About 6-8 months ago I posted on adjustable groover cutterheads for my shaper. I have not had funds to purchase anything yet. The other day I read on a thread about having a dado set bored for a shaper. I went online and discovered that ridge carbide has several different diameter sets of stacking dados as well as numerous bore diameters. I looked at a 6 inch diameter set with 1 1/4'' bore available in the 250 dollar range. This is considerably cheaper than adjustable groovers especially as several would be needed to have the same thickness range as the dado set. Am I missing something here ? What are the advantages or disadvantages either way ?Thanks in advance for helping to further educate me on shaper tooling.
