We can see that with a little thinking out of the box, different solutions are numerous.
In the 80s I bought a 36 ft.1929 Liggett from Palmer Johnson in Sturgeon Bay. It was eye candy for my tavern. A mahogany salon
step eventually became utilized elsewhere. Three steps with brackets with chrome pegs to hang onto chrome hdw with holes. Mortised headers with no risers. I used them on other boats, vans and pickups. This last summer I forgot them up against my motorhome entry whilst moving it. Alas I had five nice pieces of old weather
One day at a rest area I reconstructed with galvanized drywall screws and gorilla glue which I always carry in the rv and truck. Like brand new , well almost, structurally better actually. Pretty good stretch for 1929 steps.
On another occasion I was able to scrounge mockup plywood boxes from a maritime school
. They were used as helm
configurations. After the kids
had grown tired of playing with them I repurposed them. Boxes, no hinges , no latches
, all nailed together. They became tool boxes and shop boxes. Lasts a lot longer than cardboard. One of them found its way onto our Columbia
as a step in the vberth, it just fit there ! It doubles as a box for whatever use is needed. Some were 1/4 inch the step is 3/8 I believe. Another box holds sand paper and other abrasives. I peeled the tops off several and just added a dowel for a handle, bingo . Slapped some resin in the joints inside and out. A few have lasted 30+years .
Incidentally 1/4 can work
if you construct it with thought to continuity in structural components in multiple supports. Never say never, oops I sad it !
Youíd be surprised with some of the fine lumber used in cast off pallets. Keep it simple...
