Log of Alberg 30 #262 on 16 March 2016


Date: 16 March 2016 17:50 till 16 March 2016 20:00
Endpoints: Smith's Marina
Purpose: Head Raw Water Thru Hull
Complement: Yoni Bresler

  • Bought tap and die set
  • Outlined based of Groco flanged ball valve on G10 backing plate
  • Drilled 1/4" holes for three bolts to secure the flanged ball valve to the backing plate
  • Tapped the three holes for 5/16" 18 thread per inch bronze bolts
  • Taped up the thru hull and tested is against the G10 backing plate
  • Used a stone grinding attachment to gently enlarge the hole in the backing plate
  • Inserted the thru hull into the boat
  • Mixed two packets of West System epoxy with filler to about a mayonaisse consistency...should have added more filler to make it thicker
  • Battered the underside of the G10 backing plate
  • Placed the backing plate over the thru hull...epoxy oozed out the three tapped bolt holes...should have placed small circles of tape on the backside to protect the holes
  • Noticed that the backing plate was slipping down the hull a bit, slid it back into place and placed support to prevent slipping
  • After 15+ minutes the epoxy still had not kicked...left for the day
