My new Dovetail Saw made from an old Disston 68 saw with a gent style handle and firewood (silky oak). 

This is my submission for the r/woodworking Reddit Firewood Challenge (I also made a small chisel, marking knife, and handle/tote for a hand plane while I was at it - see below)

I found a place selling firewood and had to check it out. It was a woodworkers paradise! At least it was for me since I like to make smaller items and don't use long boards often. They had all kinds of stuff there (olive wood, burls, figured stuff, wormy wood, etc). I think different landscaping and tree removal services dump the trees they cut down there. 

I spent a good thirty plus minutes climbing on top the mounds of wood in my work clothes and looking through what was there. Needless to say, the worker thought I was pretty strange. I made a pile and asked how much. He said $5. I ended up picking up some more pieces since it was so cheap.

I ended up choosing this piece for my project because I wanted something with long straight grain to keep the handle stable. I think it's silky oak

I cut it down to size on my bandsaw

I cleaned it up on the jointer

I glued on my template from Blackburntools and drilled some holes

Here is a picture after drilling. 

I roughed it out on the bandsaw

After some shaping with a sander, I used the saw to cut the slot

This part was difficult since initially I didn't have a small enough chisel. The picture is actually my second attempt since I messed up the first one and had to start over. I made a small chisel out of a drill bit and scraps from the same firewood piece. With this smaller chisel, I was able to properly size the slot for the back.

I picked up a Disston 68 from a garage sale a couple weeks ago for less than $5 and wanted to make a pistol grip style handle.

I cut off the old handle with a hacksaw

I grinded the back off with a belt sander

Sharpened the teeth

Picked up some brass bolts from Home Depot and sanded the round tops flat so it didn't look like random bolts I bought from Home Depot

Then I chiseled out the recesses on the back for the nuts to sit in.

Test fit: I was worried it wouldn't fit right but after some fiddling it fit!

This is after LOTS of filing and sanding. Did I mention  I sanded a LOT?

Applied the finish (Danish Oil and Paste Wax)

Here is a marking knife and small chisel I made from the same wood

I found an old reciprocating saw blade

Threw a chunk of the wood on my lathe to make a new knob for my cheap Stanley hand plane to replace the plastic one.

Turned it round.

Here is a pen I turned a little while back (prior to the firewood challenge start) from the same wood.
