I am really liking your content. Very meticulous and informative but also interesting and humbling. You have a really captivating voice with a intriguing accent. I mean, it’s like I’ve heard it before or even someone I know. . Hopefully you get what I’m trying to say and I really hope I didn’t offend anyone. Have a good day.

When I need to apply a light coat of oil on something I use a shaving brush to apply and spread the oil. Gives an even smooth even coating. Works very well on firearms also.

In case you haven’t seen it, FIREBALL Tools made a video on back dragging a file. It’s pretty cool and would help with any criticism on back dragging a file. Great video and I enjoyed the Bubba clip for humor.

Thanks!

Nice work Yuchol! You sound a little down in the dumps. Not as chipper as usual. Working in the shop is my drug of choice. Lol. Good times. Cheers!

Heat treating is more of a science than I thought. I often hear it spoken of in relation to knife steels and manufacturers getting it right. Seems to be quit a process to get the Rockwell number up high as that is what a lot of knife collectors want. Thanks for sharing.

Thank you.

This is the first notification of a video of yours I have had in a very long time, I've checked and the notification bell is ticked. Don't know why I've not had them, but hey it's nice to see you again! Nice job Yuchol, the finish turned out very nice indeed! That's one of Stan's heat treating ovens isn't it? They're a very nice bit of kit. I've just made a new nut for my lathe and unfortunately the diameter was only 20 mm so I couldn't use that style of boring bar. I had to buy a 150 mm length of 10x10 HSS and grind up my 29 degree tool by hand to do it. I also made a tap to finish it to size as it was easier to grind the outside 29 degree cutter by hand than the inside. You are able with your set up to set the helix angle without having to grind it into the cutter, meaning if at any time you wanted to make a right handed thread of the same size you nay have to turn the HSS cutter to the opposite helix angle. It's nice cutting left hand threads because you cut from the headstock end outwards and there's no chance of a crash lol. Looking forward to you doing your nut! Cheers from the UK

[@f.hababorbitz]

At the end of your video, you show the limitation of that tool and cutter grinder with not being able to flip the grinding face. I now know why I just saw a video on that subject. They were buying the grinding tool head that's sold without the rest of the grinder, it's from the 25mm feed bar on up. Other comments said to make it so it could be moved to the other side of the grinding wheel. That would require running the grinder in reverse, but seems that would overcome one of the limits. I've looked into getting a cheap Deckle knockoff, but the size of the collets limits the endmill diameter of the shank. I've now seen 5C collet change out accessories. That tempering step is important, I thought I could get away with a draw bar heat treat, and skip that step, it broke off when I was tightening it. I'm the same sort as you and repair and make stuff. Enjoy your channel.

[@woodscreekworkshop9939]

Yeah, I just have to remember what the grinder is intended for. That why we have multiple grinders.😁

[@wmcrash]

I think you are quite conservative with those limit temperatures for the two flavors of stainless foil. Also this video reminds me of the Guist brothers on Swamp People: catch the bait, to catch a bigger bait, to catch a bigger bait, to catch a fish. Tools look good.

[@woodscreekworkshop9939]

Having a machine shop means making more tools for other tools you have.😄. The temperature ratings are specified by the manufactures, not my opinion and are for "corrosion resistrance", whatever that means. The foils would survive at far above temperatures physically. Thanks!

[@grntitan1]

At least you had on your safety squints. 😊

[@woodscreekworkshop9939]

I don't have a choice, it's built in.

[@MyLilMule]

Nicely made tools. I noticed a knee mill, partially disassembled, behind the heat treat oven. Is that something new that we're not supposed to know about yet?

[@woodscreekworkshop9939]

That is my 5 year old project that I need to pick back up.

Hi, do you know the RAL code of the color from your grinding machine 15:50 ?

[@woodscreekworkshop9939]

Unfortunately I don't. It was just a rattle can. Smoke gray I think.

[@37yearsofanythingisenough39]

You might want to think twice about using that keyless chuck for tapping. They have a self tightening feature that is activated when the shank of the tool slips do to torque on the shank of a drill bit. Taps generate way more torque than a drill bit. In fact they will self tighten to the point of cracking. (Don’t ask me how I know this.). Since that occurrence I always use a keyed ball bearing chuck for power tapping.

[@woodscreekworkshop9939]

Not a concern for me.

[@troyam6607]

i find doing the ole fliparoo on the deckle clone gets the right side done just have to reverse your relief angle 😁

[@jescheffler]

Even though I LOVE to complain, Jason @ Fireball tool did a nice video on how it actually can be better to back drag your file. Also, I am pretty sure you are supposed to bleed into tool wrap. It's a DNA maker's mark. The mfg's are just helping you with that process.
