Dunstall Norton disc pads

Bernhard · Nov 7, 2016

I must be dreaming of these prices for a set of 4 disc pads;

As I understand it were these pads off of or the same as a British car made in the 1960s :?: :shock:

Sure it would be nice to find a supply of currently made pads for a 1960's car, but until someone springs the info, I make my own out of inexpensive emgo commando pads. They do need to be thinned down to fit, as the pad material is to thick for the Dunstall dual disc calipers.
My cost $10? $15? a set + labor and machining time. :mrgreen:

I take it you just use a lathe to skim them down, and Mig weld a wire for the tabs :?:

Band saw the commando tab off.
Lathe turn off the steel back plate to size.
turn around piece
Lathe turn off the friction material,
Face off the friction material to correct thickness.
Drill hole in edge of steel. Put wire in hole
Stake wire in place. If welded I would TIG not MIG
done
There... saved $235

Good on you, nothing like a bit of D.I.Y to save you money

What much does a TIG welder and metal lathe cost? Will a soldering gun and file work?
lol :roll:

I do get your drift, but you should ask around to find someone who has a lathe and will do cash in hand, Ditto TIG welder...... :roll:

Thanks for the tip Dave. I had read you could machine them from a ZI round pad, but Commando sounds even better - because I have a few new ones sitting around!

Im actually jealous, I've always wanted a metal lathe. A friends dad owned a machine shop and I got to make a few things. I have a acetylene welder, a mig welder would be nice, there fairly cheap now.

I have got 4 of the old type asbestos pads for my 2 AP Lockheed callipers, which should last for the rest of my life considering the number of times I race these days, I've tried a few different pads, however none are as good on the hi-speed steel discs I use. I couldn't get enough heat into the carbon racing pads to get them to work. I don't know of anything which is really effective with a chromed disc. I threw mine away and replaced it with two off a Suzuki GS something.

The maker of those Dunstall pads is Ron Frattarelli. I'm sure most of you have heard of him.

Ron's work has never been cheap, but it's always been top notch. He has singlehandedly saved my Dunstall twice, 30 years apart.

I've owned my '72 Dunstall since '86. I bought it from the original owner (a family friend). It is titled as a Dunstall and was bought in the UK in person from Paul. I have all of the paperwork from its purchase as well as memories of polishing it when I was 8. It has most of the Dunstall tricks, with the exception of the bodywork. It was called a "Sleeper".

I'm curious how you'd use a metal lathe to make round pads without some custom tooling. Id imagine you'd need to find a way to attach the pad to a backplate (adhesive?) I don't see how you'd do it with a chuck. I'd also think thinning the pad would be far easier in mill. FWIW: I have a lathe and access to many mills, and I just bought pads from Ron. His experience is worth the money.

Many thanks to the posters in this forum. The information here is great!

You should look more closely at the pic in the flea bay advert there are little holes in the centre :!: :shock:

there is supposed to be.

I'm not saying that the Dunstall pads aren't great...but. The price is WAY steep to me. Friction material and it's application is not rocket science and should not be priced as if it is. I've used Metal Frictions, Inc. in Seattle, WA. since 1972.

Give them a call to discuss your needs. They will bond new material onto your shoes or pucks for a very affordable price. Racing or recreational, these guys know their stuff!

Yes, that is exactly how Robinson made these for Dunstall in the late 1960s; I remember many moons ago an article in the m/c press how he made the disc pads-from of all things a Triumph Herald/Spitfire :!:
