A WORD ABOUT INSTRUMENT FIT. THE BOLT PATTERN AROUND THE GAUGE HOLES IS EXACTLY THE SIZE AND POSITIONING CALLED UP ON THE ORIGINAL BOEING BLUEPRINTS. AFTER CREATING A 3D MODEL OF EACH OF THE THREE PHENOLIC PANELS, A DXF FILE WAS MADE FROM THE MODEL. THIS FILE WAS USED TO LASER CUT A 1/8" ALUMINUM TEMPLATE OF THE PANEL, WITH THE CENTERS OF EVERY HOLE VERY ACCURATLY LOCATED. THESE TEMPLATES ARE USED TO DRILL THE LOCATOR HOLES FOR ALL THE MAIN GAUGE (LARGE) HOLES, WHILE ALL THE SMALLER ONES ARE DIRECTLY DRILLED THROUTH THE TEMPLATE. SO EVERY PANEL IS EXACTLY THE SAME, WITH VERY LITTLE MARGIN FOR ERROR.

 

 

AFTER A GOOD SANDING AND TWO COATS OF FLAT BLACK PAINT THE FRAME IS ALMOST READY FOR FINAL ASSEMBLY.

 

THERE HAS BEEN VERY CLOSE ATTENTION TO THE DETAIL IN THE ORIGINAL BOEING DRAWINGS. HOLES FOR ALL CABLES AND HOSES HAVE BEEN LEFT IN THE PROPER PLACES IN THE VERTICAL RIBS AND BOTTOM PANEL.

AND NOW THE THREE PHENOLIC INSTRUMENT PANELS ARE ADDED TO THE FRAME. NEXT THE INSTRUMENTS WILL BE ADDED.

 

FINALLY THIS AFTERNOON I GOT ALL MY INSTRUMENTS INSTALLED. STILL MISSING A FEW SCREWS, BUT I HAVE A BOX ON ORDER. DON'T HAVE A GLOBE TEST BUTTON YET, SO I PUT A PANEL LAMP IN PLACE OF IT FOR THE TIME BEING. THIS IS A HUGE IMPROVEMENT OVER MY FIRST LUAN PLYWOOD SHEET. I THINK I OVERHEARD THE VOLTMETER TALKING TO THE PDI GAUGE AND IT SAID "WE'RE BACK HOME AGAIN"
