Two summers on the floor at Bemco Machine Works, a steel mill roll manufacturer in Mississauga.
I produced CAD models and manufacturing drawings that were released to production, machined
precision components on manual and CNC lathes, and designed the production quality-control
system now used daily by six machinists.
Bemco manufactures rolls for the steel mill industry and originated the sleeved roll design.
A solid roll wears out where the impact lands, so Bemco redesigns it as a hub carrying one or
two sleeves. A worn sleeve can be reversed to use its unworn side, and the two sleeves can be
swapped — two sleeves with two usable sides each gives four times the service life
of a solid roll.
I built scaled training versions of the full two-sleeve assembly: modelled the hub, sleeves and
ring in SolidWorks, produced dimensioned drawings with section views and chamfer callouts,
machined the parts on manual and CNC lathes, and assembled them to check fit.

Many of the parts we made had no drawings. They were legacy components, and the only record of
the geometry was the part itself. I measured them and rebuilt them in SolidWorks — geometry,
tolerances and GD&T callouts. Those drawings were released to production and parts were
machined from them.
Rebuilt from measured parts
Working from supplied drawings on manual and CNC lathes: reading the drawing, planning the
operation sequence, selecting tooling and speeds and feeds, and inspecting in-process to hold
the specified tolerances — as tight as ±0.001 in.

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. Inspection was tracked on
paper, where a measurement only got verified if someone remembered to verify it. I designed and
built the system that replaced it.
The office issues a work order carrying 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 is spent on it. Operators then record actual measurements
against each dimension, checked against tolerance as they are entered.
Office to floor
Three controls are enforced, not encouraged.
Each one is a rule the software applies rather than a step someone has to remember.
1 · Inspector check — the run stays locked until a second person verifies part one, blind
2 · Non-conformance hold — an out-of-spec reading stops the operation
3 · Sampling before shipment — and the record the customer receives
Built on React, Cloudflare Pages, Workers, D1 and R2, with PIN authentication, role-based
permissions and device-level access control for shop-floor kiosks. Screens shown use
demonstration data.

Retaining Wall
Layout · Excavation · Drainage · Material selection
Designed and built a retaining wall sized to block falling trees. Base excavation proportioned
to wall height, a gravel drainage layer to mid-height with drain pipe to relieve
hydrostatic pressure — the usual failure mode for a wall this size — and a
setback every two courses to resist overturning.

Shoulder Motion Simulator Actuator
Supervised by Dr. Louis Ferreira · SolidWorks · Team project
Developed and evaluated five linear actuator concepts, including a magnetic linear actuator, using weighted decision matrices comparing force output, response time and manufacturability
Targets: 140 N force under 1 kg system mass, with precise multi-axis tendon actuation under dynamic loading
Produced detailed engineering drawings with tolerances, section views and assemblies
Final selection was rack-and-pinion, chosen on feasibility and manufacturability
