| Tina :- Engine and Boiler Build |

Is there more than just a passing resemblance between Tina and the "Suum Cuique" engine by Stan Bray, the construction of which was shown in "The Best of Model Engineer Vol 1" which I bought from the local newsagent 18 months ago? Andy |

Andy - good point. Insofar as the BASIC DESIGN goes (not the scrap/surplus materials/methodology) - I think there is a lot of similarity between the two - although the Latin one is very much smaller than Tina. Presumably this was deliberate so it could be built using the smallest of lathes. Interestingly - cyl. bore/stroke/flywheel dia. etc. are all just about exactly 1/2 Tina sized - ?coincidence? Tina does have the advantage of an eccentric driven pump. As someone said - "I suppose there are only so many ways to design a mouse trap"? Peter |

loco Peter :offtopic: thanks for the write up look forward to you further instalments my problems started when GLR did not supply any documentation with my kit , they then supplied a set of drawings that show the bushes in brass with some shown with the wrong threads to match the top connectors. nor do they state the SWP or test test Pressure ? (which I believe is illegal for a pressure vessel ) I did not get any documentation ( reprint form Stan Bray ) In my kit was supplied 18 1/8 x 1 inch copper rivets that is what lead me to calculate the stress on the fire box wall in a fully annealed state and concluded that it could yield at a TP of 160 for a 80 psi SWP during the interim period I noted that the WP on there site had dropped to 40 psi These are my opinions and are based on my findings and the kit that I was supplied with, which still has note been completed my last build was for "doris" but the boiler for my class 4 tank 5 inch G was farmed out to big for me to handle from a wheel chair :) Stuart |

Hi Peter I bought the kit with the flanged plates, but i am building a larger boiler and have used MDF formers to flange the plates (end plates are in 2.5mm copper) they last long enough to shape the copper providing you keep annealing the copper. I have been working on the boiler for a 18 months on and off, i don't have any photos of the work. I just need to drill the holes in the barrel and form the foundation ring. I will try and put some photos on my thread, i and hoping to get back on the build after taking time out to get married. The fly wheel is looking good, Tina is a nice engine but i have enough projects........ William |

Thanks William - very best wishes for your wedding. Peter |
