Jointapprentice Hobby a1 and kerfed linings - Ritmos sureños de Bolivia (Paul Paulino López)

A surrealistic - meditative journey along a kerfed lining.

If your meditation is good, after some time you will hear beautiful music arranged and played by the Bolivian musician Paúl Paulino López, recorded in Zürich on his 2001 Swiss concert tour with William Ernesto Centellas. More info on this at http://www.centellas.com

The manual table saw is a shop made copy of the patented and pricey Jointmaker Pro v2 from Bridge City Tool Works (hence my saw's nickname "Jointapprentice Hobby a1 - where "a" stands for "attempt). No commercialization of the original Jointmaker idea allowed until patent expires (which will be the case in 20 to 25 years after patenting). More info on the original at http://www.bridgecitytools.com/default/tools/jointmaker/jmp-v2-jointmaker-pro...

The patent features some good drawings of the original Jointmaker. Unfortunately I discovered them too late, I gathered all the information from the Jointmaker videos on You Tube.
Here is the patent with it's drawings: ( http://tinyurl.com/5wg2276 )

My own, home made version is mainly made of MDF and plywood, the "heart" of the tool is a Japanese sawblade which does the perfect kerf for the frets on an instrument's fingerboard (my thanks for this hint go to Pete Howlett, http://petehowlettukulele.co.uk ), while the "lung" of the tool are two pairs of drawer slides (those cheapos with the flimsy linear ball bearings).

The capabilities of the my copy does not include combined mitre cuts (unless very tiny ones if you make a jig for this task) and it's cuts are limited to a maximum height of aproximately 23 - 32 millimetres (this depends on the blade's rising angle) compared to ca. 40 mm on the original. Workpieces can be up to 73 mm deep, when cheating (= not using the whole blade) up to ca. 170 mm. Maximum cutting height at one stroke (with very soft woods only) is 12 mm.

The gizmo for feeding the lining I made after an idea I have from the Italian world class luthier Luca Waldner ( http://www.lucawaldner.com ), back in the times when he had the guts to run an own Internet forum and had some really useful hints online.

You can find details and lot's of pictures about the building process on the ANZLF (Australian New Zealand Luthiers Forum, http://www.anzlf.com/viewtopic.php?f=24&t=3128 )

Any questions about the saw or the music and the musician are welcome.

Any intelligent comments are welcome.

Keep all stupid comments for yourself unless you are a well respected ANZLF member.

Thanks for watching, listening, reading and your patience!

@hasslefactory Oh, so you've got the SW! Congrats! I think its certainly worth it's money if you have heaps of fun using it. There exist less intelligent ways to get rid of hard earned money!

Thanks again for your compliments! My saw is a bit less complex than the bridgecity version though: I cant tilt the blade of my shop-brewed saw. This has mainly to do with the building material: opposed to aluminum, my MDF-composites take much more space which blows dimensions up like a balloon.

@charangohabsburg Thanks for the reply! I'm a newbie woodworker determined to (someday) make fine miniatures and boxes. One of the first tools I bought was the SW version of the JMPv2 (essentially the same saw, but only one sliding table). $500 less than its big brother, but still a shockingly huge investment for me. I feel very fortunate to own it, and I just wanted to say that my familiarity with the complexities of this saw just makes me admire your shop-built version all the more. Amazing.

@hasslefactory THANKS! The name is an intentional malapropism of "Jointmaker Pro v2" which a similar saw made made of aluminum, available from bridgecitytools,com for the neglectable sum of 1300.- USD. My MDF copy cost about the same if I calculated 10 $ per hour, but my calculations go the other way round: every hour I enjoyed building the saw I did not spend money on some leisure activity! :-) You can see pictures of the building process on ANZLF,com (forum), search for "JointApprentice" ;-)

Wow - NICE job building your "JointApprentice Hobby a1"! Hilarious name, by the way. And (as a newbie woodworker someone just starting to explore kerf bending) I really REALLY REALLY love that gadget you've built for advancing the work. Thanks so much for posting this.
