15/03/2008 - Playing with Alodine

A lot of builders have cut up the wooden box that brings the spars and longerons as storage in their workshop; however I didn't have room for storage lol.  However next door managed to reuse them as tomato planters in their greenhouse...brilliant.

Anyway on with the building.  I still have not finished all the wing access nut plates on one of the spars; so I quickly did that and then Callum (my son) helped with Alodining with Alocrom 1200 all the countersunk holes on all the spars.  It was during this process that I noticed that the holes newly countersunk turned an iridescent gold similar to the spars whilst ones that have been done a few days ago went a burnt gold.  I decided that this as down to dirt and resolved next time to clean or Allocrom soon after the countersinking phase.

Calling it a day for today and will proceed next with putting nut plates on the web part of the spars as per the instructions.
