sorry to jump on Tatey,s thread.
Sean,
i did realise you meant the wishbone jig block but couldn,t resist the chance of a "plug"
in fact my current price of a flat pack kit is lower than armoto,s was
i think i,m starting to be a sad git as i,m now able to tell each tube its part code & dimensions almost without needing the book, Tall Andy & even Chris Gibbs told me i need to get out more.....lol
hmmmm ..... the flat pack for the single seater will become available once the book is published,

,
cheers
andy
