If you ever need to make a spindle workstop...
... bicycle handle bar nuts fit the 7x bore.
I just tapped one to fit some 1/8" threaded tube used for lamps (straight 1/8" x 27 pipe), bored the other out with some slop to allow it to move up the wedge. Welded a 1/4 x20 coupler to one end and used a pipe nut (modded to straight 1/8" x27 thread) as a jam nut. The plastic 1/4x20 wingnut sets the depth stop. The aluminum spacer gets it thru the change gear door (I have a hinged door on mine with a captive thumb screw so it's a bit longer..) pics: |

Re: Axis designations
Well I wasn't entirely disagreeing with you.
The emphatic No no no no, certainly stirred up some emotion.? (Big Smile)
But after following this thread of posts I can see now there seems to be a "standard"?
It also seems to follow the mathematical norm.
Now would someone mind telling/informing a few of the would be Autocad users?
However I thought the right hand rule was for electronics only? Lenz's Law?
Or did he borrow the term from the Mathematical community?
Thanks for the correction!

There are LOTS of excellent reasons never to swap the designations. For cnc use especially. There is tool tip compensation, tool wear compensation, css (very very important), feed per rev, and so on, all of which are always based on using std nomenclature for the axis. There is a very easy way to remember the axis designations. The lathe is a horizontal mill. You stand at the TS and look towards the HS. x is right, y is up, and z is towards you. (Also known ass Right Hand Rule [follow the thumb]). If you use other non std axis names, and ever get to use someone eless, anyone elses setup, this can easily come back to bite you.

"When I read that "wondering if there is a way of making one" I thought
someone must have made the first one, eh? " OK if you are in the mood of splitting hair over English language phrases then let me clarify by rephrasing the sentence -- is there is a way and means for the hobby individual person to make a rotary broach holder (as oppose to the sophisticated industrial production line equipment that most hobby users lack access to). Now Morton you see how this could be cumbersome to explain when we try to spit hairs rather than using common sense (seems not that common ...for some). in any event I guess it will be allot easier for me if English was my first language...would you like to try it in a different language maybe that will clarify the issue. |

Re: Axis designations

Correct and the reasons for keeping it standard. As
I mentioned earlier, it is easier to think of the axis in relation to the
workholder, as he outlined above. Then it doesn't matter what machine you are
using, we all talk the same language.
Cheers.

Re: 100mm spindle source in US?

lathes I know of.
And one of less than 10 finished - scratch built cnc latehs are very rare. Equally rare are scratch built cnc mills.. I know of about 5 in total. (Mills as in of and for steel, with milling spindle. Not routers for alu). ? |

Re: Real Bull 7x14 lathe questions?
Not sure of the price range you guys are looking at,but at 1150.00 my 10x22 from grizzly is several times the lathe that the 7x12 it replaced. I lost the 7x12 to thieves last winter, and got the 10x22 as I kept seeing the 7x14 for around $800+ with a bit less than what the 10x22 came with. The wife wasn't so happy with the extra cost, but now that i'm getting used to the bigger I'm glad I got it. It comes with 5" 3 jaw, 6" four jaw chuck, face plate, steady rest, follow rest, mt4 center, mt3 center, plus a little tool box to hold the tools in till you get a bench made. I still miss the 7x12 tho, it was my first lathe and I had lots of fun learning with it.

Re: seperating workpiece cyno
I saw a few weeks back guys using cyno superglue to attach small pieces todress them up,someone was turning both sides of a narrow washer, I cant rememberhoping the cyno will break down. Like other said heat works well. Most adhesives soften or break down about 70 degrees Celcius (~160F). This is very handy to know if you want to get a decal or similar off without damaging it. I usually put them in the oven at around 100c (212F - boiling water temperature) and they'll peel off easily enough. Works well on things like the little surrounds you find on ignition locks. Plastics are ok at that temperature (acrylic melts at 140C), I once removed a thin aluminium bezel off a plastic watch, powder coated it and put it back. Tony |
