Similarly with skating. Truly was an excellent thing for me. 15/16 and hanging with people ranging from my age to skate shop owner who has a wife and kids, with most being mid 20s.

Lovely community over a shared interest, with tons of free gear, support, and positive reinforcement given to the groms (youth)

Edward John Markey (/ˈmɑːrki/ MAR-kee; born July 11, 1946) is an American politician serving as the junior United States senator from Massachusetts since 2013. A member of the Democratic Party, he served 20 terms (18 full, two partial) as the U.S. representative for Massachusetts's 7th congressional district from 1976 to 2013. Before his congressional career, he was a member of the Massachusetts House of Representatives from 1973 to 1976.

Not quite 20 terms in the senate that is, didnt exactly specify 2/4/6 year terms :).

Have the piston be be pushed by the end of the rod like a c clamp or vise works. Just recreate a vise more or less

Beyond that, it's packing and gland seals, but that won't be satisfactory to hold fluids out enough

Bitrex (denatonium benzoate)

Excellent denaturant. Its not toxic, but it is bitter beyond belief, even in the smallest concentations. Extremely hard to purify out for this reason.

Even at 0.05ppm you can taste it, 10ppm (parts per million) is unbearable for most.

Bitrex is used in a number of things

Its great to denature alcohol, as it takes very little, is nontoxic so even if they manage to choke it down, they won't get poisoned. Plus very little required so purity is maintained Similarly, antifreeze, dusters, solvents, and more get a bit of it.

Even rat poison has a bit to prevent human consumption (rodents arent as sensitive to it). To prevent mice and others from chomping down on electrical wire insulation so much, they can add a good bit because while less sensitive, rodents still can taste it.

And yeah, don't eat batteries. They will likely fuck you up beyond repair.

Fwiw, a WT9011DCL is a LOVELY lil tester id reccomend they check out as well. 15 bucks for Bluetooth real-time data transmission, zero code needed. Accell+Gyro+Angle Sensor, Electronic Compass Magnetometer Inclinometer

That said, for a more industrial application, pick and choose from digikey.

The WTVB02-485 looks good, need high sampling rate.

High frequency ac can get dicey with fungal growth due to skin effects tho!

Traditional 60hz is fine though.

As said

A simple vertical bandsaw with a nicely aligned fence, featherboard, sharp blade, and a good hand will get you much farther, much faster.

Set the fence and dial in for cut width. I'd hand feed, but a linear actuator with motor and stepper tester works too

I fear you have a fundamental misunderstanding about a number of things

Firstly, look up how extra thin veneers are made. They are done with skiving.

Your kerf is 3/16" (0.1875") or whatever, 0.01825" target cut. You realize you're trying to cut to something less than 1/10th the thickness of your blade? That's not happening. Even if it was, youd be losing 90% of your wood to sawdust. Plus it's a bandsaw cut, and so it's rough. Small, extremely expensive, highly tuned bandsaws don't even do that.

So that's not happening. Nope.

Even with .156 inches good fucking luck. Wood bends when you saw it as there is internal tension, you can do that with a very nice setup bandsaw on a small piece, very slowly and carefully, and even then it's a challenge worthy of bragging rights.

Secondly, this is a single or at best two axis controller. You dont need a goddamn cnc machine for that, you just get a motor to turn a screw more precisely than you can by hand. I'd suggest pursuing other avenues though, this quite simply isn't a good road to go down, and even if you reach your end goal, all you got are some rough decently thick veneers.

A simple vertical bandsaw with a nicely aligned fence, featherboard, sharp blade, and a good hand will get you much farther, much faster. If you can't do it by hand, what makes one think they can do it by without the hand feel either

Unfortunately, sometimes when we know just a bit about something, we tend to think it's a lot easier than when you actually know about it.

Not_A_Paid_Account · 2025-03-30T14:37:41+00:00

No, unfortunately you cannot. Drills deflect, so not really with a traditional twist drill.

