Been busy wax oiling the rear arms of my car this morning. T'other day I adapted a cheap spray gun, or so I thought, with a bit of flexible pipe and radial jets, to blow the wax into the rear arm enclosed sections. One of those with the red plastic bottle, a trigger, and a long rigid lance. It was so old, the alloy lance had rotted, so I just put the flexible pipe on the inner pipe, thinking the venturi was in the handle - it wasn't, it was where the inner and outer tubes came together at the tip of the lance - doh. So it just blew air out, when the trigger was squeezed, no wax.
I swapped all that, for a conventional paint spray gun, which worked fine for the accessible bits of the rear arms, but a bit of a compromise for inside the box sections.
Got a phone call from a doctor, from a local university hospital, asking me if I would mind to volunteering to take part in some heart experiment, for those with kidney failure. He wanted to send an email, explaining what was involved, I asked it be sent via the post, and having read it, I was a bit wary, and quite concerned, so I expressed my concerns in an emailed reply. He rang again yesterday, to allay my concerns about the process, basically a stress test on my heart, whilst in a MRI scanner, so I agreed to it, and a date quickly arranged.
