I figure I'll start 2012 with a notice, an admission and an executive decision (albeit a somewhat painful one.)
The notice:
I’ll be gone until January 10…I’m going south to play with my kids and
grandkids for 6 days, and to see if I can warm up my feet from standing on the
concrete floor of my unheated shop and dry out the moss growing on my
body. So for the next 7 days the
factory’s closed.
The admission:
Getting away from this enterprise's simple beginnings has been fraught with tough lessons and not much fun. Making the TerraTrike adapter bracket has been way more a stress
test than a design project. The
first version bracket was a perfect fit for Rovers but not for other models.
The second version (at least judging
from Dave McConnell’s Tour) works fine on all TerraTrike models. To make it a bit more compact I
down-sized the bracket slightly from Dave’s type 2 version and made the first batch of the
new type 2's.
Just before taking the new brackets to be powdercoated I heard from Mark Peele who was testing out the type 1
version. He had some troubling news.
The short 3” piece of thin wall tube on the bracket actually tore from
the torque of the neck rest and “T” tower on the mtb stem. The weld held just fine, but the thin wall tubing first
deformed and then tore.
The tubing used on the type 2 version has a thicker wall, but
only marginally. And I have more
than a dozen of these new brackets sitting here, although not yet powder
coated. So earlier today I went
over to John’s. We attached one of
the new brackets to a steel plate, mounted the mtb stem and used a 1” piece of
steel tube in the stem as a lever.
We torqued the bracket until it broke. Well it’s definitely stronger than the type 1 version, in
part because of the different design.
But before making another batch of brackets I’ll try torque testing them
with some tubing of different wall thicknesses - about twice as thick as on the
current type 2 brackets. And that
leads me to the executive decision…
The decision:
Even though I realize this slows down delivery on TerraTrike kit orders
even further- I think I’m setting a Guiness anti-speed record, I’m not sending
out kits with brackets if I’m unsure of their strength. Clearly this doesn't do much for my reputation, but trading quality for speed just doesn't make sense. What a way to begin the new year.
That said, I do have about a dozen of the original type 2 adapter
brackets sitting here. They may in fact be plenty strong enough, but honestly I
don’t really know. If anyone would
like to be a tester I’ll gladly give away the brackets for free. They aren’t powder coated, but they
have all the hardware needed.
The new TerraTrike kit, which includes the CURVE neck rest,
“T” tube, mtb stem and adapter bracket, will be $110. If you’d like a kit with one of the original type 2 brackets you can have it for $85, the same price of the Catrike and ICE kits which don’t require the adapter
bracket. If you want one of the
$85 specials and for some reason the bracket doesn't hold up I’ll replace that
bracket with one of the new ones for just $25…free shipping.
If no one wants the type 2’s then I’ll simply pile them next
to other near-great ideas in the shop’s museum.
Might as well end on a glimmer of good news: Here
are the two latest embroidered covers.
The flaming blue trike cover is looking for a home. If you’re interested let me know.
I'll take one of the headrests with the type 2 brackets, Steve. I know you are off for a few more days, but I wanted to get my name in line. This is Wade Lindberg. Thanks, I've sent you an email about it as well. Have a good week off.
