Anything over 250g requires registration. But some regulation applies to those less than 250g you need to wade through the regs.

I have just ordered some bits and bobs by phone for collection tomorrow when I am passing, with no problems.

For me this is good news I have an interest in all the magazines, but their is not enough content in any of them that interests me to get me to buy them. I hope they get put on Readly.

The other option is to find a mentor who is prepared to share his skills. I have been lucky I have friend who lives 15 minutes away a very skilled engineer who spent his life as an engineer and designer.

You will also find people who are prepared to help in specialist areas of your hobby and share their skills and knowledge.

That’s the usual way to turn tapered small diameters just need a sharp tool that’s on centre.

My father was a working clockmaker and made predominantly skeleton clocks from the simple to orrery,s in batches of 5.

When he died his tools were shared out between us three brothers, as part of my lot I got a ball pien hammer with a short handle it’s turned out to be the go to hammer easy to handle and heavy enough to do what’s needed.

Have you tried the Component Shop. https://www.componentshop.co.uk/leads/connectors.html?p=8

Yes it’s normal, adjust then tighten check centre height of the tool if wrong repeat until right. You will soon get the hang of it. Once the tool holder is set for that tool it stays that way. Don’t forget to lock the adjuster.

What hp are these blown engines making be interesting to see how it compares to my lads turbo mini with fuel injection.

Try this company very helpful with lathe chucks etc. http://www.rotagriponline.com

A very nice locomotive well done.

They also have twin pack epoxy resin glue 5 minute and 20 minute, I have used it before good quality stuff all stocked up now.

I make a lot of thin parts, steel rules make good parallels over the years I have amassed a good collection of them.

You can buy the valves ready made that will fit the Dynajet and it’s clones. Hobbyking made a copy of the dynajet it runs very well with a little work. Mine has performed well in a control line speed model 120 + mph.

Have you looked in Brownells They have a lot of torx screws.

I use 8.8 and 12.9 regularly sharp hss works well and if you want a really good finish do as Jason B says. Use good quality bolts as a source of material and the same goes for the inserts if you use them.

We had a vacancy for a maintenance engineer apprenticeship in a plastics factory. Three budding hopefuls turned up all similar academically, the practical test was to wire a 3 pin plug complete with wiring diagram attached. Only one managed it and he got the live and the negative the wrong way round but he did spot it in the end. He got the job.

If you have a look at the Expermental Flash Steam book, on page 171 you will see a drawing of F Jutton,s engine as part of the piston valve it includes to allow the engine to exhaust on the up stroke. It’s quite an interesting engine with the quick return motion to the piston valve.

What about a new Indian made old British bike probably no spares required.

Have a look at Frank Jutton,s flash steam engine for TNT that has a piston valve and from memory it has a pressure relief as part of the piston valve. It’s detailed in Experimental Flash Steam book. I have built his engine but struggled with the piston valve seizing. I now have his boat TNT and power plant.

To solve the seizing problem I built a poppet valve engine, my steam was hot it turned the top of the engine blue.
