The most versatile chuck is a four
jaw scroll chuck. What can the Masterchuck do? Why is it better than a conventional scroll
chuck? The Supernova and Record RP4000 chucks have a flat scroll. Which is the best chuck to buy? Ordering a scroll chuck | click here

We stock various chucks and we have designed and made multi purpose woodturning
chucks for 30 years. Our Masterchuck design is a four jaw self centering chuck
with a unique patented conical scroll mechanism.
The Masterchuck will do what flat scroll chucks will do at a more economical
price. The special Masterchuck conical scroll moves the jaws into and
out of the front of the chuck at an angle. This gives a superior grip because
the tightening forces are actually closer to the gripping surfaces of the jaws.
It also means that the outer ring is smooth without jaws projecting from T slots
as in a conventional scroll chuck. The dovetail gripping surfaces on the basic
jaws (which always remain in the chuck so no dismantling is required) grip externally
or internally. Smaller or larger extension jaws can be screwed onto the fixing
holes in the basic jaws. More Masterchuck info.
This gives them a greater jaw movement than the Masterchuck so you do not have
to prepare the wood so accurately. The Record has internal 6:1 gearing and one-handed
tightening with a T bar which is a great convenience. Like the Masterchuck it
is beautifully made from quality hard wearing steel. Record
RP4000 chuck page . The Supernova chuck has now been
upgraded to the MKII with single handed T-bar operation similar to the Record
(which is, by the way, virtually identical to the Vicmarc VM100). The Supernova
MKII T bar has a ball end to the hexagon so it can be used at an angle. This
is helpful when access to the chuck is restricted.
This depends on your budget. Record and Supernova chucks are more convenient
to use but more expensive. The Masterchuck will do the job well and provides
a safe reliable grip. The outer surface of the Masterchuck does not have projections
which could rap your knuckles. Masterchuck accessory jaws are very economically
priced. All the chucks are versatile and take a wide range of accessories. The
Masterchuck and Supernova (not the Record) has thread inserts which are easy
to change, so if you upgrade your lathe to one with a different thread you can
still use your chuck. Threads available
