In my case, makita's original battery (NiCd) didn't have any BMS (Battery Management System) whatsoever, but lidl x20v system batteries do have integrated BMS in the battery itself, so that protects you from any over-charging and over-discharging. So, any older, especially NiCd generation tool...

My take on no batteries for tools. Good old makita batteries died (NiCd). Genuine batteries cost another drill, so i made an adapter to use Parkside tool x20v batteries. Cheap as chips if you already have a 3d printer :D No beauty here, pure functionality. Drill served me another ~3 years, all...

80W CO2 laser cutter/engraver. Engraving all sorts - glass, granite, acrylic, wood, mdf. Cutting mostly ply/wood/acrylic/mdf, cant cut glass/minerals/metals. Most mirror backing mdf usually pretty close to the frame, bending them up doesnt leave enough of a gap to pull it out. Plus yanking...

Even better. Got the tabs for the moment, will get gun later.

Yep, thats the ticket, thank you very much. A ton of mirrors to make now :D

I've been doing mirror engraving lately. Buy used cheap framed mirror, take out pins and mdf backing, laser engrave back, paint, knock pins back in, done. But latest mirror i got uses wire staples instead of flat sheet metal pointy pins - if i pull them i wont be able to put them back in. Looked...

Well, this is bull hit. Did i hear someone say "don't lean on a belt sander, eejit" ? Meh, fixable...

Progress report. Fiddly bits done, all of the number insides are done. One ring perimeter on the inside missing, but that one is easy'ish. Picked up on some shortcuts, like using slotted head bolt as a guided hammer. Outer perimeter of the number went in in like 60 seconds using bolt head to...

Ah sorry, its copper. just plain multistrand cable split. single strand was 1.6mm diameter. My friend has a rolling mill, so made a flat ribbon out of that wire.

Well, always wanted to try. Got 1,6mm diameter wire squished in rolling mill, resulting in 2.3x0,8mm ribbon. Annealed with a lighter (that took awhile). Drawn out design in coreldraw, lasered the design out in 100x100mm chunk of oak. Gaps/stabs are 0.7mm wide and some 1.5-2mm deep. Now, after...

Its like the half-joke on pricing work (cheap/quick/fast, pick 2) but paraphrased: Big, Rigid, Fast... Big and rigid will be slow Big and fast will be floppy Rigid and fast will be small Applies to cnc, 3d printers and laser cutters. Got a big(for home use) and floppy laser cutter. Making it...

Well, oof, that hurt :D Thats me to a T. I'd kill to become an apprentice now, and being an IT guy for most of my working life is not helping. And yeah, sticking IT woodworking wannabees onto cnc of some sort would work wonders, me thinks. Especially those that had SOME similar experience. I'm...

Slate/glass/granite/marble/stone off the road - all doable. Engraving, not cutting. Some super soft stones can be depth engraved, but i havent tried any.

Today running out my blank coaster stock on my laser. Need to get a guilliotine and cut more.

No need, i'm good. Found some examples online, will make my own with couple of iron angles and a flat bar. I'll share pics when done.

Still need to redesign. Need to figure out some sort of tensioning mechanism, as fiddling with knots is not ideal. Plus, the nylon string over time stretches. At the moment whole thing hangs only on 3 points, instead of 4 or 5 as is usual. This was just a "proof of concept" thing i laser cut.

My assumption (about slaters guilliotine) was wrong. It has support on both sides of the blade. I was thinking your usuall guilliotine with one edge unsupported. Upon closer inspection of slaters guilliotine, i see blade moving in between two supporting/shearing edges. Which makes sense.

Ah, so thats the term - riven edge. What i want is a steep edge, not what i can produce by hand, which is usually very shallow, unappealing sort of affair. I've tried a good number of times and nothing good comes out of me hacking at the slate. I could buy them coasters but its an unneccessary...

Yup, pretty much. Buuuut, i lean more towards dungeon crawlers/rpg's(none of the mmorpg stuff though), so... Someone has to do a vid like this about that.

Been looking at options to cut slate coasters myself as i have abundance of material. However, i couldn't find anything beyond traditional slaters knife, angle grinder and tile saw mehods that would produce presentable edge to coasters. I've tried hand cutting with slaters knife - chips in way...
