Always Random
Just worth saying
4 Axis Spruce-up
- Centering Axis
- Looks Good
- Chuck Adapter
I have found a good project for my 4 Axis CNC mill and also my Rhino 5 software. If you have read recent posts I have mentioned I am pursuing carving some small bells from wax for lost wax casting. Here I am re-configuring my original Taig micro mill back into 4 axis operation.
I need the tailpost to be able to slide into any length position I need. The stock Taig slotted table is perfect for that. I don’t need the multi hole set-up table for 4-axis. I set the rotary table up so I can just slide the tailpost against the back of its slot and it is in perfect Y alignment. The height is taken care of by the shims and the small adjustment in the tailpost itself. After this set up it will be a very quick reset for the tailpost.
You can see I have placed a Chuck adapter in the middle of the table. I will use that (with a chuck) to hold the wax cylinder as I mill out the center of the bell.
I have a few seconds of video I made of a dry run of the 4-axis profiling run. It makes some interesting sounds as the X axis is moving very slowly and sometimes “jiggling” a bit. Not sure why, but it is playing that CNC music. You will have to imagine all the missing parts. Hey! Just do it! 🙂
Vertical Lathe
Maybe not true vertical, but the X tooling moves in that direction…

George Moorehead hails from Gig Harbor, Washington and is currently in the process of setting up a new workshop in his home for his retirement years. Sounds like we share a lot in common. This is a mod George made to two machines to create a CNC vertical X movement lathe. Interesting!
Thanks for sharing George.
TEDEX Forum Phoenix
UPDATE 4/26/14 Registration Fixed (see comments)
Here I go again… (enter TEDEX in the search key word box)
I like some forums. I like the ones that feel more like a club membership than a forum that wants to dominate my life. Well, actually being the administrator or a moderator of a forum can dominate one’s life, if you let it.
The forums I am attracted to are the ones that stand alone and are not associated with one of the big mega forum providers. The big boys fill their forums with advertising and sell my viewing habits to product vendors in order to pay and make a profit from providing the service. That’s bad Karma for me.
I don’t run any of my websites to make money from views. Maybe I am foolish but it is the way I like it.
Once again I have resurrected the (hobbyist) TEDEX forum from the ashes of cold storage. All the old files are still intact. I left the door open for 24 hours and almost immediately it was attacked by a swarm of Botflies pumping commercial spam into my forum in various forms, mostly pill pushers, with about 25 new posts.
I immediately tightened up the registration and it is still open, but registration now needs more effort. New members need Admin permission and must wait for it. Posts are limited for the newbie to prevent flooding. The latest update of the forum software added some nice tools for spam blocking. Unfortunately spam is a fact of life in today’s reality. If a request looks like spam, I won’t even open the door. Post spam in my house and I will knock you out. I have the can of RAID at the ready! Ha!
I am considering several options for adding… Continue reading
The Lists
I used to post blog type thoughts and comments in The Hobbyist’s Machine Shop web site under the tab names “Shop Notes.” I was scanning that menu just a little while ago when I was reviewing the web site. The effort to publish those notes has been superseded by this site. The “Shop Notes” has become what is this blog today.
I kind of miss seeing all the topics listed in one simple list. So I thought the blog site (here) needs to have a list like that. I just made some changes in the right column that makes the posts and pages a lot more visible.
I think it looks good so it will stay… until I make another change. <g>
Take Your Best Shot
There is a HUGE amount of BS on the internet forums about proper size CNC hobbyist machines. Internet opinion forums and blogs, because they are unregulated, have become impossible for a newbie to determine fact from reading someone’s personal agenda. Don’t trust anything you read including what I have to say. Just take what you read for what it may be worth to you.
Every brand, design, size and cost of a machine has it reasons. Unfortunately, what amounts to urban legend has driven the uninformed hobbyist to believe there is always better quality available for a lower cost; the best for the less. This is while some bloggers preach that only bigger is better.
There are products designed primarily for a low cost reason. There are products that are produced primarily for a quality reason. Then there are products produced that look at both those factors and are made and sized to do a particular job and do it without failure with the correct level of quality.
Many hobbyists are restrained by budget. Therein lays the problem. There are poorly designed machines sold at very low hobbyist prices because it is a well defined market with newbie’s that have limited money to spend. I have written about it for many years. Some hobbyist choose price over quality and undersize the machine capabilities (because of price) for the purpose (work) they want the machine to perform.
First step is to clearly understand your intentions of use.
I personally own several sizes of hobby grade machines. They are excellent for my purpose and how I use them. I know their limitations and don’t kid myself into thinking those limitations don’t exist.
I have (and sell) Taig machine tools. I have many-many hundreds of hours of operation on my Taig CNC milling… Continue reading
