Bullseye window

[Senator]

I have made the circular frame and sash now I need to get the pivots centred up in both parts plus beads/stops.
My question is how and with what type do I draught strip the window. Any ideas advice out there?

My circular window has a groove routed in the rebate in which the draught excluder is fitted - looks like Aquatex a10. It's what was fitted to all our windows and doors and seems to work OK. If you want I'll try and get a photo.

Yes Misterfish a photo would be good IFF poss. The way I see it the outside fixed bead is at the top on the outside and on the inside at the bottom. But the area between the two seems to me the problem?
