DIY tool holders.

These are a few tool holders I made years ago. A few tangential and a few standard type with various rakes. The tangentials don't get used a lot as they have their limitations in respect of access to the job. The standard type holders I made get a hammering.

They're all made from sections of 16mm Square bar welded together at various angles. Slots for the tool were cut with an endmill on the lathe using a vertical slide.

I made them with all sorts of angles to see which was best. After several years use, it doesn't really matter, they all work well.

Looks to me like you had LOTS of fun! I love playing games like that too.

Once I realized how the metal is actually "cut" everything started to make more sense. It isn't really "cut", it's more like "plowed".

I lost all interest in tangential tools once I came to know that their real advantage was easier tool grinding and an overall increase in system rigidity. Carbide inserts do all that and much more. On top of that, indexable HSS inserts do exist and carbide inserts for aluminium actually have sharp edges.

I have insert holders as well, rarely use them. If I can use HSS, that's my choice,

Nice work, I would never guess they were welded and done on the lathe and not a mill.
You must have been on quite the tangent back then.
