I just want to post a note as a warning to anyone considering buying this
jig in North America. It has a flaw which makes it impossible to cut proper
blind dovetails. I believe the 4250 is a rebadged version of the 4205
European model. The hardware look identical, other than one is drill powered
and one is router powered. BOTH are metric and this is the reason the 4250
is a failure. The instructions say to use a half (1/2") inch dovetail bit.
If one follows the directions you end up with a very loose dovetail
joint...useless. After combing the Wolfcraft site in Europe it is apparent
that you need to use a 12.3mm or 12mm (I'm still unclear about which because
they tell you two different things) dovetail bit for this jig to work
properly. If you convert half an inch to metric you get 12.7 mm hence the
reason this jig overcuts it's pins and tails, read -- it is anywhere from .6
to 1.4 mm out. Anyone else have similar experience. I bought this jig at
Home Depot and they don't stock the bit Wolfcraft says will work either, big
surprise, and hardware guy as Home Deport was of no help, another big
surprise. And good luck finding a metric bit in North America. As soon as I
find the box it's going back.
