I just found out that the drill press table I made last week to include a vac channel for sanding is almost useless.
Last weekend while making the table I routed a 1/4 recess for hardboard inserts... I thought I made a mistake when the hardboard sank lower than the top...I didn't understand how that happened. But I figured I had a brain fart. I went and bought a new board of hardboard 2 days ago and today I find out not all hardboard is 1/4". Of three different samples only 1 is actually 1/4" The measurements are: .196 = 5mm .225 .250 So even though they are all marked 1/4 they aren't. So to fix my sunken plate I glued formica inserts into the routed channel to raise it. Now I cut a true .225 plate and it is too high... Wish I known b4 I fixed a problem that wasn't really broken in the first place. Now I have to re-route the formica out.
