DIY Steel Bench Vise: Build It from Scrap Materials 2026

The bench vise is one of the most common and indispensable work tools. Here's how to build one from scratch using leftovers from other projects, with only an angle grinder, a MIG welder, and a drill.

Designing a DIY Bench Vise

Having various scrap iron and steel pieces on hand, our reader Aureo Graca Machado decided to build a DIY bench vise for his projects: a similar commercial model would undoubtedly cost more than most hobbyist vises. Designing a DIY bench vise of this type is less simple than it seems: each component must be sized and connected to others to ensure resistance to various forces, but our reader seems well-versed in the subject and comfortable with MIG welding.

For your own home improvement projects, having the right tools and materials can make all the difference.

How to Build a Bench Vise

Step 1 – Gather the Materials

All parts of the vise are made from recovered material. The handle is made from a Ø16×240 mm stainless steel rod with 20 mm nuts at the ends; the same nuts are used for the lead screw head, which is a Ø20×340 mm threaded bar.

Step 2 – Prepare the Base Plate

To give you an idea of the proportions, the bench mounting plate is made from a 210x110x8 mm plate with two 30 mm deep and 20 mm wide pieces removed from the front corners. The jaws and the sleeve on which the movable jaw is fixed are made from 60×60 mm tubing.

For your workspace, consider adding a sturdy work surface or a storage bench to keep everything organized.

Step 3 – Weld and Assemble

Using your angle grinder and MIG welder, cut and weld the components together. Ensure the movable jaw slides smoothly in the sleeve and that the lead screw turns freely. A good work light is essential for precision welding and assembly.

Tips for Buying a Bench Vise

If DIY isn't your style, there are excellent commercial options available. Look for a vise with a strong clamping force, durable steel construction, and a swivel base for versatility. Check out home improvement collections for ready-made vises and other workshop essentials.

For your workshop, don't forget comfortable seating and floor protection to create a safe and productive environment.

Frequently Asked Questions

What materials do I need to build a DIY bench vise?

You'll need scrap steel or iron pieces, a threaded rod for the lead screw, nuts for the handle, and basic tools like an angle grinder, MIG welder, and drill.

How much does it cost to build a bench vise from scrap?

If you have scrap material on hand, the cost can be very low—just the consumables for cutting and welding. Commercial vises can range from $30 to several hundred dollars depending on size and quality.

Can I build a bench vise without welding?

Welding is highly recommended for strength, but some designs use bolted connections. However, for heavy-duty use, welding provides the necessary rigidity and durability.

What is the best size for a DIY bench vise?

For most hobbyist work, a 4-inch to 6-inch jaw width is ideal. The vise in this project uses 60×60 mm tubing, which gives a jaw width of about 60 mm (2.4 inches), suitable for lighter tasks.

Where can I buy a bench vise if I don't want to DIY?

You can find quality bench vises at hardware stores or online. For a wide selection, check out home improvement collections. Also consider a shed or greenhouse for dedicated workshop space.
