Drilled backing plates...

[dawg]

anyone here have some photos of some nicely drilled backing plates? TIA...

Here are some. It's a bear to do them perfectly, takes lots of time to get the holes exactly in the right places. I had a set I bought on Ebay and they actually looked pretty good, but when you looked close some of the holes were off a little. I ended up putting them back on Ebay simply because I had too many sets at that time.

Those are pretty cool Don.
Just curious, is this just for looks or does it actually help cool the brakes?

I guess to some degree. The old hot rodders did it primarily for that reason, and some even installed some kind of scoop to direct fresh air over the brakes. Probably this modification came from the circle track racers because the brakes back then were very basic and they were prone to fading, so any modification helped.

Some even went so far as to cut away a lot of the backing plate, leaving just enough to support the shoes. Not sure how much that affected the strength of the backing plates though.

Later hot rodders did it mainly because they just look cool.

Here are a couple more. I like the look of the small steel scoops on 2 of those. '22

Me too Dodge. Obviously the man who did these is an absolute hot rod genius. In fact, I don't think any human could drill these himself, it had to be done on a cnc machine! I don't know who the owner is, but he certainly is someone I would like to meet, one of my all time heros for sure. Maybe Chip?

(PS: I didn't realize these were yours when I saved the picture, I really do like them Dodge )

I like the scoops and milled slots, that's kinda what I was thinking about...

Thanks...

Wow.... Actually, I can take credit for the work on mine, but the idea and basic pattern came from a car I saw at the Antique Nationals about 6 years ago. See the photos. And thanks again Don '22

Dude, is that a real Ardun with a blower?...

 

[22dodge]

Yes...

As far as I can tell, yes. The last time I saw the car in person it was running 2 Stromberg carbs.
It looks like the same manifold with the blower between the carb plate and the manifold flange. '22

I'd give my eye teeth for that mill...

I really like drilled backing plates. Some nice examples have been shown. I'm about to change my front disks to Buick drums on my coupe. I'm a little pinched for time so I probably won't get to drill my backing plates now. I'll get to it eventually though.

Come on Bill, after all the holes you drilled in your interior for rivits, this should be a walk in the park for you. Not only that, but you drill them straight...something I have trouble doing.

I know, I know. But I'm thinking about something a little different. I don't want to rush the idea and mess it up. I want to draw up a few designs first.
