Scale Wendell Hostetler 30% Piper Cherokee Glass Fuselage Build.

Working on the servo pockets and hatches. The wing is rather thick so decided to mount the servos upright, or downright since they on the bottom of the wing. Pinned a fence to the wing made from scrap balsa. Using the router attachment cut .025" deep groove around the servo pocket, short pieces of 1/4" dowel hard points were added for the screws. After the glue cured the area was cleaned up with router attachment before cutting the pocket. I zip bit was used to cut the pocket and the 1/8" servo plate was installed with Gorilla glue. The hatch material was laid up on the recently constructed mold.
Mounting the engine today.

I like the way you did that with a router just have to remember the process when I need a servo mounted in a wing. Nice clean installation.

Thank you Snoopy.
Bungeed the Cherokee carrier to a step ladder and then bungeed the fuselage onto the carrier to hold the fuselage vertical while the position of the engine was adjusted. Didn't source the spinner yet so a 3 1/2" plywood disc was use to align the engine. Once happy, the firewall side of the standoffs were hot glued into position. The standoffs were drilled and tapped on the engine side only, the standoffs are drilled with a #21 drill for threading the firewall side to 10-32 once the final length is determined. After the glue cooled the engine bolts were removed one at a time and a long 1/8" drill bit with a 2" piece of 5/32" tube was used to locate the holes on the firewall. The 5/32" tube is just slightly smaller than the minor diameter of the 10-32 tapped hole. While the cowl was on measure the gap and decided to remove .050" from the standoffs. The engine was removed and final machining and tapping was completed on the standoffs. Another task that I don't care for is out of the way.
