Produced dimensioned CAD models and manufacturing drawings from existing physical
components in SolidWorks, reconstructing geometry, tolerances, and GD&T callouts for
legacy parts lacking documentation; drawings were released to production and used to
manufacture parts.
Designed and deployed the shop’s production quality-control system, replacing a
paper-based inspection workflow with enforced dimensional verification that hard-stops a
job when a reading falls out of spec, staging inspection from casting to first-article to
QA-approved-to-ship with blind re-measurement; used daily by 6 machinists across
~10 work orders per day.
Operated manual lathes independently across the full job scope, interpreting
drawings, planning operation sequence, selecting tooling and speeds/feeds, and performing
in-process dimensional inspection to hold specified tolerances.
Manufactured precision components on CNC mills and lathes, frequently operating
2–3 machines concurrently and holding tolerances as tight as ±0.001 in.;
proposed revised CAD designs of existing components to improve manufacturability and reduce
machining operations.
Bemco makes rolls for steel mills, and the sleeved roll is their own design. A solid roll wears
out where the impact lands. So the roll gets split into a hub carrying one or two sleeves. A worn
sleeve is reversed to use its unworn side, and the two sleeves can be swapped. Two sleeves with two
usable sides each is four times the life of a solid roll.
I built scaled training versions of the full two-sleeve assembly. First I modelled the hub,
sleeves and ring in SolidWorks. Then I drew them with section views and chamfer callouts, machined
the parts on manual and CNC lathes, and put them together to check the fit.

From Part to Drawing
Dimensional inspection · SolidWorks · GD&T
A lot of the parts we made had no drawings. They were legacy components, and the only record of
the geometry was the part itself. So I measured them and rebuilt them in SolidWorks, geometry,
tolerances and GD&T callouts. Those drawings went to the floor and parts were machined from
them. That is the part I would point to. If I got a dimension wrong, somebody was going to cut it
wrong.
Each pair below is the same component.

Manufacturing
Machining from Drawings
Manual and CNC lathe · Tolerances to ±0.001 in.
By the second summer I was running manual lathes on my own across the full job. That means
reading the drawing, planning the operation sequence, choosing tooling and speeds and feeds, and
inspecting in process to hold the tolerance. Nobody was setting it up for me.

Quality engineering
Production Quality Control System
In daily use by 6 machinists · ~10 work orders per day · Shop-floor tablets
Bemco machines rolls and roll components to tight drawing tolerances. However, the problem I
kept noticing wasn't on any machine. Every inspection was recorded on paper, and a measurement
only got checked if someone remembered to check it. So I built the system that replaced it. Six
machinists use it daily on shop-floor tablets.
The workflow
The office opens a work order with the customer, drawing number, casting
count, and the dimensions and tolerances for every operation. On the floor, each casting is
screened proceed or not proceed before any machining time goes into it. Operators then log their
actual measurements against each dimension, and every reading is checked against the tolerance as
it is typed.
Three controls are enforced, not encouraged.
Each one is a rule the system applies. None of them depend on somebody remembering.

1 / 4
1 · Inspector check. The run stays locked after part one until a second person blindly re-measures it
An operator cannot inspect their own work. The system recognises who took the original readings and refuses the check.Blind re-measurement. The inspector sees the dimension and tolerance but not the operator’s reading.
1 / 2
2 · Non-conformance hold. An out-of-tolerance reading stops the operation
Caught on entry. A reading outside the band is flagged before it is committed.Hard stop. The operator must request an office override, which is approved or rejected and recorded.

3 · Sampling before shipment. And the record the customer receives
10% of parts, minimum one, randomly selected. A failure escalates the whole lot to 100% inspection.Inspection Report. Every part by name and timestamp, the inspector’s column beside the operator’s, each part traceable to its heat number.Write-once for operators, fully editable and printable by the office, giving a traceable history per part.

Retaining Wall
Layout · Excavation · Drainage · Material selection
I designed and built a retaining wall sized to stop falling trees. The base excavation was set
off the wall height, the gravel drainage layer runs to mid-height with a drain pipe to relieve
water pressure behind it, and every second course is set back so the wall resists tipping.
