# How close can the Maslow4 cut to the edge of a sheet?

If I was to use a Maslow 4 to cut out sheet goods, how close to the edge can I go without it tipping? I’m curious as to what people have done with unsupported edges (just the base sheet you’re cutting from) vs using a strip or other support the same thickness as the base sheet.

Edited to add that I think failures would be just as helpful, if not more so, than successes.

This is something to solve, taking a random lets say for simplicity sake a rectangular workpiece of arbitrarty thickness, and building a telescoping or other reconfigurable perimeter that allows cutting of the complete workpiece. The challenge is accommodating variable thickness workpieces, Z.

I understand the theory. That’s why I’m asking for people experience.

We don’t know. With the earlier versions of the maslow, this was dependent on a
couple of factors.

1. the closer the belts/chains were to being parallel to the workpiece, the less
tippy it would be.

2. the closer the belt/chain attachments on the sled were to the center of mass
of the sled (along the Z axis) the less tippy it would be.

3. if there is too much friction on the bottom of the sled, that can cause it to
want to tip.

with the maslow 4, the 2nd factor can’t be adjusted much due to each belt being
at a different height, but since there are not big weights attached to the sled,
it needs to be adjusted less than on older versions.

We don’t have enough testing to figure out if shifting the anchors from being
anchored at the height of the bottom of the spoil board to being roughly the
same height as they are on the sled makes a significant difference or not.

we do have indications that sled friction can be a problem, waxing the bottom of
the sled, or slippery tape on the bottom can help.

if you are willing to settle for a rectangular workpiece of a known size (say a
full sheet of plywood), then just make L shaped supports that have a slot in
them to allow their height to be adjusted to match the workpiece.

The other option is to make your spoilboard larger than the workpiece and just
attach offcuts or other things the same thickness as the workpiece.

you should not have to support a full half of the sled, on the older versions of
the maslow, even a couple inches off the sides made a huge difference.

@dlang that’s the kind of data I was looking for and I’d a good starting place. Thanks!
