|Thread: Q1 errors/changes listing?|
If you look at 'Bolier Bushes' you will find some amendments to the Q1 bush thread sizes and more importantly to the requlator steam fitting bush on the front tube plate. This needs to be 22dia not 18dia.
|Thread: Boiler bush sizes|
Many thanks. I will amend my copy of the drawing.
Sorry to be a pain, but on the steam pipe bush on front tubeplate,Drg Q1-008-L006 & L007, the dimensions are 18m dia with 4 holes 6BA on 13mm pcd. On the regulator assy drg, Q1-008-L008, they are shown as 22mm dia with holes on 15mm pcd. Can you confirm which are the correct dimensions.
22dia would seem to be the correct size.
Many Thanks Nick.
I have rev 2 of your drawings Q1-008-L006 and L007 as supplied by Polly and cannot find the flange depth for front tube plate, throatplate etc. Also fire hole is not dimensioned other than it being 24 long.
I'm having the boiler made for me, so may have more questions in the future.
Again, Many Thanks.
Thanks Nick. I will amend my copy of your boiler drawing. I think, also, that the dimension for the depth of the flanges is missing. I would think they are are about 10mm. Can you confirm.
The drawing for the boiler shows the thread sizes for the Blowdown, Clack, Water glass bushes and fusible plug as 1/4" x 26 tpi. Commercial maufactured Clacks and Water Gauges are normaly 1/4" x 40tpi.
Is there any reason why they can not be 1/4" x 40 tpi?
