Big BOOM – II

This week started with a literal BANG!

Lightning again struck my house here in Frisco, Texas. This is the second time. First time was Monday June 29, 2009. A little over 11 years ago. Search “lightning” (upper right corner) on this blog for more information. (Yes, this blog is much older than ten years.)

This one was on Sunday morning August 30, 2020. About O500.  One hell of a wakeup for a Sunday morning. (Words carefully chosen…)

The bolt struck my nearly 20 year in-place vertical amateur radio antenna. Just outside the bedroom window. The vertical antenna is mounted above the lowest corner of the roofline on […] Continue reading » Big BOOM – II

Giant Suck

Raw Sewage

I have abandoned Facebook for (I think) the third time.

FB has some good points and I enjoy keeping in touch with “real” friends and family. I do not judge my self-worth by how many long-lost and stray-cat “friends” want to join me.  My real friends know how to otherwise keep contact with me if they desire.

The political climate and vicious personal  attacks have driven me away again. The fraudulent advertising is also no attraction. There is more raw sewage in Facebook than I can withstand. I don’t desire the exposure when it is so easy (and hard) to just turn it off. 

It […] Continue reading » Giant Suck

Creative Manufacturing Art and My Personal Philosophy Best of Both

I have one outstanding way of creating wax masters for lost wax casting. I use a high-speed spindle (up to 25,000 RPM) on a Taig Micro Mill. If I can draw it properly, I can machine it in 3D.

The limitation is the 4-axis ability of this machine. That doesn’t sound like much of a limitation to most machinist. 4 axis means X, Y, Z movement with an additional rotary A axis. There is a huge amount of work that can be accomplished with 4 axis milling.

But there are some designs that can benefit from additional movement freedom. […] Continue reading » Ramblin’ On

A20M Repair

The A20M is my Geeetech (brand) dual color 3D printer. I also own and operate a Geeetech A20T which is a triple color 3D printer.

The new dual extruder

The A20M has been an excellent quality printing output. However the dual print head as been a fairly serious issue. I just installed the second replacement printhead so it is now running on its third.

The second head is identical to the first but the third is anodized black (see pictures). Geeetech has not said what is different on the new black extruder. (print head).  They do claim it has been improved and I suspect a few internal […] Continue reading » A20M Repair

In Flanders Fields

It’s Memorial Day, May 25, 2020 Used to be called “Decoration Day” in the USA when I was a kid. It’s a day we honor those who died in war defending the principals of freedom the USA deems important enough to defend to the death.

Sometimes war may be more than just about freedom., but that is another story.

Today is not to argue the reasons, but to honor those who died. 

There are many that serve this nation and face the risk of death. I am one. But today is not about serving. It’s about those who serve and pay the cost with their lives, 

A close second […] Continue reading » In Flanders Fields
