How to drill a hole in a hardened steel blade ?
The build is on hold while we go back and fix something that was a failure.
Next thing to try is drilling both the jigsaw blade and the offcut and screw together to clamp the scroll saw blade.
This will be a interesting session as we are going to mount the saw arm bearings and install the assembly onto the saw frame.
With the arm support column dismantled I marked out the bearing centres on the two supports in preparation to bore the bearing mount holes.
Still waiting for the chooks to go to bed so I can put their food away and lock up, so may as well prep for tomorrow.
Bought a few more items from Bunnings yesterday so I could move on with the scroll saw build - today.
Starting to take shape 
At this point right here, with a scroll saw blade mounted in the inverted jigsaw, I can now measure, cut and mount the main saw arm.

This is just a overview of what I've been doing in the workshop over the last few days…and nights. I built the 8" bandsaw last year and since then have not been happy with the design of the upper wheel block blade tension and blade alignment components. Adjusting one effects the other, increasing tension jams up the tracking adjustment…plus other stuff. Basically that design was flawed so I am building a scaled down assembly very similar to the 14" bandsaw that I built earlier this year.
This is the upper wheel block blade tension and tracking assembly. It does work but to hard to setup up so I'm going to pull out the whole thing and start again.
