Same with Mamod burners, the hole is at the bottom. I assume a safety thing |
Doh!
Now everyone tells me.
Well I'll only put holes in the bottom on the last two.

Just a theory guys, but surely the hole in the bottom of the feeder tube ensures that the meths doesn't rise above the feeder tube level within the wick holder. Regardless of the meths level within the main body of the burner. 
Otherwise, the wick would simply draw up all of the meths, until the main reservoire reached the same level as the top of the wick holder.
Don't know if I've explained this properly, but I know what I mean. 
If you've already committed to holes in the top of one or more tubes Tony, watch out for the reservoire level.

I'm not quite sure what you mean Yosa, but the meths level will be the same in the wick holder as it is in the main reservoir regardless of where the hole is. That's why the tops of wick holders are always level with the top of the reservoir, so that when the reservoir's full the meths doesn't spill out of the wick holder. I think!  |

| That makes sense chaps - there's more to a wick burner than meets the eye. |

I just checked the plans I have to build the guage 1 'Project' loco by the guage '1' model railway assoc and they drill a hole right through the feeder pipe both top and bottom so if its ok for their loco it will be ok for mine.

I don't think it matters as far as functioning is concerned. Obviously, the more metal you remove the weaker it will be but, if the tubes are well soldered together, that shouldn't be a problem.

What do you use to plug the end of the tube mate? Solder?

He means the feeder pipe MM.
Yosa I have a brass rod that is a snug fit inside the 1/8 inch pipe.
I will cut a small bit off and solder it in the end of the tube to seal it.
If I had been a bit more forward thinking I would of silver soldered the plug in first before I even fitted the 1/8 tube to the fuel tank but will have to settle for soft solder now instead.

The pipe that feeds the wicks? I'd have thought you would have used a wick tube as the end?

See what you mean MM, so the last wick tube in the line is also the stopper?
