Knife Sharpening / Re: Goniometer - MASTER
Last post by tgbto - January 15, 2026, 08:52:11 AMRich, this is a very nice and useful piece of work. Thanks a lot for sharing !
I was wondering, are you familiar with heat set inserts ? They are inexpensive and make for a very easy way to add strong threads to 3D-printed parts. All you have to do is :
- change the diameter of the hole to the appropriate one for the thread size (3.8 mm for a M3 insert for instance, and some even go as far as making a conical insert to minimize bulgin around the insertion point)
- put these holes inside a cylinder-shaped modifier so that the wall thickness around the insert is about 80% of the thread size (3.2mm at least for M4 for instance),
- add them using a soldering iron (any will do but using the included toolheads will make it even easier).
A nice trick is to put them on the backside if you can so that the screw tends to pull the insert into the 3D printed part instead of ripping it out. You can add the modifiers as separate bodies in F3D so they will be appropriately placed in your slicer. I can make the modification for you in your design if you wish.
Many thanks,
Nick.

Knife Sharpening / Re: Sharpen workflow for ‘mid-...
Last post by Royale - January 13, 2026, 04:20:01 PMI think a good place to start is to be very clear on the standard(s) that you're aiming for, and the general trend in knives you receive.
About 99% of customer knives I receive are the end product of numerous botched sharpening attempts, and hatchet jobs by other sharpening businesses.
I just reprofile all knives I get with the SG-250, sharpen with the DF-250, then strop. BESS testing is only for my top tier service (for high end knives and/or professional chefs), and for this service I go through all diamond grindstones, the SJ-250, and strop.
But my motivation may be different from yours, because my business is still relatively new, and I'm more focused on social media outreach and generating customer to customer chatter.
But yeah, I'd recommend establishing what "good enough" is, to be very clear about it, then the workflow will pretty much create itself.

General Tormek Questions / Re: chisel with 25 degrees in ...
Last post by MikeK - January 13, 2026, 03:01:04 PMQuote from: John Hancock Sr on January 13, 2026, 09:45:08 AMOnce you set the bar height for the first one make a note of the protrusion and set them all with the same protrusion.That's what I do and how I was taught by the late David Charlesworth. I have the Tormek T8 (David had the T7) with the DC-250 diamond wheel and SE-77 jig. The bar is 9mm above the wheel and the projection is 38mm for a 25-degree hollow ground bevel.
I use a 5mm and 4mm Domino tenon glued together for the 9mm spacer to set the bar height. This works for all chisels and plane irons and has never failed to produce consistent results.

General Tormek Questions / Re: Jig collar bumps leg of su...
Last post by BPalv - January 13, 2026, 01:15:00 AMIn looking close, the issue is mostly caused by the design of the KJ-45. In the standard jig the collar is flat. On the KJ-45 it flares out slightly. As Sir Amwell mentioned, a file solved his issue. I think a little work on the threads at the top of the leg should solve my issue as well.
Thank you!
And for what it's worth, I think the 430 as the standard makes sense... to me, a knife sharpener.

Last post by John_B - January 12, 2026, 06:35:23 PMI was one of the early owners of the US-430 and it is always mounted for sharpening. I use the standard support bar on the honing side. Saves a little time especially if I am sharpening knives and if I am able to maintain a constant projection.

Last post by tgbto - January 12, 2026, 11:08:20 AMQuote from: Sir Amwell on January 11, 2026, 01:06:37 AMIf sub 200 Bess is your goal then sell out and do all your sharpening on belt grinders and go for volume rather than quality.
I found that controlled angle grinding on a belt grinder followed by controlled honing on leather belt+PA70 compound yield 120ish BESS results. I don't think speed and quality are exclusive, and when reprofiling in involved, this is clearly the way to go. The Tormek has an edge in dust generation and "zen" power, plus it shines when it is not exclusively used for sharpening knives.
