More thoughts on the stab tube screws...
I went down to the shop and looked at the one stab I have mounted. It only has one of the two 6/32 screws into the plywood root rib tabs.
I can not detect any play in the stab tube. If I try and lift up or push down on the stab I can twist the entire fuse, but the stab is not moving on the tube or away from the fuse.

Sorry long day... sucks when the plumber disconnects the water to the wrong house! That's 8902 NOT 8904!!!!!!!
I was NOT planning on adding that bolt.
We don't trailer our planes and will need to remove the stabs each time they are transported.
I don't think Dave added those bolts. Dave am I wrong?
I can add them without a problem, my idea is to turn aluminum plugs to fit in the end of the stab tube, drill/tap them to 6/32 and add hard points to the bottom of the stabs.
The stab tube would need to be slotted a little to accommodate any incidence adjustment.
Nope, I don't use the bolts through the tube in the stabs- no problems. With the modified stab attachment (like Walt does and like you are doing) I feel it is locked down and no need for the additional bolt through the stab. Besides, they are a pain in the butt and can get a little "ratty" looking over time. That's when Wayne knows it's time for a new plane.

Hi Dave, I'm doing fine. Cody is a junior at Worcester Polytech and I'm going to put on the Granite State IMAC next year. Cody has been flying a Carden 330 w/DA150 and loving it. School and work has made IMAC a secondary priority until after graduation. Flying advanced had a 1st, 2nd, and 3rd. He is going to try to make a few more events next year. How have things been going down your way?

Seems to be 2 very different opinions on whether you need the bolt through the stab tube when using the ply tabs on your stabs. Anyone else been doing it without a tube through the stab? I thought part of the reason to have the ply tabs was to eliminate the bolt through the stab tube.

I know the updates seem a little slow. Now that the parts are getting bigger I have to do one plane at a time then move it out of the way to repeat the steps on the next plane.
The square wing dowel placement was harder then I thought. The main wing adjusters yield a little more then a half a degree in either direction so I had to make sure the adjuster was centered, then adjust the square dowel perfectly at 0 degree incidence on each wing.
After a lot of test fitting I got that job done.
Next time I would place the adjuster a few inches closer to the wing tube.
The stab adjusters yield almost 2 degree's in each direction. With the 3/8" hole already drilled in the root rib it was a simple matter of drilling out the foam and placing the dowel.

I would say the little bolt that takes no time to install is like a seat belt. You hope you never need it. I saw a guy land his 35% Extra through some pine trees. Plane came through with rt stab bracket ripped out of the fuse. Left ele linkage was broken. Poor little bolt that takes to much time to install was the only reason he was able to land the plane. In this case 10 cent was holding up 5000.00.

Seems like overkill but I will include it just in case I fly through a tree, you never know.
I cut plugs out of some type of delrin or nylon I had in the scrap box.
Drilled and taped to 6/32. Glued balsa plugs inside the wing tube to prevent the plug from falling in. Slotted the wing tube, and cut 2 slits in the end to form a tab that could be bent up into place to keep the plug from falling out.
Remember the plug needs to rotate since I have the adjustable incidence.
Cut the 1/2 dowel, drilled and sanded on end to the diameter of the wing tube. Drilled a hole in the wing tube. I will glue the dowel in place when I get the other side done.

very nice. Now you can fly through trees or other large obsticals with confidence.
