What change gears?

**NortonDommi** · Sep 15, 2017, 03:55 PM

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?

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

Hi,
seems that although the software says you can custom install the program where you want, it it fails. However if you leave it to DEFAULT install it will install where it says it will you can then move it to where you want it . yet to check it thro but so far ..........................

Hello all,
I am sorry that some are having problems. I have been using this program for several years now and find it invaluable as I repair old machinery for a hobby and come across threads that most don't know exist. I posted in the spirit of this site as I believe that the program will be of use to many.
To Murph1090, have a look at what steamingbill has written and also my reply to Y-Geo. I have no idea what a Harbor Freight #44859 is and when you say "no backgear" ??? If you do not have a gear train to the leadscrew why have you got extra gears?
azbrewer something that had me wondering what I was doing wrong for many hours when I moved up from XP was that now there is a default with downloaded programs that means you have right click on the program, properties and at the bottom click on 'unblock' and then 'apply'. This applies to just about every program and NO PROGRAM will install until this is done.
I hope that the aboves answears,( mine and steamingbill's), will help resolve any issues.
Best regards,
Barry.

Barry, there is a gear train from the lead screw to the drive, the backgear is to reduce the drive speed only for threading and the like. One is independent of the other completely.

harbor Freight lists its lathes by SKU number, #44859 is the designation, and if you go to their website, you can see the manual that goes with it.

https://manuals.harborfreight.com/ma...4999/44859.pdf

The gear train is rather different from what's shown in the program, and I have both here, the program in my laptop AND the app on my smartphone, not like I haven't spent enough time reading the instructions.
