The 4-inch Exe was always supplied with a proper compound slide rest (the various 3-inch versions made do with a single swivelling tool slide for many years) but for the first two years of production no graduated micrometer dials were fitted but, when introduced (simultaneously with that on the 33/8 lathe) was in the simple, effective and large-diameter form of an engraved wheel rim fitted to the cross-feed screw only.

4英寸的可执行总是提供适当的复合幻灯片休息（各3英寸版本取得与一个单一的旋转刀架多年），但前两年没有毕业微米生产转盘拟合但是，当介绍了（同时，在3 3/ 8车床）是在简单，有效和大直径形式刻装有车轮轮辋的跨饲料螺钉只。

In 1929 some improvements were announced to what was now called the '33/8" Super Exe': the mandrel bore was increased to 1/2"(but 17/32" in reality, so allowing a 1/2" bar to pass clear through), the saddle carried a conventional compound slide rest with a T-slotted cross slide and swivelling top slide and, happily, the 10 tpi Acme-form cross feed screw had the outer flat rim of its handwheel engraved with a micrometer scale - an improvement mirrored simultaneously on the 4-inch lathe.

在1929年宣布了一些改进的话现在称为'33月8日"超级可执行'：在轴孔增加到1 / 2 "（但17/32 "在现实生活中，这样使1 / 2 "酒吧，通过明确的通过），鞍进行常规复合幻灯片其余的T型槽交叉旋转顶端幻灯片和投影片，并令人高兴的是， 10 TPI公司的Acme形式跨了饲料螺钉外单位辋其手刻有一微米尺度-改善镜像同时在4英寸车床。
