   This / these are the blades

   This is the arbor

   With cutters ( I didn't find slitting blade on arbor but same as the thick one shown here in the stack of cutters but thinner )

   This bicycle frame casting would be slit so it could close around the seat post like a clamp

   http://en.wikipedia.org/wiki/File:Stainless_lug.jpg

   It has an allen seat clamp bolt installed but appears to not have been slit yet though there is a slit on the outside of the lug. Best I could find so far.

   The pic I added shows a slit casting brazed on this frame. The slit is the slot to the right.

   Probably not what you wanted ( wood working ) but is a start.

   roc,

   Okay, my shop isn't that big.  Regardless, thanks for the links.  I am making a dulcimer (lap, Appalachian) from a kit.  First woodworking kit and first musical instrument I have ever made.  Wanted to assemble the kit so I would learn what the various parts are and how they go together. 

   The fretboard slits/slots are made with a slitting saw.  I found the blades.  Since the blades are only 3 inches in diameter I don't figure the saw needs to be bigger than my shop.  :-)

   Any ideas how, and on what, I can make those slits on future fretboards?  How does someone who is making a guitar cut those slits/slots?   .020 wide.

   Thanks again,

   Alan

   The man in the storm window shop down the alley showed me a saw he bought recently for cutting frets on dulcimers. He said it was a saw used to cut off type slugs, if I remember correctly in a print house. It has a very small narrow blade, sliding tops and lots of stops. It was about the size of an 8" table saw and an amazing piece of equipment for a very specialized function. I'll see if I can snap a picture of it, if you're interested.Peter

   P --

   I would greatly appreciate such a photo.  Are  you serious he bought it for that purpose? 

   Regardless, how many saws like that still exist?  Are you talking about the typesetting machines that newspapers used with lead?

   Also, any ideas on where he found it?  Where I could find one?

   I can help out here. The saws were called Hammond Gliders. They were very nicely engineered and massively overbuilt. Their limitations were that they had a relatively small table and the blade didn't tilt. Also the arbors were much bigger in diameter, but you can get blades with larger than standard arbor holes or have the arbor machined down. I know of at least one cabinetmaker that used one in his shop and loved it. The lead type business is now long extinct, so you will have to search for one stuck in the corner of a newspaper or older print shop's basement. You will probably be able to find them on E-bay, I suspect that they will be pricey though. Go to the OWWM.com site to learn more.John White

   Thanks John.  When I was a kid, decades ago, I worked for a small town newspaper that used the old lead slugs.  Haven't heard of anyone using them in years, if not decades.

   Pricey I don't need.  Won't be setting up a guitar or dulcimer business.  Would like to build a couple for the fun of it.

   Appreciate your time and info.

   Alan,

   The only thing I know is a metal cutting saw blade that comes in various thicknesses and tooth configurations for making narrow saw kerfs.

   Here's a link to some at MSC:

   Ah maybe you mean the slitter on a table saw

   http://www.lagunatools.com/tablesaws/tablesaw-tsws;jsessionid=0a0106521f43ee61a60fc3ae4ac1aa13ae74956906fa.e3eSc34RbhyRe34Pa38Ta3aLaNr0#

   Sorry that pic is so small. The slitter (I know it as a scoring blade ) is the small blade that prevents splintering before the large blade cuts the work. Comes on better table saws.

   Once you go to that link click on the photos button.

   Sorry roc.  Can't see them.  Thought I had an ongoing subscription to that but FWW stopped it.  Don't think I did anything wrong, but they dropped my subscription.  

   Haven't done or said anything that got me any negative or critical feedback, but they didn't answer my email about what happened.

   Thanks anyway.  I'll look elsewhere on the internet.  You have given me a lead, which I appreciate.

   For the number of fretted instruments I'll make in my life, that will probably work!  Thanks again.
