Workshop alignment tools promise accurate spindle positioning and reliable edge finding for milling and drilling. Clear marks and concentric setups reduce mistakes and wasted material for both trade professionals and serious hobbyists. Is the Tyzack Wiggler & Centre Finder Set the right addition to your workshop kit?
⚡ At a Glance
- • Alignment Accuracy: Needle point stops oscillation when centred, while ball and disc contacts locate edges and hole centres precisely
- • Best for: Machinists, metalworkers and workshop hobbyists who set up spindles and need precise edge and hole location
- • Not ideal for: Users who require electronic probing or automated CNC probing systems for alignment
Five-piece set includes a wiggler chuck with push-fit attachments for centre, ball, disc contacts and a DTI holder. Used to align the spindle over scribed lines or punch marks and to check concentricity of holes and fixtures.
Faster spindle alignment - thanks to the needle point centre finder
Needle point attachment is brought close to a scribed line or centre punch and the oscillation of the point stops when the spindle is directly over the mark. Attachments push-fit into a collet in the wiggler chuck that mounts in the machine spindle.
Quicker, repeatable set-ups reduce time spent aligning workpieces and lower the chance of mis-drilling.
Accurate edge and hole location - with ball and disc contacts
Ball contact rides along an edge until it kicks out, locating the centre a distance equal to half the ball diameter; the disc contact presents a flat face for finer edge detection. Sizes given in descriptions indicate typical diameters used for offset calculation.
Reliable offsets for machining from edges or existing holes make setting origins and fixtures straightforward.
Concentricity checks made simple - with the offset indicator holder for a DTI
Offset indicator holder adapts a Dial Test Indicator so it can be swept across holes, mandrels or mounted parts to measure run-out and true alignment. The holder fixes into the same push-fit system used by other attachments.
Fast verification of run-out and vise alignment helps catch setup errors before cutting commences.
✨ The 4 Key Reasons for Tyzack Wiggler & Centre Finder Set
- Push-fit chuck and collet - enables rapid attachment swaps for quicker machine set-up
- Needle point centre finder - locates centre marks by stopping oscillation when aligned
- Ball contact (0.25" dia) - determines hole centres and offset precisely from edges
- DTI offset adapter - allows sweeping for concentricity checks to reduce scrap and rework

❓ Frequently Asked Questions
Q: How is the set mounted in a machine?
A: The wiggler chuck/holder is mounted in the machine spindle and the attachments push-fit into a collet in the body.
Q: How does the needle point centre finder indicate alignment?
A: Bring the needle point close to a scribed line or centre punch; when the spindle is centred the point appears to stop wiggling or oscillating.
Q: Can I check concentricity with the set?
A: Yes, the offset indicator holder accepts a Dial Test Indicator so users can sweep and check concentricity of holes, mandrels or a vise on the machine table.
🏆 Our Verdict
The Tyzack Wiggler & Centre Finder Set is suited to machinists and workshop hobbyists who need reliable, manual spindle alignment and precise edge or hole location. The combination of push-fit attachments for needle, ball and disc contacts plus a DTI holder makes setup, offsetting and concentricity checks straightforward. While simple in design, the set represents a practical, long-lasting workshop tool for anyone who frequently sets up spindles and fixtures.
