As the sun gear is 10 teeth, there is certainly a positive addendum modification, and certainly also for the planet gears, These gears must so be cut with a generation machine, or a special drawing made for a fly cutter.

You can read my articles in MEW about drill sharpening (the Van Royen is discribed as conical clearance). Issues N° 245, 246, 247. Issue 251 for small drills, and issue 256 for web spitting. I'm still working on the subject for further articles.

Best engineering wishes for 2019 with the help of some snap rings!

This process was also described in "post bag" in the january 2004 issue of ME.

Have a look at the article "machining shiny knurls" ME issues 4543 & 4545 (sept and oct 2016)

Happy new year and best wishes with the ER25 collet set!

Now a mulltipliying spindle using the same mechanism.

Hello Neil

Here is a blue print copy of a 1981 exam for driving a potentiometer.

The DENAL density is 17.5 (19.3 for pure tungsten). The copper/tungsten alloy (used for EDM electrodes) density is only 14.

J Maurel

Surch for DENAL on the web it's an alloy 93% tungsten with iron nickel and cobalt I used it for making boring bars (for low vibration) it's machinable while tungsten is not, but you must use TC taps (I killed HSS ones in this stuff).

What is fondamental for involute gears is the « base circle » . Visit my website: **LINK**
Watch the following video:
Begin by the seventh: “The bad gearset” next “ Involute generation from pulleys and belts” next “Involute mechanical behavior” next “Involute and rack” next “Involute gear animation” next “mutiteeth gear”.
I think that this will give some explanations.
I can write an article about “addendum modification” that could be of some interest as many model engineers have made the “jacob’s” gear hobbing machine, if Neil is interested in?

Look at this book:

I've contrived an attachment which solves the problem of tool jamming, just wait for some monthes as this attachment will be described in MEW.
J Maurel

you must buy the gear pair as the angle between the gears axis is involved.

Happy new year and best worksop wishes with spur gears for 2017.

Look at my article "an HSS tooltip holder" in MEW N°239 issue (march 2016).

J Maurel

Happy new year with ball bearings for 2016

Look at the article: "The rumbling tumbler" in the Nov/Dec 1994 issue of MEW.

Hello

You'll soon dicover that honing is boring, so why not try boring instead of?
