I think I mentioned this elsewhere, but i've been planning for a while to make some videos about chemistry. I'm going to start it all off with a fume hood, since that's what I can build with my current tools. The plan so far. It's going to be on wheels so I can push it about. A couple days ago I cut up two big boards of plywood into the various panels that will make up the thing. It's a task I was dreading but was glad to get out of the way. Wood is perhaps not the ideal material for something like this, but it's relatively cheap and easy to work with. I am planning to make a sort of steel tray for the inside at least, to somewhat prevent fires damaging the wood. Today I got some time to nail the bottom half together. I'm going to attach the wheels to it before I start assembling the upper half. I've also been trying out some of that polyurethane construction adhesive and it really gets everywhere. |

You could have used a old cabinet or Ikea it probably would have been cheaper. |

Not sure if it would've been cheaper either. And i'd need this to be stronger than Ikea's chipboard and cam fastener construction. |

True I was just wondering it seems a lot of things are produced way cheaper than the cost of materials. I've never liked chipboard! |

Got some more done. Bit of a delay since I got caught up helping prepare for a funeral. Put the wheels on a couple days ago. For the windows on the side of the thing I routed them. It's not easy to see in any of the pictures, but I routed a ledge on as well for the glass to fit in. For the second window I realised it's better to route the ledge first before going all the way through. Also I didn't have material to make a proper template, so I ended up making a single corner piece and moved it around as I reached each corner. Getting the top half on was a real fiddle. I started by nailing and gluing the top to the sides on the floor, and then lifted that up onto the base. Then glued and nailed the back on to get it all square and rigid. I feel like theres probably a smarter way to assemble stuff like this but it's beyond me. Take note of my dumb jacket. The next step will be front bits. So as for the jacket. I've gotten the silly idea of trying to make my 'show' more interesting (for the viewer and myself!) by giving it a scifi theme, in the form of 'skits' at the midway point and how any diagrams I draw look. Honestly I just want a chance to make props and effects, but I think it could help offset how dry the topics might be otherwise. |
