Welding with Shielding Gas

1/31/2021

0 Comments

 
We have shielding gas for the welder now. It welds much more cleanly. Here are some knob positions that seem to work well. Be sure to open the gas valve on the top of the cylinder before use, and close it after. Leave the pressure-setting knob where it is. Run the exhaust fan when using gas.

I hooked up the leads wrong at first. See the welds in the middle below. The nicer welds on the sides are after we changed the leads.

Metal Casting Furnace work

8/11/2020

0 Comments

 
We are making great progress on our metal casting furnace. We plan to cast aluminum and maybe brass. The furnace is built from an old propane tank lined with refractory. A weed torch will heat it. Wires are welded into the lid to support the refractory. Cardboard tubes and soup cans create vent holes. We used an old paint can as the form to make space for the crucible.
Our original furnace was charcoal fired and it was a nuisance. We also made our own refractory, greensand, and crucible. This time, we bought those items. Much easier!

3D Printer Filament Storage

7/9/2020

0 Comments

 
PLA filament absorbs moisture from the air and becomes brittle, or so I'm told. I know the black filament has been left out for several years and breaks under its own weight.

We now have a cooler with Desiccant! ​The desiccant is the orange stuff in the tub on the left. The instructions to recharge it are on the blue bag behind the tub. It is supposed to turn green when it is saturated. You can recharge it in the makerspace microwave or take it home and put it in the oven.

Please keep the filament in the cooler with the lid closed. Might as well keep the ABS in there as well.

Soap Box Derby Racer

The race isn't until April 2021, but we did some more work. The rear axle bearing are here. Next is to cut holes to bolt them on and to thread the 3/4 inch axle ends. 
We also removed the old counter and opened the roll-up door to give us more space

Sewing a Boat Cover

7/6/2020

0 Comments

 
I needed a boat cover for my 14 ft Sunfish, so I decided to make one. The old, blue sewing machine in the craft corner did a great job. It only does straight stitches, but went through the double layers of Sunbrella with no problems. My newer sewing machine at home didn't work so well!

Threading the machine is a little different, so here are some photos.
