The metal cutting bandsaws currently in the shop (Johnson and Harbor Freight) are horizontal bandsaws, which are designed for cutting long stock into smaller pieces. For cutting metal plate into smaller pieces and for cutting curves, we need a vertical bandsaw. The Delta 14" vertical bandsaw in the wood shop is not suitable for cutting many types of metal because the blade speed is much too fast.

The cold metals area at PS1 is currently well stocked to work with materials that are already cut down to small sizes (sizes less than about 6"x6"). However, most bought materials do not come in sizes this small. The natural solution to this problem is for PS1 to invest in a vertical bandsaw.

The certification of the proposed vertical bandsaw will fall under the 'tier 1' certification process as it is a non-precision tool.

Ideally the proposed vertical bandsaw would be located in the cold metals area, if there is not space available directly in the cold metals area the vertical bandsaw would be located as close to the cold metals area as space allows.

Powermatic 143 - A 14" combination wood/metal saw with 2 speed gearbox and 4 speed belt drive. Compact and very strong for a 14" saw. $700-1300 used.

DoAll - A shop classic. They almost always have built-in blade welders, which we could use for all the bandsaws in the shop. Often 3000 pounds plus (too big), but smaller saws are available. There is a surplus of these saws on the used market, as shops are moving to wire EDM, water jet and lasers for profiling work.

Roll-In - Gravity fed sliding table. These can used as profiling or cutoff saws. Could easily replace the Harbor Freight as well as provide the sheet profiling capabilities we are looking for in a vertical. Larger footprint than a standard 14" saw, but not too heavy (~800 pounds). $750-1500+ used, $5000 new). Other companies have similar models. http://www.rollinsaw.com/band_saws/EF1459_vertical_band_saw.htm
