Voxel: Flush Trim and Edge Sealing

I’ve flush-trimmed the plywood edges and filled some gaps/sealed the edge.

Using a flush-trim bit on my router I’ve flush-trimmed the edges of the front and back pieces on the Voxel cabinet. This turned out to be surprisingly easy. Unfortunately I didn’t take any good before and  after pictures.

I think I learnt something from my experience with the router when cutting the driver hole earlier. — Since the flush trim bit is larger (1/2″ diameter) I lowered the router’s RPM. Also, I made sure that the flush trim bit was clean by frequently wiping off the bit and well lubricated all the time by spraying a little bit of WD40 on it at times. Also, given the fact that the router spins the bit clockwise when looking at it from the top, you want to go around the cabinet counter-clockwise, since we now care about an “inner”edge (as opposed to when cutting a hole, where you care about an “outer” edge and hence go clockwise).

After the flush-trimming the plywood edges still seemed a tiny bit rough, so I used some 220 grit sandpaper so smooth them over. There were also some gaps in the plywood that I needed to fill. I did this during the edge-sealing step, where I just wiped some glue onto the plywood edges. I had some wood filler but it was kind of dried up, but getting glue into the gaps and then rubbing the wood filler in with my finger seems to have worked.

Here is a close-up of a filled gap (the greyish-white part of the plywood edge):

I am not sure if I sanded through all the edge sealed glue or not, but the edges feel completely smooth now and you can’t feel any ridges from different layers of plywood anymore.

The Voxel cabinet now looks like this:

I think I’ll call that good enough…

Next step is to prime with spray-paint and then spray-paint the cabinet.
