Good show sir, you can’t argue when it works. I dragged an antique tool and cutter grinder home one day for $50, don’t be too impressed though it is far from in good shape. Thank you for sharing.

@@stevohdee8118 rounded or angled will give a stronger corner, especially good for roughing cuts. Keep sharp cornered mills for finishing, if you need to cut a sharp corner. Although it is best to try to avoid an unnecessary sharp corner as in some applications it can become a stress raiser but frankly that is unlikely to be a problem as most home shop stuff is over strength to start with and is unlikely to be over stressed.
Why does it feel like I got taken for a ride by the “no cutter grinder, no problem part” … ? I guess technically he didn’t have a dedicated cutter grinder but i don’t know if having a dedicated grinder post for your lathe classifies as fundamentally different 🤨. But I Enjoyed the show all the same!😅
Very impressive. I'm surprised you were able to obtain such a good surface finish with such a wide cutter on your Mini Mill. My Mini Mill struggles to do face milling with even a 1/2" end mill. Did you do anything to improve your mill's rigidity?
Hey Ian, I have only adjusted the gibs, nothing fancy. I've noticed with milling there's a speed & feed rate that suits certain cutters & a whole lot of info about material. Near the end of the vid on the last pass I slowed down the power feed a 'smidge', which produced a better finish. Fussy little machines. So adjust gibs, experiment, watch lots of machining videos & have fun, cheers mate
I trust you have determined it is not worth the effort/work involved to figure out and execute ....unless of course ....you've all the time in the world and are satisfied with the end result. The actual cutting edge is not "jointed" ....meaning, very likely only one edge is actually providing the finished cut location and finish. This is one reason supporting replaceable inserts. .
You need to test the cutter on the Z axis plunge cutting as thats the cutting points you sharpened . To achieve the same finish just sharpen 1 point and grind small releff on the other points this will turn the cutter into a small fly cuter run fast on alloy with fine feed and you will get a brill finish. also diamond wheel on only Hss cutter is ott . 5 stars for the idear and I love your cutting head.
I wish I had your rig. Just starting out and no dividing head ...no tool post grinder yada yada. Just a mini lathe. BUT I sharpen everything myself. I do it free hand with a dremel tool and diamond wheels. Not the fine stuff like reamers...that requires a different rig but still doable by hand.
Hey traffer, I've hand sharpened milling cutters the same way with fair results. I put the cutter in the drillpress and face the end by pressing down onto a diamond plate then regrind the edges with the side of a 20mm cutoff wheel. Is this what you use? Or a straight shank burr?
@@stevohdee8118 That's a great idea. But nope. I do it freehand with the dremel in one hand and the bit in the other. They don't come out looking very good but with trial and error you can sneak up on having them even and straight. ...mostly 2 flute endmills. I do the 4 flute but they end up looking really bad...but work for some applications.
Nice save on the end mill, is the two piece vice a homemade, or store bought job, Steve?, I've thought about making one for my X2, because I've only seen them down to 6'' wide. Thanks, Scott.
@@stevohdee8118 Awesome, thanks, Steve, I'm in the process of making hold downs for my new screwless vice, woohoo, no more cheapsh!t mill vice, and I can see a homemade two piece in the works.
Your edges would last far longer if you did a 2 angle grind. A 2 to 5 degree "edge clearance", then about 10 more degrees (so 12 to 15) "relief". Get your edge clearance about 3mm wide, then back it with the relief. Puts more "meat" behind the cutting edge, so far more support than your ski slope relief, lol. Yours works, so it's not like "you done it wrong!", but more support equals longer edge life. But, that said, sweet job of improvising a working tool out of a well abused "junk" cutter, using somewhat less than ideal tooling!
Thanks for your info, i never sharpened a milling cutter before so just went for it. Another commenter pointed out that i had the wrong angle at the points so i studied new cutters and went dam, i missed that. So its been a real learning curve, thanks again, cheers
From the final finish shot, it seems like you forgot to angle the front clearance into the centre of the cutter......that is to enable the flutes to cut on the outer edges when you are side milling and keeps the centre of the cutter off the job........this gives the cutter end face a concave effect. I can't give you 10 out of 10 for this as you used an adjustable wrench on a machine.....that is the sign of a hack merchant not a machinist, but I would grudgingly say quite clever overall.
Thanks Ian, I did wonder about that angle, just checked a standard cutter & yes you are right, I will re-cut & see if I can get a better result. As for the spanner I really need to let the moths outa my wallet & buy one or 2, cheers
Do you have a link to the electric motor and ER collet holder that is attached? I have a similar one but the shaft is too small and it deflects a little too much for my liking.
Gday Nicholas, the motor was from a friend that does robotics, "unkermotoren BG42X30" made in Germany. Er16a collet chuck from ebay, they come in various shaft sizes. I've since upgraded tool post grinder, watch my vid TPG 3, the bearings in motor too small for good results, hope this helps, cheers
Well Gordon, thanks for such a technical question. Smidging is the universal term for minute adjustments regardless of one's region in the world. It is an acquired & required instinct for anyone playing with machinery, there is a fine line between yippee & grrr. Over Smidging will produce the grrr so I recommend sneak Smidging. You can always under smidge but over smidge @ your peril... Cheers haha
@@stevohdee8118 Thank you for that in-depth response. You have established a cultural bridge between machinists in England and the US. However, we are jealous of your beautiful freehand scribing!
@@gangleweed thanks Ian, just googled it, a smidge is the informal term for smidgen, which is spelt without the 'o'... Who knew? I've been calling it a smidge forever, may be an aussie thing but you are correct, haha cheers

Ive done 3 vids on home made units, the first 2 show what doesnt work, "TPG 3 third time lucky" is a solid unit that works well. I suggest a high torque variable speed motor coupled to a substantial bearing block is the best solution, best of luck, cheers

Good job.
Your lathe, with the indexing attachement and the toolpost mounted spindle, makes a decent approximation of a cutter grinder....
Thanks foggy
Quite tidy indeed!

Very creative.
I might have been tempted to grind an angled corner rather than a sharp one, for strength and finish, but you did good.

you don't need a diamond cutter as it was HSS he was grinding. Diamond wheels can be used on hss but usually for Carbide!
