I'm planning to make a riser plate so I can use a Tripan 111 toolpost on my newly acquired Hardinge HLV-H. I'm looking for suggestions on materials and machining / heat treating.
The Tripan is a small high quality Swiss made quick change toolpost commonly seen on Schaublin lathes.
I've determined that 5/16" of riser plate puts the Tripan 111 where it needs to be. I was planning on making the plate from ground flat stock. The question is: What grade to use.
In the past I've used Starrett 498 low carbon as for its machinability. However, this riser plate needs to work with a hardened tool post. Of course, the compound slide it will rest on is not hardened (assuming it is high quality cast iron).
I'm thinking I can get the plate water-jet cut, so that machinability is less of an issue. I'll trim the edges on my mill to clean them up afterward.
Ideally I'd prefer to make something that does not need to be sent out to be hardened, but I won't rule that out if that's the best way to go.
BTW: I make mostly small precision parts and take light cuts. The compactness of the Tripan 111 is an advantage and I won't be using more than 0.5 HP of spindle power so I'm well within the range for that post. For bigger jobs I have larger toolposts that I will be able to swap to.
Thanks in advance!
