Bob,

You have made me curious. *Here at the Nampa, ID airport there is an HP-11,
HP-16T and my HP-14. *(We need a RS-15 and a airworthy HP-18 to complete our
collection.)

Several years ago I replaced the badly corroded drum brake wheel on my HP-14
(http://www.soaridaho.com/Schreder/HP-14/N990/N990.html) with a *500 x 5
disc brake wheel. (Matco W51-1.25 ) *This winter I replaced the hard rubber
tail wheel with a Matco 6" pneumatic wheel.

I know Brian Case has a 500 x 5 disk brake (even though I don't remember the
brand) on his HP-16T. (http://www.soaridaho.com/Schreder/HP-16/N16VP.html)
Now I am wondering what size wheel is on Jan *Zatloukal's HP-11.

Paul,

You've probably already thought of this, but is there any reason you
can't just take your 40-19 wheel halves to a machine shop and have
them carve the center seam until the width is as you require and then
redrill the valve stem hole? I could do that on my 9x20 any Monday
through Wednesday evening in Cupertino. Or if you want it blessed by a
racing wheel and brake firm you could probably have Mike Morse at
Vintage Brake do that for you.

I don't know of any HP-11 with Cleveland brakes, that'd be a really
tight fit. The HP-11 gear well is sized for the obsolete 13" dia
13-500x4 industrial tire with band-on-tire brake and won't really take
the 14.25" 500x5 without some heroics. The one HP-11 I saw with a
500x5 (N1954 owned by the late Ray Duncan, later torn up by a tornado
and I don't know where it ended up) had a Tost 5" wheel and brake.
These days most HP-11 operators use either cheap 400x4 tires with
suboptimal ground clearance or expensive 500x4 aircraft tires (about
$200 ea these days) used mostly on Ercoupe nosewheels and AT-6 Texan
tailwheels. The expense of the latter makes it painful to use the band
brake that tends to wear a stripe down the center of the tire on heavy
braking.

I think that the ship you refer to might actually be an HP-14 or
later; starting with the HP-14 Dick designed everything around 500x5
tires with a variety of MATCO (originally Roshenan) and later
Cleveland wheel and brake components. The HP-14 gear is beefier and
more robust than that of HP-11, and appears with only minor variations
on all subsequent HPs and also on my ship.

For some HP-14 kits Fred Roshenan supplied a slick little drum brake
similar to the Tost 5" drum unit, except with wider and larger
diameter contact area, hydraulic actuation, and Bendix pistons and
seals that you could get from any NAPA car parts store. Fred also sold
a neat package of wheels and brakes for Alfred Scott's Falco kits. He
basically gave away the store making stuff like that for homebuilders.
Of course, that ended when MATCO bought him out and started running it
like a real business.

Thanks again, Bob K.

I have a couple of old Clevelands at the shop, how would I identify
a

40-78 by sight?

Thanks, Bob K.

Good question. It's a 5 x 5.00 Cleveland wheel that has a smooth,
clean looking exterior on the flanges of the rim that hold the tire
bead. Total width inc disc is 5.155" or so, outer rim face to outer
disc face.

The older style (40-19 & company) has a pattern of indentations on the
exterior of the flange, making them look like classic aircraft wheels.
Both styles are held together with 3 bolts and share the same seals/
bearings...Total width on 40-19 is around 5.3"w/disc (just too wide
for my fork : (

BTW, my 40-19 is the unused 1/2 from a set. The other one went on an
HP-11 long ago...

Thanks!
