Very nice. I presume alignment is on the top portion with the knife edges, and the balancing done below on the 2 pairs of brgs? Many years ago, we did static balancing on our knife edges too. Bob R - lovely work on the pre unit single. The bearings are mainly for aligning the pressed up crankshaft similar to a Alpha-Tru aligner the straight edges for balancing. |

This is probably becoming a lost art as Japanese bikes seem to last forever (I will now go and wash my mouth out) Mine didn’t. It cost me £26.10s for a new crank for my Honda twin, back in 1969! Hate to think how much they are these days! It was likely the gearbox failure that precipitated the crank failure at ~21k miles, but the rod bearings were already at, or outsde, the service limits laid down (4mm rock at the small end?). No gaskets needed between the top and bottom crankcase/gearbox halves, mind - and no leaks afterwards. |

This is probably becoming a lost art as Japanese bikes seem to last forever (I will now go and wash my mouth out) Have seen video of one repairer having a stout upright fixed steel bar with probably a lead block on top just banging the offset flywheel on it a recommended way in some books. |

![]() 701 forum posts 203 photos | It was PEEMS first club meeting of 2019 and what a treat for speed enthusiast members. This small club was packed with members and guests many from the speed scene for my friend Graham Sykes Steam Rocket Bike talk. Grahams Wife has a wealth of knowledge on this creation and was also involved in making the pressure vessel insulation blanket apart from other things. Amongst the guest were previous talker Becci Ellis fastest women and others that have done fantastic speeds at Elvington, Pendine and other venues including the TT. PEEMS has such a variation of interests that was the main reason why I joined years ago.

240 forum posts 2 photos | I've been well north of 200mph on my home built bike without really worrying about it but the thought of swinging a leg over that monster scares the hell out of me. Fair play to the guy who rides it. Edited By Pete Rimmer on 07/02/2019 09:34:39 |

![]() 701 forum posts 203 photos | Graham showed other steam rocket machines that others have drove a scooter was fascinating that pressurised the pressure vessel over a barbecue the machine was so hot the rider had to stand up still it did 146mph. Evel Spirit was another similar to Evel Knievel unsuccessful steam rocket but this one was successful.
