Re: [4x6bandsaw] Re: Vertical Cutting Misalignment
- Hi Glen,
Thanks for making the measurements and passing them along. It is
fortunate that your machine is doing so well, especially after use by
The world certainly needs more just-for-grins activities, and you
have done your part.

- Hi John,
Thanks for making the measurements and posting them.
I am working on a fix and will post results as they are available.
