Kips sub shaft o-ring

[jamiethegiraffe]

I dont see HNBR available as option for X-rings from Mcmaster. Just silicone, Buna, and Viton.
So i guess Viton? That's the part number Kawibunga lists in that quote

[Chuck78]

That sounds good to me! I'll pay 55% of that or whatever is best to round up to if you will receive the order and ship me 10 of them... Kawibunga perhaps could use some as well as SlickNick, although I believe Nick is in Canada? It might be best for him to source them up there.

[Kawibunga]

Yeah, from McMaster - I'd go with Viton as first choice, Buna a second as that's all they have, they don't have HNBR, But my guess is BUNA will work fine.

And in Canada you need a corporate account to order from McMaster - but we got one so I had ordered my supply on a work order, so I have a bunch of spares if slicknick wants to try them out, a yeah he's located here in Calgary too, so would not a be a problem at all to sort that out. Hoping to have the modified parts in hand on Wednesday this week.....

Oh, goody! Photos please.

Order placed for 50 Viton X rings. Chuck, I still have your mailing address from our email exchange about the 5x8 silicone o-rings. I'll put a dozen of the X-rings in an envelope and post 'em over to ya asap.
If anyone else in the states wants a few, just drop me a line and we'll work it out.

Couple more days, he machined my fork parts, but forgot to do the KIPS shaft. Hopefully early next week........ will keep everyone posted!

Curious how you make out here. I brought the shaft to my machinist and he said it was so hard that he didn’t think he would be able to cut it without potentially breaking the cutter and ruining the piece. We are considering a lathe-based grinding operation with a dremel instead…

He thinks he can do it with a good carbide cutter but will keep you posted........

I had not considered the hardness of the shaft!
I'll have to look for a real small carbide cutter, as most of what I have is tool steel or too large for that tiny cut.


I wonder how deep the hardened surface treatment goes in these parts? That's another thing I had not considered.

[Kawibunga]

It's the Easter Miracle, that Jesus dude came back!........... actually no, just kidding, all though that did happen and is pretty cool, I did finally get all my parts and and am more than satisfied, looks perfect to me. Came out exactly as hoped. Now do get the engine back together.......... Pics below...........

The shaft was hardened for sure, but my machinist said not a problem with proper tools. Your tool steel cutter won't do it though, need carbide.

New cut groove with and without 008 Xring

Measurements........

It's real pain to get an accurate measurement of the new OD with the x-ring on. This was more so by feeling the friction of it touching. A bit of a squeeze and it might read .318 or so.......... but am happy with this, and based on my previous measurements I see no reason why this won't work perfectly......

Apologies it took so long, when you got a guy dong it for free, in the evenings, and I'm not pushing him as it's snowing outside right now so I ain't riding, it took a bit of time.......

[jamiethegiraffe]

Hell yeah! Nice work Kawi! Thanks for sharing with us. The info about being able to cut the shaft with a good carbide insert is much appreciated.
I’ll let my machinist know you had success and hopefully will have one just like yours before long.

Jamie, if you get a chance to take a photo of the carbide cutter setup that you have your machinist use to cut this, that'd be much appreciated. I am not a machinist, but rather a DIY'er who happens to have acquired an old manual lathe and 2 milling machines for home shop fabrication use, therefore my tool bit selection and knowledge is limited in these realms, but always improving through every little project such as this... Same with you, Kawibunga, if you know what tool bit/holder type setup your guy used for the tiny groove. I'll figure it out on my own, but also having a professional reference always helps in my learning process.
