Machining fin jigs

[Joedang]

The fin jigs (middle and ends) are designed, but need a few things to come into meatspace.

• [x] There needs to be a 2D technical drawing made of the part. (Not strictly necessary, but VERY handy.)
• [X] The aluminum plates must be acquired.
• [X] There needs to be CAM done for the particular machine it will be made on.
• [X] Someone needs to do the actual machining.
  That's Peter.
• [X] A 1/16" cutter must be purchased. (2 flutes strongly preferred)

This part requires a 1/16th inch end mill and is roughly 18 inches square, I think. It's designed as a purely 2D part.

@Joedang I've been shopping cutters and there are no 1/16" cutters that have a 1/4" shank (since my machine only takes 1/4" and 1/2" shanks). The smallest cutter size for a 1/4" shank is 1/8". So we either need to do this on a different machine or re-design the part.

Some of the cutters here, here, and here fit our needs. There's also this listing on ebay, but I'm not sure how well 3 flutes would work with aluminum when it's that small.

Awesome, thanks for finding this. Got the bits ordered, they should show up on Thursday.

Reason for closing: @petermccloud made the thing.
