    Resp-O-Rator R.I.P.

    Interesting design, thanks. A couple of questions: - Can you post a photo of the mouthpiece, it's unclear what it's shape is or how it inserts into the face frame. Also, does the male filter bayonet (on the face frame) accept 3M filters? I might be interested in this kind of filter IF the...

    First forge questions

    8" diameter seems small after adding a couple inches of insulation.

    New Chinisium Tig

    Good for you - TIG is like jumping into the deep end of the welding pool! One really critical tip for TIG, or really any welding, "If you can't see the puddle, you won't weld very well". You should be able to clearly see the electrode, puddle and feed wire. Get a Good (not cheap) electronic...

    Reverse Switch for Grinder?

    I use the reverse switch when sharpening on my 2x72 grinder, like this. I've added a small horizontal platen behind the upper 2" wheel But, I also use the reverse switch on my drill press and mill (which both have a VFD), as an aid in tapping holes. In fact I changed the Reverse switch...

    New Chinisium Tig

    One more thing - I just finished watching all of Walter's video about his welding machine. He's a terrific knife maker and makes superb videos, I've learned a lot from him. But as a welding video - ugh, not good. Like I said, watch Jody Collier if you want to learn about welding, either MIG...

    New Chinisium Tig

    Wow, that is indeed an incredibly >>cheap<< price. I've MIG welded for years, and have a pretty good TIG setup (however I'm NOT a good TIG welder). You likely know the benefits of TIG - but here are the issues that I have with TIG. It uses lots of pieces and parts in the torch (eg $$)...

    KnifeDogs Adjustable Disc Grinders Now Available with Motor & VFD options

    I've held off buying or making one of these grinders, just haven't seen the value...yet. However, there are so many folks who rave about these disk grinders. This overall design looks solid with good adjustment features. I like the thickness of the plate steel and insert tubing. However, the...

    Is Majestic Forge still in business??

    My read of Majestic's response is that there may, or may not, be legitimate issues impacting the business. It's a poorly written set of excuses for bad customer service. Like others have said, do anything you can to get your money back and then look for another supplier. Thanks for sharing...

    New shop tools and a new deck

    Sean: Nice work, that deck looks great! What kind of wood did you use? The railing pickets are looking good too, nice twists. You've got the right idea, buying tools is an investment that keeps paying dividends - particularly that welder. Looking forward to seeing you again at the SLC Blade...

    Another Thin Nakiri

    Josh: Timely question. I'm tempted to do an S grind on the next blade, I've got 2 more Nakiri blades post HT waiting to be ground. My only hesitancy is I'm not too sure how well my 10" wheel will work for that, and I"m unsure about how much depth I should have in the S grind relief. The blade...

    Vermiculite or Pearlite

    Got a chuckle out of this thread, butt it all deepens on weather your looking at steal or durt. Saw a sign the other day on a guys driveway: "Please Clothes the Gait" ;)

    Another Thin Nakiri

    The Nakiri has turned out to be one of my favorite kitchen knives. It's like cutting with a razor blade, the perfect "machine" for slicing vegetables & other soft stuff. 52100 steel, .080 spine, .010 edge before sharpening, full flat freehand grind. I don't try to get a precise finish on the...

    I am up against the limits of my capabilities

    Ken: I'm interested in seeing photos of how your re-grind worked out. Looks like it could be challenging.

    ArmorAll finish giving me fits

    Hey Chris, I've tried this process a couple of times and didn't feel the results were very good. Questions: do you the "Original" version of Armor All, or some other variation? Do you let the Armor All dry before putting on the TruOil? Then how much do you rub it to remove the whitish color...

    Grit Size Equivalents

    I am always asking myself, what's the grit size equivalents between the "P" grit on a bonded belt, the "A" rating on a Trizact belt, and a micron size. Well, here's a handy little chart that mostly matches up those 3 grit designations. The bolded numbers indicate common belts that I use. I've...
