Uneven progress

At the weekend, things seemed to be going slowly until I made several breakthroughs; the first was the decision add a base and then to increase the height of the base to allow the crossover to be mounted under the cabinet but not inside. That meant I could finish the wiring and not have to wire the binding post thought the inside of the cab. Aside from the last set of connectors the wiring is now finished. I also decided to glue the baffle in place which mean the mid cab had to be braced and filled from the top; which it was, and the top is now on and glued and the whole things trimmed and planed into shape. Filler was applied to the exposed pieces of particle board and the first unit is ready for sanding and painting. When I get the additional wood needed for the base I'll be able to complete that at which point the unit will be reading for measurement and testing. I'm waiting for the binding posts and terminals but, Fedx permitting, next weekend, I will be mounting the drivers.

Slow progress

The Phase IV Mk2 is proving much more complicated to build than the Mk1. Partly it's the shape, but what seems to be holding me up is sequencing. I roughed out the top and bottom and these need to be trimmed. I probably need to paint the cabinet (which will be white) before gluing in the baffle (black). I need to make sure that the crossover will fit though the woofer's hole in the baffle which means getting the mounting board for the crossover built, located and then removed again... I am still figuring out details as I go such as how to mount the crossover, how to connect it to the external links in the base that connect to the drivers. I also learned something about quality: the more linked steps there are in a manufacturing process, the more quality matters. Screwing up (for me) is almost inevitable; but it matters more when a large number of antecedent steps are wasted as a result.
