Brief Description: Set 4 rivits forgotten during build on bottom skin
1. Started off with the canopy frame tweeking. Removed several times to work on bending the aft bow some so that the distance betwen the t-rail and the frame bow is 5/8-3/4 inch. I barely had 3/4. Now that I tweeked it, I have a solid 3/4". Id like to end up with a 1/16" less and can get that during the canopy fit I think.
2 There are 4 holes in the bottomskins in the center spar channel that were forgotten. Now they are a challange especialy since I have the center control column installed. I lightly countersunk the holes after running a #40 drill thru.
3. I let Brenda run the gun and I was able to lay a bucking bar in place on the rivit and hold fairly well with my finger tips through the control column hole. Got them set but the shop heads are not the best looking- pretty crooked. Believe Ill leave as is and go on.
Also spent time wondering how to proceed on the canopy and some other things ut didnt get anywhere. Maybe tomorrow.
Note: NAS rivits used are also known as OOPs rivits from Avery tool. They just have a smaller manufacture head so require a smaller dimple or countersink. Works well here I think. Thanks to builder Steve Riffe!