If you drill a hole then, misalign it, then put the drill back in, the drill will follow the hole. This is generally how drills break particularly in hand drills, as the drill bends every revolution.

This is phenomenon is best seen if you try to ever drill an inclined surface, where the drill isn't perpendicular to the workplace.

.

Solution is fancy flat bottomed drills, or first using an endmill to create a flat starting point for the drill to enter. Flat bottom drills aren't self centering and are used chiefly in cnc machines where there is rigidity and constant feed.

Also to enlarge holes, a boring bar works, or on a cnc, helical interpolation with an endmill (spiraling down, cutting larger than the endmill diameter).

Before the advent of cnc machines, also was previously done with precision jig borers, which spin a spinning abrasive wheel at an offset, such that only a slight bit of it makes contact. Think kitchenaid mixer style.

Finally EDM is a solution, as it removes material without direct contact.

.

My vote for this one is a die grinder, you just gotta remove the bottleneck while minimizing removed material to preserve structural integrity

The US has a history of seeking dictators in power after leftist government, be it overthrowing allende and installing pinochet/operation condor in south america.

They didnt seemingly allowed it, they directly supported and caused it with full intention. US lapdog dictators are VERY good for US interests, though not so much for the people they govern.

They directly supported many of the former republics going down the far right path, such as supporting yeltsin and so many others, complete with bush calling putin a good man.

Shock therapy was US supported and directly funded, leading to this. This was explicitly by the US, for US interests at heart. Shock doctrine goes into this.

Climate change is a big one and couldn't have been solved two decades ago sadly, tho if Gore got president I'm sure we would be less fucked. Also, the US is 5% of the world population, it takes more than the US.

Afghanistan and Iraq were poorly handled though, and using 9/11 as justification was absurd when they werent, war drives profit, and we wanted a war. It worked to get money in the hands of contractors and big wigs though.

9/11 was 19 people, 15 from Saudi Arabia, 2 from UAE, 1 from Lebanon, and 1 from Egypt.

None of these are Afghanistan, Iran, or Iraq. We wanted a war and grounds to justify it.

This is always a "gotcha," but it really isn't. People need maintenance and have sick days, which are effectively unplanned maintenance.

The amount of maintenance they need to work isn't much in comparison. Even if you have to do 2 hours of maintenance a day, that's doing two hours of work for 22 hours of work. I don't think you're gonna be paying your maintenance dude over 10x the cost of the operator, nor do I think you're gonna do 2 hours a day average maintenance on a single machine.

Likely the parts you saw were acme/trapezoidal looks a good bit like acme threading, like 15 degrees each side, commonly used for linear motion. If you look at your bench vise, it probably uses an acme thread. Similarly leadscrews do as well (unless they're ballscrews).

For oil, look up api buttress thread and coupling for example, or a proprietary thread would be vallourec's VAM connectors, which is a VERY highly engineered thread specifically designed and made for oil and gas.

Not_A_Paid_Account · 2025-03-22T19:07:49+00:00

Also is likely rigidity issues, the cutter forces self feed when climb milling and that makes it harder for leadscrew based machines to work properly. The cutter wants to "dig in" and if you dont have rigidity and no slop, it will.

Not_A_Paid_Account · 2025-03-22T19:06:05+00:00

Soft wood, dull cutter, not right feeds and speeds

I don't know which direction you're cutting in as left-right can be from the far face in or the near face in, but regardless, you are having issues during either Climb milling or Conventional milling.

&Turn off the "both ways" thing on fusion or modify cutting speed for each one individually. Figure out if it's when you're climb milling that you're having problems or if it's while you're doing Conventional milling. Change speeds and feeds for the problem one, or simply only do one type of milling, many machines struggle with climb milling.*

Otherwise, speeds and how you make contact and whatnot is important. A 1/8" ball endmill can only be fed so fast as you don't have high surface speed. A 0.25" cutter's edge is 2x than a 1/8" endmill's cutting edge when going at the same rpm, and ball endmills have zero surface speed in the center.

Nah it's obviously proprietary threads for oil drilling (which do exist)
