I am working on a fairly elaborate box design and finessed all the measurements making adjustments to thick PG draftboard. Then when I went to make the “real” box out of thick PG plywood, I discovered that the “thick” PG draftboard is actually a completely different thickness than the “thick” PG ply…

Guess I never thought of it that way. To me draftboard is a material for testing designs, but I never expected it to be the exact same thickness as Medium Plywood. There are differences between the various plywood types, too. When making boxes or anything else that needs to “fit,” I measure ever…

i never really thought of draftboard as testing for designs. it’s just a different medium for someone who doesn’t need a finished wood product like hardwood or plywood. it’s basically a version of MDF, the same stuff (i believe) that’s in the core of the plywood products. if i do testing, i general…

You’re going to find that materials change thickness even between vendors or batches from the same vendor. The PG materials tend to be more consistent, but there have been variations over time there, too. As well, kerf behavior can change between materials, too. I.e. a relatively soft material m…

Whether people have thought about using draftboard to mock up designs or not… I’d say that this is right in the description of the material: Its thickness matches Proofgrade hardwoods and plywoods, so you can run a trial print to work out the kinks and ensure hinges or other joinery fits flawlessl…

+1 to the variations between batches of even the same material. I have run the same design on different batches of the “same exact” medium proofgrade maple, and had perfect fits become too loose or too thick because I didn’t bother to measure the specific piece I was going to use. If you’re relying …

The way I work around slight variations in thickness is the use of @Dan ’s Teeth in the design. Give them a try, they work wonders. [image] Serrated tabs - no more glue Free Laser Designs I love design but I don’t much care for assembly. Why should you have to deal with …

Draftboard is great for “rough drafts”. It’s particularly handy that medium Draftboard and medium Proofgrade plywood are usually the same thickness, to a few thousandths of an inch. But thick Proofgrade plywood has a lower tolerance so it will vary more. One nice trick about the teeth is that you…

The point of draftboard?
