Hi Peter. Thanks. No, it is an outfit so the ‘B’ round cover could be the way to go, except having an ally spacer cut would be a lot cheaper. Might put one on my Birthday/Christmas present list. ?
Re Peter's suggestion:
From the VOC Spares webshop:

'B' CLUTCH COVER POLISHED

Use C28-Gasket when a multi plate clutch is used 'wet'. Back in stock GBP 87.48.

Might be a much quicker, simpler and better solution but then again you may not have spare disposible cash

Hi all. I have been in touch with Paul Holdforth about the Cometic gasket and he sent a photo. I sent him photos of the gaps left when the cover is fitted, and he agreed that his gasket would not do the job. I have decided that the way to go is to have a round ally ring laser cut that will cover the gap. Thank you all for your help and advice. See photos below of the problem. The first is how I cut the gaskets up to now, the second is the gaps left with the cover fitted upside down. The tube over the top is the ‘D’ stand lifting handle.
Just found this problem with my covers & was toying with using HTS rods to build up the lower portion of the Primary Cover, also need to fill two holes that have been drilled in the bottom of the Primary Cover.
Think I`ve got a B Primary on my C twin.
How would you go about getting the Laser Cut plate, & have you got a place you`d recommend ?
Cheers
Dave

It's not hard to cut a ring out of a sheet of alloy by hand, Takes a little time.
I did it on one of my racers, To make room for a multiplate Clutch, Then I cut a bit out to let the air through.
Cheers Bill.

Plenty of places do water jet cutting just supply them a cardboard template at sort out what thickness you want
I got my grey flash plates cut out of 8mm for a few pounds

Thanks Bill,
I may have a go, could bolt it to the Primary Cover after roughing it out, I`d realised after I posted the message that I could use the gasket I`ve got to make a template.
Cheers

Thanks Tim,
I realised after posting that I could use the gasket to make a template so I`ve got a couple of options now thanks to you & Bill.
Cheers

Hi Dave. I searched local laser cutters on Google but they wanted too much money for a one off, so I went with the above and cut one by hand. Not perfect but has done the job well. Thanks to all for the advice.

Don't you always wish that there was a gap in a band saw blade so you could cut holes.:):):)
You could always start with a small cut inwards, Then Solder /weld the gap !!, I didn't have a band saw, I always do it the hard way !. Cheers Bill.

I used an electric jig saw and finished filing by hand. The inner ring was quite easy after drilling four holes fo the saw.

The irony is I`ve got a bloody great Wadkin bandsaw, but it`s a woodworking one,
Like Bill`s idea of plugging the gap though.

Best thing I ever bought was a Buff/Polishing wheel and special soap, To go on my bench grinder,
If you ever make anything in Alloy, Which I do a lot, You can buff it up like new, Or when you take your rocker Caps off, Outer cases, Mudguards etc, I gave a spare one to Ron, When we built a Comet for a friend, I don't think he was keen at first, But after cleaning a few bits up, He is well happy with it. Cheers Bill.

I`ve got a nice Buffer wheel, really does make life easier except when it pulls the stuff out of your hands.
I`ve found that the soap for Stainless Steel works well on ally.
Cheers

water jet cutting companies cascade by the dozen out of the web NOT to be confused with lazer cutting

When I had my Doctor check me for my Race Licence, I told him I had a problem, He said, " What colour is this Blue Book ", I said Blue = Passed !!, Still makes me laugh. Cheers Bill.
