Mixing the 4:1 perlite:refractory cement
The core planters and the base in place.

What it looks like inside with the core out. It’s still _really_ soft.
Yet another busy afternoon; I mixed up some perlite/refractory and started building out a furnace for aluminum casting. Things are going pretty well so far. The 4:1 perlite to refractory mix seems to work OK, although I am sticking closer to 3:1 right now. My refractory cement already has some aggregate in it, so it’s a bit intolerant of the big chunks of perlite. I wish I could add some soap to the mix to make the perlite wet out better.
I also picked up a propane adaptor for a barbecue which just happens to match the size of a cheapass propane torch. This means I can use my cheap propane nozzle to heat the assembly. Turns out that there are standards for these kinds of things. Who knew!
Next up, drilling holes for handles in my cast iron skillet/crucible, then burnout for both the furnace and my 3d printed investment, then finally a test casting in Aluminum. Gonna be a busy week.
Finally started to brew again after a hiatus of several years (due to time constraints, not by choice).
The new high output burner. It’s like a jet fighter taking off.

Just added the final aroma hops

This time around I am brewing a 7-ish percent IPA, using ESB and Caravienne malts, and a ludicrous amount of hops. I hope the 1.120 starting gravity will balance out the massive IBU.
Just switched to a more “standard” heated bed, and a JHead to replace my long suffering makergear extruder.
I cannot believe it has been nearly two years since I built this printer!
I have added some updates to Reticulatus which vastly improve the OpenGL display window. Now I am ready to start adding slicing tools to the UI.
Python based 3d printer slicers need to be faster: rantenki/reticulatus.
It should be noted that this
has no interface, no gui, not cmdline, and cannot yet be used for slicing unless you call the libraries directly from python.
That is all.
Finished setting up for Maker Faire tomorrow. So tie tie!
We cut the tigerwood for the clock last night, here’s a photo of the three pieces together:
Went to Greendale Pottery and Beef yesterday to pick up a quarter of a cow. You heard me. A quarter of a freakin’ cow.
What? It’s Barbecue season?
Anyway, as I’m sure you’ve gathered from the name, she also makes amazing pottery. Check out our new pottery beer mugs. Looks like a beer poured into a clear glass and running down the edges but it’s just the glaze colour.
ps. Maker Faire on Saturday! Don’t forget to buy tickets!
