I am going to build my 1st laser rather than purchasing it. I came across
a Surefire 6p flashlight host in an old tool box. Would this make a sufficient host, for a 445nm 1.2-1.8 diode? I believe the power source is 3 -3volts.
(I could be wrong..might be 2) See pic of host example.

Thanks

Unless you find some crazy badass boost driver, you'll need more voltage for a 445nm laser, usually need >5V for 405 - 445nm. The 3V would be OK for a 650nm red laser though.

What batteries can it take?
If it takes one AA then you can use a 14500 li-on 3.7v with a flexdrive V5 set to 1A. It will output around 1W with 445 coated glass lens.
The run time wont be nothing special because of the size of the battery.

Yes, that should be fine. Powersource generally speaking is 2xCR123A, you can go rechargable with 2x16340 Li-Ion, or go with a more complicated boost driver and 1x17670 Li-Ion.

Radiant sells heatsinks for the ultrafire P60-style clone, however I believe ultrafire uses larger dimensions, probably won't fit in the 6P.

I had a heatsink made by one of the many talented metal lathists here, FlaminPyro, for my Solarforce L2, which is basically a 6P based design. Heatsink fits like a glove, doesn't slide or wobble, heck, it makes an airtight seal, I have to remove the tailcap otherwise the heatsink will just pop out again. Anyways, I digress. Point is, heatsink you will want to have custom made.

I went with a 12mm bore to house either aixiz modules or 12mm green modules, but press-fit will perform better if your machinist has the correct measurements and capability to machine threads for the aixiz-style lens.

Basic parts list:
host
driver
laser diode
lens
aixiz module (if you bore to 12mm instead of a press-fit heatsink)
heatsink - make sure you have driver dimensions and lens dimensions to make sure there will be space for the driver and lens. I sent my host to the machinist so that they could see how it would go together.
