WORK CARRIES ON ON THE BANTAM WITH THE CRANK PRESSED TOGETHER AND TRUED UP, NEW BRONZE BEARINGS FOR THE GEARBOX TURNED UP AND WORK ON THE REAR WHEEL, ALONG WITH A LOOK AT THE NORTON STAND AT GOODWOOD.
It always surprises me that the straightened crankshaft doesn't get knocked out of true with all the engine movement, torque and vibration! Good to see how it's done!
Had a new big end fitted in my C15 by a well known company near Derby. My mechanic is new he told me and had some trouble getting things lined up. It looked like it had been thrown off the top of Blackpool tower when he handed it over. It must be great to be a competent machinist with your own workshop. Thanks for your excellent video entertainment.
My pleasure Steve, glad you enjoyed it and sorry to hear of your experience of poor workmanship on your crank, that's why I try and do as much as myself as I can.
I have a confession... When I see a man with your abilities, talent, and technical know-how reduced to beating the death out of something on the shed floor... I get a little too much joy out of it.. Sorry. (FYI.. Employees always say they've learned their lesson but it's best to keep them walled in for an extra day or two, just to be sure.) Cheers
@@TweedsGarage Unfortunately that's me and I am off sick at the moment so I can't go get more! Your film has inspired me though to work out what I need for my Velocette and look at doing an order from the UK spares. I was hoping not to have to touch the big ends but I definitely have play there I should address. Plus I need new barrels, pistons, heads, etc, etc, etc.
Good one Allan! I see the hydraulic press is being put to good use, I think a club hammer and copper drift would have been used back in the 60s, so much nicer when you can get a controlled press fit, and using the back stop spacer makes it even better, that jump when you overcome the interference makes it difficult to end up where you want to be. Stay safe! Chris B.
Absolutely Chris, the hydraulic press is becoming an indispensable piece of kit in the Garage, used it on the Riley bodywork which will be seen in a future video. All the Best.
That's the thing about really good press fits - they are not gentle, fragile things. They take a LOT of persuading to move. But - at least once trued in you know they will stay there. Worth the effort to get there for sure. Frustrating and satisfying all at once. Cheers!
Welcome to Bantam crank world, you are right to point out the differences between modern two stroke cranks. I thought you did really well, you shouldn't have any issues with the readings you achieved. Thanks for the mention, Old Chap. Best wishes, Dean.
Nice to see a bit of lathe work. Yours is nice and quiet too. Do the grooves in the bushings act as oil supply? It's a bit minimal isn't it. Think I would dremel in a little oil catch scoop into the upper surface to encourage oil down into the Bush.
Hi Chris, the gears sit in oil and there's plenty thrown around the gearbox ( to the point that it travels up drillings to lubricate the main crank bearings ), the groove on the outside face of the bearing faces upwards so oil runs down and around the shaft. They are probably there for when everything was new and a bit tight. Glad you enjoy the lathe work, there's normally a bit on most of my videos
What, apart from causing trouble, is Jenkins studying? That hydraulic press you bought has been very useful, not sure how it could be done without it. Thanks for the video.
Apparently he's studying the form...i don't think it's the horses, more likely Beryl Brown at number 42. The press keeps on giving as it was used for bodywork forming on the Riley ( to be seen in a future feature ).
Yea nice work not that I’m a expert can’t wait to see the side case repair in full close up detail 👍🏻👍🏻 bit of alley welding, maybe some milling surface grinding Oo sorry I gotta stop I’ve come over all unnecessary
Allan I think it's only fair to make you aware that Jenkins was up the bounty Tuesday again this time he was singing ubsean sea shanty sI think a reduction in pocket money might be in order pc bob Goddard
Thank you PC Goddard for bringing Jenkins outlandish behaviour at the Bounty , words will be said and Sherbet Fountain allowance will be slashed. Its good to know the snug in The Bounty is on your beat 😉
Having seen the work involved in truing up the Bantam flywheels and crank, I worry that when the crank is assembled in the cases, will the apertures for the main shafts be in line as well or so worn that you could have a problem with bearings, etc.
The old bearings inner races and crank shafts bearing surfaces took all of the damage, the outer bearing races hadn't spun in the cases and they are unscathed in that area...........damaged in plenty of others though 🙄
