After calling the T88 people I confirmed it is perfectly ok to remove the "squeeze out" epoxy with a heat gun and scraper. I tried it and it works great!

Ok so while laminating the plywood to the wing spars the "squeeze out " epoxy was making a mess and was a bear to clean up. What I discovered was to use blue masking tape around the perimeter. Then the epoxy would drip onto tape. Wait about 2-3 hours. At that point tape removes easy and epoxy no longer runs.Remove tape. Nice clean bond with very little clean up. Here is one rear spar ready to clean up and bevel. The other drying! Also I did some experiments. Found that one gallon of liquid (approx 8 pounds) spread over two cross members shown here is the perfect weight to laminate. Good bond. No glue starved joint! Notice before and after tape removal in last two photos

Big,  How are you planning on beveling your spar?

I put a lot of thought not it. I am afraid of using the table saw. Even with help and feathering boards. A small slip and they are ruined. I think I am ging to make a "shooting board" and hand plane the bevel. Unless anybody had a better idea

My woodworking "guru" friend cut mine on his table saw. I did very little to help and as far as I'm concerned they turned out fine. We had made several test cuts on scraps that were previously cut to the dimensions of the "raw" spar sizes. As nerved up as I was about having them turn out just right, I started handing one of them to him with it facing the wrong direction! Yikes!

Your results may vary, so do what you're comfortable with.

Ok.... I decided to use the table saw to cut the bevel. It went a lot smoother than I expected. I still had to hand plane the rear spar to get a nice fit on the ribs! But wasn't too bad at all, starting to look line an airplane part! No weight loss since last entry

Since I opened my big mouth and suggested the table saw would be OK, I must say I'm relieved it went well for you too! It's a big event when something you've been working on so long starts looking "airplane-like", isn't it? Makes all that effort worthwhile and gives you something to admire as part of your soon-to-be airplane! Congrats!

I think the plywood you have on the end of the wing is supposed to be longer to include the shape of the nose rib..

Oh no... I think your right about that.  Guess a call to Dave at minimax in the morning to see what he recommends for a fix. Any body else mess this up? What was the fix?. Yes lake-Harley very rewarding as I progress

I have acquired an engine. It's a hummell built 60 up with 145 hours!  Has front mounted starter. With single slick mag! I plan on pulling the heads and going to dual ignition.

If you're going to use wingtips you can just add the other piece and put a scab of the same plywood over the joint.. Maybe a good excuse to use wingtips if you hadn't planned to..

bigbrixx1....will you PLEASE turn your camara over?   The top of my head gets sore from standing on my head to get the proper perspective of your photos.

Keep on making progress on your build!

bigbrixx1.... your most recent pictures on my screen make it appear your engine is bolted to a pallet that's attached to the ceiling. Ain't no big thang, just hard to look at.

Ok back from vacation. Finally looked at the pics on my regular computer. Now I see the upside down ones! Funny the ipad and iphone correct them to upright but the computer does not! I will try to be more diligent!
