More Tests with the new Version of the Sprycalkheat wit 750ml Cans and 0.3mm Nozzel-

First pictures of the Spraycalkhead in Version 0.2



Spray chalk head the first run

After some back and forth now the first attempts with the Spraycalk Head on the Sand and Spraycalk Machine.

Not so nice is the consumption of spray, 2 doses for the first try is not just so cheap.

But ... the mechanics and the quick-change system work excellently.

The thing with the consumption we will tackle with larger can (750 ml instead of 400 ml, which also fit into the receptacle) and a modified nozzle 0.3 instead of about 0.6 mm.

We are good things that this works well

And really ... the under-floor lighting is not really cool
