Board center gauge
This is a gauge I have seen boat builders use to mark center on both sides of boards when splitting them in half.
The grooves will serve as a guide or the saw cut.
After making one in wood, I wanted one to match my hardwood and brass gauges.
(This was made February 2011, just never posted).
As always we start with the materials.
Ohhh yes and some good tobacco.
Cut up some wood, I made some extra in pine for gifts.
Also extra wood dowels.
Now finding the right size drill bit.
So here you see my original wood version and the brass rods cut to size.
I had to reshape the drill bit, so it would cut less deep in the center.
See the difference.
Mark up really carefully.
Center and each side.
Then pre drill holes.
Holes for the rods.
Made a little mess here…
Cut up some threaded rod and put in the dowel.
Glue in place.
Here you can see the markings.
Time to drill the center hole.
I put in a threaded insert.
Like this I can use a kurled brass bolt.
Cut it to size and drill a hole in the center.
I use a piece of a drill bit.
Cut it off.
Epoxy it in place.
Shape it pointed by running it in a cordless drill against a dish sander.
Shaping the gauge.
Oil, wax and al that jazz.
We got a gauge!
This is how you use it.
Flip and check you did right.
(If you id it will still be in center).
Now the pin can be lowered if wanted.
Back to work MaFe.
Perhaps it can inspire to split some boards.
