It never had a handle when I inherited it.
Stanley Bailey No. 4 1/2.
So I'm having a go making one outta wood.

Now, have a look at this photo...

Note the threaded rods. I'm convinced the threaded ends started with a larger diameter?
Or is it my eyes?
I tried adding extra thread to mine - but the die (1/4NC20) - just 'falls', once past the thread.
If that makes sense.
The rod is in poor condition.
