Creating a Resin Filled Table With the Longmill

Patrik from Sienci Labs connected us with Alex from Curate Vintage to trade a custom made table for some custom Sienci Labs swag. In this project, we are carving the logo into a table using the LongMill and filling in the pocket with epoxy resin. 

Software

For this particular project, we are using Easel by Inventables (http://easel.inventables.com/users/sign_in). Easel is a free, web-based, and simple to use CAM software that is excellent for beginners looking to do 2D projects like signs, trays, and lettering. Easel is compatible with many CNC machines, including X-Carves and Shapeokos. 

There are many video tutorials on using Easel available online.

Importing an Image into Easel

By using Import — Image Trace on Easel, you can import JPG images to cut with your LongMill. Images that are black and white or made up of solid colors typically work best for this process. You can also watch this video (https://www.youtube.com/watch?v=Q-sfK-QxwzQ) which covers a slightly different method of using an image to create a carving.

Feeds and Speeds

The feeds and speeds used for this project was 60in/min (1524mm/min), 15in/min (381mm/min) plunge rate with a 0.125in (3.175mm) depth of cut. In the video the depth of cut says 0.18in, however since the pocket is shallower than the max depth of cut, it only cuts 0.125in down. These speeds are fairly conservative and should work with most types of woods.

End Mill

For this project, we used a ¼” downcut end mill (https://sienci.com/product/1-4-spiral-down-cut-end-mill/). We chose a downcut end mill because we knew that we would not be able to sand or finish the surface of the table after it had been cut or poured, as the surface would be ruined, and using a downcut end mill would prevent any splintering or fuzziness on the top surface.

Epoxy Resin

We bought 946mL of resin for this project and ended up using approximately 2/3s of it. This was our first time using epoxy, but we found it was a fairly easy process. Our particular resin required a 1 to 1 mix ratio which was measured out by scale. We added powdered color mica resin dye to provide the color. Our particular resin brand was called “ArtResin” which hardened in about 24 hours, but you can find an epoxy that fits your needs.

Project Learnings

This was a super fun project, and things turned out pretty well. 

If we were to do this project again, we would probably want to use solid wood or high-quality plywood for the table material. This is because melamine covered MDF does not allow for us to sand or mill off the surface of the table. Instead, we needed to be careful to drip resin onto the uncut parts of the table.
