There are some multiple steps but costs very little and can be done without breaking the bank too. I did a walkthrough bassboat style wiindshield and needed to obtain some form of structual intergrity at the centerline when in open seaway and when open for anyone going for and aft. I hope this is not to rambling here.
I first built the windshield in one piece planning for a centerline cut in the center styles after I finished all the parts including making the mortises in solid an seperate woods. You need to do tis so all the parts will line up better than just doing this in three pieces. I was able to achieve this also out of one piece of wood, 8/4 resawn making the winshield bookmatched woods too.

I first installed plywood pieces mortised to the double console mouldings. I did this because the pieces would need to be more stable than what small pieces of wood and grain issues would have been to also grab onto and the stress related issues.

I then riped mahogany to less than a quarter inch and glued up to the sides. he pieces also overlayed the mouldings for further structual integrity.

I sanded both faces smoothe.

I then figured out my shape for built in handrails and cut to shape.


I then glued up a face veneer, ripped also to about 3/16".

I then sanded the face and ended up with an fairly nice structure and not to heavy looking, pleasing to my eye and have not broke the bank doing so.

I will now clean up the inside cutout and run a small piece of thin glass around the edge grains to seal it up and paint out a dark brown color. YOu will need to seal the faces with duct tape to keep clean of any resins too. [/img]
Also for increasing the stresses over the long haul I installed corner gussetts to further strengthen the free standing sides which will help in case someone is pushed or shoved against it. The solid framework also were built with dovetails which keeps wood joints from working further too.

I also fabricated the opening joint on an angle so an issue with jamming down the road will be minimized too, or so is my opinon.

Enjoy, and hopefully these shots will help someone and may not be too off topic here. If there are any other questions in the way that the initial windshield was created, feel free to ask. I have the steps in a photo journal.
