Once again, you never fail to impress.... There's lots of questions to ask, but for now All I can say is thank you for posting and sharing so much.

Very cool, Jim.

Nice job there brother! I like the buck for the gas tank. I was very impressed with Andrew's work on the valve covers using that expensive tool. I wish I had taken more time to look at the hood and hinges, they have turned out real nicely.

Default Flaking

Haven't noticed machine tool flaking on a car before. (cam covers) Was that the original process? What is the theory behind the long handle on the scraper? I have always used a short one that would nest in my arm pit.

Wow, Jim, this sure takes me back to my Bugatti resto days.
!/4 elliptic springs, cool steering box, barrel hinges with the lubed ball bearings (used spare bearings w/valve lapping compound to clean up the plating flash).
Always like a nice walnut dash board, plenty of figure, w/high gloss.

Hood sure got the louvre work - like the T57 Atalante engine bay sides.
Scraping gives the motor its look - (decades back there was a Bug guy - Bunny Phillips, who used to do hellacious jewelry-like engine scraping on the Bug engines.)
Hood hooks - classic curve-end tubes hooked onto the ball ends. (Used to paint it all nice and then set the nickel-plated copper rivets with a little ball pein and with a hand set up on topside. 4 taps, done. Should maybe have the buttons on the top panels, for when the hood lays open??)
Nice hidden hinge work on the sides. (Used to hand cut and file all the hinge blanks, then wind them up in the D&K press brake. Then put a little bit of crown in the top hinge hood flanges, 'cause setting all those rivets expanded the flanges down to sub-flat .... urk!)


Loads of work here, Jim. Serious accomplishment.

Hi Jim,

Very Cool work here, I've just learned some stuff and I like those special Steel Cap Thongs you are wearing on your feet.

Default Metal scrapping, flaking & engine turning

The question was asked by Bill Funk if they originally scraped the engines on Bugatti's and the answer is yes. The apprentices were given the job of scraping, flaking and engine turning the firewalls. Some were well done and some were poorly done. It was all done with by hand and was a tedious and labor intensive job. This is the original pattern which was on this particular car which we found by taking a sharpening stone and water and just skimming the top surface. The pattern is made in squares with the shape of commas which you can see from a close up photo. The castings on the Bugatti's I have worked on were very porous, unlike British castings, and I'm guessing by putting on decorative scrapings it helped hide all of the flaws. When polishing the covers there were 1/8" craters with dirt and slag in them which had to be cut out with a dremel tool. I then used a ball dremel tip and undercut the hole so i could put in a soft rivet and mashed it in the hole. After filing and sanding I polished the piece and you could barely notice the spots and after the scraping was done they were not noticeable. Other parts of the engine were repaired in this manner.Name:  10-17-18metalscrapping 006 Large e-mail view.jpg

Flaking is done with a straight scraping pattern done randomly. The engine in the photo is of a 1931 T46 which has flaking on the block and engine turning on the water and oil jackets and the firewall. I am replacing the water jackets which are cast and need to be finished to match the lower oil pan jackets with engine turning. The other photos are of two power scrapers I have which have the straight pattern and half moon pattern. The shape and size of the patterns are determined by the speed of the machine and the speed you move the machine as shown by the sample piece.Name:  10-17-18metalscrapping 006 Large e-mail view.jpg

The last decorative pattern is done on the firewalls. The turnings are in alternating rows which zig zag and really don't look to good. The firewall shown is from the T57 and has the chassis number 57314 stamped on it.
