Playing with walnut and my Shaper Origin. Bad weather is starting to set in so I'm spending more time in the shop. I just finished some new LED light fixtures.

This is 43" long.



Detail of fixture.



Bracket detail.



Next project is a makeup mirror/station cabinet for DW out of walnut.

That is a beautiful fixture you created, get ready for some orders ,


Can we see a night shot of that. The brightness must be like daylight?




Thanks,


John

I love my Shaper Origin

I love this tool. I occasionally need a printed circuit board for some project or other. In the past I have etched them with acid. Messy and time consuming. I would draw the picture, print it with a printer, heat transfer that onto the board then dunk it in the acid solution which would eat the copper layer off. Then I would have to very carefully drill all of the holes.



With the SO I still have to draw it up. There was a bit of trial and error before I figured out cut settings. The last one, the top one in the above picture, took about ten minutes. This method puts the holes exactly in the right places. Accuracy is exceptional for a hand held tool. That board is less than an inch tall.

This is a few of the mistakes, as you can see I can even cut the piece out.

That Shaper tool is incredible. Gotta love milled circuit boards -- we don't see many of those anymore! I've done a few boards over the years using the positive or negative photoresist followed by the ferric chloride etch.. but now I usually order my boards through oshpark.com. I could barely manage to get 0.05" SOIC footprints to work out with the photoresist technique; with today's VQFN and smaller/denser packages I expect the DIY photoresist would really be a struggle.

How fine can you go when making PCBs with that Shaper -- any idea what traces & spaces widths or pad pitch it can reliably manage? And.. dare I ask.. have you tried to make a two-sided board? It seems like it might work.

You can get pretty accurate. The traces on this board are 3mm, a couple are 2mm. My bits are some of the limiting factors. The first one I did I just outlined the traces with a 20 degree engraving bit at a depth of .003" (forgive me I think in inches) I didn't take out any of the unneeded parts between the traces.I don't have any way to measure the spacing but it would appear to be .002" or so. I checked with an ohm meter and everything was good.

The smallest end mill I have is .0625. For the one in the picture I did as much as I could with that bit then ground the sharp point off of a 20 degree engraving bit and finished up in the tight places with it.

Two sided should be possible especially, since you would have the holes to help with alignment.

My stuff is pretty simple and are almost always one offs. I could probably just solder on a breadboard but, I hate doing that and think they just look messy. I wish I had this when I built an electronic ignition for my Cushman.

I did the old photo tech boards but only for through hole based boards. Even then if I needed really thin traces I had issues occasionally ... started ordering my boards out and they came back drilled and with plated through holes. I’ve soldered SOC with fine tip but never used any QFN packages that weren’t already soldered to a DIP adapter

Mirror cabinet

I just finished a solid walnut mirror/makeup cabinet for mumsywumsy. It is really hard to get any pictures so I did a video. Pardon the shake, didn't realize just how shaky this old guy is getting.

I'm sure someone has told me how to embed videos but I don't remember.

Nice work on the cabinet, I like the auto shut off light.

Copied this pic when I first saw it last year, so i could find it when I was ready to start my shower.....LOVE the look of this.

The shower walls look too thick for paneling.....is that a beadboard, or separate planks with a plywood backer and sealer, or what? And if they are separate planks, did you bevel or round-over the edges? And how did you seal between the planks? I thought about just using copious amounts of spar urethane, but that would require finishing in a horizontal position....due to space limitations, I'm planning on building in-place. And my walls will only be waist-high.

Thanks for any insight.
