Re: Question to owners and common users of the Skierg

Use it as much as you feel comfortable with. Done properly it will crush you, including the legs!

Re: How to spend my money?

One consideration is that the C does not have a generator which means you will be replacing PM5 batteries much more frequently than on a Model D. I don't have data on how many hours of use you will get from a set of batteries, but it's on the order of a couple hundred hours depending on use patterns...

Check out these two links. Basically the shaft, blade and handle are all subjected to loads greater than they will see in normal use in the field.

Re: Shock cord tension

roughly 4-6 pounds from catch to finish, though really it just needs to be enough to return the handle without a lot of bounce. JonW

Re: model D pickup/generator

We had to change the plastic base and cover to accommodate the dual coil. Call C2 to clarify but I think it's best to order the whole assembly.

Re: New rower, 10k form check

What Lindsay said- 1) you're over compressing the knees at the catch, starting the drive in a weak position. Shins should not go beyond vertical. 2) on the recovery, think "hands away" to get the hands over the knees before bending the knees. This will get you in a stronger, more prepared position f...

Re: SkiErg Model 1 vs 2

The model1 is only for double poling, no single stick/classic skiing. Model 2 can be skied either way.

Re: Different versions of model B?

When I pull on the chain the arms and fly wheel assembly roll to the right quite badly. I don't know if that is normal for a model A/B or something else that needs tweaking. The wooden block seems to add enough stiffness between the left and right arm to dampen the affect significantly. I don't see...

Re: Different versions of model B?

Looks great- I love seeing the older machines still in use. Regarding the issue of the arms pinching the axle, there's a better solution to that. Looking at the 4 large main frame bolts that attach the footplates and arms to the monorail, if you loosen the top forward nut and bolt a bit and tighten ...

Re: Any tips for getting sprockets off the axle?

agree with Carl- grinding is a viable option if you have access to one. Also note that the odds of a new chain functioning correctly on an old sprocket are very remote. JonW

Re: Any tips for getting sprockets off the axle?

Any tips for not breaking the fly wheel cog? or just a case of don't apply too much pressure and more oil and heat?
I assume you mean the cog tool, which is a large hex nut with a one way clutch in it. I guess just more heat cycling and oil. Good luck! JonW

Re: Any tips for getting sprockets off the axle?

It's a right hand thread. Heat and penetrating oil should get it. I've removed dozens of them. JonW
