One of the hamsters that turn the wheel inside has died. Remove the brushes and blow out his remains. While doing that put in new brushes. For a coolant running bandsaw you need one made for that. There are no tires, just steel wheels. HF makes a good 7X12 that has coolant flow. It is a good tool to have in the shop, especially for cutting thick solid things.. I have cut 7" round stock in it many times. It lists at $900, but regularly goes on sale for much less. Also, check and see if you can use the 25% off coupons on it.
