Master Kit: 903-71300-0000
Our X-Blocks are engineered to solve a problem every fabricator runs into constantly: no two setups are ever the same. Traditional 1-2-3 blocks and V-blocks are single-purpose — one shape, one job. X-Blocks are a modular positioning and workholding system, CNC-machined from billet aluminum, that interlock and stack into whatever configuration the part in front of you actually needs.
Each block in the system is machined to interface with every other block — the Large X-Block, the Rectangle Blocks, and the Triangle "Y" Blocks all combine on a shared geometry, so a hand rest today becomes a deep-V tube cradle tomorrow, using the exact same set of parts. This is what makes X-Blocks a system, not a set: the value compounds every time you find a new combination.
Beyond part positioning, X-Blocks are built around a principle most workholding tools ignore: operator comfort directly affects weld quality. A stable hand or elbow rest reduces fatigue over a long session, which shows up as steadier torch control and more consistent bead placement from the first weld to the last. For production motorsport welders, this also means repeatable setup — build the same block configuration for the same job, every time, and get the same result. X-Blocks are designed to complement your existing fixture table, not replace it, dropping into your current workflow through the Large X-Block's integrated table interface.
The Large X-Block's underside is machined for threaded fixture pins and magnetic retention, giving it fast, secure indexing on standard fixture tables or a direct magnetic hold on any ferrous steel top. Set it, lock it, weld — no dedicated fixturing required for most setups.
The two Triangle "Y" Blocks are purpose-cut so that a pair, placed point to point, forms a deep-V cradle for round tube — ideal for header and roll cage work — or can be used individually to hold a part at a controlled angle for out-of-position access.
X-Blocks are machined from aircraft-grade aluminum and built to the same standard as the rest of the TIG Aesthetics lineup: a tool you buy once and run for the rest of your career, not a shop consumable. Buy it once, use it on every job for the next 20 years.
Key Features
- CNC-machined from billet aluminum for precision fit and long-term durability
- Fully modular — every block interfaces with every other block in the system
- Threaded pin holes + integrated magnets on the Large X-Block for fast, secure fixture-table mounting
- Triangle "Y" Blocks pair to form a deep-V cradle for round tube, or work individually for angled positioning
- Reduces operator fatigue through stable hand/elbow rest points — supports steadier torch control on long welds
- Repeatable, indexed setups for production environments where consistency matters run to run
- Complements existing fixture tables rather than replacing them

Ideal Applications
- Custom fabrication and one-off tube/chassis work
- Production motorsport welding where repeatable setup matters
- Hand and elbow support during long TIG sessions to reduce fatigue
- Deep-V tube cradling for header, exhaust, and roll cage fit-up
- Angled part positioning for out-of-position access
- Magnetic or pinned mounting to any ferrous fixture table
Built for fabricators who never build the same part twice — and for production shops that need to build the same setup every time — X-Blocks deliver a modular workholding system that adapts to the job instead of making the job adapt to it.
