Next week I am buying this floor standing drill press, used, from some rando. I will have the chance to put a dial indicator on it before taking it home. What should my go/no-go limits be for runout on a $400 used drill press?

I, too, am looking for comfortable workwear for hot weather (anything over 60 F tbh). This is for welding, so it must have thick fabric and full coverage, long sleeves, etc. And no fans allowed (blows away the shielding gas). Unfortunately, I think welding is just always gonna be hot and sweaty.

BIG-DICK-BUTT-gently caress posted:Why tf is the M12 die or right-angle grinder so drat expensive? Brushless motor, electronic control board, gearset = $189 tool only??? I bought the M18 straight die grinder. It is big and only has one speed. I liked it so much, I also bought the M12 right angle die grinder. I really like the way the variable speed works on the M12 (variable speed trigger & 4 way switch to cap the max rpm). The M12 has finesse that the M18 definitely does not have. (Both are good. Just get both.)

Have you ever done some shaping or grinding that was a little too big for the Dremel, but you went ahead and it kinda worked, but not very well? You need a die grinder (or two). Electric die grinders are bigger and heavier than a Dremel, but they can be more precise and more delicate for certain tasks. They are way less likely to bog down, so you can push them harder and have more control while doing it. That's the key thing, they have the power to be smooth. My favorite tools: Lennox Metal Max diamond-coated blades: 1.5" and 2". If you have the M18 die grinder, also get the 3". They seem to last well enough, and they won't explode like abrasive discs. Consider that these die grinders don't have guards. 2" Roloc abrasive pads. The die grinder will spin 2" scotchbrite fast enough to throw sparks. Really nice for surface prep. Carbide burrs (rotary files) are nice for shaping metal, although they create the most vicious chips of any metal cutting tool.

I'm building a 300W buck converter so I can power 12V car stuff off my M18 chainsaw battery. Things like a 50W ham radio, air compressor, small inverter, etc. Output will be 14V @ 20A. But I have a ton of projects going on, and this is a low priority. Probably something for 2023.

withak posted:You can't dispose of children's hands/arms in a drain. Rufio posted:Coming soon: M18 wood chipper That reminds me, Milwaukee is coming out with a new M18 Pruning Chainsaw soon. Presumably this will be a step up from their current M12 pruning saw. The timing is perfect, because I've been wanting to mount a small chainsaw on the front bumper of my van (not full time, just for special occasions). When I go camping early in the season, there are often many, many small trees fallen across the road from winter storms. On those roads, my forward progress, in miles per hour, is dominated by the time to unpack, use, and repack my full-size M18 chainsaw. But with this pruning saw mounted in a scabbard on my bumper, I can just jump out of the van and start severing limbs immediately.

Hexigrammus posted:Anyone have experience with arborist's winches? I've been renting a 3 ton Tirfor wire puller to take down dead snags but rental costs are getting to the point I might be better off buying than renting. No Tirfors on the second hand market and new are a bit too pricey for my taste. Cheap ratchet winches break easily. I've cracked a big one pulling with one arm, no cheater. They're garbage. I use the Wyeth-Scott puller to pull my Sienna minivan out of ditches while offroading. Note that the 3 ton rating is WITH a 2:1 pulley, so it is not as strong as the $1,000 puller you linked (also weighs half as much). That said, the Wyeth-Scott is a very strong, heavy duty puller. I like mine. The AmSteel synthetic rope is EXTREMELY WORTH IT.

My brushless Milwaukee sure does stall if the chain binds. If the chain stops, the motor gives up instantly. And of course you pull the battery out before unjamming it.

Does anyone make a fast cordless drill? I want 4-6,000 RPM. Why doesn't Milwaukee, say, make a small, fast M12 drill? It's like they cannot, will not release a drill that can't sink 3" deck screws. This is to drill pilot holes in steel.

Drill Press Wheels This bastard weighs 150 lbs, so it is a real pain in the rear end to move. I want to add a pair of wheels so that it can be tipped back and rolled around. The idea is that when upright, the wheels won't be touching the ground. I don't want to add any wobble. Putting the wheels in front would be a lot more convenient for backing it up against a wall, but I think I will put them in the back where I'm less likely to trip over them.

