There seems to be a concern about the knobby motorcycle tires I have on my
piet.
I know most aircraft have smooth tires and it lets you slide on the grass.
But those same
smooth tires don't slide much on asphalt runways. Maybe later I will opt for
smoothys but
I think that there shouldn't be a problem with the ones I have now. I don't
plan on doing a
lot of heavy cross wind landings for a while. My early flights will be in
calm weather. And if
I do get a cross wind, I'll land like it was asphalt. I thought I would
throw this out and get a
feel for the groups opinions. Thanks as always.

Hey Corky, you know it has rained wayyyy too much in 'Ol Virginia when I was
working on the Piet in my hangar today listening to the thundering rainfall
(all day) and I looked down and about a 4" crayfish was crawling across the
floor at my feet.
I'm gonna convert the Piet fuselage into an ark, might get some use out of
it.

the pics of the torque tube looks almost like the
parts were brazed, not so, I hope.

Del,,, Originally,, the control tubes were brazed, then I redid them after
learning that was a no no. That was another pain in the butt lesson I
learned but the knowledge never stops on here. So what do you think
about the tire deal?

I don't know the answer to that for sure, I can't
think that there would be a problem, my sonex has
treaded go cart or garden tracter style wheels on it.
and it works fine

I don't see why knobby tires would grip any different then treaded or
smooth. Actually knobby tires grip less on asphalt then smooth tires do.
When was the last time you saw a street bike with knobby tires. You
could always cut off the knobs with a razor blade and smooth them down
with a disk sander to make smooth tires.

I think it needs to be said again so no one else has to learn the hard
way like Carl did.
If you use 4130 steel it is prone to cracking if you braze it. Do not
braze 4130. Yes I know bike frames are built out of 4130 and they are
brazed with a lot of success but if they brake you will most likely not
be killed. Ever book on aircraft welding I found says not to braze 4130.
These same books also say you should not weld a joint that has
previously been brazed. The braze material will contaminate the molten
metal and make a weaker weld. Now, if you use 1020 steel like the plans
call for you can braze it just fine and it will be good joint. There is
nothing wrong with using 1020 steel to build an airplane as long as the
plane was designed to use it. A lot of the antique airplane are built out
of it. The only part that BHP calls out as needing to be made out of
4130, that I can find, is the rudder bar. Remember, even though most
people are using 4130 for everything IT IS A CHANGE FROM THE PLANS so you
need to due your homework on how this change will affect your building
process. And my study of this change is to weld 4130 in a draft free
area using a welding method that heats up an area of approximately one
half to one inches on each side of the weld bringing the temperature up
slowly and after welding you should allow the material to cool slowly in
a draft free area. Knowing this I choose to gas weld all my parts and
reheat the weld as well as an area around the welds to release any built
in stress. I do all me welding in my garage with the doors shut to keep
the drafts down. I'm not an expert on any of this so you should do your
own homework to satisfy your own fears.
Sorry, I don't mean to step on any toes but his is one of the things that
comes up often in the list archives and I just wanted to make sure any
new people out there get this valuable information.

I would think the knobbies would be better for
crosswind as the knobs would tend to " walk".
Each one would grip, bend, release in turn.
There's a certain amount of this with any tire
but the knobs are independant of each other
and thus have a greater range of movement.
Also the tire casing's deformation in the direction
of force will be greater with bias ply tires than
radials. I remember when all cars had bias and
they would pull badly when doing things like
crossing train tracks at an angle. So for cross-
wind landings bias might be better- built in
castoring.
