What change gears?

[NortonDommi]

Hello,
I have been using this great program for several years now and cannot recommend it highly enough. It can now be downloaded at:

http://lathegears.software.informer.com/

It may take a bit of time to work out all your gearbox ratios but it is time well spent. Make sure you save your work and also save your ratios as a simple txt file. I had a major meltdown and fortunately I had the ratios saved on a USB stick,(lives in the lathe toolbox), for future reference.
I use it to work out configurations for threads not listed. It can also be used to work out missing gears so I used it to work out every new change gear needed to do every common thread as my lathe came with only one change gear. In a pinch you can use it to see how close what you have can get to what is needed, I start at 0.0000001% and work up until I get some hits for this.
Saves a lot of time doing mathematics. Enjoy.

Hi,
sorry to say that link just goes round in a loop with no download available

Hello Y-geo,
Sorry about that. I got the original then V1.2 from the author. After I posted I went and checked that download from 'software-informer' and 1: They want your E-mail. 2: Link doesn't work.
So here is the program. It is virus free and works great. You will need to work out what your lathes gear ratios are. Start with a thread that equals your leadscrew T.P.I. or pitch, factor in reduction,(if any), at change gears and work from there. Most gear trains tend to go in simple orders.
I have just reloaded onto a new computer that runs Windows 7 and got a request to save changes. I clicked yes and got a message 'cannot save to .ini file'
This threw me but click no and save all change at the 'Choose Lathe" section.
After installation go to programs file and you will find it at the bottom. I copied the Nuttal file, opened it in 'LatheGears', entered all my lathes information and saved. I then opened 'programs' and renamed to my lathes name.
It is a bit of work to start with but this is a great program.

*NOTE* I have made many attempts to upload this program and it is a no go. I will put into 'Dropbox' and post a link back here O.K?

Here is a link. I have just uploaded to Dropbox but am not familial with it so hope it works. If not PM me and I will send direct.

I downloaded it here, for my lathe, it's useless. I've an extra set of gears to be used, so this won't be worth a sod for my lathe.

Here's the info for the lathe I've got here, it's a Harbor Freight # 44859, if I'm doing something wrong, let me know!

Hello Murph,

I have found it to be an incredibly useful program over the last couple of years.

Work your way through the tabs starting at tab 1.

If your lathe is not listed then use generic lathe on tab 1.

Bill, I suspect the issue might be as much user error as much as anything else, maybe more so.

I'm going to get in touch with Vernon and get a little more dialed in for this.

I've also going to have to work on mounting a second motor on the lathe to drive the lead screw, as there's no backgear on this lathe for thread cutting.

Hi,
thanks for that got it down :-)

I got it to download, however it does not finish installing. Progress bar at 100% for over 5 minutes now.
