By the way- it is official- I now have a new hobby.

En route are a 0-120V 1A power supply, a container of Multi-Etch, 3' of Niobium wire for jigs, plastic mesh, and stainless foil.

When I get home, ordering G10/CF, knifemaker-grade Ti for liners, and chainring bolts.

:cool: Good to hear that!

Dearly beloved, we gather here today to mourn the death of our dear friend Bako's wallet. It lived a full life until it got the bug. Knifemakers bug. It is often a quick and painless death.

Haha, have fun dude! Congrats on the weight lo$$! :D

^True! :D

Designing is going well this evening, I have an Altoids Tin Knife drawn up and a start on a Dogtag tool or knife.

So far the dogtag tool has a bottle opener, a finger hole for orientation and possible knife use, maybe a "meat tenderizer..." any ideas guys?
 
Xander,

Right now I'm weighing the possibility of making enough of them to warrant water jetting the blades and liners. As long as I'm buying a bunch of stuff, I might as well do it up right from the giddyup and sell a few to offset the cost of getting started, eh?
 
Morning gang!

Grrr, I'm still all bent outta shape over some D-bag almost running me over on my bike last night and then being a prick about it right from the start of the conversation. There is a much more colorful account of it over in W&C, if you care to read about it.

Am at work now, gonna be a long boring day.


Happy Friday y'all!

Zup Gang!
Everybody relax...
Gald you are ok, Xander.
fyi- Pohan is sending me a piece of A2 and I will make a knife on my emory wheel grinder. Hang on!

Xander I just read the thread, what a douche you encountered! I had something similar happen... long story but I am glad you are OK.


I took the day off... I ground the screwdriver bevel on 50 Ti Keychain tools yesterday so I needed a rest. I still am excited to grind that many in one day.

I hope you guys had a good one! Enjoy the evening. :D I'm going to work more on design...
 
Glad you had a day off, Daniel. I'm having my first in 3 weeks tomorrow.

CAD is annoying, ad tries what little patience I have at the end of the day- therefore I have decided that the modern, evolved man in this situation gets out his wallet and gives a starving nerd from Craigslist 50 bucks to do his CAD drawing for him. What I want to know is, I grind my little blanks *after* HT, no?

Hope you all have a relaxing weekend with your respective loved ones and/or barricaded in your respective workshops with a bottle of liquor, makin' stuff.
 
Do the majority of grinding prior HT, then sharpen after HT with a slow speed grinder. All grinding AFTER HT would be slow and wear through belts too fast and possibly screw with HT if you rushed it and sped up the grinder...

I have ground out ONE, no two knives.. from bar stock Daniel gave me over a year ago :D One looks great and I might actually one day, in my life, have it HT'd and finish the damn thing! :)
 
Oh, did I mention profiling will be done by water jet?

I'm getting .250" thick blanks- starting with the big shit right away. I'm worried about losing them during HT, and as this is the first time I'll be beveling, it's going to go really slowly anyway. I'm thinking of trying a variable power supply for a rotary tool for my 1X30 to see if I can get that nice slow speed. Hmmm...mebbe I'll go to HF tomorrow for one.

That is a long stint Bako, I hope you get some time off soon. Food mines! yarggh!

CAD - sometimes it really ticks me off! :D I barely get the 2d stuff after a year of working in it almost daily. There is usually a lot of swearing involved. Now I'm good at it but need to learn Draftsight...

The waterjet guy can go from your drawings or templates. My neighbor here on the subforums Mark at Leading Edge Fabricating is the best. There is a charge for setup but I'd consider talking to him first. $50 for CAD work is great though. As always just let me know if you need help with anything! I like seeing everyone do good...

Grinding - it is more common to grind before heat treat, in general you grind to .030-.040" thick (leave them thicker at first) then do more grinding post HT.
Without getting in to too much detail - High carbon steels will decarburize during HT meaning they lose their outer skin of carbon, Air hardened steels do not as they are heated in a somewhat inert environment. I grind just about everything bevel wise post heat treat but had to work up to knowing how to.

So with O1 (is that what you got?) you want to leave a thick edge, heat treat, regrind everything. The standard would be to finish the flats and bevels to 400 grit then go back to 120 post heat treat. There are many ways to do it.

Do the majority of grinding prior HT, then sharpen after HT with a slow speed grinder. All grinding AFTER HT would be slow and wear through belts too fast and possibly screw with HT if you rushed it and sped up the grinder...

Good call on grinding slow! Fresh belts and slow speeds are the best way to keep the knife cool.

Nice! tip - You will still need to clean everything up post water jet, make sure you have a tiny bit of extra steel on your design's profile to grind off. Good call on getting them done that way.

Grinding Bevels - that is one of the tough parts, practice is key... I'd do the major metal removal with the grinder (get ceramic belts, 80 grit 3m cubitron 2) and then switch to files. They will remove metal almost as fast as the grinder, get a Nicholson Magi-cut for the flats. Draw file to perfection then sand with a metal block (with radiused edges) wrapped with sandpaper. Or plan B - get 8' of 1084 from Aldo and grind it all! Scribe your grind lines in if you want, that helps.

We need pix...

Pix!



Morning guys!
 
Morning y'all!

Congrats on 27K Rolf!

Bako, just buy some ceramic belts for your 1x30 from Pops and do the grinding bare handed so you can feel it heating up. Use a fresh belt every blade, it will work wonders and result in cleaner grinds. A variable speed drive for a rotary tool will not work, those are DC motors. Also, depending on which 1x30 you have, you may need to upgrade the platen, make sure it is flat and is up against the belt. A file guide will make your plunges really clean and even, but also make sure your platen has the same radius on each side.

Just got to work, gonna be another boring day. One of my employees, his last day is today. He's leaving for the Air Force next month, so I gave him one of my liner locks, a CRKT M16-13. The good one they don't make anymore, AUS8 blade, aluminum scales, non-auto LAWKS fighting lock. I didn't carry it anymore and he has been looking for a decent folder. Its more than I know he would have spent on one for himself.

Have a good weekend everyone! Tomorrow I am going to the asparagus festival to watch the 25,000 drunks and hippies dance to Fog Hat. Always great food, and a good time.

Good stuff there Xander, you worded that a lot better than I did.

That is really cool you are giving the knife away, you are the man Xander!

Fog Hat - I saw them live once and didn't really expect much... they ROCKED! They were better live than the recordings, at least when I saw them.
