Can I use this P&W 2A jig borer as a milling machine

Here's a jig borer

Before I scrap this thing, I wanted to know if perhaps I can use it as a milling machine, since it has a DRO. Thanks

Watch out for the tooling -- it requires special P&W collets.
Like any classic jig borer, the spindle is great for accuracy but not so much for handling lateral loads. It's made for drilling and boring holes.

Yes, I know, but it does come with collets and such.

So, what would happen if I start milling with it, collets will fall out or spindle would fail, or what>

'Can't tell you specifically. Back when I was reporting on these things, the transition from jig borers to jig mills (like the DeVlieg) was a subject of a lot of discussion about spindle bearings and spindle diameters, spindle-bearing arrangements, and so on. The fact is that jig borer spindles are made for highly accurate drilling and boring, and just aren't designed to take much of a side load.

Well... of course you CAN use it as a mill, Ig. But it's DAMNED big, and DAMNED heavy. How much milling of the sorts of sizes and weights that thing will handle do you actually do?
I would think something more like a common BP mill would suit. You can always rip the DRO and scales off that unit before scrapping it.

I do not do any heavy milling, just for maintenance purposes or some such, the biggest would be a 3/4" end mill.

I always take DROs off...
