Brian and Dylan hard at it in the B's in Eugene last week end. As a mechanic, that sand pit is no friend of mine.

Here's Devos front triangle almost fitted. If you look close, you can see the fixture is slightly askew. That's how I sneak up on getting a perfect flush fit on the miters. I have added that third vertical strut so I will be able to hold the top and down tube in place while I tack them as they tend to move due to the heat.
