Making My First Gear

<< < (2/10) > >>

I'm glad the spreadsheet is helping Don!  I'm going to need to use it myself when I put the 60 hole circle in my SB pulley....

Definitly set that bugger back up and cut some more teeth ....nothing to lose, and you'll get a better feel for the whole set up.

Maryak:
Don,

Sorry to read about your Oops. If I am looking at things correctly, you are starting the cut from the back of the blank, so it's difficult to  see what's going on until it's too late.

May I suggest you either turn the cutter 180 and reverse the rotation, or start the cut from the other side of the blank,  or put the RT on the other end of the mill table.

Edit:

Lastly, prove your indexing.



Hope this helps

Best Regards
Bob

Thanks I will finish the gear for a test run. And I do have a habit of turning the dial by the collar instead of the crank and it is a slip collar. I also have a video by Swarfrat on the RT. this is how I learn to read minutes and seconds.

Don

Don1966:
Thanks Bob I will try that.

Dave the spreadsheet you gave me is great. I still struggle with setting the seconds they are so close. Hope next week I can try again. The is the 34 tooth gear for metric conversion of my Myford.
