A Simple Keyway Cheat
| An attempt, albeit with some hiccups along the way, to achieve a keyway when no options for milling or having a shaper to do the job. Not the prettiest of methods but it can work - and also if needed, a similar approach can be used to cut an internal keyway in a bore -- this would require a boring bar with a suitable tool insert. Despite some problems, the hope is that it shows what can be done if no other way available to achieve the result. This only applies to a straight cut keyway. Fabrication and use of a purpose-ground tool is going to make this process easier, and the result can actually be tidier than what is shown!. Bear in mind, the stresses on the lathe doing this, and, we should have drilled a run-out hole, of course! |
