The plugs on the dropout don't fit into the chainstay. The obvious solution seems to be cutting the tapered end of the chainstay until the plug fits, but I'm not sure excactly how they set up the butts on it. Anyone know how quickly it thins?
The chain stay thickens because it it swaged down to 12.5 mm. So it starts thinning as it tapers out. That said, you'll be fine trimming till it fits as you won't have to cut much. You can file the plug a little too.
Your real issue is going to be the angle between the cs and ss. Those dropouts would be good for a bmx bike, I think nova sells another pair better suited to a full sized frame.
I have put dropouts in the lathe to cut them down when I couldn't trim the taper the way I wanted. Usually you can trim the taper though
Just took the metal lathe class, really looking forward to any excuse to play with it!
One remaining question: I just did a pair of these and found that the inside of the plugs for both chain and seat stays had some curves. I had to do some mitering to get the tube all of the way in. I've seen some references to just cutting the tube even and putting it in as far as it will go. Am I using a different dropout, are they wrong, or is it unnecessary to have the stay go 100% of the way in?
