Nick. Thank you! Dean. Yes, you're right! But, I love sorting out orphan engines' problems...... The first Derbyshire Mineworker I ever met, told me. When there's a problem...... "Allus blame t'other shift". :thumbup: The buck stops here, on a first build! :scratch: Jack. I've bought some dark green smoothrite, for the engine. Think I will do the skirt in black barbecue paint. That should stand the heat, and hide any lumps & bumps...... Right, then...... This air transfer tube has caused me a lot of thinking time....... Still not happy! :scratch: Can we have a committee meeting? :smart: This is what was originally fitted. Water could leak between tube and casting. (Never minding the termite holes!). ::) Around 3" long. 5/16" o/d. 5.5mm bore. 36tpi threaded through the displacer cylinder wall. 5mm transfer hole. Screwdriver slot in outer end...... The available area/ space, now looks something like this. With the 7mm bore ending within 5thou' of the cylinder wall, I thought sealant on the thread would squirge into the little gap, as the tube is threaded home...... This is my idea for the tube. I have an M7 x 1 tap & die. But the 5.5mm bore might leave things a bit thin......... Anyone got any good/ better ideas? David D |

Hi Dave No good or better idea, except I have M7 x 0.75 mm pitch taps & dies ... might give a microtad or so more wall thickness. Although I don't suppose it's a lot of difference from 1 mm pitch .. welcome to a loan if you require :thumbup: BC |

Cannot deal with anything vaguely resembling recognition or adulation. :bugeye: Don't forget, I spent my life as a Field Techy on IT gear. Dog-hangings and b0ll0ck1ngs by the truck-load, yes. Can cope with them. No procedures in place for owt else ... :lol: .. never been required ..... Mine are new too. Apex UK. So don't know if these work either .. ?? So, .. When and how ?? PM your phone # if you want a natter. As it's for nowt at weekends .. Dave BC |

Well..... With the amount of cast iron dust I'm producing, I should have called this posting. "Getting down n dirty with Mrs Robinson". :D The saga continues. Fitted the skirt and displacer tube together..... Just a little mismatched! :scratch: The crescent, is the end of the displacer tube....... No wonder I couldn't get the hot cap properly centralised! :bang: :bang: Bored the mouth of the skirt concentric to the displacer bore...... That's the new, glued in place, repair section I'm gripping on..... Great stuff, that high temp slidelock Dean! Thank you!. :thumbup: Drilled and started tapping, the 6off, 6BA threads holding the deck casting to the repair section. The (new) plug tap feels very stiff to turn..... :doh: Job stopped. Quality tap ordered, before anything goes snap....... I hate that sickening/sinking feeling! :( David D |
