Hello fellow Canadians,

I've recently received various phone calls from the RCMP (not real RCMP- however, they are able to change their caller ID to legit RCMP phone numbers).

The caller claimed to have confiscated data from a hacker group and my data was compromised.

The "customer service" from my Hardware Cold Wallet (Trezor, Ledger, etc.) Would call me to make sure my assets weren't compromised.

The first thing that set me off was the speed between the "RCMP" calling and the "Support" follow up call.

Now please don't judge me for not realizing this was a scam right away. The fake police officer had a enough information about me to assume he may have been real and didn't actually want any information from me in return. His caller ID also checked out.

Luckily I wasn't home so I wasn't able to do what this "customer service " agent wanted from me with my wallet. He scheduled a call back. After a few minutes of thought, my alarm bells went off. I called back the real RCMP with the officers name and it turns out he didn't exist.

I messaged the real Cold Wallet customer service and in their FAQs it says "WE WILL NEVER CALL YOU".

In all actuality my hardware Wallet did have a data breach some time ago. My wallet and coins weren't compromised but enough data got leaked for them to target me on this scam. I'm embarrassed to say I almost fell for this and don't want anyone else to.

Please be safe and vigilant. If police ever call you, hang up and call back on their official phone numbers.

Hello community:

I'm having a intricate piece of Stainless Steel 3D printed. I need to put various holes into in with a drill press. The total thickness of material is 2mm.

Now I can have "holes printed" into the piece for alignment or centering, I just want to drill the final actual shape with a proper drill.

Last time I did this I put a 0.5mm pilot hole through the material, but because it was so little it wasn't truly round and didn't help much.

The hole needs to be 9mm in diameter, so quite large.

Now my question: How should I design the "pilot" for the ideal centering of the drill ? Should I make the hole 7mm with a bevel so I only need to drill out 1mm all around the hole ? Should I make the hole around 3mm and use a center drill ? Spotting drill ?

There are so many options here, please help!
