The bulk head or firewall on this car was wood
I finished it using high quality artists oils, similar to the great masters, Michael Angelo , Turner and Constable. but it doesnt really fit in with Bling so i have covered it in hi tech pure aluminium alloy extruded and rolled sheet
Carefully applied amounts of Cyanoacrylate acrylic resin that polymerizes instantly when exposed to moisture in the air or on surfaces. ensuring a strong bond with the aluminium alloy
once cleaned up and the holes carefully restored using M42 (8% cobalt) Titanium-coated HSS drill bits
or..............
I stuck the original plastic part on a coke can and drilled some holes in it.
Now as usual my lack of a plan has stopped me as i dont know what to do for a finish. Because of the size i dont think i can engine turn this as i dont have the X-Y scope on my drill beds. If i polish it, it will look awful as the mirror finish will highlight irregularities on the surface ( i think) maybe i should try and see howe it looks ?

The turned look would match the IP.

Well i scrapped the first attempt but i got away with the second i think
i used a wire brush this time and some thicker alloy sheet i put a tube over the wire brush with just 1mm protruding to stop the wires spreading, its still not right, i must have lost count of the turns on the table after the first 4 rows so the pattern is bent. Its very difficult as the part is bigger than my table movement range so i had to move the part and re clamp half way through. It requires a huge amount of concentration, as you can see as the table moves across it covers the vernier scale both ways. That said if you were set up to do this it would be pretty straight forward.
Hell I say you nailed it! I mean how precise would it be?
In the movie The Spirit of St Louis they show a scene when they are doing that machining on the engine panels, they are doing it just like you are except they did not have a x-y table, they were moving the sheets by hand. Did they do that on the real one? Beats me but since Lindy was on the set advising the filming I wouldn't doubt they did.

When this kind of patterning is done on watches, it is done entirely by hand and Mark I-C eyeball. (C is well trained and calibrated)
Something you could do is to take a fine sharpie marker and draw some measured lines on the surface before starting to help guide the process. The patterning would remove the lines as you go along, then when done, some thinner would wipe away the rest.

Thanks for the input. The sharpie thing would be worth exploring.
I think as i have only done this twice and i was winging it, i would improve greatly with another couple of attempts given this firewall is 10x better than the dashboard its hard to align things because while you are producing a row of circles across the work you are trying to align to a disrupted pattern above the row. There are no circles above as each new circle disrupts the one above i you see what i mean and the line you are trying to follow is diagonal..
This is a 1950's 14 inch engine turning machine.
its hard to work out what's going on but my best guess is the wheel on the left is the power (manual) the item on the right seems to have gibs so it could be a vertical guide. the pullies lift the square plate with the circle on it ..the tool post is on the front cross slide... but i cant see what turns but what a brilliant bit of kit i love things like this. Of course not all engine turning was circular so the above is misleading.
This looks to be a very similar machine
anyway if i get any further into this i will be here all day or week or month
