What's going on in your shop? Show us whats going on, and talk a bit about your work!

Here it is. As you can see everything else went pretty well (still polishing the bolsters and handle) but that one slip while peening made the front off my enough to piss me off, and there is a glue line that I did not notice!

On a positive, the overall design followed my intentions and I will be making more! You can see the influence of the Case trapper.

Will normal stainless wire work to hang the blades in the Dewar if they won't fit into the holders? I may take some thicker barstock and drill and tap it so I can bolt these blades between 2 thick pieces of bar stock so they don't warp in cryo. Just gotta make sure they can get thru the neck!

I use Aircraft stainless steel lock wire, a thin diameter, for hanging blanks in the dewar.

Do you often have warp issues in cryo?

Never done stainless or cryo before! First time for everything!

Using stainless wire for holding blanks in dewar I picked up from Jarod Todd.

I rarely have any issue with warping blanks in cryo, I have to wonder at times if this has to do with running a stress releiving step pre ht.
 
Are you doing a 1500 degree soak and slow cool before HT as a stress relieving step? I was thinking of doing that a few days before I do the HT.

1100-1300°F with 2 hour soak and oven cool or still air is the standard from the data sheets.

Pocket fixie in Magnacut all done, waiting for the storm to pass before shipping it to Florida!

Magnacut hunter going out this week with the AmeriGrip handles:

Both Magnacut blades:

Small O-1 Paring Knife with Current Composite Liberty Wood handle scales. This is like the older Dymondwood. Less splintery than Dymalux, colors are brighter and the wood itself is harder and doesn't scratch/dent as easily. It is supposed to be able to pass the boil test as well so the grain should raise when exposed to hot water/steam! Decided to use some Mosaic pins for more bling. Current is going to get some pictures of this one for their website to show what the material looks when shaped. I just took it to 600 grit on the belt sander and 800 by hand, then Tung oil on it.

Got this trio finished up too! Orange/Green fabric laminate handles, premade Oyster blank with the tip flattened, Nitro V paring knife and a CPM154 fillet knife:

Started blank prep for my first Stainless Heat Treating! These are Magnacut, 3/32" and 1/8" thick. 2 FBBO and 1 FBBO Reverse Tanto in each thickness, plus 2, 3.25" Drop Points:

And 2 smaller pieces from the end cut offs of the bar that will become smaller 2.5" or so blades, hidden tang style:

So I got 10 blanks out of 6' of Magnacut!

My liquid nitrogen dewar has "speciman holders", so I have to see if these blades will fit into them or not.

Will normal stainless wire work to hang the blades in the Dewar if they won't fit into the holders? I may take some thicker barstock and drill and tap it so I can bolt these blades between 2 thick pieces of bar stock so they don't warp in cryo. Just gotta make sure they can get thru the neck!

I hang my blades in my dewar with 1/16 stainless rod.
 
Thanks all! Got my duck bill pliers and seam roller in. I thought I had read about a 1500 degree stress relieving cycle somewhere, so I am glad I asked! I gotta pull the data sheets and figure out how I want to do the aus. temp time. I would like to get 63ish hrc (these are smaller ~3" blades, so not big choppers), but would prefer to temper at 350 instead of 300, so I am looking at the 2150 for 10 min soak then quench in aluminum plates then into the nitrogen.

I will test the blades in the specimen hangers that I have; that would be nice to use if they fit!

I am not sure if it matters but I do cover the blanks I am stress releaving with an old peice of foil so the blanks are not exposed to any direct radiant heat. I also run ramp at 500.

I don't know how well it will work using the specimen containers for holding blanks. If you are trying to get all 12 blanks in the dewar at once you might have issues removing the blanks. 15 blanks in the dewar is about my max and that is using the thin wire with 3 blank bundles.
 
Ok, I was going to use some of my cheaper 321 foil to protect them. My oven gets to 1100 in about 20 minutes or so (fire bricks are heavier than they should be), so I will put them in and let it ramp up slow and then hold and them shut off. Will be good practice to get used to using the ramp/soak PID! I got the wifi connectivity issue corrected, so I can monitor and adjust my PID from my phone!

The specimen holders look like this, so they hang to the outer portion of the Dewar, which leaves the neck open all the way down. I can remove the holders one at a time. It's an 18L Wharton Taylor XT, supposed to hold for a couple months! Got it for free at work when they were getting rid of it!
 
Anchorsealed a big, true cocobolo burl slab yesterday, and just thought you guys would enjoy this (stick around until I spray it!). This is only the second time I've had cocobolo burl.

Should be ready in a year+. 😂

Moisture content is around 15%, so really not too bad.

I was saying to myself: “That’s some beautiful wood!" And then you sprayed it down ...😲

I'm working up the nerve to try bolsters- that's some good work you did at this point!

it's also nice to make things a little easier for myself from time to time