Casters will wobble. It's very top-heavy. Maybe it's not 150 lbs and that's just shipping weight or something? I haven't actually weighed my drill press. It's heavy enough that I can't just pick it up or easily drag it around. But grabbing the top and leaning it onto the floor, or lifting it back upright is not hard. I don't think it's a huge safety hazard (like you're not going to get pinned under the machine or anything).

Aha! A tool I need that I didn't know existed. (Not even a theoretical need, but something I'm planning to do next week!) This is how aircraft builders countersink rivets with precise centering and depth: Micro-stop and countersink. This is for 120 degree countersinks, so the bit is not strongly self-centering (not very pointy).

brugroffil posted:I have a 1.5 ton powerzone floor jack. It will hold pressure if I manually lift up the saddle, but the pumping piston stopped extending so I can't actually pump it to lift anything. Is this repairable or do I just need to get a new one? The pumping piston is sticky, and the spring is not enough to overcome the grime and dirt. It is very easy to fix, just 2 screws on mine. The pistons just pop out by pulling, and you can clean it all up with some paper towels and brake cleaner. This is assuming they're just dirty. There could also be rust or damaged o-rings, so check for that. On mine, I did not need to top off the fluid. https://www.youtube.com/watch?v=IvFUREOoe6U

Hmm, my homemade power supply seems capable of insta-killing Milwaukee M18 6.0 and 8.0 batteries, leaving them with 1 blinking red bar. My CP 3.0 works fine. My power supply is drawing power from the battery, not charging it. I'm pretty sure I'm not over-discharging the cells. It seems more related to moderate-current draw. I was pulling about 100 W at 75% SoC when it killed my 8.0 battery. Plugging the blinking battery into a charger briefly (only 1-2 seconds) fixes it. I'm quite sure that I'm not physically damaging the cells, since I'm only pulling 5 A or so, and not running the batteries flat. I know Milwaukee sells 'dumb' M18 tools that only connect to the raw battery +/- and not the communication lines. But they tend to be low-power tools like LED flashlights. One possible theory is that the battery is mad that I'm drawing moderate current without talking to its serial port and asking permission? Lol. e: 8.0 battery does not get mad when discharged at 20 W. 8.0 discharged all the way to 3.10 V/cell (empty threshold according to onboard BMS, 1 blinking bar). Now I'm discharging my 6.0 at 40 W and it's happy so far. I know my 12.0 chainsaw battery gives no fucks because I've paralleled it with a dead car battery and it didn't seem to mind (with a 40 A fuse for safety). But that battery is a few years old. The 8 and 6 that are giving me grief are newer, and maybe have newer guts? I'm pretty annoyed the M18 comm protocol hasn't been reverse engineered yet. It's 2000 baud serial with no encryption, how hard can it be? The batteries have a TI BQ76925 battery monitor controlled by a MSP430 microcontroller. Teardown with partial schematics. The M18 battery boards seem like a TI reference design with minimal changes. Just discharged the 8.0 at 75W, ramping up to 200 W. This is enough power for my use case (50W VHF ham radios draw 100-200W). The battery threw an error at 220 W, at very roughly 50% SoC. I should take one of my batteries apart to see if it is sensing current or just cell voltage. The M18 battery LEDs seem to be based on cell voltage, not charge integration. latest: The 6.0 and 8.0 batteries throw an error for loads greater than about 220W or 11A. It's probably based on current, not power. Above this, and the battery quickly throws an error (couple seconds or less delay). The BMS can't electronically disconnect the battery, so these errors are advisory only. Battery error is based on current, with a trip point of 11-12 A. My power supply doesn't have precision current metering on the input, so I don't have precise numbers. I wonder if this 11 A trip was introduced to new batteries JUST because people where converting Power Wheels to use M18s without any over-discharge protection and killing the batteries? So flip on the blinking light if there's high power draw without serial comms and scare the owner from trashing their $200 battery. Internal cell specs for every M18 battery:

casque posted:My Milwaukee M18 charger gave up the ghost. Where's the best place to get a deal on a new charger + battery? If you just want a charger, buy an open-box genuine charger off ebay for $20-30. People buy the tool 'kits' to get the extra battery, but don't want the extra charger. If you want a new battery too, buy a kit with a tool. More M18 battery communication reverse engineering. The comm protocol is extremely simple, but nobody has bothered to reverse engineer the details yet.
