DDO Black Hole Bigger Than Expected

Not a DDO construction update. Cygnus X-1, the first X-ray source accepted to be a black hole, is bigger than expected. Possibly the biggest astronomical claim to fame for the giant telescope of the David Dunlap Observatory is its role in the first observations confirming Cygnus X-1 as a black hole. We haven’t checked lately to see...

Update on the DDO Restoration

New paint job on the dome Ylab’s home at the DDO has been undergoing an extensive restoration since the spring. As scaffolding is starting to come down,  it’s looking amazing. The work has been extensive. Removing all the old lead paint without getting it in the environment. Carefully restoring all the windows to their original...

Tool warranty honored. Finally.

We’ve had  post or two about problems with certain MasterCraft tools. We also posted about it on facebook where Canadian Tire responded, asked us for contact info, and then… crickets. So just to show that I’m not just a whining complainer… I’ve had a Craftsman ratchet for… decades. Let’s not give...

Another fix-it night. Sorry, Crappy Tire.

We left that post with a pretty crappy picture. Protective plastic was still covering it.  Test usage showed an area for improvement. Sliding everything into place would work better...

Here once again is our picture of a pair of side-cutters that broke simply doing what side-cutters are supposed to do. Reminds us of the old mechanic’s joke about there being two types of tools – Snap-On...

Ylab Final Fall Update: New materials. New possibilities.

Persistence pays off. For our last bit of catching up on what’s been happening over the last few months, we get to show off some of the new materials ylab members have introduced to our maker space at the David Dunlap Observatory. The laser cutter is always the touchiest thing. Before any new material goes on there, we look into the safety...

Fix-It Night for Crappy Tire Stuff

We have a bunch tools at ylab, and some of them from Crappy Tire. We can call them that – after all, Canadian Tire fought for the use of that name. You would normally think we would be using their tools to fix other things. Nope. We had to fix the tools. This  Mastercraft drill is about 4 years old, the first 3 1/2 years being unused...
