1.Bowl


We started with a piece of flat square aluminium sheet. I drew an inscribed circle on it and cut it out, which is the foundation of the bowl. Then I drew the center of the circle and several concentric circles according to it, so that I can aim easily.

Then I strike the outer side of the circle to make it wrinkle up using the wooden mode and the pointed side of hammer, like everyone else did. It was so much more harder then I thought. The first few strikes were fine, but my hands got more and more sour and the hand holding the metal down hurt by the vibration while striking. What to do next is striking the wrinkles down using the rounder side of hammer and make it concave into the mode. Then repeat this movement for hundreds of times, until the metal sheet has a rough bowl shape.
Next step is using this mushroom shape mode to define the unflatten detail of the bowl using the small flat-headed iron hammer tapping gently and constantly. The metal started to be more and more like a hemispherical bowl.

It's time to use English Wheel to roll the roughness out. I chose a most round wheel and swiped the bowl between the two wheels. Then I rolled the bowl at every angel for nearly an hour, taking it out to check every 10 minutes.
The final step is using the rasp board to make the bowl edge flat and unsharp.
This is the result. First time to be a ironsmith. I can feel the difficulty, but I'm liking it.

Aluminium Bowl Making Tutorial

Things You Need Aluminium Sheet Hammers E nglish Wheel STEP 1 Use guillotine to cut your big aluminium sheet into a square piece about 25cm*25cm size. STEP 2 Draw a inscribed circle on the square metal sheet. Use this kind of scissor to cut the shaded part off. Tips: use a right handed scissor is you are right handed, vice versa. And make the blade nearly parallel to the metal. It will make the cutting easier. STEP 3 Draw the round metal sheet like this ( central point and concentric circles). Then strike every jointed point on a template like or a sandbag using the pointed side of the rubber hammer showed above. The flat sheet start to have wrinkles curved up. Be careful don't make the wrinkles too crushed, it will be really hard to make it flat again. STEP 4 Then use the more rounded side of the hammer to strike the wrinkle down evenly around the circle. This will make the bowl more sunken. STEP 5 Put it on a mushroom shaped ...

Assignment 2--Ferrari 250 GTO

My Group Members: QIUTONG ZHANG RUILIN QIN QIAN SHA ZHENLEI YU SHANSHAN ZHANG & JIAYU LI (me) Like every group else, we started with making the template by laser cutting every pieces that compose the Ferrari.   We all practiced how to use laser cut this time, from original files to AI files that adapt laser cutting machine. But for the first time we didn't chose the right thickness of material, so we did it again. This is how it looks like after we put every pieces together.  We made the distance between two pieces pretty small and have more pieces, in order to get a more fluent shape of the car when we shape the metal. Then we used masking tape wrapped it for the same reason. Then we divided the car into several parts:  top of the car(from empennage to windscreen), top cover,  the front face, right front above wheel, right back above wheel, left front above wheel and left back above wheel. Then we used tracing paper to get ...

3. Tray

My partner and  I picked a piece of timber then use the bandsaw and sanding machine to make us a templet. The timber templet (forgot to take photo right after I made it, this is the one I took while I was doing the tray, but you can still get the shape of what we made, which is a rectangle base with 4 rounded corner) We placed the templet right in the centre of the sheet, and used the flat hammer to strike 4 edges folded 90 degrees.  Be careful of the 4 corners, they were really hard to make. Once you strike one side down, the other side will raise up. This step needs patience. Just strike gently and evenly on every spot it will become the shape you wanted. After I have done the rudiment, I took the tray and templet off the clap. It was a bit un-flat on the base. I put it on the sand bag and hit on the templet to make it flat again. This is basically what it looks like.  Because we were using the same templet, my partner Shanshan's tray an...
