Chloroform
Would it be possible to use HCL instead of a hypochlorite to oxidise acetone into CHCl3?
(didn't seem to fit into the Garage experiments column)

I don't think so.
Me thinks that using HCl will just protonate the carbonyl and will react with water to give you some acetals, perhaps! Cl- is a poor nucleophile and
so it won't attack.
...but maybe I'm wrong!...

No, it won't make chloroform.
However I've been in your boat, I went down a path involving trying to make chloroform from acetone and HCl. Eventually I realized that there
was no reaction that was evident so I figured that it might help if I oxidized the HCl, so I mixed equal volumes of HCl with H2O2 30% and finally an
equal volume of acetone, I got a reaction but no chloroform  . Just goes to show
you a little knowledge can be much more dangerous then none.

The hypochlorite is required for the replacement of the 3 H's on the terminal carbon by chlorine. HCl has chloride ions, which would be useless
for the replacement of the H atoms. Cl<sup>-</sup> is a moderate nucleophile, but it can't replace H<sup>-</sup> since
the latter is a very strong base.
Some alternatives:
I<sub>2</sub> + NaOH to make iodoform
Cl<sub>2</sub> + NaOH to make HOCl in situ, and chloroform.

Acetone and HCl will give you a mixture of compounds, Diacetone alcohol and mesityl oxide will be among them (possibly mesitylene too, if you leave it
long enough).
The haloform reaction only works under alkaline conditions.

doesn't HCl and acetone give phorone? or is that only under certain conditions?

It does give phorone, but only under certain conditions. See the DPPP thread for more details on phorone.

Acetone and conc HCl should undergo acid-catalysed aldol condensation, too, to give mesityl oxide, shouldn't it?
