+/-0.025mmTypical tol.
A newel post is primarily made by Turning (Lathe). Turning spins the workpiece on a lathe while a single-point tool removes material, producing round features to tight tolerance. Below is the full route to make a newel post, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a newel post is made
The usual route, raw material to finished part. The amber step is where the newel post gets its basic shape.
Stock
Start from bar, plate or billet sized for the newel post.
Turning (Lathe) (roughing)
Rough out the main shape, leaving stock on the critical surfaces.
Tooling None Tolerance ±0.025 to 0.125mm Lead 1 to 10 days
Finish machining
Take the finishing passes that bring the newel post to tolerance.
Tooling None Tolerance ±0.025 to 0.125mm Lead 1 to 10 days
Holes and features
Drill, ream and tap, and where needed broach splines or cut gear teeth.
Tooling None Tolerance ±0.05 to 0.2mm Lead hours to days
Heat treatment
Harden and temper if the newel post must resist wear or load, then finish-grind.
Tooling n/a Tolerance can distort Lead days
Grinding
Where the newel post has bearing or sealing surfaces, grind them to the tightest tolerance and finish.
Tooling Low (wheel) Tolerance ±0.002 to 0.02mm Lead days
Surface finish
Anodise, plate or coat for wear and corrosion resistance.
Tooling Low Tolerance adds microns Lead days
Inspection
Measure the newel post against the drawing, on a CMM for close work.

Cost
What a newel post should cost
Round parts (shafts, pins, fittings); priced by spindle time. Low setup, usable from qty 1.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a newel post at your volume, in your currency, are in the dossier.
