Blade for 3D cutting


rjweb

Recommended Posts

I just cut some mahogany in 3/4 x 1 1/2 and I used Pegas #5 mgt. I love these blades. They seem to be good for most anything so far. But, I'm a newbie so take it for what it's worth. I had to cut 8 of the same thing in compound 3-D cuts. Here is what I was cutting.

I use Polar on thicker but some 3D is thinner like bird houses or the birds to go on them I use a # 5 reverse. The other thing I found that helps is a jig to hold the project in place while you cut . I do not have capability to show Pics but sure someone else will know what I am talking about and can show you or you may have made one yourself.

While everyone will have an opinion on this reverse tooth blades are not designed for compound cutting.  To cut best you want a blade that removes as much sawdust as possible.  That is a skip tooth design like the FD  Polar.  The reverse tooth design pushes sawdust back in the cut on the up cut.

Ok, first - let's clarify on what you mean by "3-D" ornaments - are you talking about compound cut ornaments?  I think so, but just want to make sure.  If so, there were a couple of threads over the past year or so discussing and giving lots of good tips and information on cutting Compound ornaments.  If so, one of the big tips provided that I "missed" until I tried to cut my first ones is to "NOT use reverse tooth blades" but to use skip tooth blades. The polar blades are skip tooth blades.

Here is the thread with most of the good help and tips from several members here, in particular CharleyL, Bill Wilson, and dgman.  Charley gave detailed information with photos as I recall. http://www.scrollsawvillage.com/forums/topic/24171-compound-cutting-wood/ It is well worth a read through for anyone who is just learning to cut compound cuts for sure.

Then in this thread, I showed my first compound cuts and asked why use skip tooth and not the reverse blades, and Bill Wilson gives a great explanation (which is why I am sharing link to that thread - not to show my work again 😉☺️😞

If you haven't found it yet, Steve Good has a 3-d or Compound Cut Birdhouse pattern - it is the first one I tried and show in that thread above.  I tried it because I thought it looked simple enough for me to try. 😄 http://scrollsawworkshop.blogspot.com/2017/12/compound-cut-bird-house-and-stand.html This same post on Steve's blog also has a link to his DIY clamp to help holding it while cutting out compound cuts as referenced by @bandaideman above
