Did you get the "special package deal" that included the jig to use
with the adjustable height bar which comes with the unit? Says
it lets you sharpen things up to 3" wide.
The WS3000 is a slick little unit which, as you've discovered, is
almost idiot proof for flat backed, single bevel square edges
from 1/4" up to 2+ inches.
Couple of suggestions for you.
1. Make sure you burnish the outside edge of the sanding disks
down really well, and if anything hangs over the edge, burnish
it over the edge. I was sharpening a single bevel knife edge
that required that the edge "face into" the direction of rotation.
Had a teeny-tiny overhang on the paper - which the cutting
edge caught. This little puppy has more torque than I thought
and the resulting "catch" scared the bejeesus out of me.
Loosing control of a sharp edge is not on my Bucket List/
2. Put a couple of "fender washers" (large diameter, small hole
diameter) under the disk to get it up above that lip around
3. READ THE MANUAL
For narrower chisels they suggest using the LEFT side of the
angle jig and for wider edge use the RIGHT side.
I've got "india" and "arkansas" stones, japanese water stones, DMT
diamond plates, a grinder with sharpening jigs (Wolverine), a Tormek
and a JoolTool. For bench chisels and plane irons NONE can compete
with the WS3000 in terms of speed, easy and safety of use.
As you noted, if it's quick and easy to sharpen a chisel or plane
iron - you will when you even think the edge is going or is lost.
With the WS and the 400 grit touch up takes seconds.
When I get the shop cleaned up I'm going to make something to
hold it on my lathe bench - turning tools loose their edges real
fast and continuing to turn with a dulling edge means more
effort and more clean up work.
Now what are you going to do to keep all the paper disks and
wheels organized? Here's one idea (Watch the line wrap)
May The Edge be with you.
