An original educational poster identifies 5 documented features of this one-piece tool. The numbered descriptions remain readable below the artwork on narrow screens.
- Flattened foot
Broad contact patch bears on the work or a protective pad.
- Horizontal arm
Provides reach between the bench hole and the foot.
- Formed elbow
Continuous bend joins the arm to the vertical post.
- Vertical post
Fits a 3/4-inch bench hole and wedges under a mallet tap.
- Foot contact detail
Magnified view shows the same flattened steel foot.
Technical references: Gramercy Tools holdfast official product and use. The maker describes this holdfast as one cold-formed steel piece. The study magnifies the elbow and foot; those views are details of the same intact tool, not removed components. Original educational artwork depicts the intact tool and magnified features; the additional views are not detachable parts.
02 / Understand the tool
What it is and what each part does
The Gramercy Tools holdfast is one continuous cold-formed steel piece, not a threaded clamp or a forged multi-part assembly. Its 3/4-inch post fits a suitable bench hole; a mallet tap at the arm sets it, and a tap at the side of the stem releases it. It is fast for planing stops and bench-top workholding when the bench thickness and hole fit suit the maker's instructions.
The post enters the bench hole with a little clearance. A tap flexes the arm and cants the post so it grips opposing sides of the hole. The flattened foot bears on the work. The maker specifies a bench at least 1 3/4 inches thick and a 3/4-inch hole; fit, reach and wood condition matter. The anatomy poster shows an intact tool with magnified elbow and foot views, not removable components.
Formed elbow and arm
The continuous bend and horizontal reach spring under a mallet tap; there is no hinge or screw to adjust.
Flattened foot
The broad end transfers pressure to the work; use a pad when its steel face could mark a finished surface.

02 / Working principle
Set, guide and control the action
These decisions make the mechanism useful at the bench.
Check hole and bench
Use a 3/4-inch hole in a sound bench meeting the maker's thickness minimum. Test fit before clamping valuable work.
Set with one tap
Seat the foot on the work and strike the arm near the bend using a suitable mallet; increase force only as needed.
Release at the stem
Tap the side of the upright near the bench to free the wedge; support the work first.
Bench-top planing
Pin a board against a stop while leaving much of its upper face clear.
Carving and shaping
Secure a broad workpiece without a clamp bar crossing the active area.
Temporary fixture
Hold a batten or auxiliary fence on a suitable bench when its foot has a safe purchase.
03 / At the bench
Setup, technique and finish quality
Use the steps for a first pass, then inspect the work before changing the setup.
- Inspect the post, foot, mallet and bench hole; clear chips and test the fit.
- Lay the work on the bench with a protective pad if the steel foot could bruise it.
- Insert the post into a suitable 3/4-inch hole and place the foot on solid stock.
- Tap the arm near the bend until the work is secure; do not overstrike.
- Test that the work cannot move in the planned direction before cutting.
- Support the work, tap the side of the post to release, and lift the holdfast out.
Grip comes from wedging
The post cants and bears against the bench hole; a loose or too-short hole may fail to hold.
One piece, several features
The foot and elbow close-ups are the same continuous tool, not exploded pieces.
Surface pressure is local
Place the foot over supported stock and pad delicate work to avoid a dent.
What changes by model or material
This reference is cold-formed wire steel. Forged holdfasts from other makers can differ in spring and reach.
Hole diameter, thickness and wear change holding. Follow the selected maker's fit guidance.
Leather or wood pads spread force but require retesting grip and clearance.
Choosing the tool
- Check the required hole size, bench thickness and reach against your bench.
- Inspect smooth post and foot surfaces and a continuous undamaged bend.
- Choose a mallet and protective pads suited to the work.
Useful accessories
- Suitable mallet
- Leather or wood foot pad
- Bench dogs and planing stop
Consumables
- Optional protective pads
- Fine abrasive for maker-approved scuffing if a slippery post fails to grip
04 / Keep control
Care, troubleshooting and safety
Secure the work, protect sharp edges and release any stored clamping pressure before adjustment or maintenance.
Care checklist
- Wipe the steel dry after use.
- Remove rust or resin without changing the post diameter.
- Inspect the bend and flattened foot for cracks or deformation.
- Store dry where the projecting foot cannot catch clothing.
Common mistakes
- Using a bench hole that is oversized, too shallow or damaged.
- Striking the foot or bending the arm with excessive force.
- Clamping fragile stock without a pad.
- Assuming a failed grip can be fixed by ever-harder strikes.
Safety at the operation
- Keep hands away from the strike zone and under the foot.
- Test holding strength before planing, carving or drilling.
- Wear eye protection while striking steel with a suitable mallet.
- Support the work before releasing the post.
When the result goes wrong
Check hole diameter and bench thickness; clean the hole and consider the maker's light post-scuffing guidance.
Use a clean leather or wood pad and position the foot over solid support.
Support the work and tap the side of the stem as the maker describes; avoid levering against the bench.
