What this tool adds
What this tool adds to your bench
Choose this version when the blade needs to turn relative to the frame during intricate work. Its swiveling clamps rotate through a full circle with 45-degree stops. The maker’s manual describes using that arrangement to move the frame aside while removing waste within a dovetail.
The five-inch label describes the frame size. The Mk.IV manual specifies standard 5-1/8-inch fret or jeweler’s blades and says that coping blades will not fit. Check both blade length and the unpinned end format when buying consumables rather than using the frame’s nominal size as a replacement-blade measurement.
The selected saw has a red aluminum frame, wooden handle and cam-release tension lever with fine screw adjustment. It includes a No. 7 skip-tooth blade listed at 15 TPI. The swiveling-clamp version is distinct from the otherwise similar non-swivel model.
Compare it when repeated blade release, piercing or off-axis frame clearance are important. Choose the coping frame instead for its longer pinned blade format, or the Olson screw-adjusted frame for a different mechanism. No single maximum tension setting is prescribed here: the manual explains that blade size and installation affect appropriate adjustment.
Choose for your actual work
- Choose the swivel-clamp version when frame position interferes with the cut.
- Check the 5-1/8-inch blade standard separately from frame size.
Fit checks & limits
- No coping-blade compatibility or universal blade tension is claimed.
- Listing 9 oz and maker 228.3 g figures are not treated as one settled net weight.
- A blade alloy grade is not confirmed by the generic material field.
Use & care
Release tension before blade installation and follow the Mk.IV clamp-alignment instructions.
The maker suggests releasing tension for long storage.
Questions before you choose
Should I buy a five-inch coping blade because the frame says five inches?
No. The manual specifies 5-1/8-inch fret or jeweler’s blades and excludes coping blades. Frame size and blade standard are different measurements.
What does the swivel add for dovetail waste removal?
The maker describes turning the blade so the frame can sit off to the side while the blade follows the intended cut. Check the actual clearance at the workpiece.
Can I set every blade to the frame’s highest tension?
No universal setting is prescribed. The manual explains that blade size and installation matter, and excessive tension can break a blade.
