You're an artist, Scott.

Thanks Taylor!
Chips ahoy! Oil cooler door actuator levers coming soon to a Corsair near you.

Good morning Scott my man. Take a look see here. Anything look familiar?
The link won't stay on the page I selected so look for the entry "By request, P-47's in Burma" on the list entries. Any idea what unit these guys were in?

Mark, will have to look for the insignia. Not the 33rd FG, 58th, 59th or 60th FS but right time and right aircraft with the P-38 as well.

I'm seeing posts stating 80th FG, 90th FS.

Machinist creed, just cut away anything that doesn't look like the finished part. Today was Side 1 roughing of the two pieces and got to Side two on one.


Next is to finish Side Two on the second piece. Then do the radius and finish the blade width. After that, we tackle the shape and contour.

Hey, I know what a BFP is, why, I even made one once - really! GREAT stuff man, keep it coming!!

After roughing both pieces, Op 2 was to machine the radius and set the base thickness.

Op 3 was to cut the web to the proper thickness by machining each side to keep all on center.


Next came lay out of the shape, saw cut, sand and finish



Next is to spot face and machine the slotted holes for mounting. There will be a steel bushing installed at the tip but I won't do that until I have the bushings.

Milled the mounting slots today. Waiting for the tools to do the spot face then bushings for the upper pivots and then to make the steel mounting bracket for the web. Geez, how long can a couple simple parts take...

Looking fantastic! What is the overall size of those? Is there a t-rail that could be used rather than milling all that metal?

They are 4" long and 3 1/2" high, 2024-T3. Probably is a Tee out there somewhere but past experience looking for special extrusions, minimum buys have been cost prohibitive.

The originals were castings but most pieces had alternative methods of manufacture allowing for billet forms.

Is it safe to mill these out of a solid block of material? I understand that you got to do what you got to do but are these parts going to survive their function? Nice work BTW. I'm a machinist myself but no longer do it for a living. Cheers!

If it's to replace a casting it's no problem generally. If it replaces a forging you need to check the material spec. But your usually fine. In WWII they didn't forge necessarily because it was stronger but because it was the fastest way to produce a complex part. That being said you need to read the print and know what your doing.

Most forgings of the day were 14ST material. As I said previously, the demand usually exceeded the supply so the military allowed for multiple methods of manufacturing to meet the demand.
Deuelly, you are correct, equivalent or better material characteristics are necessary and yes, we follow that principle as well.
