Cutting Wing Rib Forms #118 - Oklahoma USA
What is the size of of the angle iron that is used for the cross rails. I do not see a specification. It looks like maybe 1/4", but I am not sure.

Also, what is the meaning of the red hatching in the longitudinal direction I see in drawing 10-10-246-D. Is that some extra length? If so, how much?

Never mind, just as soon as I post, I find what I need at M1-10-110-M.

Learnin the ropes - Oklahoma USA
What is the english equivalent to 100mmx50mmx2mm rectangular tubing.
The closest in 32nd's would be 3/32, but I see nothing like that. |

the closest equivalent would be 2 in by 4 in by 1/4 in. Also, try asking all your questions in the same thread, as each member is only allowed one build thread per machine.

I will be sure to keep keep everything in one thread. I am sure there was an FAQ I was supposed to read somewhere about that.
1/4in is almost 3 times the thickness of what is specified in the drawings. That would seem to add a lot of weight to the gantry. If I needed to go oversize like that, I would think I would be better off with 1/8 wall, if it can be found. I also just noticed in the similar thread listing, http://www.mechmate.com/forums/showthread.php?t=232 Too bad that did not pop up before I created this thread.

DB - goto the forum main page and look at the sections. In each section there are sticky threads at the top. Read those. Then look in the MechMate's already cutting area and sort on views and start reading through those threads .... did I mention a lot of reading

On page 10-30-455P I see a reference to a higher drawing 10-30-400 W, but I can not find it in the supplied drawings. Perhaps it should be referring to drawing 10-30-420W?
I am also guessing that 10-30-455P should also indicate that 2 of these should be made, based off of what is in 10-30-420W? As a background. I almost always make 3D models first. That way I know exactly what I need to do before I go into the shop and start cutting metal. I almost always find myself regretting it, when I do not go through this process. 2D drawings always have little ambiguites and errors. I like to find those problems before I get into the shop. I will probably have lots of other little "nitpicks" and questions as I go through this process. |

Going over the z-axis drawings I notice what may be a typo.
Drawing 10-40-014A shows as being a 250mm slide, but in the drawing spreadsheet at the beginning of the plans, it shows 10-40-014A as a 350mm slide. 10-40-000 shows as a 250mm slide in both locations, so I am assuming that one is correctly labeled. |

What release of the drawings do you have? If your referring to the TITLE block in both sets the 10" refers to the stroke distance of the plate, not the actual distance. Use 10 40 330 and 10 40 334 for true length reference of the slide that fits your build requirements. The option allows for an additional 100mm of z-stroke for those needing the extra travel. |

I do not see an overall revision number for the plans, but I downloaded them from the paid area about 2 days ago.
|
#14

|

Then you have the current set.
|
#15
|

Ok.
The two drawings I am referring to are the assembly drawings for the Z-Slide Assembly. Both drawings say 250mm. In the drawing index, one is referred to as 250mm and the other 350mm. |

Clearly a typo...just know that you have 2 options. Funny, your the first that I know of to pick that one up. With almost 100 known machines, I am certain that little type won't derail the build.
Good luck and don't pain over the drawings - pictures in the forum builds are far more educational. A good pictorial is JR's build. |

Do you have a link to JR's build. When I do a search I find no user with that name.

See Drawing problems and revisions required, considered and intended . . . . .
I seem to remember this one listed before, but that would be right place to list drawing problem issues. |

What are the alternatives to using Antek for the power supply or transformer. I tried emailing them today to get some information about one of their power supplies for a non Mechmate project and was not very impressed with the response. In addition I have seen some posts on this forum about some difficulties when ordering from them.
As a result, I am rather reluctant to place an order with them. |

The power supply transformers technology is over a century old.
Just bring your specs to any transformer people. Google is your friend... |

DB - I buy from them all the time. They are a small company but make a solid product.

I order 1 or 2 a month from them without issues....along with the sister company Par Metal.
Jon is a good guy....they just have a very busy small business. No worries. |

DB,
I had occasion to call them a few times for some information and bought a fuse block. I find them to be very responsive. Never tried e mail. |

Thanks for the feedback on them. I will go ahead and give them a try, but it sounds like dealing with them by phone may be better.

Where does the V=32*sqrt(L) formula for max voltage come from? I see it quoted a lot, but I can find no reference to how it was derived.

Can someone point me to some pictures of already wired control boxes.
I am trying to get an idea of how the wire is organized and how the interconnection between components is done. |

Thanks Alan,
That is a great looking layout. Is there a standard name for the termination blocks and cable connectors you used? |
