Hey guys - this is by no means the quality/difficulty as Ric haha, but I enjoy when people post things here so I figured I would put it up. I made a little name sign for a friend's baby. Hoping to get it final paint and mounted before work this afternoon. Another success with Fusion360 rs-274 post. Attachments:

Even more surprising...going to have to give MDF a try...been seeing some nice projects cut with it lately... Think I know what you're saying with "nice shallow cuts with full tool engagement" but would you mind elaborating on that? Thanks...Ric |

Thanks...Ric MDF cuts nice actually... hard to paint because it sucks up paint like crazy but it looks nice. On a cut tool path in fusion normally the tool is only cutting about less than half the width of the actual tool. Since its plunging into the material on a contour pass, it's cutting 100% of the tool width. So since you have a full tool engagement, I typically do shallower step downs at a time with the 1/8" bit so it doesn't snap. |

(I ask because my pile of broken 1/16" EM's is growing... ;-) might want to try "sanding sealer" as a primer on the MDF... |

Knock on wood, I've never broken a bit other then bits like the SC50 engraver bits. With the 1/16" end mills, which I use a lot, I'm using a depth of cut of .06". However, I'm just using redwood, which is a softer material.

I usually go about .08 d.o.c. with the 1/8, could probably go deeper but it works for me for now. |

For MDF I'll prime the top and bottom and sand smooth to get off any raise nibs before machining to give sharper edges on the top and bottom faces, it's sort of like putting tape over the cut line for reinforcement.

I like that idea, but I have more issues with the cut vertical sides... they seem to suck up paint like a sponge! haha

Does that help the "little hairs" on the sides when cut? Because I prefer to use MDF for stuff like this.

Don't know. I only spray after I cut. It might, since it will make the top surface stiffer.

I find it does, anything will work to make things stiffer, paint, shellac, polyurethane (I usually dilute it 30-50% so it soaks in and reinforces more than just the surface). Shellac and lacquer will be the fastest drying. |
