I'm excited to follow along with your videos. I love how you are so calm, you explain the design in great easy to understand details. I can't say this enough to you, but I thought of a new title for you, the Master Professor. And I mean that very seriously. Thank you so much Jim.
I'll be looking forward to this project. About 40 years ago in my first year of machine trades I made a gear set which took alot of math figure out the placement of the gear teeth. The cutting took had the involute curve going into the cutting tool. It will interesting to see the math involved in making of the involute curve.
Hi Jim. I worked in Unigraphics CAD & Design for years but not getting how in DesignSpark, at the 8:47 point you get x & y coordinance to rotate counterclockwise 90 degrees. This is after selecting the line, then going to MOVE TOOL, then move the coordinance to the center.
Jim, great videos but to save reinventing the wheel (or gear) is it possible to get a copy of the excel spread sheet you used to work out the element lengths?
I'm not sure but it is obviously a parameter that has been determined by some empirical means for calculating the value of the dedendum. As I stated at the outset, the video is not for the purpose of explaining the theory of gears, but to show how to model a spur gear in DSM. If you want to know where 1.157 came from, I suggest that you do your own research into gear theory or contact Carter tools.
I am appalled you are using imperial gears and not metric. Quite literally nobody uses imperial style gearing calculations these days. Everyone uses module not DImaetrical Pitch.

Thank you for your kind words.
Very good. Very useful way to understand DSM. May be complicated - but with DSM and CNC machines of the day quite achievable.
Absolutely.

I think I've figured it out. Got it!

Do you know if they are EVER coming out with an APPLE version????
Suggest that you ask the DS people
They've never mentioned an Apple version. Why don't you nag them and ask.
I am studying this..BUT.. where did the " 1.157 " come from??

That looks too complicated for me lol
I've done many more basic DSM vids. Why don't you cut your teeth on those?

I started following his instructions until he got to setting the units to Imperial. A shame, it looked very good up to that point.
Way too complicated for mere mortals like myself, skipping to the adds!
If you perservere there's no knowing what you can achieve.
This world is full of 3/8 yards or inches... utter useless
