Still looking for things to do....

Recently doing repairs on a few antique fly reels I found that are very hard to find. I decided to make some screws. Cutting the threads was straight forward; I used the appropriate die. But the cut neat straight slits was a bit more of a challenge as I wanted to use a slitting saw to make positive need slits. Only problem was that I didn't have the saw or arbor and I even needed a collet block.

First things first. I decided to make an arbor. Here's how I did it.

turned down some 4140 steel to 5/8" for the shaft to fit a 5C collet as I wanted to hold it in a collet in the spindle.

After that I turned it around holding it in the 5/8 collet to continue on the other end this ensured I could keep it reasonably concentric as I proceeded

After drilling and turning down the cap piece to .0005 smaller to allow the saw blade to slide on I parted off the cap piece and bored out the body to accept the cap internal arbor tapping the body with and M8 thread and counter bore the cap for the cap screw.

Little bit of a taper on the back of the body and a polish up made a good result.

Now to cut some screw heads which were held in a 5C collet in a holder in the milling attachment on the Hercus

The slits are a little deep here but now I dial in the right depth.

The screws were for a reel that is a good 80 years old - JW Young of England.
