Not a very builder friendly design! Bolted flange and gasket would have made more sense than a silver soldered AND threaded collar/threaded stub. Not very nice casting work in that area either. I assume the stub part of the box gets the male thread? Can't tell for sure from the photo -- is the box aluminum or cast iron? And what are the box dimensions? Is it a tapered thread, or a straight thread with gasket? Oh, yeah, now I can see in the drawing the stub is male threaded on the outside. The brass ring thread is also stopped, another pain. It bears against the casting to seal -- so it's probably a straight thread. I hope the casting can be cleaned up enough to seal here with those casting flaws like that. And I see the name Westbury on the dwg. so that explains some things. |

VT...The casting is aly minyum ,, the top square is 3"1/4 x 3"1/4 and the deck like part of it is 4"1/2 x 4"3/4,roughly,,, I have'nt done anything to this part except use a piece of wire to get all the sand out from the water jacket cavity.. I don't know for sure but the bottom looks like it may have been filled in at the really shiny part,, then ground off flat,ish again... I really like the sound of that idea about the flange and gasket...at least I might be able to progress a little again if i go that route ...because the deck part has to have 3/16ths taken off of it but even with that extra bit of room for threading, I don't think i could do it... I better stop posting photos or the mods will shoot the boots off me... :wack: ..thanks for the good ideas... ...mike.. |

If thats the ET Westbury engine. I as already mentioned used a flange ad bolted it up with an O ring groove in the flange. Check out the drawings I seem to remember a far amount of dead space and the hot end was specified copper :Doh: Good luck she will be a great runner. cheers frazer |
