Tried roundover cutter

[khalid]

First time in my life i tried roundover cutter at edges and it worked gr8...

[dlcw]

Sweet. Nice job Khalid!

I am about to try my hand at a roundover bit on a product line I'm working on. Hope to save me bunches of standing at the router table time.

[elcar903]

nice job :)

[khalid]

Thank you all... and i will suggest must try your self ;)

Oh yeah i like the round over too, about half of what i do gets a round over edge. My particular bit is a magnate and it works well

[JimFabLabFulton]

any advice from your experience?

[markevans]

That is nice, did you have a CNC bit for this or did you have to modify a conventional roundover bit? Asking as I have not been able to find them in 1/4" shank

Try Magnate or Whiteside.

Thanx, I did not know about these. Not as good as what Rockler has in 1/2 in. shank but a lot better than having to modify a bit with a bearing.

The Rockler bits have a end mill built in so you can cut out and round over in one operation.

As much as I've explored, there is still a lot out there that I have not seen. thanx for the leads.

These have a lot more uses than just rounding over the outside edge of a profile cut and you can work with any thickness of material unlike plunge cutting roundovers which aren't as versatile.
Not very impressed with Rockler bits as a whole compared to other bits recommended here for CNC work, although I do use their keyhole occasionally.

[khalid]

Keep in mind if you want the good roundover then your depth of cut= radius of roundover..
and i used the roundover for plunge machning 2mm doc/pass..

[khalid]

if i was you i would purchase 5pcs/70dollar with free shipping..

Recent experience. The last 2 or 3 plaques I used a brand new Magnate round over. My rpm is 10k, my feed is 3.3 inch per second, my plunge 1 inch per second, my direction is climb and .08 pass depth and i add ramps. I get a smooth cut going with the grain but against the grain i get a real rough chip out effect. With my profile cut out i use a quarter inch end mill and every thing works fine. Any ideas.

[scottp55]

Rick, Is that the 1/2"Radius plunge roundover you linked above?
I only use Pointed Roundovers, but speed seems low,and feed a little high for Walnut.
Have you tried editing the passes so the last 2-3 passes are very light(.02-.03") and a final pass at .01"?
I usually get a slight rough spot, but it's at 45 degrees to the grain, and it moves 90 degrees depending on climb or conventional, but similar in slight roughness.
Just a thought, but mine need just a touch of 320 and 600G to look like this(only pic I could find, but walnut keyfob batches cut the same with a Whiteside .25"R)
Totally different bit though.
Did it just start happening?

[cowboy1296]

i will try making that adjustment and see what happens.

[scottp55]

OH, Were you spiral ramping?
It's the only way I do my cutouts.
Almost exclusively a conventional cut here.
Hope it works with that cutter!

I cut some poplar today, slowed down the speed rate a tad and turned the rpm up one notch. Smooth as a baby's butt, but we will see what it does on black walnut next time

[scottp55]

I leave Poplar cutting to the Beavers:)

[cowboy1296]

It was a mistake to buy it for what i do. After it is gone i will never guy it again.

[scottp55]

Maybe the new "Moulding Toolpath" that just came out would be good for you?

Yep, it's a major tool in my shop. Most letters are shaped with a bradpoint bit.

I wrote a post on the topic, "The humble little bradpoint" My favorites come from Woodline Tools.

[chiloquinruss]

Love using the brad point bits for lettering. Sure makes a neat looking sign. Letters and border all initially scribed with with brad point then cut out. Russ

Hey train guy i sent you a private message about flat masters, did you receive it.

And i will try that bit.

[chiloquinruss]

No, but I just did reply, sorry. I never seem to notice that 'notification' thingy! ;) Russ

[cowboy1296]

yeah i got it, you may have saved me a bunch of money, thanks
