ワックス彫刻＆クラウンゲージ — スプリングキャリパー、ステンレス鋼、1～10mm範囲

The spring action is smooth enough that I can check a margin thickness one-handed without the jaws slipping. Readings line up with my digital gauge, which is what I wanted for the 1–10 mm range. Nice to finally stop guessing on wax walls.

Checked a full arch of wax patterns with these and the 1–10 mm range covered everything from thin crowns to bulky bridges. The stainless steel hasn't rusted or stiffened up after a few months of daily use. Zero guesswork on wall thickness now, my castings have been coming out clean.

The spring action on these is smooth enough that I can check thickness one-handed while the wax is still warm. Stainless steel wipes clean easily and the 1-10 mm range covers everything I cast. No more guessing whether a margin is too thin.
