I just ordered some 3/16" magnets to do some swappable arms on some of my BA. I was just wondering how you guys drill into plastic models with a bit this size? I use a pin vice for 1mm-2mm bits, but I'm not sure that turning by hand alone can drill a 3/16"s hole into plastic.

Thanks.

I use a dremel

I'd never use a dremel on plastic, you end up melting through rather than drilling.

3/16" is about 4mm so you could consider getting a Tamiya Hobby drill. It's a model kit and a tool and ideal for small diameter drilling.

Alternatively you could get a pinvice that accepts bigger drill bits. I have a double ended one that had removable double ended collets ranging from 1-4mm.

If you can lay you hands on that then drill apilot hole as big as your pinvice will allow, then use the 3/16th bit to bore that out. A bit time consuming but it shouldn't be too much trouble in plastic.

I have also use cheap hobby knife handles (with plastic blade holders/collets) to hold larger drill bits.

I just use my regular cordless drill for 3-5mm.

Slow speed, and a couple of turns usually does it.

I've used this thing for years, though - so I know how it responds to various materials.
