- I wasn't happy with the level of vibration from the D7, so I pulled the engine apart and changed the Crankshaft Mag Side Spindle.

Hi again Dean. Tonight i have just done the littlle hit & miss crank again. My mate has lent me his knife edge crank balancer. A lovely piece of kit .All cast iron with tapered blades that sit on the crank. Very old british made. I have done a video which i will include in part 23 of the series. I after a lot of copper tapping got the run out down to 0.7 of a thou. After that i gave up as every time i tried to get better it got worse.

Another fantastic film. It was incredible to see Bones and hear his voice coming from your workshop. Almost surreal! Vindication on stripping and rebuilding the crank. Maybe the stand could be beefed up a bit. Looks like those stanchions might flex to some degree. You were absolutely right. You and Bones ARE the Bantam men. You are both methodical and meticulous practitioners. Between you the Northern and Southern hemispheres are sewn up as far as Bantam restoration is concerned. Everyone else is just playing at it.
Thanks Carl. I think the stand needs a bit of improvement, but it did the job. It certainly was strange when Bones walked out of the railway station in the village! I thoroughly enjoyed his company.
Best wishes, Dean.
@@retromechanicalengineer It shows. I wish I could have met him too.
Many thanks, Dean. Nicely done. Meticulous as usual. I enjoy watching you work.
Cheers, Peter.

Thanks Peter. Hopefully it won't rattle my fillings quite as much. Best wishes, Dean.
Hi mate, back from India and I survived......Just! More tales for our next catch up. Great work again mate. .002" runout will be fine. Can't believe it's only a few weeks ago I was there. Can't wait for the engine to get back together.
Hello mate, glad you are back safely. It was great having you here and I'm looking forward to a catch up.
Best wishes, Dean.
Great to see Bones there and good update.
Thanks Ade
So I am not the only one that has camera catastrophes! After breaking my Kodak twice I started using an Akaso action camera, so far so good, only drawback is some extra processing when editing to reduce the 'fisheye'.
Like the crank balancing tool, has gone on the wish list.
I'm a bit of an oaf, truth be told! It was only a matter of time! Thanks for watching Ian.
Best wishes, Dean.
I hope it works out ok. I have the same press as you. I used old perspex car No plate bits to pack the side cheeks to stop the lateral play & it worked a treat & for nowt.
Steve.
Cheers Steve, it definitely needs something.
a great video Dean and nice to see Bones in the UK I hope you didnt spend too much mate ' on a side note i'm having a sabbatical with mine as I'm being tested for cancer I dont think it is but what do I know but finger crossed I will be back to it soon
Good luck Alan, hoping it all goes well for you mate and you are soon back in the workshop. It was great to have Bones over here, top bloke. We did sink a few and the weather was perfect for sitting outside.
Best wishes, Dean.
A cool stand. I would change the Baring’s.
That's the plan Cain. As little surface area as possible.
Thanks for watching my friend.
Great video, do you do a paid service for other BSA D7 owners, I am just at this stage of my engine rebuild and after seeing this I don't feel qualified to do it.
Hello Adam, send me an email (address should be in description) and we can have a chat. Best wishes, Dean.
Hi Dean,
I've just bought one of the Tag-Z stands, what size bearing did you replace the originals with?
Regards Paul
@@paulfloyd228 I'll have a look later. I had to machine up a spacer to interpose between the bearing and stand, and replaced the screws. I've actually gone back to setting Bantam cranks on Vee Blocks. I need to do something to make my stand a bit less wiggly.
@@paulfloyd228 I ended up with flanged 6202 bearings with bespoke spacers and washers to secure them. I bought button head screws for extra clearance.
@@retromechanicalengineer Thank you! I'll get some ordered, my plan is to make up some "top hat" spacers with a small tapered land at the lip and a recess for a capscrew.
Regards Paul
@@paulfloyd228 you're welcome Paul, sounds like a plan. Be cautious of the fit of the sliding parts of the frame, they can twist when you tighten the pinch bolts and throw your crank reading out.
Best wishes, Dean.
