Day 2 using PoweriSers

[Powergirl.]

Well your doing well from what i've seen here zipp, nice stuff. I really want 7's they look awesome, but i dunno whether to wait until my b-day, and ask for them, or just pay for them myself =/ hmm, i'll have to think about it.

Keep up the good work!

[Pieforce]

Ok,
Here's how the lower joints on my risers look - not at all flush.  Does anyone have a picture of how they should look for comparison?  This is killing me - the sun is shining and I'm making no progress .... Grrrrr.

[Pieforce]

... and here's how the joints on the other leg look

[Bill C.]

There is definitely way too much space in that joint.  Here's the design problem as I see it.  The stainless steel sleeve bushings (as I call them) are fine and good as they stick through the holes of the inner u-frame - however - the design has nothing incorporated into it that prevents the inner u-frame wall from bending inwards except maybe that black plastic bushing cradle (as I call it).  Unfortunately, that black plastic cradle doesn't always extend all the way across and contact the inner u-frame's inner walls.   Look closely at the ends of the black cradle in the above photos.  You can see there is still a gap between it and the inner u-frame wall.  So  any gap will allow the inner u-frame to bend inward and open up that joint to lateral movement. 

Actually, all the manufacturers have to do to keep this from happening is to just make sure that black cradle perfectly fits the space between the inner u-frame walls to prevent the walls from bending inward.  You can see in the close-up photos that the frame of this riser has already bent inward until it has been stopped by the black plastic cradle.  It's just another example of poor manufacturing and/or design.

To further expand upon that bill,
a better solution would simply be to have a spacer (metal) or even a PVC spacer added around the bushing sleeves to prevent the frame from bending inwards.

[Bill C.]

Exactly.  I actually began to write that, but realized that such an approach would require a change in the black plastic bushing cradle in order to accommodate an outer sleeve "spacer.  So I think the simplest way to correct this flaw using the present design is to just make sure the length of that black cradle exactly matches the wall to wall dimension of that u-frame.  That cradle now reaches half-way up the side of the bushings, so it should be able to hold off the inward pressure - if it was the right length.  Higher would be even better.

[Pendragon]

This goes back to my wobble complaint I had a while ago. Mine are the same way.  I threw a washer in that gap.  It helps, but doesn't fix it entirely.  One thing I noticed on my old PoweriZers is that it had a metal spacer thing that kept the hoof frame from bending inwards.  Anyone elses PoweriZer/Flying Jumpers have this support on em?

[Dane]

I want to thank Bill for bringing this issue to our attention. We know that the inconsistent sizing on the plastic spacer/cradle is a problem.  We will have the Poweriser manufacturer resolve this issue so that we can avoid this problem on future sales within a few months.

In the interim please remember your advanced models ARE eligible for warranty coverage, even replacement, for manufacturing defects (including this defect).

You may contact customers@xphub.com directly with photo evidence & proof of purchase or submit a claim through the outlet you bought from, within the USA.

Like the original bearing issue we really appreciate consumer feedback and are grateful to the poweriserpages forum for facilitating this. 

When we have the correct cradle/spacers and/or other problem solving hardware we'll make it freely available to owners of the Poweriser advanced who recieved badly sized cradle/spacers in their models.

Thanks & Best.

[Bill C.]

Nice.  Thanks, Dane.

hi i dont post as much as i used to but i was shown this whilst telling someone about my poweriSers 08s

i have EXACTLY the same problem and have spoken to skate hut and j and r sports and they are picking them up tommorow as i am really unhappy with my 08s as well as having this problem my frame is bent and i mean i can see my hoof sticking out the side of footplate and they should be inline

well i will post pics and stuff and let ya'll know soon whats going on but i deffo think its all 08s as Murdies and Billys are the same the only reason any1 should buy them is if they want to spend £200 on calf cuffs its the only part on mine that still good condition

sorry to rant on but i had to let you all know

Carl

[Pieforce]

Thanks Bill, Dominion, Dane Pendragon et al ... and Carl - mine were from Jand R Sports too and I've sent them an email today to point them towards this thread because they wanted to see some details / pictures. It was exactly as you say with mine - the hoof not in line with the footplate and that lack of alignment throwing me dangerously off balance

[XarnuSonci]

I've developed this in my bocks, but only after a year a of heavy use here's some pics that show the twist better by taking the spring off.
Both of my old ones are twisted like this, the bend is at the joint under the foot plate, the joint at the top of the foot doesn't seem twisted despite what you guys have shown as the bending on that bracket, i've got that too, but no significant twisting there.  I got a new pair, and unfortunately one of the stilts has a similar bend out of the box.

First pic is the old badly twisted frame, the 2nd is the brand new one, only about 10 mins of bocking on it before i confirmed that something was wrong.

[martin]

wow I just found this topic, very technical and detailed discussion, good that Poweriser reacted promtly and offers support

[Green_carl]

well here are my pics of my 08s it took me 6 months to notice and even then it was everyone else in mallorca whilst we was just looking at stilts

u can clearly see the hoof is not inline with the footplate nor thew frame

[zipp]

OK, so a week ago J&R sent out a pair of new bolts for the hoof elbow.

new assembly on the left below, old on the right.


this pic shows the lower alignment problem.



With the new bolt assembly in place on the left stilt below, this is how they look. The new round spacer does not seem to give enough pressure to the spring, and whilst jumping, you can feel the feedback of the spring reverberating in your feet.



At the moment i am using a combo of both bolts (see below) the big spacer seems best, with part of the old bearing spacer inserted. The new copper through washers are certainly a better design, but the rest of it leaves something to be desired. The hoof elbow certainly feels more secure now as i have it set up, but the footplate elbow is also a problem area with wobble, so the problem is still there.
