Can someone recommend a cheap place in Manhattan where I could tap and thread 4 screw holes in a small metal plate? Very easy job. I have no idea where I can go for something like that.
If anybody knows a metal shop or something close to that that can do it, that would be great.
PS The screws are 3mm x 14mm (the ones that come with the AB QR-RED battery plate). I need to attach the QR-RED to a metal plate - but I need the 4 holes tapped and threaded. That would be it.
