Designing the tapered balusters for this job was a process of working from an original image sent by the customer to what we have here. The first image below is the original sent by the home owner.
The first drawing I made was elongated to make them modern code ready. The originals were apparently too short for todays height standard.
In the second iteration, the homeowner asked me to make the balusters pin tops instead of the square top balusters. The top bead was eliminated as well. The baluster shank, though was “barrel” shaped. That is, the main part of the baluster was cylindrical with a short taper near the top.
In the final design, the balusters are strictly tapered to a one inch “pin”. Normally a 1 3/4″ pin top baluster has a 3/4″ pin top. These, however, have a 1″ pin top. The thicker 1″ pin enabled us to use two balusters per tread instead of three balusters per tread. With a ten inch deep tread we were able to maintain a maximum 4 inches between the balusters.
