Re: Aster Berkshire prototype
Keith, Thanks for the tip about the connection of the gauge siphon to the turret. I have to agree with Geoff and Harry about the probable impact on a miniature steam gauge. Siphon connection point, and knowing actual boiler pressure, is probably more critical when pressures are much higher and the gauges big enough to provide precise readings. Of course I have to agree with them, because I've gone ahead and planned to attach the siphon to the steam turret on my under-construction 0-4-0. Parts are made so I'm not changing it now. The story that I'm telling myself is that the relatively low planned boiler working pressure, and hoped-for boiler steaming qualities, will make it a non-issue. Geoff's and Harry's comments reinforces the story. Steve [EMAIL PROTECTED] wrote: "... the steam gauge is getting it's feed from the turret? I would think that to be a poor spot to measure the boiler pressure, since fluctuations from using the blower, whistle, and what not would give an inconsistant reading at best?"
Re: Aster Berkshire prototype
Hi Keith, I didn't notice, you brought it to my attention. I suppose the proof will be in the pudding, when it is running but I am sure the gauge would reflect a slightly lower pressure and fluctuation as you state, but as Harry noted: " I don't see that as worth worrying about, especially when you're doing well to get within 5psi of true reading with the typical miniature steam gauge anyway" I usually just glance at the gauge, if it's somewhere in the middle that's OK, but if it's dropping dropping, or rising rising, then I take action--like panic action!

Re: Aster Berkshire prototype
Hi Jeff, Tony and Geoff, Did anyone beside me notice that the steam gauge is getting it's feed from the turret? I would think that to be a poor spot to measure the boiler pressure, since fluctuations from using the blower, whistle, and what not would give an inconsistant reading at best? I know it has always been considered essential in the larger scales, to extract the steam for the pressure gauge, from it's own dedicated tap on the boiler, as well as having a syphon to insure that "live steam" did not enter the Bourdon tube, and affect the temper of that important item. There is a kind of syphon there, but still, taking the steam for the guage from the turret is unusual, to say the least! Keith Taylor Jefferson, Maine
Re: Aster Berkshire prototype
Hi Jeff, Impressive. I particularly like the Johnson Bar quadrant control. No more fiddling with the screw reverser. Also with eight coupled flanged drivers, you may need the recheck the rads on your new track before you finish it off, this engine is not a flangless C16!.

Re: Aster Berkshire prototype
Thanks Jeff, Yessir, some levers--you can do the radio control!!--That'll keep you out of mischief for a while, even cause a nervous breakdown? Geoff.
