Chloroform from TCCA instead if hypochlorite?
Can TCCA be used as the chlorinating agent instead of sodium hypochlorite to make chloroform? Could it be used directly, or would one need to use it
indirectly to generate chlorine? Would the chlorine need to be bubbled through sodium hydroxide to get hypochlorite or is it feasible that the
chlorine could work directly on the acetone?

You should try using the search engine, there are a few posts concerning this, even somewhere a successful description how to do it.
Apparently you use the TCCA to generate a hypochlorite solution in situ, somehow like this.

I found this thread the other day, which includes a method for doing what you are after I think.

Not too long ago I calculated the cost of this, using TCCA + NaOH + acetone to yield chloroform using reported yields. I didn't save the calculation
but it was something like 2-3 times more expensive (per unit of chloroform produced) than using gallon jugs of 10% pool chemical bleach.

I did look at a few existing threads, but it didn't seem like any consensus was reached.
I suppose you mean the one where NaOH and acetone is mixed, and chlorine bubbled through it. Someone warned against polymerisation happening with the
acetone so it didn't seem like an entirely good method.

Sure, I believe you. But I don't have the option to buy gallon jugs of pool bleach unfortunately. The only chlorine I can find is cleaning grade
chlorine, which is sometimes full of detergent as well, plus it's ~2-3 USD per liter. Plus, I already have a whole lot of TCCA that I probably won't
be using up any time soon. And this alternate route is an opportunity to learn more chemistry.
I'm also not too stoked about the sheer volumes required when using hypochlorite.

I didn't realise the link wasn't working in my last post sorry.
Did you see the work by garage chemist and woelen?
