This is wonderful , I tried it and it worked . thanks alot for your video and explanation which made it easy to draw the gear . it helped me alot , thanks again and God bless you
I downloaded the software, scrolled for the standard sprocket parameters and picked the #40 sprocket. The #40 sprocket roller diameter is .3125 inches. Thats correct according to the Machinists Handbook, but the software creates the dxf sketch with a .3125 diameter roller pocket also. That would work in a perfect world, but there is endmill push-off, machine tolerances, chain pitch tolerances, etc. that would prevent the chain from working on the sprocket. Machinists Handbook explains. Later,RT.
Sir Rick Taylor, I Would like to draw 16 teeth - 3" Sprocket with roller dia 1.25" for CNC programme(For teeth cutting) Please tell me Can I follow the same instruction?
Sir as per my info. 1.75" Std. roller dia. for 3" pitch sprocket , we already cut this sprocket on milling 1 year b4 but we want it cut on CNC milling so ple. tell me can I Follow ur instruction?
Can u specify the dimensions of the holes please specially the hole that 21 tooth #40 is written on it? Are the dimensions of the hole of standard size? Can u send the link of the file or the site u used to make the sprocket? I remember seeing on the net but cant remember where

Thanks a lot for this helpful video! All loves from India.
Rick,
Very Informative Video!!
Do you know what is the related ISO standard for making a sprocket (either forging / milling)?
Unfortunately I don't get the explanation. Would you be so nice to do another video on that with a spoken more detailed explanation??? Thanks a lot

NEED TO MAKE A SPROCKET HAVING 162MM PCD, 6x42 MM(DAIAxPITCH) OF CHAIN AND 6 TEETH. CAN U PLEASE HELP ??ME OUT
Very useful Video Rick!! Could you shed some light on the ISO standard used for designing the sprocket ?

1.25" roller is too big for that size sprocket, especially with 16 teeth.

no
@FdelaOpera , yeah, i have other videos that demo drawing TRUE INVOLUTE internal and external spur gears. Good luck.
how did u draw spokes and the bore?
I used the LINE command, the FILLET command, the CIRCLE command, and the RECTANGLE command. Then, I used the TRIM command.
Can u specify the dimensions of the holes please specially the hole that 21 tooth #40 is written on it?
Are the dimensions of the hole of standard size?

ANY ONE CAN TEACH ME HOW TO DRAW A CIRCLE THAT INTERSECT THE THE LINE
sir use circle TAN TAN TAN Method
nice
Or use sprocketeer and generate the drawing in 20 sec :p
