Finding the center of cedar block

7 posts in this topic

Hello,

I am working with 7/8" X 7/8"X 2.5" wood blocks and am having trouble putting a centerline on the block to mark for eye holes. When I drill my eye hold they are always a little off. I am using a drill press and clamps so I think the problem is me.

Part of this is due to my eye problems and part of it is me being green with woodworking.

Does anyone have any tricks or tips on getting a centerline down the length of the block?

When I finally do get one close to perfect I would like to make a jig or template out of Plexi-glass (or something) to repeat the locations.

Thanks in advance.

Dan

Heres a link to a classic centering jig, this jig is for marking center down the length of the stock: (click the image)

This is not an original idea, in fact, I am sure it has been documented on TU in the past.

Make a base plate with a pointed pin. I use 18mm ply wood and a sharpened 3mm dia brass rod for the pin. Make the plate size so that it can be comfortably clamped to the drill press plate/shelf, mine is about 8

You can use carpenter's scribes, or a drafting compass.

Set the width close to half way, pass it down one side, and then reverse the blank and do the other. If it's not dead center, the space between the two lines will be.

bisecting a line segment, middle school geometry :lol:

just draw a line across the width of your blank, and then follow this video to find the center of the blank.
