Would like to create an inlay grid in MDF for my mini mosaic tiles (How to?)
Hello, I have a mini mosaic I've been working on using 3/8 (10mm) square tiles. The 'picture' (my interpretation of the Fibonacci spiral) comprises 5,487 tiles (59x93) which is ~ 24" x 36". The tiles are ~ 1/8" deep.
I thought it would be great if I could use the CNC to machine in the little pockets in 1/2" thick MDF, in effect making a custom 'backer board' I would 'seal' the MDF with a diluted Weldbond wash, and then glue in the tiles with Weldbond as time permits. This is for indoors only.
Is there an efficient way to design a grid like this in Aspire, rather than drawing in all the individual lines or squares? I'm thinking a 1st round of roughing in the squares (1/8" bit) and then using a V-carve bit to finish the square outlines, since the tiles have a nice (45 degrees?) slanted angle. Or could I just use the V-carve bit for the whole operation since the squares are so small? The pockets would likely be just 1/32" deep, enough to hold the tiles in place.
I may have to do two boards, like two of 13" x 37", depending on the spacing between tiles (I may or may not grout afterwards).
Thank you for any comments on how to design the file.
