New caps are
in... scroll to bottom
This article covers some of
the information about FR/ARE center caps that has been floating
around on the internet. I have a picture of an ARE center cap
here. You can see that they
are different from the FR caps with a hex design on a round base.
Either cap will, however, fit either wheel as the mounting holes
in the wheels are similar. Actually both the ARE/FR wheels are
extremely similar in construction with the exception of the cast
in FIAT ROOSEVELT lettering on the backside of the wheel and
the placement of the valve stem. The FR valve stems are in the
center of the spokes on the inside of the rim. The ARE stems
are on the outer rim facing slightly outward. The AR stems are
decidedly easier to fill with air than the FR stems, but the
FR stems are less noticeable and less subject to damage. Recently
I've seen stem placement on both wheels in both places, so this
may be an indication of whether the wheels were early or late
manufacture rather than which series. Here is a picture
of an AR wheel recently sold on eBay. You can clearly see
the cap on the ARE wheel is hex in shape.
Alvon Elrod has been working
on a set of ARE/FRE wheels independently. They are polished,
painted and tires are mounted. He has also done some careful
measurement of the two different styles of wheels and has come
up with some striking differences. There are pictures of his
progress and some additional information about the differences
that he has documented with his wheels here.
About the caps... Most sources
for the caps have all but dried up. I know, I've checked. I purchased
two caps from Chris Obert used and two caps from Canadan that
were mint new. The picture is of the mint new cap. Chris was
charging $25 a piece for used ones (I bought his last two). And
they were in really "used" condition. I found two brand
new ones that Dan had in Canada and had him send them to me.
I'm trying to duplicate the "look" of the original
while improving the wearability of the cap. Bruce Matthews at
the Bin has some nice black Fiat logo stickers that fit well
in the center recess of the stock caps, and this might be an
option on the reproductions. An example of the black cap is above.
The caps are made of plastic with a
bright chrome plating. There is a single screw that goes through
a metal circular plate that is on the inside of the wheel. The
screw passes through the hole in the plate, the wheel, and then
screws into the plastic cap to hold it to the wheel. The plastic
is subject to damage from tire tools and the screw hole stripping
out. The plating on plastic is.... well you know how durable
chrome on plastic is. The top of the cap is recessed with about
an 1.5" flat area that contains a red/chrome sticker disk
with the fiat logo. The red sticker lasts only about a year outdoors
and becomes a blank shiny chrome sticker rather quickly. There
are two concentric rings outside the stick on that are raised.
The idea is to have a machinist
create the plastic cap in bar stock in aluminum or stainless
steel. None of this should be difficult to reproduce. I won't
know what they will cost until I meet with him and go over the
project. The way the CNC machine works is that all the expense
is in the programming. The cap has to be measured and rendered
on the computer. Then the dimensions are downloaded to disk and
loaded into the milling machine. The aluminum is only a couple
of bucks! The more that I have made will really bring down the
price of the center caps.
The machinist is retired and
a car nut, and likes to do this sort of project. He does charge
$50 an hour for his involvement, but he is good and doesn't mind
putting in a lot of value added touches. For example The setup
charge for the bolts was $90 and he only charged me $50 to do
all 16 bolts. Additional bolts will only cost $3 a bolt. The
setup information is stored on a disk for the CNC machine. He
had to purchase a special chuck for his lathe to chuck up the
hex heads so they could be accurately machined.
This
was going to be my winter project for the car. The wheel caps
were on hold for a while, but there has been some interest from
others in putting a couple of sets together, so I'm ready to
go down there and rattle his cage to make some up. I still have
a couple of wheels to restore and polish. Then a set of Goodrich
205 s need to be mounted and balanced. The budget is taking a
bit of a hit here and will take a while to recover. Everyone
should have a new set of caps before Christmas 03. Happy holidays!
I've
had a couple of people ask about how the cap is attached to the
wheel, so here's a picture of the back of an original cap. Not
really much to see. There is a 5/16" plastic post in the
middle tapped for a machine screw and three smaller posts dividing
the circumference in thirds to help center the cap in the hole.
The metal plate goes on the back and is held in place with the
machine screw. My theory as to why all the caps are gone is that
the plastic center post splits from age and stress and the screw
lets go and the cap falls off. The replacement caps are solid
aluminum and are tapped for a 10-24 bolt. The disk will do the
centering job nicely.
The
new caps look exactly like the old caps except as I mentioned
before, they are solid aluminum and near indestructible. Overall
they hey look better than expected. Jim did beautiful work. Above
is a group shot of them with the decal sheet. Directly above
is the aluminum blank right after machining, and to the right
is a picture of the new cap with the stock FR plastic cap. The
new cap is just as bright as the plastic one, even before it
is polished ,as the chrome plated plastic. The dimensions of
the new cap are within +-.0015" Close enough for a wheel
cap.
The backing plate is zinc coated
steel with a stainless 10-24 bolt rather than the self tapping
screw of the original. The concentric rings are there as is the
subtle taper of the sides. In every way this is identical to
the original. Below is a picture of the new cap alongside the
original. As you can see, they are identical in appearance, though
no one who hold both in their hands will be fooled. All that
is left to do is reproduce the sticker and tap the bolt hole
in the back and they are ready to be sent out. Congratulation
all of you that bought them.
