<p>Plywood or hardboard makes a much better base because it is stable. A 1x12 is very likley to bow or warp over time, leaving your saw guide inaccurate.</p>

Dumb question. Why don't most people use a 1x12 instead of plywood as base. Is it a matter of cost? Just curious.

<p>Personally, I've found a 4'' wide birch plywood guide to be less likely to distort.</p>
<p>6" wide stock is even better.</p>
<p>Store ''FLAT'', (horizontal), when not in use.</p>

<p>Yes, is the simple answer. Attach your straight 1x3 to the crooked plywood insuring that the distance from the 1x3 to the edge of the plywood is greater than your circ saw width (distance from base edge to blade). That way when you make the first cut your saw will be guided by the 1x3 and trim the plywood straight. after that you can use it as a rip guide, just align the edge of the plywood to your layout line, clamp in place and saw away.

Yes, I understand. I will get it done this weekend and report back. I have a 1x3 straight high quality piece of wood, and was wondering if I could use this as guide to attach to plywood?
