Tubeless Inflator - broken garden sprayer bodge

So I was looking to get something like an air shot to #give-tubeless-a-chance again after a couple of failed attempts.
I was idly looking on YouTube the other day and came across 'Skills with Phil' channel where he used a garden sprayer as a compressor.
I realised I had a broken one in the garage.
The spray nozzle and valve were broken and not salvageable though.
So I replaced that with a 1/4 turn ball valve.

Pumped to 3bar and gave it a go:


Tyre pope's quite nicely even without soaping the bead. Topped up to 40psi with track pump and all good.
Just need to add sealant now.

So saved myself £40 and reused something I was going to dump - bargain!
