| Hey Justin
Looking like your getting pretty close to fire. I think Stan is looking foward to firing it soon. Dan's track is ready for its maiden run. | |

| | Hopefully soon. There are some plumbing issues to sort out and possibly some re-packing, but it will be nice to get this out and move on to something new. | | | |

| Finally another update. The blower plumbing is complete save for a couple gaskets and some sealant, from the back. To the cavernous smokebox in the front. The smokebox itself is mounted, again save for some sealant. And the best news of all is that the boiler passed it's hydro test! It's hard to see ( I really need a better camera) but that's 200 P.S.I. on the clock with no leaks! | | | |

| Justin,
I've been wondering what was up with this project. Thanks for the update.
Do you always hydro test to 200 psig? What's the planned working pressure for this boiler?

| | Hi Steve, its been a while and I need to get this done and move on to other projects. I usually do 3x the working pressure for a brand new boiler and 2x for the yearly hydro. The planned working pressure for this boiler is 65 p.s.i. which would be 195 p.s.i. at 3x. Might be a little overkill but doesn't hurt anything as long as it's properly built. | | | |

| I think you are overdoing the testing pressures, 2 x is plenty for the first test and 1 1/2 times for retest every 4 years, this is the reccommended practice over this side of the pond, you will be stressing the copper too much if you repeat to your test presures.

| | Thanks David, good to know. I saw this as a reccomendation somewhere, but it might have pertained to steel boilers. | | | |

| | The "if a little is good them a lot is better" approach to testing (and other things) seems to crop up quite a bit, in the large scales as often as not, and it tends to come from relatively inexperienced individuals who seek a little authority or recognition or who may attempt to apply inappropriate standards (refineries? nuclear? aerospace?) to model practice. Cooler heads tend to prevail before costly construction is ruined, but not always. I know of more than one boiler which has been ruined by an uninformed and/or overly-excited tester. You will find that David's test pressure recommendation of 2X/1.5X have been the accepted standard throughout the live steam world for decades and have been proven as adequate and predictable indicator of safe condition for miniature copper boilers. As LBSC was fond of saying . . . Nuff Sed! | | | |
