Powder Keg:
Yesterday I worked on my drawings a little. Some of the pieces started in my head and I drew them up a little later on the computer, to figure out angles and hole locations. It's an odd way to go about it but its the way my brain works:o)

Earlier I had started on the rear fork crown. It needed the fork angles milled into it and some short pilots to locate the fork tubes while it's being brazed together. The angle ended up being 8% so I set my angle head with a level in it at 8% and clamped it in my milling machines vise.

I like pictures with chips in them:o) It seems like a lot of guys go to a lot of trouble to clean up everything before the picture is taken? This is machining and it is messy sometimes. At work running the bigger stuff chips go everywhere. Here are the holes to locate the fork tubes.

I then set the angle finder to 16% and leveled up the side I just milled. Flattened everything and poked a couple more holes in the end and this piece is done.

It might need a locator milled into the top so I can weld the frame stem in straight and centered?

Next, Fork ends\o/

Chips in the pictures are a good thing...

Swarf is good....... :thumbup:

This whole project is awesome! :bugeye:

I found a piece of metal to make the fork ends out of. It was a scrap left over from the head pieces. I sawed out what I needed.

I then started squaring up my block.

Once the rough side was cleaned up I flipped it and milled it to length. This piece had a factory edge and it had too big of a radius for what I needed.

I then milled the ends square and cut it in half.

While the piece's were still big I decided to drill the holes I needed. This is the axle hole.

I then had to set the part up in an angle vise to mill the holes that the fork tubes fit into.

Here is where I'm at. I still need to whittle a bit more metal off the fork ends.

I'm pretty excited how these forks are looking. This whole project is a lot of fun for me to work on and think about. I've posted over a hundred pictures now and probably taken 400. Maybe I'll finish this thing after all:o)

Brass_Machine:
It looks very cool.

You better finish!
