sourcing set up blocks for oldham viper lock miter bit

[tom coleman]

I have a boxed set of Oldham Viper bits including lock miter, glue joint and drawer lock bits.
Never used bought them years ago. Can I order set up blocks for these bits

You can make your own. That's what I did.
You need a different set up block for each material thickness you work with. Note that the setup block need not be the thickness of the stock it is set up to run.

Another reason I'd not want to spend any money on them would be that the Oldham Viper bits I've had did not last very long. The lock miter bit has not been an exception.
