Hearing protection when working with loud tools - what do you use?
Are these auto-muting ones good? They seem like a good idea, but how is it in practice?
My problem with hearing protection is that tool use is intermittent but I don't want to be deaf and oblivious the whole time. Nor constantly pull them on and off (or worse, in and out).
Lena Grandin and Ole Stilborg explain how a 1st millennium back-yard iron furnace works. It's like grilling bacon (ore) until all the fat (silicate slag) has dripped away, and continually adding more bacon until you have a hefty chunk of solid meat protein (iron). The grill consists of charcoal. A puddle of grease (slag) is left behind at the bottom of the furnace.
The reason that the protein chunk doesn't sink into the grease puddle is that it's relatively cold in the grease collection pit. Each droplet of grease solidifies as it lands. Eventually you get a thick layer cake of solid grease, whose viscosity is high enough for it to support the weight of the protein chunk.

Turns out: shellac mixed with some pigment makes a fairly usable marker fluid for #metalworking.
(I only had black pigment at hand, but it works equally well as the blue stuff. The ingredients were all already lying around in the shop, and I didn't want to spend the 25€ for a small bottle of the commercial stuff and wait for delivery 😉)
Making a small angle gauge (or in German: Schmiege) for #woodworking. So far it involved a lot of filing… but I'm only three hours into the project. #metalworking
Final sanding still took a good while, even though I was too impatient (and tired), and only wet-sanded up to 400 grit. I focused mainly on getting the edges straight, and break all sharp corners. So there are still some scratches left, but it will probably pick up new scratches anyway during use 😅
Drew the rest of the owl again - Added the green resin, sanded them down, fixed them in a necklace tray, and added some finishing clear resin to the White Mage and Astrologian class coins (also a broom I was making too for halloween)
Finished making a Giant Bolt (lathe drawbar) tonight.
I need to just sit down with some scraps and get good at single point threading. Cutting M12 threads into steel by hand with a die is hard. I kind of just stopped halfway down, decided that was enough threads, and turned the remaining should've-been-threaded space down to fit inside the threaded hole.
I'm trying to figure out how this hand wheel is installed on a threaded rod. There seems to be no threads in it and all there is is a notch. I can't find any videos on how this works.
If anyone can explain to me or point me to a video, I would be so grateful!
I'm currently giving mastodon.radio a try, thanks to the admins for having me!
I'm a #maker, with #electronics and (some) #metalworking skills. I'm also a #hamradio#AmateurRadio operator with a UK full licence, under callsign M0OFX (and one of the three joint and equal holders of the M0YIP club).
I'm also into #ReverseEngineering and currently working on the Jerrold/GI Analog Cable TV system (see #analogcable) and hoping to build my own #CATV head-end.
