Re: Why would we want to make dovetails

I consider any creative original work to be mind crafted. Be it my hand on hand tools or on wood feeding it through a power tool or on my keyboard/mouse drawing up vectors, all the hard initial work comes from my mind. The second step is always output done using my hands. What they do is what my min...

Re: Love the drafting tools/features.

Thanks Jam2. Appreciated. The Area option of the measure tool has also been invaluable. I had a student designing a chair and she wanted the back to pivot. Essentially an extruded CNC cut shape of solid maple that felt good when leaning back on it. She want it to come to rest with just a slight lean...

Love the drafting tools/features.

I have to throw a long deserved compliment to the programmers of VCarve/Aspire/Etc.. Brilliant. I have found the drafting tools invaluable. The measuring and dimensioning tools specifically. My latest furniture project is a TV Tray Table. Not much CNC work needed to make it, but the measuring tool h...

Re: Why would we want to make dovetails

Why? Uniformed demand. You can make all sorts of fancy joint using a CNC. Much more if you can clamp boards vertically or at any angle under the spindle plane which I can. I retired 2 years ago from teaching furniture design and fabrication to college students. I had a box full of fancy CNC cut join...

Re: Tapered table leg in VCarvePro

"without a rotary axis". No modelling tools. Hmmm. Fluting tool and a tedious number of tapering lines carefully plotted to duplicate what a 3D toolpath would do travelling from the wide end to the narrow end. Each side a mirror image of the other, and as a 2 -sided job the same toolpaths used on th...

Re: Need pointers for how to draw arch with Mortises

Under the modelling tab, there is an icon for creating a shape by extruding by one or more centerline vectors. So I used your arc shape, clipped the bottom off, and used the sides and top arc. I drew a vertical centering to use as the drive rail. Then picked the arc vector. Although there are other ...

Re: Couple videos of furniture parts cut with Aspire

Always enjoy your videos RS. Curious if you've ever had any breaking at the top of the legs where the grain is short after cutting the joint? I know some woods like to split, and might be more prone to breaking than walnut.

Re: Need pointers for how to draw arch with Mortises

DXF file works. Only data I still need is the thickness of the posts/tenons. 1/3 of 13/16 would be .2708, an odd number. 3/8" would be my guess, but say you resaw from 3/4" thick wood ending up with smooth thickness would likely be closer to .2708 than .375. Here is a version with the mortises 3/8" ...

Ok! Here is a 2d drawing of the arch with the slot locations. I'm using 13/16 material for arch piece.

Sorry. I'm still using Aspire version 10.515. If you can export your drawing as a DXF file and post it here I'll be able to open it. You'll be able to open my 10.515 version reply.

Re: Need pointers for how to draw arch with Mortises

This was my first thought, but I think the bottom of the mortise profile cut will also follow the shape of the model, so you won’t have nice flat bottom mortises. True, but it wouldn't be hard to trim the post bottoms/tenons to the high end of the mortises. And if you do a follow up profile with a ...

Re: Need pointers for how to draw arch with Mortises

You could use the CNC with the arc laying flat, and planed or re-sawn to 2/3 the final thickness. Then lay out rectangles along the arc to pocket the depth equal to the thickness of the tenons. Then glue a board over the top for the last 1/3. Dogbone corners will account for square bottoms of the te...

Re: Need pointers for how to draw arch with Mortises

You can profile the inside of the mortise outlines and map them to a 3D surface. They will still have radiused corners to deal with, and stepped/arced bottoms. And if you model the shape using an arc the shape of the top of the part you'll know the height of the arc. Make your material size the same...

Re: Need pointers for how to draw arch with Mortises

If you can clamp the curved part vertically, then draw a top view of it, lay out where the mortises would be, them map them to a 3D surface. Of course you'll need to make a 3D model of the curved arc top edge to do that. Then of course you'll need to consider making the tenons to fit. Can't help you...

Re: Very slow rotary turning near the outside diameter

Your machine may have a software configuration that has a feed speed max limit, which would prevent going any faster even if you've set a faster value. My LinuxCNC software on my Probotix CNC has a config file (can't remember the name right now) that has axis feed limits to prevent the machine from ...
