Saw mark texture
Has anyone ever tried to recreate large circular saw marks as seen on old floor boards?

Re: Saw mark texture
Tilt your spindle a few degrees, and cut some large arcs.

Re: Saw mark texture
Ger21 has the same idea I do. If you don't then the saw texture becomes a 3D job that will take considerable time to cut.

If you want the burn marks too, use a dull cutter.

I've not tried that on a CNC, no.mrwoodworks wrote:Has anyone ever tried to recreate large circular saw marks as seen on old floor boards?
Was just thinking maybe a hand-held disc sander could simulate the look a lot faster anyway.

Re: Saw mark texture
I know I've made those marks plenty of times...too many to count,,,but would it be possible to post a picture of what you're looking to achieve....??
Thanks,
Michael

Re: Saw mark texture
I have a Lucas 10-30 swing blade mill and it does a decent job of doing just that. Probably not as pronounced as one of the larger circular blades does. The blades on my mill are 24" and have 5 teeth. Lots of fun and it makes lots of lumber for me.

Re: Saw mark texture
You could clamp your material at a very small angle to the table (maybe 1 or 2 degrees?) and then cut arc shaped fluting tool paths with a larger end mill. The depth of the flute should be the incline height of the material over the radius of the arc. Then multiply that path along the material and adjust the starting depth for each fluting path (find your old trigonometry text book).
Sounds like a lot of work, but with the rounded flute slope option that might look similar. After all, maybe easier to do with a table saw...

Re: Saw mark texture
I was thinking the same thing. Just shim the work a bit at one end, then use a large fly cutter to run some irregularly spaced half circles that just barely dig into the wood. Sounds like one of them things you need to try on some scrap wood first.Tailmaker wrote:You could clamp your material at a very small angle to the table (maybe 1 or 2 degrees?) and then cut arc shaped fluting tool paths with a larger end mill.

Re: Saw mark texture
The saw marks he is probably locking for would be from a 52 inch diameter blade. Thar would be a rather large fly cutter.

Re: Saw mark texture
Highpockets, that's a close representation of what I want to achieve. Saw mark arcs should be closer together though. Yes the marks should represent the kerfuffle of 48 inch or larger circumstances blade on wide planks. I only have a three axis so tilting the head is not an option and I don't have an aggregate head to put in the tool holder either.
Appears doable with modeling but way too time consuming.
Handheld disc sander is not consistent enough.
The incline stock idea has some merit.
I'll keep plugging at it. Thanks for all the responses.

Re: Saw mark texture
Tracy,
Attached is how I achieved the look. It's a starting point that you can work from to get what you want.

Re: Saw mark texture
No, you run the fly cutter along a 52" diameter arch. You could do it with a smaller bit (like a 1/4" or so), but it would require several passes to make the cut wide enough. Highpocket's approach looks good though, not really the marks you'd get from a slightly angled saw blade, but close enough to give you the "sawed" appearance.larrybadgett wrote:The saw marks he is probably locking for would be from a 52 inch diameter blade.

Re: Saw mark texture
Something like this. I did this on the fly by tilting the work piece and creating separate toolpaths/cut depths for each vector, but you should be able to use the "project onto 3D model" option if you make the model larger than the actual work piece.
