DIY Brunton 70P Deck Compass Mount for a Delta 17 Kayak

The Delta 17 Touring Kayak does not currently come with a recess for mounting a deck compass.

However, the  day hatch is ideally positioned for a deck compass and a second hatch lid can be ordered from Delta for mounting the Brunton 70P marine compass. Cost ~ $80 

1. With an adjustable hole saw, cut a 2 3/4 inch hole in the center of the hatch lid
2. With a semicircular file, gradually increase the diameter of the opening until the brass ring of the cuppola just fits through
3. Trace the perimeter of the compass faceplate and cut a 1/16 inch thick rubber gasket with a 2 3/4 inch diameter hole in the center
4. Mark the 4 faceplate holes on the day hatch and the rubber gasket and drill with a #40 bit
5. Fit a 1/8 x 2 3/4 inch I.D. O-ring between the faceplate and the rubber gasket to create a waterproof seal
6. Use 1/2 inch stainless steel (non-magnetic) #4/40 machine bolts with washer, spring washer and nut to secure the faceplate, O-ring, rubber gasket, cuppola and the brass backing plate to the day hatch lid
7. Run tap water over the compass and check the underside of the day hatch lid to test for water tightness — tighten as required 
8. Mark the kayak deck center-line with tape and align the lubber lines
9. Similarly, mark the magnetic deviation of your area and rotate the day hatch lid to compensate
