John,



You are correct, dentist don't mix their own composite except for bonding 

porcelain to tooth structure, but then again most of the time the assistant 

does the mix. We do however use flowables in tight spots and corners(low 

filled resin) and higher density stuff in the other areas.  Having worked on 

both the micro scale(Dental) and the macro scale, molds and planes, I did 

have to learn composite basics and in both fields and the techniques are 

interchangable.  If one is a dentist and argues this point, I would have to 

say they are not a very good dentist or they just don't do composite 

dentistry.



Hopefully being a good dentist will keep my airplane from breaking apart and 

make it fly straight with as little power as posible.



For resume' see



http://johngonzalezdds.com/sculpting/sculpting.html   look at full molded 

fiberglass models, big models! Yah the're models, but I am pretty proud of 

them.



Knowing what I know I witnessed the most rediculous demonstration of builder 

assist at Lancair on their intro video they send out.



At the assist center they are laminating in the main wing spar to the wing 

skin, basically closing up the wing and they show a man walking over the top 

of the wing to push the skin down onto the spar thus pushing down on the 

epoxy between the two structures.  Now knowing what I know, both from 

dentistry and building models, once the weight is removed(the man walking 

away) the epoxy mix under the weight would have squezzed out from the gap 

and will not get sucked back under the skin to fill back in the gap between 

skin and spar, there is flex in the skin under that tremendoud weight where 

the man was standing.  Correct application would be to put the load on the 

entire length of the wing skin at nearly the same time and leave it there 

throughout cure.



It may seem anal, but this is about as important as it gets in my mind.

Not to interrupt the primer/filler discussion but I'd like to ask if 

everyone/anyone is using the longeron attach points for the rear seat 

shoulder harness or mounting to a hard point on the cabin top?  BTW: 

Dentists have'nt mixed composite for years,  Comes ready to use, sans air 

bubbles that were introduced by the mixing process.  The curing reaction is 

initiated by light.  Something to do with peroxide, free radicals etc. etc. 

  Thought you might like to know.

John,

     Thanks for your reply regarding composites.  Truly beautiful work 

displayed on your website.  Now to the original question.  Are you going to 

use the longeron attach or the cabin cover for rear seat shoulder harness?

John,  I also used the longerons.  I don't know if I've seen

anyone else use the cabin top for the rear seats.  You'd need

to add hard mounts of some sort.

David's AMSAFE inertial belts use a cabin top mount for the attachment.

I already made a bunch of changes expecting to use his.

I've placed the anchors on the longerons simply because that is what they 

told us to do.  Also, I think this is a better location because in a forward 

inpact crash, the body will be thrown forward and the belts will be the in 

the truest opposite direction coming from the longerons.



Thanks for the comments on the web site.  I am no where near working on the 

cabin top so unless someone knows it chemical makeup, I will ask Van's 

later.

Happily maried with child and I did build much of this house myself.  I am a 

frustrated Dentist!!!!! The mouth is just too confining.
