Direct Answer: Cut The Kerf Coupon Before The Lampshade Panel
Cut a TYVOK X1S 2026 slot-together lampshade kerf coupon before the full panel cut.
Why Slot-Together Lampshades Need Fit Testing
Laser project communities repeatedly discuss kerf fit for slot-together assemblies; a coupon prevents a full panel from becoming scrap.
Coupon Sizes To Include In The Test
- Cut a small coupon with three slot widths around the expected material thickness.
- Test the actual lampshade tab shape, not only a straight rectangle.
- Assemble two crossing pieces and shake them lightly before approving the full panel.
Lampshade Kerf Decision Table
| Check | Passing Evidence | Rework Signal |
|---|---|---|
| Slot width | slides together with light hand pressure | requires forcing or falls apart |
| Material thickness | coupon uses same sheet and finish | coupon uses a different scrap |
| Tab shape | rounded or angled tabs are included | only square slots are tested |
| Assembly feel | joint holds after handling | joint loosens after one movement |

Buyer Questions About Kerf Coupons
Why not cut the full lampshade first?
A full panel wastes time and material if the slot fit is wrong; the coupon catches that cheaply.
How many slot sizes should I test?
Three is usually enough for a first pass: expected size, slightly tighter, and slightly looser.
Should finish be applied before testing?
Yes if finish will be applied before assembly because it can change joint feel.
What should be written on the coupon?
Write material thickness, file date, slot size, and whether the fit was tight, slip, or approved.
