Listen, You have to see this.
Here is a video of the Taig ER spindle running on the HB2. If it will not run in IE7 or IE8 browsers, turn off the protected mode. Microsoft has gone psyco on protection!
In the close up pictures the camera microphone was about 6 inches away from the motor. Note that the Stepper “tunes” are not drounded out by spindle noise. The farther away shots give a clearer understanding how quiet the Taig spindle operates. The cutting in this video was at 10,600 rpm and the travel was 50 IPM.
I love this operation and have a complete new spindle setup on order. Actually several. I also did some V-carving as a test. Works as expected as I have been running this setup on the Taig mill for several years.
Here is a picture of the finished carving. Two passes in 45 minutes. Nothing fancy, just some pocketing to give the HB2 a bit of a workout. This is not a keeper, but looks great.
Name and Callsign
Taig ER16 Spindle Added to HB2
Here is the first look at making the mount and installing the Taig ER16 Spindle and continuous duty motor on the HB2. This is the same spindle and head that I use on the Taig CNC mill. In fact it IS the head FROM the Taig CNC mill.
I’ll be running a project tomorrow to test out the set up. If all goes well I already have the TAIG order made out for a new set-up exactly like this for full time use on the HB2. This is lower power than other spindles used on the HB2 but much quieter. From my experience using it for wood carving on the Taig mill, I think it will be just perfect for most work I do. I can fit up through a 3/8 inch cutting tool.
The ER spindle is far superior to the one in the little hand router. The big difference is sound level and the fact that the Taig spindle is 1/3 slower and 1/3 the power.
One thing to note though is there is the opportunity to select 6 different speeds. With the belt drive I always get full motor power as the motor is always running full speed.
The change over from one head to the other is about 30 minutes. It could be less but the one bolt in the center of the back-plate mount is a bugger to get started. It is between two linear bearings and behind the lead nut. I taped the nut to the wrench to get it started. 🙂
I will also post these pictures over in the THMS web site. That probably won’t be for a week or so. I am also considering doing a sound video so you all can see AND hear how she runs.
Project Tessa
In case you missed this, here is a picture of a project I made on the HB2 router. I published it over on the Ramblin’ Dan blog too.
The layout was designed in Vectric Aspire and output for the MACH3 controller. Of course it is MACH3 that runs the steppers on the HB2.
Four files and three tool bits were required. One file cuts the outline using a 1/4 inch flat router bit. It leaves tabs for support so I did this first. Next was the roughing file again with the 1/4 flat bit in 1/8 inch steps. The third pass was the finish (detailed) pass using a 1/8 inch ball nose bit with very shallow step over.
The last file was the V-Carve for the name and date.
Total run time on the HB2 was about 2.5 hours. Speeds were 100 IPM for the roughing and 70 IPM for the finish. The HB2 handled them all just fine.
I actually made three runs. The first one is where the coupling broke, the second I spelled Tessa’a middle name as Daniel (Horrors!) and then the final fully successful ran you see here. At least I had a test piece to practice the finish work (and I did).
Three coats of shellac gave the oak the color you see here (no stain). Then the color painting. Last a final coat of clear lacquer.
I also used a table router to cut a T slot in the back for hanging on the wall.
Oh yes, the date is correct. Tessa is one year old!
HB2 First Project
HB2 has been brought to full functioning life with sounds not much unlike a trim router. I am kind of alluding here to a new baby cries when first born.
I am not one to choose an easy project for the very first run. What you see here is the Aztec calendar with a lot of detail. I set the design up in Vectric Aspire V2 and sized it for a 12 inch diameter. The process is known as V-Carving.
I used a 90 degree V-Carve bit. I discovered I should have used a 60 or perhaps 45 degree V-Carve bit. I would have deeper cuts and wouldn’t have had the dropout in several areas due to board warpage.
But all in all, not too shabby for a first run. I and HB2 can only get better. Enjoy the pictures.

Music To My Ears
My wife is a professional piano teacher but I am swooning over another kind of music. That other kind of music has four speakers and three channels.
What I am hinting at is the HB2 has come alive and is singing it’s stepper pulses. Anyone familiar with stepper motors knows what I am talking about. The steppers actually sing in the audio range as the pulses are being fed to them. The HB2 has four motors (speakers) and three channels (X, Y, Z).
The PS2 Power supply is complete and working as good if not better than expected. I made up all four XLR 5 pin plugs and they are a perfect match to the stepper motor cable I am using. I haven’t done the finish wiring at the motors yet as I plan to test for awhile.
I’ll get some pictures tomorrow and post here. Maybe a video too. I also need to do a write up for the web site. For today I just wanted to mark this milestone that the HB2 is now self powered. I could actually do some cutting if I come up with a hold down.

UPDATE 3/8/09: Pictures of the PS2 are now in the THMS website. Look under SITE TOOLS and What’s New for this entry: 03/08/09 – HB2 Construction Section 6, The PS2 Controller/Power Supply. At last the HB2 gets the power and brains to move on its own!
