Carb-Tech 24 pc Forstner Bit Set?
Hey guys, my neighbor is selling a 16 pc & 8 pc Forstner bit sets. I googled them and don't get anything about the quality of that brand. Anybody ever heard of this brand? He's asking $60 for all 24 pieces. Two sets (16 & 8), each in a nice box with dove tailed corners. Don't appear damaged, all have plastic blade guards that are very tight (? not removed much).
Also has this 3.5 HP Craftsman Routher ($50) and a 6ft Craftsman Turning Lath ($150).
I worry about parts availability. Any thoughts.

When I first had the idea I thought it was going to be really simple but then I found out that all three sets of Forstners I have have metric sized shanks and I don't have a set of metric sized bits but it was a fairly quick work around to solve that. I used 3/4" ply and the ply is thicker than the Forstner rim is high and that is a requirement for making the jig. The bit I made the jig for has a 15mm shaft which is slightly smaller than 5/8" so I drilled a 5/8" hole through one thickness of the ply and then took it over to the cut off saw and roughly cut it through the middle of the hole. Then I drilled another piece of the ply with the bit I made the jig for. (Not sure what size it was, I never looked). With bit still in the DP and lowered into the hole it made I used some hot melt glue to stick the two other pieces of ply tight against the bit shaft. All that's left to do is clamp it in place. If you need a precise location then dimple the spot where it needs to go and you'll be able to feel when it's in place. The hole I drilled is as far as it would go without removing the jig and getting rid of the chips but it's no issue to relocate the jig to the same spot to drill deeper. The pictures tell the rest of the story.

Could someone please explain to me why a jig is needed when using a Forstner style bit.

In my early post I forgot to mention that a few years ago I bought this set of sawtooth Forstner style bits off Ebay, I can't remember what they cost but I do remember that it was cheap! Unlike the much earlier smaller set from Carbar-tec which were hopeless, these work extremely well but even so if I have a Carbide tipped one of the same size required, then that is what I use.

For a jig, I simply cut a hole in a piece of 2x material (on the drill press) that I could clamp in place. Might not work for every situation, but it did help guide the bit.
Note: Check out the picture. I was repairing a goof up.:surprise: I had lost focus and pulled the router out of the hole while it was running, and before retracting the plunge! It quickly tore up the hole and broke the bit. :frown:
The repair worked great.
