Stainless Slotted Washers

[billsy]

Guys can anyone help me with this? I'm trying to find a more local source for these Stainless washers to go behind my dropouts. I can't find them anywhere other than ebikekit.com which will be $20 just for shipping to the UK. All the ones I have are way too thick and result in excessive spreading of the dropouts. Someone must be selling these in the UK!

Your help is much appreciated.

Thanks

Sorry I can't help much. I buy them at Ebike.ca, maybe shipping in UK is cheaper from there. I guess there must be some source in EU.

Any idea how thick they are? In mm please...

Perhaps file down the ones you have? If you have the patience, you could even just sit on a sidewalk curb and rub them on the concrete, until they are the right thickness. It's tiring, but I've done that with things that I couldn't file down for one reason or another.

I don't know of any suitable substitute. Most stuff I see in the hardware store is too malleable to be cut into a similar washer. It's really a specialty washer, to have so much stiffness for the thickness. Shaving down regular spacer washers won't be strong enough. Getting some custom cut from strong thin steel would likely cost just as much. But if you can source some similar steel, there is always the drill and file method.

But let's look at this another way, are your axles long enough to simply cut the shoulders of the axle deeper, allowing the use of regular thick spacer washers? That should work on a 9c motor. Axles cut easy with a hacksaw. For my alloy suspension fork front motor install, I had to cut the axles the thickness of the washers deeper anyway. Bent out even the 1 mm on each side was binding the fork.

Assuming you are about to mount a motor to some alloy suspension forks, isn't twenty bucks a pretty small price to pay compared to a nice set of forks? Again, assuming you want to use a good fork.

You could buy fifty. Same shipping, I'd bet.

Then offer them to UK ebikers to recover your costs.

They're about 1.5 to 2mm thick, I'll have a look at the one's on my Marin when I get home.

The 9C kit I'm installing was purchased from ebikes.ca. Its exactly the same kit I bought for the Marin and that arrived with two of these washers. I have emailed Justin and Adam to see what's going on.

Yes I have considered the drilling and filing approach, if I can find some suitable steel that is. Also, yes the axles are long enough to cut back the shoulders I might end up doing that. The motor is going on the rear of another Rift Zone (see sig) so alloy drop outs.

TylerDurden
May even be worth getting a batch laser cut from a sheet and sell some on here, another good suggestion. Lets see if Justin has some that he can send over the pond first.

Thanks for your help guys.

You can likely get away with bending out the frame then, by that distance. 3 mm is not such a big ajdustment. Just do it very slow and carefully. Front forks are where you really can't adjust the width of the dropout one bit.

The washers I've got now will require more stretching than that mate, they're pretty fat. With the thinner washers it'll be a few mm stretch so I agree that won't be a problem. Fingers crossed Justin can dig out a couple for me
