For novice machinists learning to use a lathe, making a machinist’s hammer is a traditional project. Because the results are frequently so beautiful, the hammer becomes a lifetime favorite tool. Even those who sell machinist’s hammers are available to those who are unable to create their own:
Since I felt constructing a similar hammer would be an excellent project to use the Tormach CNC Lathe on, I made the decision to start working on some design work while I’m waiting for the lathe to arrive. I believe that Tormach’s Conversational Wizards offer the Making a hammer like this should be really simple because of the lathe’s LinuxCNC control. The “T-Hammer” is the name I’ve given the instrument (Tormach Hammer).
My design goals for the project included:
Since the Tormach lacks a tail stock, consider how to handle pieces that are longer than 3 or 4 times their diameter. aspire to make the hammer a good-looking and useful tool. Interchangeable heads are required to satisfy a variety of application requirements. Bar Stock sizes are compatible with the Tormach’s 5C Collet ᴄʟᴏsᴇR. compatible with o-rings from the store.
Making the following components is required to construct the T-Hammer: (Dark Blue) Head to be constructed out of alloy steel, such as 4130. We’ll need to build it into a real cylinder with stud holes at each end and a neck hole in the center. Threading will be required in every hole.
Red neck: fabricated from aluminum. We want a head that is heavy and a handle that is light for a better swinging sensation. Without a tailstock, we are unable to turn the entire length of the piece, but we can thread either end and achieve a good satin finish by choking up the piece in a 5C collet.
Handle (Purple): fabricated from aluminum. We will design the semi-circular grooves that O-rings are supposed to be held in place by so that we may flip this component over and spin it with a small overhang. No one will be able to tell that the piece was flipped and not turned in one operation since the line in the middle will be placed where we’re going to add an o-ring groove and will so vanish. Each tip features a lovely chamfer on one end and a threaded hole on the other. The third tip can be changed out and kept on the handle’s end.
We’ll also need some o-rings and studs, which we can acquire from McMaster-Carr or another convenient supplier, in addition to the parts we’ll turn on the lathe. I want to turn everything on the Tormach lathe, with the exception of the hole the neck screws into on the head. For that job, we’ll need a milling machine, though I imagine a drill press might work as well. Once I get the Tormach lathe and have it set up and tooled, I will discuss each item in future blogs and provide step-by-step images showing how I made the part on the Tormach lathe. Once I get going, I don’t think it will take too long.
