Thank you so much! The knowledge you share is very valuable. Because unfortunately it often happens that professionals are not eager to tell "how-to-do-it-correctly" advice for the younger generation. E.g (wheel speed for carbide cutting) among other things. This great channel makes an exception to that so called a "quiet knowledge" rule! 😊

Im loving these videos. A couple of questions. What is the hand dressing stick you are using for hand shaping and dressing normal wheels? Is the diamond cutoff wheel you used a bonded diamond wheel or plated? It was hard to tell from the video. Would you be able to post details on the wheels you are using? Especially the diamond wheels. That rim wheel for the final shaping looks very useful. I would also be happy to watch the process of your setups and seeing your thought process of how to achieve the various angles and access. Thanks.
@Lappemountainliving 4 күн бұрын
Very happy you're enjoying the videos. Most of my diamond wheels(including the cut off wheel) are either plain or dish style with a bonded diamond usually 100% concentration and between 150-350 grit. I get different width plain style wheels(The one I cut off with is 1/16") and normally get a 1\4" thick layer of diamond on all of them. With the dish style wheels the diamond layer is normally 1\4" x 1\4" I don't show a lot of set up because most people aren't interested and the videos do poorly. Thanks for watching! Cheers and happy grinding!

Thanks. A very good video. I'm trying to think back to my college days, but doesn't the 3 degree back rake on the top of the tool tend to narrow the 60 degree included angle? Form tools don't usually have back rake. Not a criticism, just a question. College was a long time ago.
@Lappemountainliving 4 күн бұрын
Great point and yes you are correct. I did consider this before starting. I measured up the tip of my indexable threading insert (that has a healthy back rake) and found any difference to be so small it was not measurable. Then I did the math on how much effect there would be over the single depth of the small threads I am cutting and again the effect was insignificant. My thinking is I could run the tool tip just above center to help split the difference and at the end of the day I might need an extra tiny bit of depth of cut to get the threads to fit but I feel that is worth the trade off for having a more free cutting form tool. Extra points to you for a great observation though! Thanks for watching! cheers!

I actually was wondering about grinding a screw slotting cutter thinner to fit a smaller slot! I always enjoy your videos! I think if I try thinning a screw slotting cutter that I might not thin it all the way to the arbor in order to retain rigidity, what are your thoughts? Thank you!
@Lappemountainliving 7 күн бұрын
Yes it makes sense to only go part way to the hub/arbor for reasons of rigidity. I would recommend that while you're at it anyhow go far enough to suit any future slitting needs you may have. Cheers!

I forgot to ask, are you grinding right up to the shoulder of the hub of the cutter? I’ve a er40 Morse taper 5 holder to grind the flats slightly smaller to fit my mill and wondering whether to grind right up to the shoulder? And if so should I dress the wheel with a sharp corner to get into the corner? Thanks!
@Lappemountainliving 7 күн бұрын
I did grind right up to the shoulder of the hub. I didn't make any effort to keep the corner of my wheel square. I'm afraid I'm not familiar enough with what you're up against to give much of an opinion. I have noticed that grinding wheels are horrible at keeping a sharp, square edge when forced to work into a corner. It would probably be easier to make the flats longer than you actually need than it would to maintain a sharp inside corner. Again, not sure if this is helpful with your exact circumstance.
@Deebo1812 7 күн бұрын
That makes perfect sense, thanks very much! I’ll make the flats longer and accept the non perfect corner!

How long do you expect the diamond to last? I was shaping a small point (1/2” dia 1/4” wide) it was broken and jagged and I need to true it up. I got pretty significant wear on a new 1 carat diamond. (Cheap eBay diamond). That seems excessive. I am thinking it is just a crappy diamond. It was black in color.

thank you for accepting the challenge. There is no rush at all, every detail counts when learning. I use 6mm end mills on my CNC mill mostly more as a machine safety. 6-8mm tools snap much quicker compared to larger ones, and the machine itself won't suffer or deform when happens. These very good small and thin CNC cutting tools nowadays are expensive too. So, it is worth sharpening them. (Carbide end mills). There are not professionals enough for this complicated sharpening jobs, and not because end mills very chip. They are not chip any more. Thank you once again.
@JohnBloomfield-x1l 14 күн бұрын
Interesting exercise, like your thread grinding setup! Instead of centre drilling the M2 HSS blank, had you thought of grinding a male centre on each end instead and using female centres (easily made) in the cutter grinder?? The male centre can be made as large or small diameter as you need depending on the size of the workpiece.
@Lappemountainliving 14 күн бұрын
I had not thought of doing that. Interesting idea!
@janstaines5989 15 күн бұрын
Is the fact the tap is presented to the grinding wheel at an angle the reason that you get some (most) radial relief and some axial relief? Or it the relief fixture capable of independently varying the two reliefs? Thanks in advance and hope your recovery is smooth!
@Lappemountainliving 15 күн бұрын
The relief fixture can independently vary the axial and radial travels infinitely within it's design range. The angle that the tap is presented to the wheel simply gives the lead in angle, e.g., taper, plug or bottoming. Thanks very much for the well wishes!

Great question. I don't know whether or not KO-Lee offered a drill grinding fixture. I've played around with some micky mouse, stand alone drill grinders and never had much success. I would like to eventually get my hands on a old "proper" stand alone drill grinder. Thanks for watching!

Yes , very good indeed, as good as all the rest of your videos are. I want to see you sharpening/grinding 4-6 mm end mill and drills. Not as an exam..., this seems to me more intricate job and I have to learn doing it. I thought of using a camera. I wonder, you as a professional, what is your way/approach. Is there any other tiny set of tools for this job, or....? I have a good grinding machine here (3E642e universal grinding Russian machine ). Just learning now.
@Lappemountainliving 15 күн бұрын
Challenge accepted! I don't believe I have ever tried sharpening such a small end mill as the cost of them is so low it wouldn't be worth the setup time/cost unless you had a bunch of them to do. However as a challenge and a project I think it would be fun to try. I am not aware of any tiny equipment that would make the sharpening of small end mills easier. Thanks for watching!

I'm a hobby machinist and also have a smithy and like it but you got use it like a smithy, not a bridgeport or engine lathe. I have mine mounted on a harbor freight 72' tool box with a regular kitchen laminate countertop. The tool box wheels were removed and a 4" square metal base installed with leveling legs. For drilling, I'll use a ER 40 x R8 collet and then use ER20 x 6" collet in that. This setup gives me 5" of travel without moving the mill head. The best thing you can make is a solid tool post for turning. It'll seem like you got a bigger machine. I was using the lathe as a mill in this video but you'll get the idea of the solid tool post.
