Title: Home made half round rasp
Post by: osage outlaw on February 11, 2014, 08:14:00 pm
This idea has been bouncing around in my head for a while now.  I wanted an aggressive half round rasp for shaping the handle/fade area.  I finally figured it all out in my mind and bought the supplies.  I ordered 10 hacksaw blades from ebay for a little over $8.  I should have got another 10 because I ended up using 17 blades.  I also bought some cheap epoxy and two end caps.  I already had the dowel rod and 1/2" copper pipe in my garage.

My supplies.  The blades are 18 tpi

I used a dremel tool to cut a slit in the pipe

I used a micro sized pair of channel locks to open the pipe up.

I cut a section off of each cap and filed them smooth.  I rounded the edges on everything so nothing pokes your hand when you use it.

A quick test fit

I hammered the pipe tightly on the sides of the dowel rod so it was a very tight fit getting the blades into it.  They were held in very tightly on a test fit.  I took them back out, coated everything inside with epoxy, and then put the blades back into the pipe.  I made sure to push the blades down on the sides so they could follow the contour of the dowel rod.  I used epoxy on the end caps and also put a small screw into them to make sure they don't come loose.

After the epoxy set up a little I tested it on a scrap of wood.  You can roll it as you push the file and get a nice rounded cut.  It does clog up a little but it is very aggressive and removes wood quickly.  I am very happy with how this turned out.  I can't wait to try it out on a bow.

That's a pretty good idea there Outlaw. It should remove material pretty quick but leave it cleaner looking than if you used an aggressive rasp. Can't wait to hear how it works.

Thanks  :)    I think I'm going to name it the Jim Duggan rasp   ;D

 I have a big full round file but it clogs up with one stroke.  Its not near as mean as this one.

Bring it to the Classic, Clint, I'd like to see it in person. Brian Melton and I have been working on the same line with diamond blades for grinding preforms for Fogging rock.

I'll bring it with me Mullet.

I think I have an old roughed out bow I can test it on tomorrow.  I wish I could cut out a new one to try it on but I'm currently without a band saw  :'(

I to like crafty things but...... Files and rasps are cheaper than what you have in this project.

My work horse handle shaper is a 10" Nicholson half round course wood file, $19 with free shipping off several sites. I used my first one from day one of my bow building in 96, put it to metal a few times( not a good idea for a wood file) and replaced it just this year with a new one that cuts like a house on fire compared to my old dull one.

Of course I have the #49 and #50 pattermakers rasps which are pretty pricey but I also have a $12 horseshoe rasp that cuts like a demon as well a brand new in the pack Nicholson wood rasp I picked up at a flea market for $2.

What I am getting at is you are better off plunking down 5 more bucks for a good file or rasp that will outlast you, if you keep it clean, oil it if you store it for a while and keep it off metal.

A good file also gives you a place to use up some of that osage scrap we generate, in the form of file handles, gotta' love them.

Eric, I have a good sized assortment of files and rasps, including some nicholson half rounds.  I wanted something more aggressive.  I spent $12 to make this.  The rest was just junk that was in my garage and a few used blades.  I have looked on amazon and ebay for an aggressive half round rasp and didn't see anything I liked.  There were some cheap ones that looked like garbage and a few expensive ones that I wouldn't pay that much for.   My files never touch metal and I store them in bike inner tube pieces so they don't bang in to each other.

By Deity! If I wasn't looking for hacksaw blades to make a rasp right before I found this thread. Of course I was going for more of a shinto knockoff, lol.

Admittedly, finding just the right file or rasp can be a daunting task. I loved my first half round course wood file and tried on a bunch of occasions to find another with no luck. I goggled just about every description I could think of for years and couldn't come up with the exact same file as the one I had. One day I added "wood" after " half round course file"  to my search and and my exact file came up on a half price sale with free shipping, DUH, don't know why I missed the wood part.

My file is an unusual file to find and not readily available, lots of look-a-likes but not the same file. I actually needed a picture ad so I could hold my old file up to the screen and zoom in to see if the teeth matched, they did.

did you reverse every other blade so it cut on both strokes?

Post by: osage outlaw on February 12, 2014, 07:29:10 pm
No Steve, I put them all facing the same direction.  While I was using it today I switched it around and pulled it for a while. 

I squared up a handle and then tried it out.  It took me a minute to figure out the best angle to hold it.
