Router Base Plate percision
I'm newbie to woodworking and have a question that I couldn't find an answer to on the internet.
I find when making plastic base plates it's difficult to drill the center hole perfectly centered with the edges.
The closest method I have found is to:
- Make a blank base plate with outside dim's to size
- Attach a piece of 3/4" wood to the blank
- Use template bit to route the wood to exact size of the blank base plate
- Using dial calipers mark the center on the wood.
- Clamp the assm'y to the drill press table
- Use a Forstner wood bit to drill the center hole thru the wood
- When the bit reaches the blank base plate, Stop
- Put water in the hole that is in the wood(to cool the plastic while drilling)
- Drill the plastic center hole
The result was the center hole was off center .010" for a .020 side to side misalignment.
Being a newbie, I don't know if I'm trying to be a perfectionist, or the misalignment will cause issues.
My question how close is close enough?
Thanks, in advance.
