Needed to make a brass gas tank for my hit & miss engine and thought you guys might like some pictures. Experts might find the photo’s superfluous, but I tried to take enough that it’s a bit of a how-to post for someone newer
Lazy mans way of laying out the sheet – propped up against an angle plate, the height gauge makes quick work of the layout. Brass is .028 thou.
A lot of the corner material can be cut with good shears, but as the corners will have tabs, you need to get into them with a fret saw. Here’s the simple set up for this job
Cutting out the corner with a fret saw
The sheet is now ready for folding. Corners all cleaned out and any required touchups done with a file
Here the sheet metal is held in a home made set of folding bars – just crs, some dowel pins and cap screws.
In the midst of the first fold – I held the bars vertically as the wasn’t enough throat distance in the vice to hold horizontally – a more convenient position. Note that the tabs are not folded over at this setting of the bars
This is the right tool for folding the metal over so as to not mare the surface; a leather mallet
