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.

8) Idea Clint really 8)

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.
-
As the old saying goes " necessity is the mother of invention". Great idea!
-
I'm with Bill, very cool rasp Clint.
Tracy
-
That's a good idea Clint! Thanks for sharing :)
-
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.
-
Brilliant Clint, very creative and I see where it would be useful.
Jon
-
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 :'(
-
Its amazing what the imagination unfolds when it comes to hand made tools. 8)
-
Nice Clint. I like that
-
Cool Clint. I'd like to see it too. 8)
-
That is a very clever idea. Looks great.
-
I don't want to wait till the Classic, so bring it to Moontree in March. :laugh:
-
Will do ;)
-
Pretty cool Clint. You are definitely an inventor. Shoulda posted it in the build-along. Like always, you never cease to amaze me w/ your handiness. dp
-
All kinds of things go through your head when the band saw is down, :) very good job ,should take a lot of wood off fast. :)

Thanks Derik. I'm going to try and get my redneck engineering degree from walmart university this summer ;D
Pappy, the bandsaw isn't down anymore, its gone. I'm watching for Grizzly to have a sale on that black anniversary model.

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.

Tight wad...........

Very Frugal and inventive. When Paleo man needed a tool He made it. Good work Clint..
-
Clint you are the redneck Edison ;)
-
Call it the "Clinto!" :laugh:
-
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.

I like that Greg.... "Clinto" :laugh: :laugh: :laugh:
-
If I was not so stinking Lazy I would make myself a Clinto !!
Good job Clint

Maybe Clint should market the Clinto. . .?
-
did you reverse every other blade so it cut on both strokes?
-
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.
