Rock Solid hobie pedal arm upgrade group buy .... UPDATED WITH ORDER INFO!!!

2 pairs please

Do you mean a second production run or a different design?

I was referring to additional production runs in case we wanted to buy in the future, but I imagine you'll get more ideas with customer feedback and might consider a design change. In a previous thread I said that the hole that size in the middle of a pedal arm is a terrible design. I would like to see a pedal arm without a hole in the middle. That's more of a pedal adjustment issue than pedal arm issue, so it's probably out of scope here.

In for a pair.

I have a question for the engineers of nwka.  Is it possible the drive arms are designed to be a weak point, absorbing damage that would otherwise damage the drive well?

Count me in for a pair.

Actually, I think that could easily be remedied if the design incorporated a U bolt that went around the pedal arm instead of through it.

Bill, didn't your original repair use a U bolt?

Yes, I used a U-bolt to do an emergency fix in camp. This is definitely an option though it does not allow for the full range of adjustment built into the arm. I believe that the reason arms are failing is that the metal quality is just standard aluminum and not high strength bar. By going to a solid bar an the highest quality aluminum I am confident that we can eliminate arm breakage.

We will definitely be running later productions, though the cost will be higher.

I love billet machined stuff........count me in for a pair too

Any progress or news on this?...if you have a cost I'm ready to send you some $$

I'm pretty stoked about it since I've broken two this season alone.

I have been told that I will have set up cost by end of day today. Hope to have PayPal and everything lined up by Friday to start accepting payment and confirming orders.

Sweet!!

Awesome!!

I have a question for the engineers of nwka.  Is it possible the drive arms are designed to be a weak point, absorbing damage that would otherwise damage the drive well?

I have wondered the same thing. I've also wondered this: Since the maximum amount of force that can be applied to the pedal is whatever the water resistance is at the fin plus whatever resistance is on the other pedal, are the arms breaking more easily than expected because of the natural tendency to not lift your non-drive leg? I.e. you're pushing the fin, plus you're pushing your other leg up, and possibly you're even exerting force without thinking about it with the non-drive leg.

I think this is a cool product, I'm not down on it at all, but I'm curious why the arms are breaking in the first place. It seems to me that if I take one of my feet off the pedals altogether and push as hard as I can with just one leg that I would never break the arm. But perhaps that is not true in some conditions. I'm not playing down the breakage others have experienced at all, but I'm curious if it is relatively easy to avoid.

I'd have to be able to look at the fractured face to be able to tell, but I think these are fatigue failures, not single overload failures.  If it is fatigue then beefing up the arms will only help overall drive durability.  If it's single overload failures then yes, beefing them up could cause a more expensive failure elsewhere in the drive, though that is far from certain.

Good point, fatigue vs. overload.

I guess call me a "strong maybe" for 2 sets.
