Boilers

(1/1)

Hi PD’s & welcome to 2006 – spent the holiday [yesterday] fabricating a base for Decoy’s boiler – the 4 x feet pads will be epoxy grouted & screwed to the boiler room  floor which will the allow the actual boiler mounting base & boiler intact to be removed via the 10-32 [3/16” UNF cap screws]  - naturally I have copied/complimented the boiler design to the base with brass rails on the blackened base etc

As the manufacturer well noted to me a few months back ‘keep the boiler room free, as [it, she {the boiler}]  will need lots of air’ – well yes I have done this with an open boiler room, but wondered if I could improve boiler combustion by adding a forced draft air scoop to scale just like the original PS Decoy  

So my question is ‘with the vertical & horizontal tube components being 0.4375” diameter, however in OZ we only get metric [not Christian] size drills – is it better to drill an 11.0 mm diameter hole in the boiler & try & panel beat the 11.11 diameter tube to fit? – or drill oversize 12.0 diameter & use gap filling SUPER GLU prior to next lighting of the boiler & pressure test??  - [sorry - just kiddin Sandy]  

regards Derek  

Oh BTW1 - the plastic cloths pegs were just to get a bit of true alignment for the snap & will be dispensed with when I solder the air tube into the boiler
Oh BTW2 - the boiler air scoop is totally functional in that what ever differential pressure is created will displace this [air] to the lower boiler room floor – I think [courtesy of Messer Bernoulli --------------  P1V1 = P2V2?] or is my memory fading?
