2-piece seatstays?

[suhacycles]

Greetings fellas,

Got a seatstay issue to ask about. I've got one of those seat lugs with the 14mm seatstay ports (kinda like the ones Zank likes to use) but I want to use a larger diameter seatstay like a 16mm. I thought about cutting shorter sections off the 14mm stays to fit into the ports and then sliding 16mm stays over those and brazing them in place, essentially making them 2-piece seatstays with the joint maybe 20-30mm away from the ports. So I'm wondering:

1) How much of an overlap between the two sections would be advisable?
2) Braze the two pieces together first and then the dropout+port ends or ends first and then the sleeve part?
3) If the fit is a little loose, is using 45 silver or Fillet Pro ok?

Thanks,
Hansen

Could you cut the sockets off and fillet the stays to the lug?

Interesting... well, I guess I could! Any specifics or a visual? I'm imagining it looking kinda butchered... oh, the seat lug is already brazed in btw.

I don't know what lug you are using so I can't tell you what it would look like. I've used seat lugs with stay sockets and I always lop the bastards off and fillet them. Cleaner and no worries about fit or angle.

Dave - I see what you mean. I know the ones you're referring to. The one I have is the 'P23' listed under the 'Other Oversize Cast Seat Lugs' section:

Those sockets don't look that easy to lop off...

Doc?
That is possible and everything, hope it works out and you don't mind the extra wotk.
Now if it was me I would figure out how to flush it (French) it so it all looks smooth.
Filler if you just put a short overlap 12-13 mm is more than enough if you are going to hide it and french it in to look like one piece.
If it is a bit loose you named the best fillers for that to make it simple.

Lot of work? but if you make it nice, I guess it will be worth it. 20-30 mm down from the port I take issue with however?

Dave Kirk is like me a bit, I really don't feel warm and fuzzy over the sockets but on that model you are so right, chopping that up is really too much work for me ?

I wish you Luck with it !

With that seat lug it does look like you are stuck using the sockets.
