It can accept a bolt of up to 20mm and has holes for two 6mm pins that can be put into the T-nut to prevent the splined cylinder from rotating on the compound. At it’s core is a hardened and ground splined cylinder 75mm in diameter. What’s different this time: The Multifix E is about the biggest toolpost you’d want to put on a HLV-H.

I think it might be because of the longer unthreaded section fitting tightly against the bore I made in the “T bushing”. The bolt for the Tripan fits tighter and does not rotate at all even with no pressure being applied. The design is similar to the bolt for the KDK 0 but uses a M10 x 1.5 bolt and has a cylindrical projection to fit into the bore at the bottom of the Tripan and locates the 5/16” riser plate that compensates for the difference in center height between the HLV-H and the Schaublin so that I can swap toolholders between the two machines. Tripan are small and very precise toolposts commonly used on Schaublin lathes (my other lathe is a Schaublin 102N). On the right is the bolt I made for my Tripan 111 toolpost, again made from a bar of C1215. The pressure of the bolt being pulled upwards into the “T” part keeps it from rotating. It is made from C1215 steel and has a flat head (countersunk) 3/8-16 bolt that inserts from below. In the middle is the bolt I made for my KDK Series 0 toolpost. It is partially threaded so the bolt cannot go through the nut and contact the bottom of the T-slot. It appears to be stainless, and hase a 7/16 - 14 thread. On the left is the T-nut I got with the KDK Series 100 toolpost, likely made by the shop that previously owned the HLV-H.

Perhaps it a description problem with people using different terms to describe “hold down bolt”. I tried advanced search and literally got nothing.

Just want to know if I’m doing things the right way and if anyone has any suggestions. I haven’t had any problems with the bolts I’ve made but I wanted to tap into the vast knowledge base here. This new one is going to be for a Multifix E toolpost. I’m about to make my third toolpost hold-down bolt for my Hardinge HLV-H in less than a year.
