When purchasing v-nails, there are a few things to consider:
- Your specific machine requirements
- The material that your molding is made from
- The thickness of your molding
Different machines use different types of v-nails. There are two main types:
- Universal Stick V-nails have a width of 10.2 mm. They are used in the Inmes IM-3P, IM-4P and IM-5P and in our FS 1000 and FS 2000 underpinners.
Machine Specific V-nails are different and cannot be interchanged with universal v-nails. These v-nails are designed for the specific machine or brand of machines in which they are used. Brands that feature machine specific v-nails include:
- Cartridge V-nails are v-nails enclosed in a plastic cartridge for use in specific underpinners. Inmes IM-2 underpinners use this type of v-nail.
V-nails come in both softwood and hardwood types.
The type of molding material you are using will determine which type of v-nail you should use.
Softwoods such as poplar, pine and cedar generally have a more open grain and require a sharper v-nail to join the molding.
- You would also use softwood v-nails for plastic/polystyrene frame molding.
Hardwoods such as oak, ash, hickory, cherry, maple and walnut have a tighter grain and require a more blunt v-nail to join the molding.
- You would also use hardwood v-nails for moldings made from MDF.
Using the incorrect type of v-nail for the material you are joining could result in split molding.
You will find it is much easier to join your frame molding when you are using the correct type of v-nail
V-nails also come in different sizes; 5mm, 7mm, 10mm, 12mm and 15mm.
The corresponding sizes in imperial measurements are 3/16", 1/4", 3/8", 1/2" and 5/8".
This size refers to the length of the v-nail, not the width.
Use the depth of your molding to determine which size v-nail you should use.
Ideally, v-nails should cover about 70% of the depth of your molding.
