimensions and add lock nuts to the axle end screws to firm up the wheel assembly while the Loctite does its job. https://c1.staticflickr.com/5/4242/34434919483_a42d7ba2b2_b.jpg Lock nuts https://c1.staticflickr.com/5/4255/35...
