sb5 and sb6
 

can someone please explain why sb5 and sb6 have compound angles? Can they be cut so they lay square against the seat back bracing?

thanks

THe compound angles on SB5 & 6 are due to the angle of the seatback top rail SB2.

It is not too easy to visualise looking at the drawing & becomes a lot clearer once you start constructing the seatback area.

Andy could probably explain it a bit better than me :)

ahh, just me being stupid, i was thinking that the two horizontal rails were paralell. Guess il have to cut them as the book intended. I HATE COMPOUND MITRE CUTS!!!!!!!!!:mad:

Unfortunately the top rail is paralel to the bottom chassis rail & the centre rail follows the angle of the seat back :)

SB5 & 6 are tricky little devils to cut .... Well they are if you are a senile old twit like me :o :D :D

No sympathy on here Ronnie,just good advice.

Senility ? no way mate.:D

You wouldn't say that if you saw me spending almost 2 days sitting on a stool, looking at a big box of bent pipes, thinking " How the hell am I going to make a manifold out of that " :o :D :D

Ahh SB5 & SB6

They are tricky little blighters indeed.

When cutting them, from the book diagram, ignore the sketch showing a 17degree angle.......this is the angle you create when cutting the compound angle.

hope this helps

cheers
