Time for another, orphan rebuild session! This, distressed non runner. A Seig HAE 03/ Grizzly H8104, arrived last September......... I pulled it out of the orphanage a couple of days ago. Couldn't think what to call it. A pal suggested Metisse. As it will be a bit of a mongrel, by the time it's done. I thought, that will fit nicely! :thumbup: Apologies to any bike men out there who were hoping for a different project. I don't think the Rickman Brothers should be too concerned! It's been mangled together, by a bad tempered gorilla. Nothing is in line/ square. Even the factory installed displacer bush is leaning! The cooling fins had been jammed on at half mast. Then someone has tried to "unscrew" them. Breaking the swaged joint...... A few days soaking in WD40, allowed the ring to be pulled off. Giving access to the displacer, cylinder flange screws. The square flange would spin, like a ball bearing....... M5 screw, to drive the flange. Plus a digging in tool......... Came apart nicely........ Silver soldered........ Wicked through, nicely....... A 3 thou' flick across the face. Near enough........ That's the first bit, straight and square....... Shouldn't take too much to sort..... Mebbe! David D |

Pressed out the lop sided displacer bearing....... Made another, with a couple of thou' hole clearance and larger, 12mm dia base. Held in with sleevelock, it should stand square....... Also a new shaft, as the bent original had also been chewed with pliers. :palm: The main bearings had been hammered in........ So, I drilled 'em out. Then opened out the holes to take 9mm o/d ball races....... Didn't have a 9mm reamer. So, I triple drilled to size. Finally, using my 9mm "brass" drill. The bearings are a beautiful sliding fit! Two, in each frame. Got to tackle the crank, next........ Thanks for watching........ David D |

A very lucky hot air engine to have fallen into your hands! I will be enjoying this one. :beer: :clap: |

Jim. VT. That's much appreciated......... Thank you! :thumbup: During a quick look at the crank assembly, I thought they had used a roll pin, for the crankpin! Then I realised, the crack, (inclusion?), continued along the shaft too! :bugeye: With the lop sided big end eye. (See last pic). We need a full rebuild....... Tried to use the original throws. But couldn't get them into alignment........ Made a pair of new ones......... I don't do filing too successfully. Prefer to mill, where possible. This is the set up for the r/t. M4 caphead and nuts, plus 4mm silver steel shaft......... Grip on the nuts. Drive via the shaft........ Swap around for t'other end......... Loctite plus pin, for 3 of the joints. And one, M2 grubscrew to allow dismantling........ Opened the 'orrible big end eye to 5mm dia......... Made up a flanged bush, and matching washer......... A spot or two of loctite, and it went together nicely, ready for reaming......... Looks ok, I think......... Wonder if I should have made balanced throws? We'll see! All ready now. For clean up, lick of paint, and rebuild, next week....... Thanks for watching! :thumbup: David D |
