Semi precision grinding.
Need shallow grooves in wood, *lots* of shallow grooves in lots of wood. At
least 48 in each side of dozens of 16 X 24" pieces of plywood and almost as many boards grooved on only one side. Remote possibility this will become a recurring need and I will be able to afford machinery and or custom tooling to make this easy. For now I'm doing a limited run of prototypes and could resort to cutting them one by one with a circular saw. Perhaps even two at a time with two blades in a table saw. But where is the fun in that? Have access to an old 6" jointer and think modifying the knives with a series of flats leaving a row of cutting tips spaced approximately 1/2" apart *might* just work. Cutting at least 12 grooves in one pass. Looking for ideas that are better than just goobering up a set of jointer knives with a hand held abrasive blade. Have no free access to a surface grinder or any machine shop equipment more sophisticated than a worn out drill-mill combo. BTW these grooves need to be slightly rough. While I want to avoid splinters extremely smooth groves are not what I need or want. Nor do I want any radius at the top or bottom of the grooves. This would defeat the whole purpose of having grooves for the bats little toenails to grip -- William |
