Kerfs

Kerf notes

Short editorial notes on flanges, score height, humidity, and handoffs.

Photograph the first board

Before you open rate, shoot the first board with the kerf in frame.

2026-08-14 | Mr Retief Nieuwoudt

Riving knife before lunch

A knife that drifted overnight is scrap by 10:00.

2026-08-18 | Ms Mmathabo Mabuza

Highveld dust on flanges

Dust on the flange face reads as runout. Wipe before torque.

2026-08-20 | Mr Yeshlan Singh

Coastal humidity and plastic

KZN acrylic softens mid-afternoon. Feed slower after 14:00.

2026-08-22 | Ms Masego Ngwenya

Score height on laminate

Score just through the face paper, not into the core.

2026-08-25 | Mr Ayanda Baloyi

Thin kerf on thick hardwood

Thin kerf is not a shortcut for dense hardwood rips.

2026-08-28 | Ms Mmathabo Mabuza

Label every bore reducer

Mixed saws, mixed bores. Labels beat guesswork.

2026-09-01 | Ms Masego Ngwenya

Melamine chip on the exit

Exit chip means the wrong grind or a dull set.

2026-09-03 | Mr Yeshlan Singh

Soft jaws on aluminium

Clamp soft or you mark the extrusion before the cut.

2026-09-05 | Mr Retief Nieuwoudt

Load-shedding and hot blades

Power returns, blade still hot. Wait before a precision rip.

2026-09-07 | Mr Ayanda Baloyi

Dado arbor length check

Measure arbor stick-out before you stack the set.

2026-09-08 | Ms Zulfa Salie

Wet cut on porcelain

Dry continuous rim on porcelain is a crack waiting.

2026-09-09 | Ms Mmathabo Mabuza

Flange torque sequence

Star pattern, not a single hard yank.

2026-09-10 | Ms Masego Ngwenya

Account for kerf waste

Nest lists that ignore kerf width fail on the last sheet.

2026-09-11 | Mr Retief Nieuwoudt

Hang blades, do not stack

Teeth into foam, not into the next disc.

2026-09-12 | Ms Zulfa Salie

Peel film after the cut

Cutting through protective film can drag and chip.

2026-09-13 | Mr Ayanda Baloyi

OSB dust on site saws

Site OSB fills thin-kerf gullets fast. Clean mid-pack.

2026-09-14 | Ms Masego Ngwenya

Heat on PVC edgeband

Flush trim too hot melts the band edge.

2026-09-15 | Ms Zulfa Salie

Showroom demo card

One blade, one material, one photo. Not a circus.

2026-09-16 | Mr Yeshlan Singh

Export crate blade packs

Foam, labels, and a care card inside every crate.

2026-09-17 | Mr Retief Nieuwoudt

Morning warm-up rip

Three scrap rips before the first client blank.

2026-09-18 | Mr Yeshlan Singh

Negative rake feed feel

Let the tooth work. Pushing aluminium bends stock.

2026-09-19 | Ms Mmathabo Mabuza

Cleaning card cadence

Resin build-up is not a new blade problem.

2026-09-20 | Mr Ayanda Baloyi

Handoff note for the next shift

Write which blade is on the arbor before you leave.

Kerf checks before first cut

A note can be checked against your saw, blade diameter or material stack through our contact form.
