Actually electric scroll saws aren't ridiculously expensive these days and don't require as much dexterity. They have a much larger throat too. Of course the panel needs to be flat(ish) in order to manoeuvrer it across the table. A typical example: EDIT: The better ones have cast tables rather than sheet. |

Only electric ones. :) A good designer/engineer would cut all the holes first and then do the bending. I, on the other hand, first do the bending and folding and then the cutting holes. So manual saw it is. In any case, aluminum cuts like butter and I have carved out holes just with a knife. If it is a one time thing and you have time you can do anything with aluminum. It is only slightly harder than wood :) Some years ago I was given a Mini-ITX board but I had no case so I built one. I remember it took me forever and wondering if it was worth it. That case and computer have given me many years of service. OTOH, I have made things that I soon discarded and thought it had not been worth the trouble. |

When I was younger I would remember and retain what I learned. Now I tend to forget it. Maybe I will put a label on my fret saw. :) |
