Does anyone have any tips on how to remove the old, badly chipped badge so that I can insert a shiny new one? Digging it out is likely to damage the timing cover, so defeating the object of making it look nice!
One way is to drill through and knock it out from the inside, but that seems a bit drastic. I could seal the hole afterwards with Araldite or similar, which is what I might use to glue the new badge in. I will probably try drilling into the badge using my pillar drill to control the depth, but my first brief attempt using a hand drill showed the enamel to be pretty hard.
Never done it,but assume…

Battered Badges
I do believe that the round badges were originally glued in place. I think that Lionel is going to have to get violent!!!

Whatever glue you use needs to be ok with heat. Some of the 2 pack epoxy fillers are used for porting work so should be OK.

Core plug
Yep, done a few of those over the years but you 'sealed' the core plug by tapping it with a hammers which spread it out against the housing. Just a smear of soft sealant if worried as the plug must not be too tight - it's a safety valve after all. I will try a slim drill in the front to start with, just to gauge the depth to the alloy. Failing that a drill through from the inside to suit a slim parallel pin punch.

Hi Lionel, The enamel badge…
Hi Lionel,
The enamel badge is exactly the shape of a core plug before it is hammered. I needed to change mine and luckily had a spare cover to practice on.
I drilled a small hole in the centre after tapping it gently to remove the enamel, it is only about .015" thick and made from brass. I then screwed in a self tapping screw which 'jacked' it out easily.
I hadn't realized that double sided tape was around in 1956 but that is what it was held in with. I bought the bike in 1962 so assume that it was the original badge.
Regards,
Dick

I use silicone glues for badges that might need to be replaced in the future. Just a thought. 'Superglue' market a convenient one in small tubes.

Never done it,but assume that its a bit like a core plug in a watercooled engine , We used to punch a hole and lever out The new one was tapped to spread it ,not so easy with enamel finish.
