A simple1 X 30 belt sander will go a long ways in helping with the rough profiling of scales.

NOTE: I state "rough" because it is easy to remove more than the desired amount if one lacks experience. I would suggest final forming with a small file ..or.. needle files. They are "reasonably" priced ..&.. tis likely what MANY of us started with as our first belt sander. Also, never toss out old worn belts ..as.. they can be implemented as a higher than originally rated grit belt.

I've been very busy with many projects and finally have got most of them done.. :). As to the 317 it is progressing  just a bit. I have managed to get the blades back to a point with a lot of work and I also discovered that the main blade has had the tip broken before and its been redone and then the tip was broken again by the time I got it.

 So its close to a quarter inch shorter that the stock blade. I have been looking for tools to shape the scales after they are cut and came a cross a dremel kit with a most every thing I will need. 

  I have the balsa wood and the black walnut for the scales is on its way. One of the few problems will be removing the scale on the other side and I've decided the trim the pin that holds it on. However I will be sure its stable.

The absence of any tools is a detriment to accomplishing this yourself. It does throw a definite impediment into the process.


However, you do imply you've the skills & confidence to fabricate a pattern out of balsa wood .. that is a very positive attribute.


A set of wood scale material may not be as pricey as you anticipate ..as.. they can be obtained in the range of $5 ~ $10 .. less if you have some appropriately sized "scraps" available for use.


NOTE: The highlighted & underlined "price range" is a link to a source for said scale blanks. If you click on the link .. it should take you to the site. Other options are certainly out there.


I agree that wood is easier to work with. Simple hand tools .. coping saw, rasp, file, sandpaper, etc .. are all that is required. While the same is true for bone .. jigged bone is typically a bit more expensive. I personally find the natural wood grain more aesthetically pleasing. My wife absolutely refuses to entertain anything but.


... I believe ...

The biggest hurdle for you is the removal & replacement of the center backspring pin. I could think of ways around that ..if.. you were interested. However .. most of us would remove the existing center backspring pin & re-introduce a new one in the process. Correct me if I am wrong ..AND.. no offense intended ..BUT.. I suspect that to be pushing your comfort zone. Again .. I could suggest (legitimate) methods to replace the scales without removing the center backspring pin. However .. most of us would replace the center backspring pin in the process.


Adhesives .. there exist a # of 2-part epoxies that will sufficiently secure any replacement scales in place.There are choices you can make & things you can do to further enhance the success of using adhesives ... roughing up the mating surfaces .. correct choice of adhesive .. etc.


Wally .. would you post a pic of the blades. You've intimated the tips are broken. How badly are they damaged ?  Would you wish them restored, i.e. reground to a point ??


Thanks again for joining our "Repair & Mod" group.

I've not got any tools I could work wood or bone with but I do have an idea. I used to build model planes using Balsa wood when I was around 11 yrs old.

  I got to thinking about using Balsa wood to make the pattern and use it get where it fit the frame of the 317 and the wood is soft enough that I should be able to use it to make sure it fits the frame and mounting holes in the frame.

  Then I could select the type wood I wanted use and have a ready made pattern to follow while making the scale or if I need to have some one else make the pattern.

  Black Walnut come to mind as a wood to use for the scales. however that wood is harder than a rock and pretty expenseve or at least it was 25 or 30 yrs ago. There are several other types I given some thought to.

   Bone scales would be very nice, however I'm not a fan of the bone scales as they do not feel right in my hand. I have an Uncle Henry folding hunter with the bone scales and they make it feel like its way bigger than it is and it feels uncomfortable in my hand.

  So I'm thinking of using wood scales as replacements. Wood would be easier for me to work with and with the balsa wood pattern the scales could be cut and all I would need to do is finish them out. 

  But here's the kicker. I have no way to mount the scales or do I know how to mount them or brad the one pin that us used to help hold the scales on the frame and if any kind of a glue is used to help hold the scales on. 

  So it would probably be better for me to have it done.

Thanks for transferring the pertinent pics, Jan.

I'm w/ Derek on this one .. it would be a great time to replace both scales. And the old scale on the other side could be used as a "pattern" when making the new scales. The choice of material for new scales is almost endless & the result would be very unique.


Wally .. what exactly are your questions Re: the scale replacement. Also, what tools do you have at your disposal ?
