Afternoon Guys

Jacques sorry to ask questions on a weekend.

Is there some dims ( dimensions ) missing or am I being DIM which is more likely

Cheers

In case Jacques is off sailing, those dimensions can be determined by swinging arcs on the substrates or a lofting board if you wish to piece them.

Or, if you take the tan^-1 of 184/770, it would give you an angle you can use to get the dim.

I do not know how to get the other locations, or that I would use the number. I'm a bit confused why one side would be different than the other as well. If it were me, I'd use a batten instead to determine a line that looks right to me for the bottom arc.

I'll work the other dim here in a minute.

Oops. I made a mistake in the post, but I caught it immediately.

For the upper left dimension...

Given 770 and 184, a right triangle, the inv tan of 184/770 is 13.44 degrees.

Given a 90 degree corner of the windshield frame, the remainder angle is 76.56 to make the line from 770 up

The tangent of 76.56 is 4.1856.

527/4.1856

The upper piece on the left is 125.9mm. Verify with other method(swing arcs). Lower right is then ez to back into. 770+125.9-710

Again, on the lower, I'd batten that as I don't understand why they vary, but I also don't understand the 11mm variance either.

I think you are in the art a bit here. Help at all?

Jacques?

Quoted so he'll get notified to answer the above questions on dimensions.

I'll try to remember that method. Thanks.

Hello

Dan, Apologise for the slow response.... we have had family over and it is too HOT.

Jacques seems to be out on the big blue sea ( lucky bugger )

I repeatedly look at the drawing and to me something does not stack up.

If you take the central windshield the outside measurement is different from the meeting frame outside measurement. Call me old school BUT if both start from the same point as per the drawing surely the frame meets at the same point at the top so it must be the same dimension..... Am I missing something.

Jacques I am being picky here ( pain in the back side ) I will fit the wings and work the rest out by measurement ( I just like to check once built that it meets your drawing ) To date your drawings spot on... Apple for the teacher

Would just like to know i am doing it right....

Cheers

You can calculate and it will be correct but that was not my intention. Once you get to the cabin and pilothouse, it is very important to work from dimensions taken from the assembled parts. The dimensions I give for the windshield are to be used as reference points and to estimate materials. For the windshield, first build the roof top and the wings. Set up a couple of references battens and take final dimensions from there.

I will give the dimensions you ask for but need 24 hours. I am not sailing this time but I am on vacation in the mountains. I will stop somewhere and redraw that windshield quietly tomorrow.

It is important at this point in the build Les that you understand that boat building is art.

The things you make from here out will largely be of your design.

My helm station, for example, I am a bit disappointed in. I spent many hours on it, but I wish the displays were more horizontal and the wheel higher.

I have a bench that is too high and too narrow; despite spending a lot of time thinking it was great..

The windshield, I recommend, you treat as an early foray into how do I wish to build it.

Some examples of alternative ideas...

1. Venting the lights by buying a custom made venting unit.
2. Venting by adding a small port vent in the window.
3. Adding high density foam in order to manage a trim ring install.
4. Using battens and cardboard to determine what you like.

Be prepared to ask for advice about bench heights, wheel heights and other things as you move forward. Electrical systems are also artsy; despite rules around them. A solar panel or two on top of the cabin, or foredeck, for example. Autopit, for another.

It can be fun.

The autopilit option on Aspencats is $6600, fyi..

All the best. The build is really lovely.

I spent a lot of time templating the front windows and windshield for Redfin. No drawings from woods. Those came out really nice. Windshield supposed to match front window angle....we'll see..

All template work, windshiekd is aluminum

Wheel too low
