Been on this forum a while however haven't done much with my lathe and mill.
I have a line trimmer, however the grass had grown so long that I decided to try fit a steel blade for it.
Made the attachment shown out of 50mm diameter aluminium bar.
It threads onto a M8 thread protruding from the base of the cutter. Holes are drilled to allow me to use a angle grinder wrench to tighten. A lock-nut secures it further.
Major issues is that my workshop is a mess, this greatly increased the time needed to find tools. Will be trying to tidy and organise it more.
Had to find somewhere that sells 6.8mm drill bits to allow the taping, 6.5mm wasn't good enough. Cut up fingers trying to hold outside of part whilst tapping, so learnt to use a clamp for this.
The opposite side of the fitment (not shown) has a stalk that fits in the hole for the blade to centre it. The stalk is 1.9mm long whilst the store bought blade is 2.0mm thick, such that the stalk doesn't transmit axial loads onto the blade. There is then a small cavity such that only the outside few millimetres of the fitment contacts the blade to transfer rotational forces (torque) to the blade.
Have tried use it and so far so good.
