"One Perfect Part at a Time"

Workshop

Just Add Water

The water cooling has been added to the high speed spindle through the red tubes in the picture. This is phase one where I will be using a reservoir with a sump pump behind the bench.. This should let me operate for maybe an hour or so. I don’t have any idea how much and how fast the water will warm.

The next step in the water cooling will be to add a closed loop system with a radiator to move the heat out into the ambient air rather than store it in the water tank. But first I need… Continue reading

24K Spindle Progress

The parts arrived yesterday. Exactly as shown in the previous post. I placed an order for some four conductor cable for the wiring between the Variable Frequency Drive (VFD) and the spindle motor.

I needed to see the clamping size of the spindle’s electrical plug connector. I didn’t want to select and order a cable that would not fit. The cable is on they way to me, so I created the adapter I needed to mount the new spindle on the Taig Micro-Mill.

The picture shows the results of my work as the spindle is now nicely mounted on the… Continue reading

High Speed Spindle

Here in the RD workshop, consideration is being made on adding a one horsepower 24,000 RPM spindle to the Taig CNC Micro Mill. The standard spindle is a belt drive one quarter horsepower unit with a top RPM of 10,000.

The standard spindle and drive is quite adequate for most of the milling work the micro mill is asked to produce. The primary use for one of my mills is wax carving with as small as 0.003-inch milling bits. That size mill bit can best operate at the 10K RPM and higher ranges.

I did some comparison of speeds and… Continue reading

Dimensional Decision

I am presently using two very good 3-dimensional CAD programs. They are Autodesk Fusion 360 and Robert McNeil & Associates Rhino3D. I am at a decision point on which one will be my standard go-to drawing program.

I have had the longest association with Rhino. I started with version 3 and version 6 has just been released. Major version number upgrades must be purchased. That’s why I am at a decision point.

Fusion 360 is free for users like myself. That is a major advantage. The Rhino3D upgrade is $375.00.

It seems like a no-brainer to stay with the… Continue reading

What Excuse?

Ramblin' Dan

Ramblin’ Dan Today…

I try not to go on guilt trips. The view is depressing, and it doesn’t solve any problems if I am busy blaming myself. I can be guilty of many things, but I don’t have to ride the train… Uh, oh… speaking of trains. That reminds me…

I am guilty of putting my live steam and model trains fun on the back burner. Heck, there are a lot of things back there, just simmering. Some of them may be stone cold… Well, that’s the way it goes. I can’t feel guilty about not being able to eat… Continue reading
