double skip, or multi skip tooth chain. It is consequently easier to push, faster at cutting, uses less fuel, is less likely to burn your bar, and has a longer chain life.

If you already own a large frame and you are wanting to produce slabs commercially, the whole frame can sit on the other end of your existing sawmill tracks, (which may be extended); so that you can quickly change from dimensional sawing to slabbing and back on the same log.

The Automatic Feed Option
The DWS can be upgraded to an automated slabbing machine when fit in the ASM track set-up.  All you will need to do, is use the control panel and drive lever to make your adjustments and cut, then remove the slab once the powerful bar has ripped through your log.  Upgrading to automation with the DWS is the most efficient way of getting accurate valuable slabs with minimal effort.
