The There Are No Stupid Questions Thread

Do you know what kind of driver the vnx2 is?

I’d just get whatever high drain cell is convenient for you. 30Q, VTC5D, VTC6, Molicel P26A, P28A. All are good.

No,I will use P26A for spares, second run. The only way to know there run time versus other batts is to get them. I know they will provide plenty of amps.

Here was my run[post] for tonight:

I picked the best setting for me. 1%/30% and 100%

It was 58F out tonight. Initial burst was for 5.5 minutes on turbo. Then a few minutes on 1% to cool down, then 30%[which is ~3200L] for several minutes where it won’t get hot, then back to 100%…………repeat cycle! :+1:

I’ve used my brother’s rotary tool to first cut then sand down small pieces of metal into even smaller ones a couple of times recently.
F.e. I made a couple of 10 mm MCPCBs from 20 mm ones.
Now I need to do it again, reducing 20x20 mm copper piece to about 8 mm in diameter.

So far I kept the work piece in my fingers. It was not safe and I don’t want to do it like this any more.
I tried pliers but since the jaws are not parallel, they grip only the edge and the work piece rotates.
I tried pliers with some paper, it was a little better - but only a little.

I considered vice but:

  • it makes cooling harder
  • I can’t clamp it in the room that is the easiest to clean - bathroom

Can anyone give me suggestions how to do it safely and conveniently?

Locking pliers ?

Thank you, this let me notice that I have tongue-and-groove pliers. I just tried - they work great for me.

Forgive my stupid questions (ohh! It's ok to be stupid here! ), but I'm look'n for a better way as well to rotary tool small chunks of copper:

  • what are tongue and groove pliers?
  • how do you guys prevent damaging the rather soft copper of MCPCB's with these kind of pliers with such a small surface area of the MCPCB to access?

tongue and groove pliers (not mine):

I used a piece of paper-and-bubblewrap envelope to protect the MCPCBs. Plastic + paper turned out to be adequate soft jaws material. Though not very durable due to water softening the paper.

Ahh, ok. I'll have to try this next time. Thanx!

Those Knipex at $53 discounted are a big investment, but might be worth buying if I had other uses. But they look like a smooth finish jaw so not sure if they can hold the MCPCB very well.

I got a few locking pliers types, but again not sure bout the teeth and adding cushioning. Some have teeth that are too big, or deep teeth that are hard to cushion. I'll have to see.

Maybe Harbor Freight has something cheaper than the Knipex?

We call tongue and groove pliers “Channel Locks” and locking pliers “Vice Grips,” though that might not be the real names. Never heard them called anything else, but a rose by any name would smell as sweet.

I ordered a Convoy M21C from Banggood. I just checked for an update and I realized that the shipping method says “Ocean Shipping.”

Does that mean the slow boat from China, or could it be the name of a shipping company based out of China that ships by air, and sea.

I think it’s transliterated from Oh Shin Shi Ping.

My first laugh out loud in a few weeks. Thanks! I needed a nice, big laugh out loud.

Thanks Lightbringer, I have to clean the coffee off my keyboard now. LOL!!! :beer:

I actually just used a pair of channel lock/tongue-and-groove pliers for the first time today for swapping a boat trailer jack… I’m buying some ASAP. SO much faster than setting an adjustable wrench.

Anyone know if the pocket clips are interchangeable between the FW3A and FW21A?

The diameters are different, so no interchangeability.

I used wikipedia to get the name. I knew the polish name, went to the right article and switched language. :slight_smile:

We usually call them slip-joint pliers…. sometimes channel locks. Never heard tongue and groove tho(except for flooring and other wood products) Not sure how big the piece you are trying to hold but I use hemostats(medical pliers) for holding small stuff…… works really well.
