Tabernacle | Marking Up Bolt Holes & Rounding Edges

The next task was to drill holes for the four 8mm bolts which will secure the tabernacle to the cabin wall.

I did this by marking in the vertical centre line inside and outside the cabin, and using that as a datum line to mark in the bolt hole locations. It looked like this.

Then I drilled a small pilot hole in each location, just to check and be sure about where the bolts would go on the inside and outside cabin wall.

Here, for example, are the bottom two holes on the outside cabin wall, just above the fillet which joins it to the deck.

All looked well so I rounded the edges of the backing plate ready for installation, as here.

Bolt holes will be finally drilled when the backing plate is permanently in place.
