When I was training in mid 70's, instructor always made a real big deal about working out helix angle. As usual, we 'kids' (18-20) didn't pay enough attention. I had to make a 1" Whitworth thread, helix angle suddenly became 'quite important' as thread depth allowed tool to interfere with sides. Was almost finished when half nuts disengaged, destroyed thread when it took 0.100" cut. (it was a very old worn machine, mainly kept to force people to pay attention, I had previously made 'hundreds' of 0.060"dai, 0.300" long stainless steel rivets for Vic's hobby of clock making ) Vic would go a bit crazy if we ran machine backwards instead of disengaging half nuts, had to use thread dial on all Imperial threads. I've always had a problem with compound angles so trial and error for me as well.😉

I like those shields that you are making for the grinder, and although the wheels very seldom fly apart and put out both of your eyes you are taking all the necessary precautions not only for your own safety but showing the world the right way to do the job, thanks. Thanks for showing how to make a precision thread cutter the right way. And getting your lawn mowed for free, no snakes, no problems, I did see the HBM standing at attention waiting patiently for the year 2024 to come rolling in, so the master can start addressing those ways, and all the broken and bent and missing bits and pieces.

Given the Hercus brand catered mainly to the education sector, that poor old Hercus grinder has probably spent it's entire life making threading tools. I recall making a square threading tool when I was an apprentice on the same machine. What ever happened to Hercus? There used to be a Chinese company making machines and the local importer had them branded as Herless. No doubt trading on the similar name.

100 % agree on grinding wheel guarding, doesn't take much for then to explode, even when used properly, many don't realise the portable hand tool discs are flexible, not so on machine tools, though some slitting wheels can be. 10 & 14" metallurgical sectioning wheels are certainly not flexible .

Hi Max, I have an Ifanger threading tool with 55 and 60 degree HSS inserts, certainly a handy tool for finer threads. I use mainly carbide threading inserts now. Offhand grinding HSS is becoming a lost art with the multitude of inserts available I think. Back in the late sixties used to watch the machinists offhand grind HSS toolforms, true craftsmanship. They wouldnt let anyone near their grinders!

When he said Compound Angle back on the Gib strip video, I started looking up how to do compound angles. I wasn't getting anywhere, so I took a piece of paper & drew the gib strip very large. Then I marked the 0.065 measurement across the top.That is when I noticed I needed a right angle from the inside face of the strip to the 0.065. As soon as I did that, I realised the 0.065 was the hypotenuse of a 30,60,90 triangle. I got all of the numbers Max did w/just regular trig. Now what he showed us on today's video is truly compound angles. I have my Machinery's Handbook marked at that section & plan on trying to learn how it works. Notice I said TRY.

My little KO Lee grinder has a reversing switch, and the washer to hold the wheels has a tab fitting into a keyway on the shaft, I assume that prevents wheel friction from backing out the nut. Reversing the wheel definitely helps with different setups, such as getting to both sides of a cutter in one setup... @@swanvalleymachineshop

Nice trick of angling the tool up in the vice to grind the relief. I use a multi axis vice on mine (home made) so I can set all the angles independently. I never put top rake or back rake on because as far as I understand it changes the geometry of the groove it cuts. I guess you could, but you'd have to do a bunch of 3D trigonometry to get all the angles right.

Could put this vise on a small tilt table, if you had something handy... Also, using a single lip cutter grinder, I had to do the other side of the tool rotated upside down, but better than freehand.. and the workhead gives you the relief angle (although I needed to add another index mark to measure negative - upside down - relief angles). Great to see things coming together! @@swanvalleymachineshop

Great info on tool grinding. If you use a universal grinding fixture and set all the relief and cutting angles at once, would it eliminate the need for the secondary grinding you have done? Thanks again.

The angles still have to be set with a universal fixture . I plan to make a tool block to hold them at the right angles . 👍

Not sure if the tool grinder spindle rotates fast enough for those cutoff disks Max. They tend to like to run over 9,000rpm; I think (with no proof I admit), that if they are running faster, there are internal stresses built up that help the disk to maintain its shape.

@swanvalleymachineshop

9 ай бұрын

Those reinforced cut off disks can run up to 12000 rpm , my spindle runs at 4000 rpm . The lower revs are not the problem but over heating them is . That is why alot of companies have banned the 1mm ones . People push too hard , the wheel gets hot & goes into a saucer shape & breaks apart . 👍

I recently bought the 5.16” Diamond holder from Eccentric Engineering. I haven’t got a chance to try it yet. Reminds me of my old Williams and Armstrong holders. But while I bought sone ETM Super Cobalt pieces, I’d really rather use carbide. But no matter where I go I can’t find 5/16” square carbide. Nice job. But I’m wondering why you needed to make that rather than to use carbide thread inserts? I haven’t ground a threading tool in maybe two decades.
