I was surprised to find that, as I started, I couldn’t even view the website because the hosting company had updated some software without updating all the requisites so the site didn’t even work!  Sigh…

In any case, if you’ve been one of the ones who have been checking in, I apologize for letting this languish and will try to do better in the future!!!

The map covers most of Penobscot Bay, from Owl’s Head to the mouth of the Penobscot river at Sandy Point, with Camden on the West side, Castine on the East.  You can easily make out Belfast, Camden, and Rockport Harbors, Lincolnville Beach,  Vinalhaven & North Haven, Islesboro, and Castine as well as the coastline around Searport.

How could I refuse?

These were engraved and cut into 3mm Baltic Birch plywood with my CO2 laser and then sanded and finished with a clear coat of water based varnish.  I made 18 of these so that all the kids would get one.  Great fun!

I figured a nice Brass Knob would look good.   Something with a nice smooth curve and a polished look.  As I thought about it, however, I realized using the Lathe cross slide controls would make it very hard to get a smooth continuous curve.  Reading up on this kind of turning I learned that smooth curves like this, if not cut on a CNC lathe, are generally turned freehand.  I’ve done enough wood turning so I thought I’d give it a try…

Heck, that wasn’t so hard…  Let’s continue…

Here is the setup of the support I used to freehand turn the brass knob. The carbide turning gouge rest on the 123 block held in place with the magnet.

Finally, with the knob left with just a little nub at the bottom of the base, I needed to make a clamp that would hold the knob while I machined the base.  I couldn’t use the vice directly on the soft brass, so…

First time I used the Boring head with the new MT2 post I got as a Christmas present. I needed the adjustable boring head to machine a two level hole exactly the same diameters as the brass knob.

Cross-section view of the clamp. Note the two tiers of diameters so the knob is held tightly at top and bottom without marring the polished surface.

Here is the knob, clamped on the Mill so that the nub can be milled off and a threaded hole can be machined exactly into the center of the base.

And here is the result!

The box was made of 3mm acrylic, cut on my CO2 laser and ‘melded’ together with acrylic solvent.

Part of that is due to the waste board that I have installed on the bed.  That consumes about 19mm of height.  But even accounting for that, most of the Z travel capability is unusable because the Z Post hangs so low.

After exploring various options for getting more Z range, I decided that lifting the whole top transport assembly 50mm would give me a enough range without introducing much risk or losing a noticeable amount of rigidity.

So, using my NEW Mini Mill, I was able to fabricate the pieces to add a rigid lift.  Here’s the new look:

The good/bad part of this style is that most of the woodwork is curved, with very few straight lines.  I concluded that, to keep the proper flow and sweeps AND still have all the interlocking joinery line up, the framework, at least, needed to be cut on a CNC Router.  Cool, I’ve got one of those

To make a VERY LONG story shorter, I did some trial cuts of some of the longest parts in January of 2019.  From these experiments, I realized that the CNC router needed to be larger to reliably make the parts.  Consequently the project languished until I finally upgraded my CNC Router to a larger, more solid, one this year.  This spring I made the base, then made the top, and left the pieces to cure over the Summer while we were in Maine.  When we returned, and got some time, once Kate & Paul’s Wedding reception was completed, I did the final finishing, assembly, and installed it in our Living Room.  I’m quite pleased with the result:

Reading up on various machinist’s fora, there were two recommendations for early add-ons to any mill purchase.  The first is to add a Digital Readout, which is needed to get around the normal backlash in the table positioning controls.  I knew this right away and added that upgrade as part of the initial installation.  The second recommendation is to add a power feed on the X axis (the long axis).  So this addition was expected and I ordered the parts and raw material right away.

It was necessary to use the Mill and the Lathe to make the custom parts so was, on the whole, a great first project for the ‘Machine Shop’.

Here is the design that I first captured in Sketchup, a 3D CAD program I’ve used for years.

Here are the pieces before assembly:

Power Feed Parts ready for assembly. All but the gear motor, bearing, and coupling were machined in the ‘machine shop’.

Finally, here is the final power feed.  It works well, although I have to admit that I had to upgrade the motor to a slightly more powerful gear motor.

It took some creative rearrangement of other items in the workshop, but, having had a few years in the shop, I was able to determine what’s needed all the time and what can be tucked away and pulled out only when needed.  Consequently, here is my new ‘corner machine shop’!

I’ll now be able to work on metal!  Not just cutting on the plasma cutter or bandsaw, but actually milling, drilling, and turning accurately!
