It has been some time since I last worked on the RV. Other commitments have gotten in my way in the last year (or two). I finally got the RV back out in the garage and am slowly trying to figure out where I left off. You wouldn’t think that it would be that hard, but...

Nothing substantial here, just proof the fuselage is back in the garage.

I started looking at the F-680. On Drawing 33, it shows that the block needs to be notched to eliminate interference with the F-742-L aft seat floor. The drawing shows that the notch is 1/16”. After I notched it to the drawings specifications, something didn’t look right. Usually the UHMW blocks have been cut to exact dimensions. However, on the F-680, I noticed that the block dimensions did not match the print. Overall width of this block is supposed to be 2 5/32”. However the block was wider than that. So I cranked up the CNC Mill and milled the F-680 down to dimension as called for in the print.

The final dimension of the F-680 block. Not shown in any pictures, you also have to drill two holes in order to mount the flap bearing block. Be sure to reference dimensions in drawing 33. All I have left is to cut this in half so the flap actuator can be mounted inside the block.

I also cut the F-623A-FWD and F-623A-AFT attach straps. They are cut from 0.032” aluminum. Dimensions are listed on drawing 22.
