Hi Neil, also over here a fillet radius up to around 0.04 looks like it works ok but not much larger than that with those tight bends in the outline.

If you remove the tight bends as shown above you can then go larger.

If you know you want to put a fillet on some area you kind of need to keep tight bends out of there until later on.

Thanks Michael - Excellent - thank you for the educational/detailed reply - that solves the problem. Will do!

Thanks again to Michael for the help. This this is pretty good - would've liked the fillet to be .625 but .25 will have to do. - can always use a 3/8" roundover bit on it. :)

Hi Neil,
try these reworked curves to get the larger fillet.

Thanks Barry - what exactly did you do? The shape looked about the same. Was able to get this one to .4 roundover which is pretty close.

Hi Neil,
I reworked the areas shown in the photo.
I moved your arm cut over slightly as the thickness from front to back was to thin for a 0.25 fillet top and 0.625 fillet back.
Also the neck cut out curve had a sharp corner where it should have blended and gave a strange result when Boolean difference was applied.
This was the order I filleted.
1) Fillet back 0.625 but not the top edge.
2) Fillet top 0.25 again not top edge.
3) Boolean difference neck cut out.
4) Fillet top edge 0.2
Attached is the result.
Hope this helps
Barry

Thanks Barry!

Where am I going wrong on this - can't fillet any more than .125" - what is the trick? I'd like to do between .25" and .375"

Thanks for the help!

Hi Neil, what edges are you trying to fillet ?

- Michael

Hi Neil,
your model will fillet at .25/.30 if you do the fillets before you Boolean the neck pocket.
The neck pocket as it is causes a slight sliver so by slightly moving or adjusting width will improve it.

Why can't I do that? Hmm. Well you always save the day Barry - thanks! Can you help with this body as well? I'm having the same problem with it. I can' get the fillet anymore than .1" before or after the pockets and contours.

Hi Neil,
Just tried your last post and it fillets 0.2 on the top any bigger and it runs into a pocket.
Did exactly the same as my previous post separated the solid, untrimmed the top and side to remove neck pocket.
Re trimmed side with belly cut out and joined to form a solid, applied fillets top and bottom and to finish Boolean the neck pocket.
Hope this helps.
Barry
Ps: your body profile right side neck curve isn't smooth?

---

Thanks Barry! - hmm that must be a previous version thought I smoothed that curve out - thanks for pointing it out and for the help - much appreciated! Will be making that arch top very soon - thank you again for your help with that.

Here is the last body Barry helped me with after milling . . . vert happy with the contours. Hard to see the arm contour in this shot but it's perfect. I too am looking forward to version 4 with dimensioning.
