Internal Photo Review
These are again older pictures of the original block sample sporting the old P3 split nozzle, the new nozzle tested is a single wide, but you get the general idea from the old pictures anyhow. In this photo I was fortunate to have the larger outer o-ring stay on the acrylic, that wasn’t the case when I recently changed to the P6 nozzle plate and I probably spent a good 10 minutes fighting that o-ring back into place. It might be one of those where when the block is new the o-ring is easier to install than after it’s been used for a while. My sample is a good 8 months old now.
Macro view of the channel cuts and machining finish.
Overall I thought the interior was machined with higher than average quality and tight well fitting tolerances and consistency. There are some machining tooling marks left behind from the high production cut/feed rates, but everything goes together nicely with CNC precision. I’m kind of a fan of bare copper base blocks myself as it sort of displays the natural beauty of material and there’s no worry about plating service life. My only minor complaint internally is the potential user stress test with getting the large o-ring in place, it does take some patience to put it all back together if the o-ring falls out of place. Very doable, but patience testing..:)
