Well, what a nice day!

Wednesday is always a good day. That is when our model engineering group has its weekly meetings. Mostly a 2-3 hour informal gathering around a large table, chatting about current projects, new tools, the weather, rarely politics or religion. Coffee. And once each month a more formal evening meeting, involving discussion of club business, “models on the table” and usually a guest speaker. Today was the informal 2-3 hour chat variety.
I used the opportunity to ask about methods of making a rectangularish water tank for the Trevithick dredger engine, riveting, folding brass, caulking with solder, etc etc. And Stuart T, knowing that I had to make a stainless steel compression spring for the safety valve of the Trevithick, brought in his tools for making springs.
This is one of the tools. It was designed by Dwight Giles, and made by Stuart.
Published in Model Engine Builder 2007.
The tool is mounted in the lathe tool post. The V supports the chuck mounted mandrel, and the brass washers apply drag to the spring wire. The lathe threading gears supply the pitch to the spring. Looks excellent, and I was hoping that Stuart was intending to lend it to me. Otherwise I would make one of these tools. But why were there two of the tools? “Oh, one is for you! I was making one for myself, and it was just as easy to make two.”
Not the first time have I been the recipient of Stuart’s generosity. When I make the spring (soon) I will take some pics, and post them here.
Later in the meeting, Swen Pettig, recently returned from a fabulous trip to Scandinavia and UK, called for shoosh, and stood up to make a presentation. Some people knew what was coming. I didn’t. But in “recognition for writing about his model making” (now my ears pricked up), Swen had picked up an item in the UK which he thought I might find interesting. Knowing of my current interest, some might say obsession, with Richard Trevithick, he had looked for and found the following item.
A Two pound coin. I did not get the significance, until I looked more closely. Holy Shit! That is a Trevithick engine on the coin. The Pen-y-Darren railway engine if I am not mistaken. Made in 1804. And using many recognisable features which are in my slightly later dredger engine. The coin was minted in 2004, 200 years later. Wow!!
I did not even know about the coin until today. But I am honoured and very grateful for this lovely gift and thought, Swen.
One wag suggested that I should make another gas knob for the engine, and mount the coin in the knob. (thankyou for the suggestion, President Brendan. I will do no such thing). It will be a valued possession.
Incidentally, the reverse of the coin has an image of the Head of State of Australia.
I love that spring tool, are there a few more images from different angles available? I would like to make one.
My spring making method is to don my leatherette welding gloves, drill a hole in a mandrel of the right size, snd hope my fingers do not get in the way 😉
Nice find that coin, I bet it blew your mind.
The other day a friend sent me some pictures of a nice five inch gauge locomotive his grandfather made.
The next morning I was in the bog getting my daily read. The book was s history in pictures from 1910 to 1935.
What did I see? Yup a picture of the same locomotive! My friend was quite excited to identify his locomotive. BTW IT WAS THE “Flying Scotsman”,
Thanks for sharing

Yours is obviously a great gift and is to be treasured, but there was also a proof coin struck in silver, which might look nice displayed on the engine mount?
Search ebay for 2004 £2 STEAM LOCOMOTIVE SILVER and you’ll find a few, there are also uncirculated (UNC) base metal versions quite a lot cheaper.
