BOBL thanks for that , I get that far with GT but can't save as dxf if you can get it to please send me the file as I need to make a gear yesterday:>)  Dan Keith

BOBL, I forgot to mention upon opening GT I get this notice.  Dan

Hi:

  Hmm, that error usually indicates a video card driver thats old,..or a video card thats very old.
Does the program run after that error?

Art, yes it does and as I said I can generate the 250 tooth gear but can't get a dxf file.  Dan

[ArtF]

Dan:

  Hmph, generates fine foe me too. What module or dp did you need, Ill drop the dxf here for you. Did you ask Bob for a new license just in case yours is corrupted?

Art

Dan;

I also encountered a problem when I tried to export your dxf, what I got was only half the gear... Weird..  Maybe Art can shed some light of perhaps why that is?


Cheers
Bob

Dan;

I tried sending your license, however got an error from my mail server saying message cannot be delivered to the following recipients:
Reason: Illegal host/domain name found... Can you contact me offline so I can get this off to you..

Cheers
Bob

Art, I am making a drive for a solar heliostat and need a four foot dia. half gear with small teeth about 1/4 or 3/8 inch nothing critical. Also about a 2 inch or so pinon, again nothing critical. Thanks Dan

[ArtF]

Ill leave the pinion to you as I ditn see tooth cnt..but heres a dxf of a mod5 245 tooth radius of 2foot
so 4' dia. Seems to work fine here. Youll notice at that size the teeth are basically pressure angled
straight teeth..thats normal as the radius to tooth ratio is very very high..

Art

Thanks Art that will get me started. I salvaged several hundred high quality laminated mirrors ,4'x4' from left overs from a large array solar project and need to do something with them, so I will be making some gears to track the sun, haven't nailed down a design yet but I will post pictures as I proceed.  You need a heliostat to shine some light on your projects:>) Thanks a lot Dan

[ArtF]

Dan:

Ahhh, I see. Probably be easier to simply cut half circles 4" in diam..then attach a wire rope to each half end so it runs on the perimiter.., and use a motor to drive the wire thus rotating the "gear".. Save cutting a lot of teeth, and just as accurate. Also stops weather from affecting the teeth as there are none..

[dansfoundry]

Sounds interesting can you draw me a picture? I'm a visual guy:>)  Dan

[ArtF]

heres a dxf...dunno if you can read it. Think of it like cutting a barrel in half, mirrors go inside barrel, rope gets tied to edge then wound round the back of the barrel and tied to other edge., If you put a pulley on that rope the barrel will rotate with pulley..

[dansfoundry]

Thanks Art I get it ,I like it, I will let you know how it works, Dan

Hi All:

  Just a note to say thank you for your patience since last release and your kind comments on it. Ive
  been taking a couple of weeks off from development to use the softare myself to build a project.
  As a developer the greatest trap you  can fall into is not using the software because your too busy
  developing it. Ive been finding several  things wrong, or inconsistancies or weirdnesses that it takes
  me awhile to build anything as I keep having to recode to fix things. That, of course , is the whole point,
    Im much more likely to find rough edges if I use it myself. Im building a chrono escapement kinetic art piece as a test ,
  and Ill make a video as soon as its ready...provided I stop finding things to fix. :) . Crash reports are way down
  so I think the main kernal is starting to play well with the various modules. Youll see more fixes in next release.
 
    Ratchets and geneva's will be the next modules to be developed,but things such as calculators and such will be done in parallel.
   
    Just a progress update.,.
 
  Art
