The glue leather washer of 5mm has greater difficulty. If press groovy turning treatment, make rubber piece furls easily and discard as useless. The simple tool that for this we made treatment rubber gasket (1) seeing a picture, introduce as follows now: The car makes rod of wooden strong core 7, the biggest diameter should be more than 160mm, clamp is in chuck 1 on. rubber piece 2 cut below (the diameter is more than 150mm) , place in arbor end panel, with pushpin 3, 6 fixed, cannot have knit, also cannot tighten too, what reoccupy has had is plastic board 4(diameter is 76mm) , with tailstock tip 5 support a bit close. Turning rotate speed is optional decide 1200r/min, wait for movement cutting of smooth and junior travel, the attention walks along a knife not to pass fast, with small procrastinate board feed is better. The useless compound center that uses Ø1mm is gotten in lathe tool of wear of the blade on emery wheel, horn of point of a knife is 7 ° of 5 ° ～ and R1.

5(sees graph 2) , after been grind, must be in a poor light with oilstone knife face comes Ra0.

8, make sure blade of cutting tool cutting is sharp. After lathe tool blade is ground, the installing hole D that puts arbor is in (arbor head 20 × 40, flank getting has one via D, knife handle 20 × 20) , tighten solid lathe tool with bolt. 1.
