band saws

Watch CL for a used HF Hor/Vert. They really do work well with a little tuning and are a step up from a porta-band in my opinion. usually can be had for ~$100. Just make sure it is the model with rotary adjustment for the blade alignment. Mine didn't have that and was a challenge to get a straight cut.
Another option is to contact SpeedyMetals. they will cut to any size A x B you want for no extra fee on multiples. There will be shipping involved unless you have a location near you, but it might be worth it depending on how many parts you have.
