4655 forum posts 304 photos | Hopper, the S & B model A is a very different beast from a hobby lathe like a Myford, the makers recommended 5/8" tooling, which would need shimming of about 0.100" even with a new lathe. The Atlas will be able to use the less agressive tooling. Edited By old mart on 18/06/2023 17:46:40 |

In the opening post it is mentioned about shims to get tooling on centre height. I had for a number of years used a quick change system of my own making. It was hardened and ground. With various dedicated tools for screw cutting and parting off, with about 12 toolholders proper. Keeping things clean while working on brass proved to be real problem on one job. I decided to full fill a promise to GHT and make one of his 4 tool Turrets, but with a twist. The twist is the tools are completely without packing. The top picture shows the slope on the tool bit. The centre height of the tool can be preset as the design of the tooling at that angle means the tools are on centre height with 6 mm projection from the toolholder. You will also note the toolholder completely fills the tool slot in the Turret. Keeping out bits of swarf from the mounting faces is a thing of the past. Carbide Insert tooling is also made to be on centre height. What was worked out on the Emco Maximat got used on the Compact 5 in reduced scale, but the principle is the same. The Compact 5 tooling can even be used on my Unimat 3 without alteration. Thus I have interchangeable tooling at minimal cost and across two different lathes.
