New builder, Wing Jig thoughts?

[AlpineAce]

Hi All, I just picked up an unfinished kit. My first step is to do the wings. I'll have to do one at a time as I have a 1 car garage, and short on room at the moment.
I have been reading a bit on the different versions of wing jigs. Id appreciate some feedback on what im thinking.
Id like to use some T-slot material (as I have used this for other fixtures in the past)

My concern is, about alignment: I have seen some mount directly to the floor, which is what im considering, but I doubt any floor is perfectly level, and with something of this length, Im worried it would be hard to tell if something was off from one end to the other.
So where is it critical to get set up right, and where can I adjust afterward? Im guessing the spars will provide some sort of alignment themselves?
is there some kind of laser alignment tool I can use?

I plan to mount to these plates, and the bolt the plates to the ground.


Thanks!

What model? Assuming it’s a prepunched variety, you don’t have to obsess over the jig. All you have to have is something on each end to hold the spar. You will want to prop up the middle of the spar to take any bow out once you get to the point of adding skins, but whether or not the spar sits perfectly level or tilts downhill 2” because of the floor really doesn’t matter. It just needs to be straight with no twist, and quite honestly the skins will correct it if it’s not perfect anyway. My setup was made up of junk 2x4s with a piece of angle bolted on to set the spar onto. Worked fine and my wings came out with zero twist. My floor is far from flat.

You will level the spar so floor doesn't matter.

If you're building a non-pre-punched kit, then you will need a wing jig. Don't worry about leveling the jig. Instead, make the wing support attachments individually adjustable so that the wing itself can be trued.

I found it worth making my jig to support both wings so that I could do similar tasks on both at the same time, without needing to rethink them. Hint, allow enough room to work between them and bring in parts. And make it sturdy so it doesn't move around.
