OK, time for an update to our laser thread. Last week I took delivery of a Gweike G2 Pro 30 watt fiber laser with 150mm lens (not focal length of lens, but coverage area). I've played around with some SS and carbon steel engraving and am VERY impressed with the results. Still gotta get brass...

Well Hello yourself - just what part of Alabama are you in? Fill out the profile and you might be next door {g} My profile shows I'm in Baldwin Co, just across the bay from Mobile - anywhere neat you?

You gonna love it

That gives an explanation of why they've not shipped, but there is still NO excuse for charging the card until ready for shipping, or at least building forge so shipment is only a couple of days away.

A slurry is really needed - just chunks of dry ice won't get the temp down nearly so well as a slurry. All those air pockets between the chunks (even crushed) have a negative affect on getting the blade down to the -100°F range. I would think 10 liters is about the smallest size to be useful...

I agree with Taz, not sure there's any real world difference between DI and LN. It does "seem" like I get an extra 1/2 point, or maybe a full point extra R\c hardness with LN than I got with DI. I wouldn't bet more than a nickel on that though. Real world, not a big deal

WOW - Oct 15th? That's almost 5 months! That's surely an extended hold Dewar. My el-cheapo 10L Dewar will hold around 6 to 8 wks with normal use. It's stored inside a climate controlled room so isn't exposed to hot weather. I've checked the temp up in the vapors when dewar is over half...

Many dewars have a 50mm opening which is 1.9685" or 1/32" less than actual 2". I find a 2" blade that's 1/32" less is no big deal, just list as a 50mm blade. In the real world I find it's much easier to get a 1.95" blade thru the opening.

Bob, note that is only 9.7" tall, so would have only maybe 6" of space for a blade. Also as mentioned N2 can't be in a sealed container. Nor should it ever be transported inside an enclosed car due to the escaping N2 vapors. I think this is the item you're referring to: https://a.co/d/0tA9OrK...

Bummer - hang in there, it'll get better

Mike, I've been waiting for somebody else to chime in with more knowledge than I have. I did find the following by Kevin Cashen on https://www.americanbladesmith.org/community/heat-treatment-and-metallurgy/snap-temper-question/ ************************* Below 300F in simple carbon systems all...

Any idea of the steel? What Rc hardness? I'd think those are a couple of questions most folks would like to know... BUT, perhaps the name Neil Kamimura Chef Knife should tell me something? Well, I did a search on the name, and I do see they are a VERY expensive knife, but still didn't...

There are a number of reasons he's out of touch, vacation or trip isn't one of them. death, serious accident, etc can happen, but even then since it's been a month I'd feel the need to file a charge back to card just to cover my bases. Most good vendors don't charge the card until they're...

All that cold weather is why I live South of I-10 - but we sure had our cold weather a few days ago with 8.5" of snow and a low of 10°F temps. I'm concerned my lemon tree might not survive. I'm glad you're keeping this thread going, I think several of us are following with interest. Ken H>

You are getting closer - Congrats. That ribbon burner is going to be great. I've always wanted to try one, but the standard old burner I've got works ok.

Those are some NICE tight twists - I sure wish I could get those type twists. I clamp one end in vise, grab other end with a double handled pipe wrench. I can get a few turns, but they tend to bow too soon. I'm impressed with those.

3.5" cylinder with 18 tons? You must be running around 3800 psi? That's a lot of pressure. Don't most places suggest staying below 3,000 psi?

Yep, that 56C face puts another whole aspect to the motor search. Looking for a 56C 3hp motor for a press so it would match up with the adapter to the pump increases the cost a bit. I sure do like what a roll mill does. Keep us updated to your build. A rolling mill is about the same cost as...

Jesse, here's a 1 hp, 1750 rpm motor for a bit less: https://a.co/d/gv0D06V

I just watched the video and about the 10:26 mark Tyrell mentions the cost as $1800 + $500 shipping. Still not bad for a nice rolling mill. Cheaper than a press. Ahhh, men and their toys.
