Title: Tank badges
Post by: Tomcat on 26.02. 2025 21:12
What is the correct way of fitting the badges to the brackets securely without damaging the badges?

Two screws and nuts in each badge to hold the clip which just slides into the bracket in the tank.

Andrew, you make it sound so simple!  However, I remember chipping the edge of a new badge when trying to do exactly as you describe.  Even so I do not know of any clever tricks to avoid this happening other than extreme caution, and possibly a smear of Vaseline (which I thought of too late) to help the badge ‘slip’ into its pocket on the tank.

After fitting the screws and nuts, I usually put a few blobs of Evo-Stik on the nuts to stop them coming undone.

My 2 year old badges have already cracked. Could be cheap after market job or just vibes. I plan to glue some old inner tube to the back hoping to reduce vibration and make sure they do not fall to bits.

I thought the A65 badges were fitted on rubber mounts, I wonder if it would be worth trying these?

When I tightened the screws I've cracked the plastic badges, the nuts are standard type and need to be tight to not vibrate loose.
I've ordered two more badges and plan to glue them to the brackets with silicone then loctite the screws and nuts so they don't need to be tightened.

The pear shaped badges were modified to (hopefully) stop them cracking, see below bulletin from 1965. The rubber pad was added on the C15 and A65 from around 1964/65. I don't know to which form the current repro items are made.

 Thanks Julian I do have counter sunk screws. Not sure who sold them to me but I wish they knew this.

With a little luck I might have this bike sorted by the time I die.

My badges trick is using 3.5mm screws, the ones used to secure electric light switches and mains sockets. the tap is available from screwfix etc comes fitted to a handle. I did buy the "correct" screws when I bought the (4"round) badges but they would clearly soon pull through the perhaps drilled oversize holes.

Another trick might be to put a thin rubber washer or skinny 'o'-ring underneath each screw head between the screw and the plastic. Then tighten the nut on the back without turning the screw. Plus all that has already been suggested re. glue/loctite etc.
