Ello lads ____ just an idea from the Colonies...... But.. One thing I have used for turnbuckles / gauge bezels and the such area an easily found item called "Bugle Beads" found in most craft & beading stores.
Available in many colors (inl.'g metallics / gloss & matt) in a variety of sizes.
Might try these sometime. They are time saving, strong, and versatile.
Well my good chaps I'm off to get my knickers in a bunch over a different issue. Tally-ho.
