et>Both the UK design (and Dan H.'s implementation, each featuring large turnbuckles or threaded mounts) and Santiago's design (with boltable straps) allow the builder to weld only part, if any, of the pieces, and otherwise slip in components under the plywood and cowling pieces, and around the instruments, then assemble in place.This can be an advantage.- If you weld and bolt up the harness assy. first, and then build all the rest, you can make it all one piece as welded.- But then the harness assy. a) is either in in your way as you run tubing, wires, cables, and mount instruments, put the ply pieces up, etc., or b) requires you to keep putting the mount in an out to see if things clear, and to get it out of the way.I am not saying this as artfully as I might, but perhaps you get what I mean.Tim in central TX-----Original Message----->From: Bill Church >Sent: Jun 10, 2009 2:38 PM>To: pietenpol-list(at)matronics.com>Subject: RE: Pietenpol-List: front seat shoulder harness attach>>>I've seen photos and drawings of the UK design (see>http://www.westcoastpiet.com/seatbelts.htm ), and I have not been able>to come up with a reasonable explanation as to why they need to have>those turnbuckle-type fittings in there.

Bill & Santiago, The UK design takes the cross brace cables off the top of the shoulder harnessattach, the turnbuckle-type fittings are how they adjust the cross brace cables.I made mine almost the same as Ben. After seeing Santiago's design, I wish I haddone it that way, very cool Santiago.Skip----- Original Message -----

REAL Wacos don't have shoulder harnesses. Stearman shoulder harnesses do not attach to the welded steel fuselage, the aluminum (or wood) seat is the attach point for the shoulder harness. The same thing for later Wacos. Because some Stearmans had wooden seats, you are back at square one.Gene ----- Original Message -----

>>>Both the UK design (and Dan H.'s implementation, each featuring large turnbucklesor threaded mounts) and Santiago's design (with boltable straps) allow thebuilder to weld only part, if any, of the pieces, and otherwise slip in componentsunder the plywood and cowling pieces, and around the instruments, then assemblein place. This can be an advantage. If you weld and bolt up the harnessassy. first, and then build all the rest, you can make it all one piece aswelded. But then the harness assy. a) is either in in your way as you run tubing,wires, cables, and mount instruments, put the ply pieces up, etc., or b) requiresyou to keep putting the mount in an out to see if things clear, and toget it out of the way. I am not saying this as artfully as I might, but perhapsyou get what I mean.// Tim in central TX>>-----Original Message----->>From: Bill Church >>Sent: Jun 10, 2009 2:38 PM>>To: pietenpol-list(at)matronics.com>>Subject: RE: Pietenpol-List: front seat shoulder harness attach>>>>>>I've seen photos and drawings of the UK design (see http://www.westcoastpiet.com/seatbelts.htm ), and I have not been able>>to come up with a reasonable explanation as to why they need to have those turnbuckle-typefittings in there.
