Guard milling question.
I've done the search thing, but didn't find the answer I was looking for.
Haven't worked with guards yet, but want to have a go. My question: Can I put a milling bit in the drill press, using "guard sized" scraps, add a guide to the press table and mill out my guard that way? (By using the side of the bit & cutting.) I haven't seen evidence of anyone doing it this way. I assume for a reason???? __________________ "I love fools? experiments. I am always making them."

I use rotary carbide rasps on the mill/drill to shape the guards. Because of the curves and contours I free hand the metal stock versus using hold downs. Even then I have to do alot of hand filing and polishing. I mill out the slot and then use small jewelers files to get the tight tolerances. Many people still drill several small holes and then use a small file to complete the slot. I have screwed up more of them by trying to mill them vs. drilling/filing.

Mark, Before I owned a mill Tried exactly what you are asking and didnt have much success. Thats not to say you cant but I had a difficult time. I think my cheapo drill press had something to do with that. Once that didnt work I went to the drilling and filing and it didnt take too long doing that to know I needed a mill.

The difference between a drill press and a mill is in the kind of bearing the quill rides in. A drill press isn't designed to handle side loads like you'll be putting on it by doing milling operations, whereas a mill is designed to handle those loads. It may be possible, but eventually, you'll wear out your drill press.
For something as small as guards, Harbor Freight has a small micro mill for $299. http://www.harborfreight.com/cpi/cta...emnumber=47158 |

Thanks, guys. A mini mill it shall be. I wondered how much abuse the "side pressure" would put on the press.

I have a sears drill press that is 20 years old and I have been milling slots in guards with it. I use a cross slide vice from harbor freight and end mills to do the cutting. You can't cut it in one pass though. I usually only take about 1/8" at a time. Since I'm using small mills 1/16", 1/8", 5/32", and 3/16", I'm not really putting much of a load on the bearing. I also get excellent results.
One side note: In the future I hope to own one of those mini mills from harbor freight. I'm sure it will be better in the long run. John |

I'm about to buy a mini mill to do the same thing (slot guards). Is is worthwhile getting a slitting saw or are end mills the way to go. The guards I've been buying from K&G appear to be saw cut.

When I first tried milling with a small drill press the side loads kept making my drill chuck fall off. Later, when I got a larger and heavier drill press that problem went away but there is still no comparison between that and an actual mill.
Slotting saws work OK on large mills but they need a lot of rigidity and weight behind them because they don't really seem to cut all that easily (at least mine dont). I'd stay with the end mills. Besides, sooner or later you may want to make a guard for a stick tang knife and that will require an end mill ..... |
