What is the thread used on those disposable gas bottle used for camping stoves and blowlamps I need to make a nozzle to refill small gas tanks via a Ronson valve Many thanks frazer

Hi Norm, becoming stir crazy . Just keeping out of the way until Vlad the Impaler calls The half nuts could be made to fit with a bit of ingenuity . I turned the screw around and made a new tail end and just made a different coupling at the head end. It was not a big job and on my old banger of...

The nut is the same monkey metal as the other feed screws and will be worn

Another variation

On My previous ML7 I turned it end to end . I did have access to another lathe so altering the ends of the screw was possible. I dont think the screw will go through the head spindle

Hi Scott, the engine is my own design .It is made from the junk pile and I would have done a few things differently if I had some better materials The idea is to use up some of those bits n bobs lying around and just enjoy mucking about with a wee steam plant. Also I am clinically vulnerable so...

Hi Mark, many thanks for the tip . For my small toys I use ammonia or if its small sectioned just a spray on window cleaner. I have a steam box made from a wallpaper stripper and a length of pipe . The planks on this wee boat are from 1/16 marine ply a bad choice on my part but all I had so...

Thanks Mark, I had a few problems with the hull as the planks did not want to go the way I wanted them to. If making it again I would add another two per side. She is made from scrap that has been laid around for 20 plus years and is just to get my hand back into building them again. The planks...

Hi Scott, it is simply two pins on the back of the flywheel timed at Top Dead Centre and Bottom Dead Centre. As the the control valve moves from foreword to reverse a pin on the bottom of it contacts the flywheels pins pushing the engines cylinder past either TDC or BDC. It is not perfect and...

Nice work Harold Hall also has one on his site http://www.homews.co.uk/page475.html

The urine was to fix the dye and also used to wash garments in , Although my memory is be a bit confused. The Glasgow engine is considered a national treasure although I have had to alter it a wee bit due to the scale Im working at and to make the water jacket was becoming a lifes to short...

Sorry my knowledge about the use of pee only goes back to Roman times and I certainly wouldna want to wear purple then. Pigeons make good pies and rabbits have a humped back to keep the crust out of the gravy So back to the Glasgow engine before the border is closed Keep well and safe if not...

As an aside the collection of urine was often known as the Butlers pension and clergy pee the most prised due to the rich diet, The Hartlepool story is probably just bad publicity from the makems and takems or may have been a powder monkey??? Just another useless fact from my befuddled brain

Ive attached a link that gives some insight into hard soldering https://www.cupalloys.co.uk/best-practice/ For smaller engines working at low pressures I have just soft soldered them with no ill effect. The solder will always follow the heat

Silver solder is the way I would do it. Then finish machining it cheers

No need to drill 0.2mm holes for jets ,Simply drill to 0.4 and swage the hole down around a correct sized bit of wire. My lathe wont go fast enough to drill .2mm . The loco guys have used the idea for years I tend to make 10 blanks drilled at 0.4 then swage them to the size I need On my simple...

All good stuff and very interesting The idea for the small plain flue is to keep gas velocity low allowing more dwell time. It seems to work from the rough ars££ experiments I can conduct Using different burner ideas the flue exhaust has dropped about 140c and the gas consumption has also gone...

A big advantage with a radiant burner. The velocity through the flue is slower giving a greater dwell time to absorb the heat I have recently built a simple marine centre flue boiler and comparing it to a water tubed flue of the same size the flue with no tubes heats the water faster and the...

The thread has far more attention than it deserves or would have received if the job had been done in a safe manner Horses and water comes to mind Keep well n safe

RM-MN, thanks for the reply. I have to admit I do have a carbide bit of tooling its laid in a dark corner with the spiders for soo long. Its a graver and never did get on with it Most of my machining now is for pleasure and Im happy to live life in the slow lane .Most of my work is done with...
