The Benchmaker's Apprentice: Drawbore Pins!
Well, here we are again, drilling more holes in wood. Right here I was marking the holes for where the pins go, the drawbore pins that hold the tenons in and reinforce the hold...A LOT.
Of course, the long rails use knock-down vice hardware, so I marked a hole here for the hole where the bolt inserts.
When drilling these holes, it is a good idea to throw a piece of wood in the mortise space to reduce the chance of blow-out.
So, all of our holes are done. Now all we need are some pins to fill those holes with.
Now here's something really fun! Making pins. I took a piece of ash with the straightest grain I could find and cut it up into pieces that are about 3" long and just over 3/8" square.
Using this simple jig, I took 4-5 passes with a plane on each side.
When done, the result is this octagon shape. If it a hexagon, something's wrong.
Then it's just over to the sander to get one end sanded down to a blunt point.
I just pound it straight through the pin making tool. This is a Lie-Nielsen dowel plate.
I use the next pin to push the other pin through as to not pound the hammer into the dowel plate and ruin it.
After pounding through the plate.
The final count should be sixteen for this bench. I made one or two extra for good measure, and to be politically correct.
