U Bat System Description
The universal bat system is designed to allow the potter to throwon a removable bat insert without removing the main body of thebat from the wheel head. This gives the potter the ability toproduce multiple pieces in a shorter period of time. This system alsosaves storage space in the studio, when compared to spacerequirements for the same number of full sized bats. The heart ofthe system is a 13 Medex bat with a machined pocket cut into it.This pocket receives the 5 1/2 square inserts. The inserts are removed by lifting a corner of theinsert. Two machined finger slots at opposite corners of the pocket allow for finger access.Fitting the Inserts in the Pocket The final fit of the inserts is determined by the users personal preference. The inserts are made froma material called Medex which absorbs moisture and changes the dimensions of the insert. The insertsare cut to fit the pocket with very little side to side play. This may be too tight for some users. If thisis a concern, the insert may be downsized by simply sanding the insert on each of the sides. Too muchside to side play may cause stability problems when you are throwing, so reduce the insert size slowly.Do occasional fit checks while you are sanding. Sand each side of the insert equally. It is suggested thata fit check be made with each insert before you start throwing. Check the fit again after using theinsert several times.The pocket in the bat is cut slightly deeper than the thickness of the bat insert, (1/32-1/16 of an inchdeeper). This allows for expansion of the insert due to water absorption during the settling in period.In the mean time, you may raise the insert by placing several balls of clay in the pocket before youinstall the insert. Press down on the insert to level-off the insert with the bat body. Slight protrusionsor recessions of the insert can be expected. After using the bat system several times, the wood material will settle in, meaning that minimalchange will occur with the dimensions of the inserts due to water absorption. Also, the insertthickness/pocket depth differences should have diminished.
Using the U Bat System
Place the main body of the bat on your wheel head. The bat pin holes have been drilled for theconventional center to center dimension of 10 inches. Place one of the fitted inserts in the pocket and throw as you would on any other bat. Remove yourpiece when finished, sponge any debris away from the pocket area and place another insert in thepocket. Warped inserts can usually be flattened by drying them in astack with heavy weight on them.
