I understand what you are saying. It is hard to get a straight hole without a drill press. It can be done with a bit of preparation just not as easily.

Use a 6” long bit and make a block of wood to stand next to it so it gives you an idea how straight you are as you drill.

The above is suggesting another improper federate which when coupled with the fact the set-up has no rigidity will equal intolerable tolerances.
If doing this by hand and you want accuracy?
1. Predrill center with dedicated center drill.
2. Drill thru with undersized bit "The next size smaller in whatever scale is being used."
3. Ream by hand using a hand reamer tool, cutting fluid and patience.
Or; Spend $25 at the local pawn for a drill press.

That'd be "DOOOOOOOMED!"
And no, I still cannot spell "federate". because this nifty pc keeps changing it to "Federate" And I am just too old to start spelling it "Feed Rate".
