Re: KR Wilson Groover
does this help any,
The ring with the slot is for setting the cutter to maximum depth |

Re: KR Wilson Groover
You make your own cutter out of some 1/4 high speed steel stock. Most machine tool shop sell. It will need to be shaped using a grinder to match the groove needed.

Re: KR Wilson Groover
It is a very unusual cutter, it just pushes in and must be free to rotate. A spring clip keeps it from falling out.

Re: KR Wilson Groover
Thankyou 1930 Coupe
Seeing the cutter now makes sense. As i have the jigs i may as well use them. the guide channel on mine has been damaged so i will need to repair them first. i assume someone tried to put a standard cutter in it with out the front guide and it took a chunk out of the guide. i will make a drawing of the cutter for future reference. thanks again Rob |

Re: KR Wilson Groover
Interesting because my original cutters did not look like that. I will go down and take a picture when I have a moment.

Thanks Terry.
Easily made made from high speed round stock, probably 5/16? Notice the relief angles on top and sides. Machinist call them form tools and sharpen using a abrasive honing stone. |

Re: KR Wilson Groover
The material that is being cut has to go somewhere. It usually tries to curl up. The one pictured in post #5 doesn't seem to allow for that. I think someone was looking for a way to control the cut somehow but I'm not sure how it would work or if it would even work at all.

I have used it many times and it works great and makes a very nice grove. Are you saying that I need to stop using it and put it in the trash |

Re: KR Wilson Groover
Without going to look at it it im pretty sure mine has a cemented carbide tip. Maybe thats why the odd shape on the one shown

For "ripping" thru soft metal at a snail's pace, what would the advantage of carbide be? I would think it would have been an unnecessary waste of money. Am I missing something?? |

Re: KR Wilson Groover
I am happy and OK, just did not want other people to get confused.
If you tried to hog it through with one heavy cut, then it might do like you said. I take 3 or 4 light cuts and it works great. |

B79A4A35-2674-4B40-B473-B7BE804C80E3.jpeg. Def a brazed on tip and another broken one i found. Figured some tried to salvage a broken on by grinding it like that. Are they home made? Possibly
