What have you done with your bike/s today?

So... Macbeth... what does that actually mean?

My camera fell off my bike

G'day Mac.
And it filmed it's own escape

But has it forgiven you yet?

 Found that bargain inner primary chaincase (S/A) has a nice big twist where someone had neglected the spacer to the frame. Lug also broken off, which explains it all. Anyone experienced with bending alloy die castings preferably with a barbecue, 4 lengths of lumber and 4 G Clamps? Cost me peanuts, so no big loss but annoying all the same.

What spacer?

Bloody hell another bit I Got wrong on my GF project

Still I am working on it at the moment and I looked this up on the forum and can use washers, or maybe some SSteel tube.

Just another job!

Thanks for this comment they do help me.

I rode my modern BSA to the nearest dealership yesterday for its 3k service. My local place have closed their shop so I had to ride 40 miles to Stourport-on-Severn. We've had almost constant rain this spring but yesterday was beautifully sunny albeit chilly;  I needed to put my silk undergloves on. There's a 5 mile section of dual carriagway on the route so I was able to give the bike some beans. I love my new Gold Star!

Swarfy, I know the gap is usually about 1-2 mm, so that is the aim when bending it back. I pack with a few thin washers after tightening up the front 3 screws until they stay there before putting the bolt through. I found my inner bent the same, as someone had put the inner on the outside of the frame instead of the inside (me many years ago when I had no brains or experience ). I laid the inner down (exterior down) cold on a flat bit of 3/4 inch chipboard and whacked it in appropriate places with a large rubber mallet. mostly at the rear of the sprocket/cush hole. I was amazed how it bent back to shape with no cracks. I assume a bit of heat would help.

 Col... There must be a good few out there, all bitter and twisted, just like their owners who struggle to seal that Primary Case. I won't say BSA frames were made with today's laser precision and after all this time engine mounts, frames and crankcases can all have a degree of flexibility when it come to final assembly. This inner case is one area where a small difference at the front makes a big difference at the back and you can bet the average Joe, when faced with that gap between frame and case simply bolted it on nice and tight...under tension and ready to let go.

 Any component installed with any element of strain is a top candidate for structural failure, hence broken mudguard stays, headlamp brackets etc. Always make the parts fit without strain and save hassle later.

 I'll warm it up and see if it will flex back with a bit of a tweak before wasting time on the lug repair. Good to know a few smacks can do it when I lose my rag after being too gentle.

 Cheers.

Sealing that bloody primary case

[Joolstacho]

Swarfy is pretty right here IMHO. When I built mine (many years ago!) I could see that the PCC would be slightly distorted if I just bolted it up at that rear mount, so I shimmed behind that rear bolt to eliminate distortion. (Not that I'm any fabulous engineer,) but my PCC has never leaked.

worty happiness is a sheet of cork 1 to 2mm thick and hey presto no leaky. i made one for betsy and this is for the berger build , treat it like an old car pressed tin valve gear cover gasket and all is good.

Aha, nice one Bergs!  Going shopping for cork sheet right now.  I did find a nitrile one for the timing side, not fitted yet as a standard gasket works well, but going for a thicker medium looks like a very good idea (providing it's not on a face where small clearances are important)!  Any tips in cutting it out??

[berger]

any tips on cutting it out ? yes don't use blunt scissors . apart from that if you haven't got hole punches fasten your outer case down with clamps solidly  to the sheet on a flat board and make sure it is not going to move, then use a 5mm drill to put the holes in and a 7mm for the 3 5/16ths holes, draw round the case and cut out . be careful cutting the inner out.. when fitting be gentle on the screws and leave for a day then you will find they will nip up a bit more , don't over tighten and split it. ps make sure when drilling the holes it is clamped tighter than your wallet
