The finished result seems to be fine for my purposes.

Despite reading some negative comments about modifying the hexagonal heads of set screws and bolts, I set about producing my tee-slot bolts from some 'Carriage Bolts' (aka 'Coach Bolts') bought at my local 'pound' shop. It is surely relevant to any lathe, although the specifics given here are for my Myfold ML10. _ max.I needed some tee-slot bolts to fit my lathe.

When ordering or requesting a quote, please take a few minutes to complete the following data sheet. Once the 'M' collett has been hand-turned so that it's snug on top of the hydraulic portion of the HKZ cylinder, the hydraulic pump must be turned off and all line pressure going to the clamps must be at zero psi in order for the units to be hydraulically independent and mechanically fail safe. lf using the 'M'-Type Mechanical Lock-Collett one needs to turn down the collett on every clamped HKZ unit after the hydraulic circuit has been activated.Make certain that the clamp is down to within 1/16' or less of the die shoe surface before activating the hydraulic pump and clamping the HKZ unit. Pre-clamp by hand screwing the unit down as far as possible while still allowing free access to the hydraulic port located at the front of the clamp.Make certain that the die shoe surface is free of debris and lubricants. Push clamp and T-bolt assembly forward (toward die) as far as possible to ensure proper sealing.Unscrew clamp sufficiently so that it easily passes over the die shoe.Clean off any debris or chips that may be in the T-slot or on the die shoe surface. Visually inspect clamp and T-bolt-for obvious defects.Technical Data Operating Procedures: To Clamp

Can be used with existing or specially hardened T-bolts.

Self-locking in clamped position with the Mechanical Lock-Collett option.

Available with or without Mechanical Lock-Collett Clamps at any position along the length of the T-bolt
