Item Name:
Blow More Glass Tools - Double-V Brass Necking Tool
SKU:
ABR-BMGT-DVNECKIGN
Description:
This double V brass necking tool is a handheld shaping tool made from brass with two V shaped forming grooves. Brass is used because it holds up to heat, warms quickly at the bench, and gives a smooth contact surface that helps move hot glass without sticking the way steel can. This tool is used in lampworking and small hot shop style forming when you need to neck in tubing, tighten a shoulder, or create a controlled constriction before pulling points, forming seals, or defining a transition.
How it is used:
Bring the glass to an even working heat, then apply the V groove to the hot section while rotating the work to keep it centered. Use light, steady pressure to neck in the diameter gradually, reheating as needed to avoid chill marks. The second V gives you another sizing option so you can choose the groove that best matches the diameter you are forming. This is especially useful for shaping necks on small vessels, tightening down before a blowout, or creating clean transitions on functional and scientific style assemblies.
