[C38] Autohelm parts

We just did ours last  spring, and used an old PCM/Mylar drawing, that
we wrapped around the post and worked down into the opening.

Mark, Nice dodger, The color scheme looks great!

I'm also curious about how the lens bolted directly on the window frame
had worked for you??

Hey all...

Speaking of auto helms .... Does any one have any Autohelm ST4000 parts?
My wheel drive actuator went up. Well, it started slipping, and then in
a blow one of the internal roller ring posts snapped off and caused one
of the rollers to rattle around inside the wheel ring unit...basically
disabling my steering completely. (was fun pulling the ring and the
wheel off to ditch the whole thing while underway!) anyway, my control
head and power supply work just fine..., and up till about 10mins ago
the actuator motor did too (stupid me pulled the motor off the ring only
to see the internal gears go flying...guess I can put that back
together)... but my wheel drive actuator is beyond repair. so I'm
looking for a wheel drive actuator ring, either with a motor, or with
out.

Anyone got a box of parts laying around? Or know where I might find one?
Do I really have to get a whole new system?

Oh yea btw... Found a nice canvas guy in Baltimore that just did a
custom dodger for me, and is working on a complete bikini and connector
too. Good price, very accommodating guy. Charm City marine Canvas.
Thought I'd pass it along.

Hey Phil Gay... A big thanks to you for sending me pics of your
dodger... They helped me design mine. Pic attached.

	 I have the Type 1 (12in stroke), so as Davd pointed out,  a
small modification might be needed to the rudder stops, in order to make
it work, but not that big of a project.....

	I was planning to install it directly to the radial wheel, with
only a 8" radius instead of the 10" tiller arm, but still it should
work.. I hope!

	 This unit came with  a complete Autohelm ST6000 autopilot, but
is that old  (around 20years), that is not NMEA compatible, and that's
why I want to remove the wheel pitlot assembly and install it with the
ST4000+ display. Despite what RM support said, now I find it really hard
to make it work like this, but I'll give it a try. As Tom said, the
wheel pilot is very easy for connections and maintenance, but despite
the patented Troncalli's shock cord solution (which BTW works great most
of the time!!), the wheel pilot slips when the wind is blowing hard and
the weatherhelm increases...... So the linear drive should be more
reliable...

	 I've heard great comments about the Nexus and Simrad/
Robertson, but because of the price, they are out of the question. If I
don't make the linear drive work, I'll stick with the wheel pilot, or
maybe I'll just install both autopilots, hopefully, the new 20 years old
ST6000 might work and I'll have a very good back up.

	Have someone installed any brand of drive unit directly to the
radial wheel??? Edson used to reccomed it, but  years ago, they changed
their mind, started reccommending the tiller arms that they started
producing.

	Max,

	Do you know if it is a Type 1 (12 in stroke) or a Type1L (16 in
stroke)?  If it is a Type 1, my notes indicate that it rated for up to a
22,000 lb boat, requires a 10" tiller arm, and it has a maximum of +/-35
degrees of rudder travel.   The 1L is good up to 33,000 lbs, requires a
16" tiller arm as is also limited to +/-35 degrees.

	SuperStar's rudder has about 90 degrees of travel (+/-45), so if
your boat has similar range, you may have to modify your stops on each
side so that you don't have a problem when the linear drive is in
bypass.  I would think you could be able to make the Raymarine unit work
on a 38.

	When I did my research, I concluded that the absolute best
solution for SuperStar would be the Nexus/ComNav HP-40 integrated linear
drive (or the AP-23 with a separate pump), as it is fast, powerful and
has up to +/-50 degrees of travel with the specified tiller arm length.
I have not yet purchased a Nexus drive unit, so I can't tell you about
any firsthand results...

		I got a new one of this for free, and according to
Raymarine Support,  it can be installed with my ST400+ wheel pilot
display.

		Does anyone has installed one of this below deck drives
on a C38 ?? If so, any installation pics or recommendations will be
appreciated!
