Lash it together.

It feels like a while since I made any real progress on the bike, despite having done regular bits and bobs to it over the last few weeks. Today I managed to shape the top stay set.

The two roughly shaped stay sets.

 The way that they have come together after the redesign for the drop out fitting. Now that the stays are roughly shaped, the really tricky bit lies ahead, fitting them to the frame so that they end up square and my wheel runs true. So I fixed them to the frame with tape to see how they will sit.

I was very pleased that they do actually meet pretty much where I had hoped they would. Of course using tape is not a real  guide. The next step in the build is to cut the excesses down on the end of the stays so they are square. Then do the same in the frame and see how it sits then. I have a feeling that I may need to add another section of ply in the bottom bracket join, as I may have cut too much away. Not sure yet.

Once the stays are fitting well it will be a case of tacking them in with wood screws and measure up and make the metal drop outs. Once those work I can do the final shaping and sanding then fitting. Once together that is it, no undoing it. I liked the way it looked so much I propped a wheel up in the frame, and y'know what? It started to look like a bike. I also took the opportunity to see how the drop out might place.

Glue it together.

       I did the first big epoxy bond of the main frame. Judging the correct amount of epoxy to mix up was a pure guess really, and in the end I got it right, just. There was only a teaspoon full left over. It was great to see it come together and to take the clamps off and feel it as one piece at last.

       While the frame was going off, I took the opportunity to start shaping the stays.I cut a section of the 22mm tubing to fit the end of the stay to. It needed a lot of thinning down, more than I had really appreciated, but the end result looks fine and with a bit more attention will come together nicely.  

 Unshaped (before) and shaped (after).

        Just got to match the second stay to the first, and then fit to the frame for the measuring, making and fitting of the drop outs. I also have to true up the sections of the frame where the stays meet the main frame so that they fit squarely.

Final off the shelf parts.

The order from Ceeway came in this week. Some great stainless steel dropout blanks and stainless faces to be braised on. Also the 22mm cromolly tube that the drop out will be welded to and the wooden rear stays will slot into. All I have to do now is shape the wood to fit, then braise the joints together. Ha, simples!

Drop-out blanks, faces and 22mm tube.

So now I have all the bits I need to complete. I just have to find the time to make it happen. Just as before I will be stealing an hour here and there between work and family. I really want to get this finished by my original target, August. I think that is achievable. 

Also thanks to everyone who is giving helpful comments and advice via twitter and this blog. Much appreciated.
