Could it be this one? The forum is blocked on my computer.

Sorry to hear this. I liked his writing style.

PM Research are the first ones to come to mind.

Some of the apprentices the year above me sectioned a Gnome Turboshaft engine. We only found out in later years how much Beryllium Copper was used in its construction.

Just speculating, is there going to be a problem going from 24v AC to DC? I wonder if thats an RMS value.

Welcome Eugene

Will the results make a difference to your work or is it just out of interest?

He does mention in the notes that if you set the opening points exactly to the drawing you will find the valve close a little early.

Your name isn't Derek as well is it by any chance?

Can I say not only what a good detailed review it was but also what an excellent museum it appears to be? If I ever am up that way I will be sure to visit.

My William (almost the same design) repeatedly blocks the lower three tubes. I've taken to carrying an old flue brush with no bristles to knock the grit out. Infuriating. I've slightly opened out the blast pipe to try to reduce it happening, I've not tried it enough to gain meaningful results yet.

I've thought about including a baffle in the front of my ashpan which curves up to slightly shield the lower tubes but haven't done anything about it yet.

If I do poke the fire i try to do it stationary with no blower to prevent anything getting sucked up.

You may find what you need on this site.

Best of luck

I'm a bit nervous of holding Milling cutters in a 3 Jaw for some of the methods mentioned above, but I'm quite timid with some things.

Second vote for the Stevensons block, it does mean collets too, but those are a very useful addition to the workshop. I got my square and hex stevensons blocks plus collets from Arc too.

Total internal reflection I think its called. Something to do with making sure a limiting angle isn't exceeded.

Sounds like between us we need to form a society of Amputee model engineers! However fingers don't count or we would be flooded with vacancies.

Best wishes, it sounds like you have a good mindset. Adapt and overcome.

Take the utmost care! We need all the members we can get!

I hate to repeat what has been said elsewhere, but you really need someone on hand to assist with these things. It's like trying to learn to drive by post otherwise.

Everyone here is very happy to assist in any way they can but its quite difficult to do so via a forum. If you can speak to your local model engineering society; ours certainly has lots of keen members eager to share their experience.

Really nice work, it's given me an opportunity to go back a while and catch up with what you've done to date. Following with interest.

My previous post I think got lost. I was pointing out that wartime equipment was often unpainted or blackened to save paint for the war effort.
