Just read Model Boats mag for November. The story of Queen Alexandra (model), started 1996 still not completed, but has taken to the water.

15 years makes you a driven
machine Geoff!

Sorry Kim I am only a clockwork toy, 3 years on the Duke.  The Queen Alex is not mine.  My problem with the burners I found by accident, after getting the flames settled I happened to pass  the lighter over the funnel. This revealed a blue flame about an inch above the funnel so not all the gas is burning inside the fire tubes. Excess gas could build up in the bilges BANG !!! Searched the net for size 3 jets to no avail, if only I could drill a 0.15mm hole.   So it looks like I will have to make a boiler with 28mm tubes instead of 22mm as present. One more option I will try to make a gas regulator, with help from the down load section.

 On a happier note I do like  :clap the look of your steam plant Derek.   Geoff

Could you find some 0.15mm SS wire? Drill the smallest hole you can in a blank the same shape as your jets, insert the wire and use a center punch to close the hole down around the wire then pull the wire out.

Thank you Gerald for the suggestion, lateral thinking can be good. I have number 5 & 8 jets could they be partially blocked, I am thinking  :thinking . When I was working (as a carpenter)it was rumoured  :gathering if I couldn't do it with a hammer  :hammer :hammer I couldn't do it at all. Unfortunately I require 2 jets working from the same canister, so they have to be absolutely identical. Even the propriety jet had to be changed until I found a matching pair. Geoff

Hi Geoff,
I can't remember where it was but someone suggested using Watch (Jewel)Bearings for the hole in homemade jets. I haven't tried it, but the idea stuck in my head, If I find where I came across it I will post a link. I did find some size reference;
  "Melting point is about 2,050˚ C.  Low relative cost. Typically, a jewel bearing costs 20% as much as a ball bearing and 10% as much as a flexural pivot. Tight concentricities, to 0.0002 in. in most cases.  Small sizes for compact designs. Shafts can be as small as 0.006-in, diameter, but more typically range from 0.02 to 0.125-in. diameter."

Gerald thanks for the inspiration, jewelers supplies have 0.15mm drills. At a cost of course, would have to be very careful not to brake it (them).  Although its only the final exit that has to be .15mm. I have the brass hexagon rod, the die, all I need is the nerve.
Having almost finished a gas regulator, just need a suitable membrane now. I will experiment with this first. Sorry no pictures as my camera is kaput. The BOSS is buying me a good one for Christmas. Geoff

Derek. You obviously got my PM thank  :trophy you.  .039 would be near enough for me. I have found a piece of car inner tube @ 1.20 thick that is working OK.  :terrific
 I must get a camera.  :kewlpics

Still no camera got to wait for my Christmas present. ( Hope its better than the last ). But when I have it I will take photos of the gas pressure regulator. It is working well so no need for number 3 jets. A word of warning to anyone making a gas line(obvious really) be scrupulously clean. I used secondhand 1/8" pipe big misstake.  :oops :oops :41 :41 As it don't take much to mess up the jets, and nothing to clear them out. Took me 10 days to work out why the regulator wouldn't work.  :sobbing :sobbing

Well I have my new  :gift camera. :yeahbaby Because I have been a good boy, I have been completing jobs for the big boss.  :respect I hope you will consider the picture quality is much better than the old one.Derek . It shows the gas regulator. The OZ on the can is the weight when full, will weigh when empty so I can tell percentage left  Geoff

OZ represents ounces the 8 is around the side and cant be seen. I must be more careful in the future. Don't want you getting ideas above your station. Just stay  :s_cool . I may video the control I have with the regulator just need 3 hands again. Your friend Geoff

The regulator before assembly, only the car valve in place.
