The plastic tubing can be purchased at hardware stores, by the foot,?and?even at pet stores. ??In the Fish tank section you will find aquarium pump air hose material. That¡¯s what you need. You just need to make sure to measure the treadle belt groove?to make sure you purchase the correct diameter.??If you¡¯re interested in trying the tubing,?do a search here in the messages for further information. Or do a Google search.?
