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.

Both my class B (8lb max weight dry) flash steam hydroplanes exhausted into a silencer to meet the noise reduction requirements. If you heard one running you would think it was an internal combustion engine. My engine ran at somewhere around 10,000 rpm to achieve just under 80mph.

Pauls (windy) hydroplane is a class A 16lb max weight.

I bought a D1-3 chuck from Rotagrip replaced the pins as described above for my 254 even managed to get soft jaws to go with it. Same chuck as the one I already had it does not have a name just some numbers.

It is see top left.

What a nice looking car it’s the Porsche I would like to own. Interested to here about the engine it’s amazing what you can get out of an old block.

It has been out of print for a long time, it only had a life of a few years.

Their site says they will take Western Union, it’s not expensive if you do it by bank transfer. I know it’s not popular but I use it to buy model car parts from Russia with no problems they won’t take anything else.

In my merchant navy days the ships captain was always responsible for the ship the pilot was there for advice. The only exception was the Panama Canal. But that was the 1970,s

I didn’t hear an output figure mentioned, would be interested to compare it against our tether car engines. No nitro just methanol and castor.

I have one at the moment I am halfway to,paying for it. It is going to my son next who has a box full of blunt cutters if you can salvage some it helps towards paying for itself.

I have a tool and cutter grinder it works well but setting it up for each cutter is a major draw back.

This where I buy my inserts from, https://www.shop-apt.co.uk and milling cutters for my cnc mill the quality and service is good. But they supply industry and a lot of inserts are only supplied in boxes of 10, some are available in model engineer quantities.

I also use Arceurotrade for inserts their own brand for me perform well for me.

10BA steel studding on eBay 300mm lengths.

Keith it’s the nickel plate that has gone rusty in places, perhaps giving it a run might improve its looks.

Keith I have a Juggernaut pulse jet complete with a battered box, it’s never been run but time has not been kind to the tail pipe.

Yes I did run at Hull, it could have been me or more likely Bob Kirtley.

Hi Hans

Very little interest on this site for the speed type modelling, the Americans have had an electric tether car well over 200 mph some very clever model engineering and electronics to control it.

The Swiss tether car guys probably have the best of both worlds a fast tether car track and a Gauge 1 local track that most people only dream about all on the same site. I have met some of the Swiss controline flyer there.
