Blimey. Where does time go?
After the cladding on the left cabin was complete, I started on the railings which would run around the veranda, across the bridge and around the part of the right tower.
The railing posts used 4" x 3" either screwed through the cladding (with a spacer to allow air flow) or were 1/2 lapped and fastened to the base of the veranda as shown. An M8 coach fastened these in situ. Deck board cut in half along the length was used for rails at the top and bottom between the posts, and I would fasten spindles (of a fashion) to these.
Along the top of the posts, a hand rail made from 4" x 2" with the end edges chamfered to save little hands from injury. The hand rails being fastened from below through the rails between the posts.
For the spindles, I used 2" x 2" cut to length. The spacing was approximately 2 to 1, but then adjusted so there would be equal gaps, ensuring the centre of the middle spindle was in the centre between the posts. Where there was no support under the spindles on the front of the veranda, I chamfered the edges to help with water run off, and to look good, I hope
The railings across the bridge were done in almost an identical fashion, but for posts, using 2" x 4" because I was using standard deck railing for the handrails. The top of the 2" x 4" posts and 2" x 2" spindles needed trimming slightly to fit in the underside (dado?) of the railing
Please excuse the grass, I can only do one thing at once!
