Sopwith Pup how to burnish engine turning finish in aluminum aircraft panels

[WarblesOnALot]

@ripfree G'day... Nice clip. Good Technique. I've worked on a Replica Sopwith Pup, y'see. (Search '1975 Skycraft Scout' to see that.). My Dad's Uncle trained on Pups in 1918. (Search 'ANZAC Day -Long Version'). I'm unaware of ANY Pups, in Service, with Machine-Turned Panels. It was a Post-War US Fashion, see James Stewart in Spirit of St Louis. Why didn't you glue a Cork to a Hand-Drill, & use Lamp-Black as an Abrasive ? That's the traditional way... Ciao !

Thanks for sharing your work, i just tried this today, to immitate the dash of my 79 trans am for a radio delete plate. I used i wire brush and it did not turn out as good as yours. I just ordered a Craytex stick and i am going to re-do my plate next week. Your video was a great help!

Cratex rubberized abrasive stick - 0106C 5/8" - correct?

the video is out of center

This was a terrific video! I have a 67 Impala Super Sport with brushed aluminum interior parts.  I think I am going to use this method on them for something a little different. How do you hold the sheet steady while also controlling the up and down motion of the mill?

thanks a million for sharing your tech with us it will now go to my K5's dashboard..

[ripfree]

You're welcome. How about posting the insturment panel for me to see?

[porkpig350]

shortly i am making an attempt on it with vgc

That's some nice work!  I've been looking for any type of guidance on how to get an engine turned finish and there's not too much out there; I'm afraid it's becoming a lost art.

[ripfree]

Yep. Basically had to rediscover the process. I too found nothing really out there. In fact, I didn't even know it was called "engine turning". Since then, I've been to a restaurant with stainless steel tables & chairs. Each table is engine-turned. Amazing.

marvellous technique- filing that away for future reference.

Laying up after using contact cement- when the glue is DRY, use poly plastic between, position part, remove poly- some people use strips of poly- which of course has to be really clean.

Thanks again

[ripfree]

I've used the poly technique you describe, but with a variation. If you place a poly, folded in HALF, you can tug on one of the free ends and pull the whole sheet out in one motion, leaving the metal still positioned.

excellent tuition on engine turning and great credit to you for sharing with us what obviously took you hours to..find how..,one thing occured to me during this demonstration if you cut the template 1 inch over size would you not have to worry too much about the end burnishing ,then cut to required size

[ripfree]

Of course, you're correct. Oversize would have prevented any concern about burnishing with asymmetrical side loads. The cratex seemed to minimize this problem, and the sharp edges just exposed more abrasive rubber, making the stick cut even better.  you could even say it helped.

Good Job! Is that a 1/3 scale plane? Balsa USA?

[ripfree]

yes, 1/3 scale BUSA Pup.  Thanks

Well done demo!
