Mitch, Number one, check out the knife, what is its age, etc.
This is a Camillus, Buck contracted its construction back in the past days. It is also the largest number produced version of the Camillus era knives, made from mid 70s to mid 80s made in great numbers. It does not have Bos heat treated blades. It does not even have 420HC blades, it is likely 440A. It had Delrin plastic scales that were hot pressed onto the liners with the holes you see acting as internal rivets.
That all said, you can email Joe Houser at Buck and ask him what is available to be certain. Go to website for info. BUT, if you have the desire to DIY you can do it with minimal 'tools'. Fancy tools only make it easier, with some sweat you can do it. Thats what I have been saying on the photography thread........The same thing applies.
Once you decide you can do it start a thread asking for advice and if you aren't piled high with help I will be surprised. Go check out the wood, and I said wood, at the links below and see if you aren't inspired. Start out with maple, or walnut or some figured USA wood, not offshore wood, yes it is pretty and hard, but it is hard to work and some of it even has dust that will make you sick. You can do it with good epoxy glue, some rubber bands and sandpaper. Do fancy wood scales first , then tackle other stuff. The wood slabs you buy will let you make several folder scales for under 10.00. You can get someone to saw you some small pieces and then you can use something as simple as a hack saw blade wrapped with a tape handle to cut the angles.
Go look at these for slabs.

In all honesty, if you pay 50 to 100 dollars to get scales on that knife, it will be like you will be putting NASCAR racing tires on a subcompact car.
That my opinion.
