Hi Shawn,

I am very interested to see how you are going to get that out of the house, when it is finished.

Keep us posted on the progress, looks very good.

The wife would lynch me if I tried to build this in the house... AAARRRGGGG triangles,, 40 down 90 to go ....

[Shawn]

Thats a 2.7 m piece of mdf in the middle,,,you get an idea of the size yes ?

[Shawn]

Lester, your a genius,,,gave me a great Idea...Ill finish it in the den , then punch it up thru the roof, and then extend the den, be easier and cheaper...

Thanx

[h0ughy]

[Shawn]

[Shawn]

:lol:

[Shawn]

And I cut another 60 triangles today, will post a fresh pic with layer 2 on, after that a lot fewer triangles are needed per layer, 1st layer 40 , 2nd Layer 40, third layer 32, 4th 22 and so on.... going batty here :help2:

[Shawn]

2nd Layer of triangles well on the way, any error in the first layer is compounded 5 fold in the second, since its having a big slit in it anyway all errors are focused on the part to be removed. pick the bad spot and cumulate errors there. Second layer is tricky because the support for curing of glue is limited, its coming along ok though, and I will post pics, and maybe even write an article for IIS, once finished...Just in case your intersted..

Have a good time
