Tis the Great Grandfather Henry Banton in me - the tendency to at least once throw caution to the wind.
A flycutter mounted into a drill chuck - From the advise by those who know, coupled with the less than desirable racket it makes [racket that means 'Duck for cover'] I can join the univocal and say - Nope - Something going very wrong, very fast is something very well to be avoided . . .

You made me chuckle - Mom still wonders how I have managed all these 64 years - i tell her, without me, she'd have no one to worry about . .

Drill chucks are only just about secure when drilling downwards, to put any side loads on it is asking for the taper joint between chuck and it's spindle mount to let go and the chuck and flycutter is liable to be bouncing around your shop or yourself.

Please take care.

I have to adhere to this advice. This is in the ABC of "what no to do with a milling machine". When machining, things can turn into a disaster in fractions of a second. And damaging your equipment is not the worst that can happen to you. If you are going to walk the CNC road, your tooling should be fail-proof, so using a drill chuck is not the best idea.

Going CNC means that you know almost everything about machining and that you have spent a good momey on apporpiate tooling. CNC is not just throwing some motors to the milling machine and connecting them to a PC. I donīt know any good CNC machinist that is not a good manual machinist.

Just my two cents

Haven't been on in a while. Didn't fall off the face of the earth, just have been crazy buisy with work so haven't had any shop time. Hope that changes soon because the weather is turning cool at the shop is at prime comfort levels. Careful with the flys. I have ruined many a parts from the head moving unexpectedly. If that drill has a morse taper i would use some collets. Better grip and more concentric.

There you are - The fly went to the bottom of the Sound - Only time the taper came loose, ages ago using a forstner bit on pine. Replaced the chuck with a Jacobs No. 36 [it has holding power] and pinned the taper to the shaft.
No rings, No watches, No long hair or sleeves - Don't use a tractor to tension barb wire - It's inevitable to get a little nip here or there - Justt try to keep it 'Little'

Ah the new toy to drive the bride insane - A 23 quart pressure cooker - I like Chili, big pots of Chili - the Pss-Pss-Pss of the steam release, the Bride not so much . . .

Farther away from the grinding wheel my knuckles are, the better I like it . .So as to entertain myself - Won't know the functionality until it's done, any resemblance to what's in the book is - Well have to start somewhere - -

Of course you are free of using your machinery in the way you want, but please, donīt confuse new machinists saying that. Every experienced guy will tell you, using a drill chuck for milling is not a good practice and can be dangerous. But if you prefer investing in steppers rather than in the appropiate equipment, itīs your decission.

Am aware of the downside, I'm just a tinkerer, I tinker - Is not meant to be a mill - Just a tinkering exercise to learn some Arduino and stepper code - Best Practice - First run after a cam change, the thing that can harm me while final tuning is done is not present

Man, I'm having withdrawals from my shop. I've been so busy with work I haven't had time to do anything. Doing a 15 story hospital and a college basketball arena right now, plenty for one person, lol. Might have to make an executive decision and forgo work this weekend and get my priorities straight again. Lol. Love my job but there isn't enough hours in a week to do what I need to do. Three 55+ hrs weeks in a row is starting to grow a little tiring. Kills my motivation because in my head - if I have time to work in the shop I have time that I should be getting ahead on my jobs. Best time of the year temp wise to be in the shop but it seems I'm in a similar situation every year. I need to get my wife a new pressure cooker, hers has a temperamental seal that you have to beat on the edges to get it to seal up, just don't want to end up on some stupid watch list for buying a cooking pot. Lol. Got to finish my mill.....

I change the seal every couple years - - Pressure cooker scares the tinkles out of the Bride so naturally being the kind hearted soul that I am, just had to get a bigger better one - - -

Well I finally got to tool around in the shop some this past week. Good news is I got the mill all moving in the right directions now. I'm stumped trying to figure out tool length offsets with the software side. It should be pulling lengths from my virtual tool library and compensating in the z. So far no Bueno. I made a test part that first faces the part with a 9/16 end mill then does a contour cut around the out side with a 1/4 then bores a hole through then mills a pocket. Part is just complicated enough to run through a few more complicated cuts than facing. Does everything but z after the tool change isn't adjusting...? Guess I need to keep messing with it till I get it worked out. Hoping to do it over the weekend but had to go out of town for a funeral ( wifes grandfather). Once that's solved I have to write some code to adjust for backlash. Not to make it perfect, just to smooth out the enormous amount built into every x2 mill. I think it's something like .072 on z direction changes. Frankly just happy to finally have everything going the direction and distance it's suppose to. Baby steps.
