Bryan's GT-Forte build

I purchased a Gt forte laser flat pack at the end of 2017. after looking over what i recieved and the instructions Darrin George sent me i began the journey to build my GT-40. I've decided to start a thread here to gather as much help and advice as i can. my first role of buisness to do was create a good table to build on. i designed my table to not only construct my gt-40 on butt also to build a airplane i have plans for in the future some time after my 40 is complete.

Hi Bryan. That takes me back a few years. I think it was the most enjoyable part of the build to date. ;-) Keep the pics coming.
 
Thanks nick , I bet it does. Im actually working on the middle section now. Im following your build in the order of how you assembled the sections together. Although i weld out the entire frame each time i add to it and grind the bottom flush each time. So far its staying pretty flat.
just takin it slow.​
 
Looks good Bryan.

What did you use for your table top? Is that laminate countertop? How's it working for you?

I bought the same chassis kit early this year but I haven't started the build yet. The build table is the first order of business and I haven't decided what to do yet. Mine is most likely going to be a one-time use so I didn't want to get too elaborate with it but at the same time, I want the chassis to come out flat.

Thanks for posting, please keep the updates coming.

Hey charlie i used 2x6 for the frame with 2x12 at one end which is actually the middle of the table. Below the table is storage and im using 3/8 ply there. The top is two layers 1 layer of MDF 4x8 and then melamine 4x8 both are 3/4 inch thick if i remember right. If i did it over i would just use 3/4 inch plywood. Theres a spot where the 8 foot sheet ends and a 4 foot section begins, that has a slight low spot. I will eventually fix that butt i just build on the 8 foot section when fitting up. This tables overall length will be 24 foot for a wing i will build one day. And the L shape is cause i didnt want to cut these sheets so i can use them for the second table later down the road. After the chassis is done i will dissasemble the table and move it back to my other shop , 2hrs away. R u n the USA? And did your kit come complete? If your looking for a cheap solution i would buy 3/4 ply finished on both sides. And clamp angle iron under it to keep it flat . And just check it with a straight edge.
 
Hi Bryan,

Thanks for the info.

Yes, I'm in the US in southeastern MA. No, the kit didn't come complete, I'm missing several parts which I'm still trying to get.

I welded up the middle rail section some time back in january. Then i had to take a break from the build to remodel the house. Hopefully i will get back to working on the 40 over the summer. No other real progress at this time. I did buy a Tig for Christmas butt its still in the bag havent even pluged it in yet to see if its going to work. Gota get back to building. Will post new pics as soon as i make somemore progress

Made a mistake or two and had to cut and reposition a few of the tubes. Guess thats what i get for getting in a hurry. I mocked up the middle section and most of the vertical tubes that attach the two together. Everything jiged up good so hopefully this weekend i will be able to do some welding. Ive been searching for a source for 40mm sq tube. Its hard to find and expensive when i do find it. If you know of a good fairly priced source do let me know. I will eventually have to bite the bullit and order it so i can move on. I also am wondering what others are using for round tubing when fabricating A Arms and rear links. I was thinking 1.125 Dom with a .125 sidewall thickness. Or 1" chromoly with .083 wall. Let me know what some of you are using. And if someone has the full dimensions for the rear upright pm me i have a partial drawing of it and need a little more info.
 
Looking good there Bryan. Takes me back to 2014 when I was going through exactly the same process. Made a few mistakes here and there but its relatively easy to remedy. You shouldn't have too many issues getting the whole chassis complete from where you are now.

Planning a massive weekend on my build as I need ti get her finished by xmas allowing me time to get the paint etc. complete before were off to the LeMans classic next July.

Nick.
