Welcome Home...THANK YOU FOR BEING A PART OF OUR COMMUNITY

There was recently a discussion started on how to obtain rough saw cut marks on scale material.

This is how I did it.

There are certainly other methods. The approach I am presenting is simply one I was tooled up to implement & one easily reproduced. It could be accomplished on a drill press.

It's most commonly seen on bone scales ......

However.. the original query concerned hardwood. Toward that end .. I used scraps of a wood laminate and Desert Ironwood. Above is the initial result in the laminated wood material. The carbide cutter is offset ~ 2 inches from the center of rotation. The cuts are spaced @ ~ 3/16 of an inch. The depth of each cut is ~ 1/16 of an inch.

The initial 4 cuts in the Desert Ironwood used a radial offset of 2 inches for the carbide cutter .. the depth again was ~ 1/16 of an inch ..however.. the distance between the cuts was reduced to ~ 1/8 inch.

I reduced the offset radius of the cutter from 2 inches to 1 inch for the inner 5 cuts. The depth of each cut & the distance between the cuts remained the same.

Note: One of the carbide cutters was removed for this operation.

I found the result acceptably close to that found on the scales of the Rough Rider. I believe .. once contoured for scales .. it would be a good match.

I cleaned the results up by briefly sanding with 400 grit wet/dry sandpaper.

........................

A similar Carbide Tip Adjustable Circle Cutter is available from Harbor Freight for about $6.oo. I used a Grizzly G8689 Mini-Mill ..however.. the same could be accomplished with a simpler drill press.

.

Obviously .. the results could be modified by changing the settings from those I implemented .. i.e. offset radius of the cutter .. distance between cuts .. depth of cuts.

.

This is one method of obtaining that saw cut look that was originally queried.

Good idea there Dale, I wondered when I saw the incoming email before I hit the real page here how you would do it with a drill press, but your photos make that clear.

Since I moved from Ohio to Virginia we bought a townhouse, kids are grown and gone, I have no garage any more and anyway I have not had much in the way of tools since I came from Africa 17 years ago. So I'm very limited but a drill press, bench grinder and sander might be in my future. :-) Small models that I can store in a small shed and bring out to use in the little back garden on a portable bench every now and then but I can see I will need a few more tools.

Dale,

I am very impressed with this.  Considering we discussed this briefly, I only found the one example online and it was not quite what he was looking for.  I think this is going to fit the bill much better

Thanks, Jan.

After giving some thought to the problem @ hand .. I wanted to come up w/ a method I felt was safer & easier to implement. A method requiring tools which more of us would have access to.

.

Safety.

Well .. common sense is still required ..but.. a bent & therefor unbalanced saw blade spinning @ a high rate of speed .. I find scary.

.
Further .. so much was dependent on the "feed rate" of the "saw method".

.
Required tooling .. a $6 part from Harbor freight & a simple drill press.

.

Note: When making the cuts described above .. do them slowly. i.e. a few thousands of an inch @ a time .. until the desired cut depth is achieved.

.

This method .. offers more control & a more reliable outcome .. imo.

.

Thanks again.

.

Enjoy
