More free plans: 40 pound Chinese
Plans for the M40, a 40 pound thrust Chinese style engine. Read the pdf carefully and build according to specifications. You can lengthen the intake by 2mm or so to give you a bit more room to hammer the flares, however, the plans are ok as they are. The pdf, the drawings and the print-outs were all done by Joe "GRIM" Deacon. Many thanks!

Re: More free plans: 40 pound Thermojet
I make already 2 pieces....The head with a sparkplug & the cone after the combustion chamber.I'am waiting for the sheet rvs that I command.
SOMEBODY PLEASE TELL ME HOW TO MAKE THE CONE'S!!!!
It stays a really hard work for me to make them.I have a roller machine turned by hand.But they are never nice round..........and they misform by welding.
Every pule-jet I make is very hard word & they are never beautifull!!

Re: More free plans: 40 pound Thermojet
als de buizen vervormen na het lassen kun je ze altijd weer recht hameren. als de buis bijvoorbeeld ovaal is geworden kun je een houten, vierkante balk gebruiken om het ovale gedeelte weer recht te hameren. Voordat je gaat lassen kun je ook proberen de buizen zelf al wat ovaal te drukken in de andere richting zodat de vervorming bij het lassen ervoor zorgt dat de buis weer rechtkomt.Barry wrote:I make already 2 pieces....The head with a sparkplug & the cone after the combustion chamber.I'am waiting for the sheet rvs that I command.

als er deuken of oneffenheden in de buis zitten na het rollen, kun je bijvoorbeeld een bezemsteel gebruiken om de deuken eruit te krijgen en een stuk hoekijzer om de overdreven bochten eruit te hameren.
Heb je foto's van de onderdelen waar je het moeilijk mee hebt?

For people who want to build this engine with steel with a diameter different from 1mm, or for some reason don't want to use the patterns, here is a pdf file with the angles for the intake Done by GRIM

Hello Guy's,
So far I'am already.Now I gona to make the holes for the intake's & so I weld them.Than I weld al the rest.
Than just make that stupid BIG cone!!!But I will cut him into 3 pieces,so it will be much easier to rool them.
Here a picture from where I'am now.Sorry for the ugly weldings,but I'am not a good welder , but after some sanding there is nothing to see anymore.
Greetings
Barry

Re: More free plans: 40 pound Thermojet
Nice work so far!
Re: More free plans: 40 pound Thermojet
Good work man, she's shaping up nicely! I can't help but notice that you have convexed (dished out) the endcap. No worries though, won't make a lot of difference. As for the welds: better then mine!

Re: More free plans: 40 pound Thermojet
@Metiz : what's "diched out" ????
The big cone is also ready & welded.......All my muscles are very hard right now.
But big disaster......I did something wrong with the exhaust,he is 162mm.Now I have to cut the piece and do again.But that will be not for today.
here a picture.
