Gear Cutter

Well I've got to start somewhere, I've been lurking around here long enough.
Here is my approximate involute gear cutter, turned down from some un-known steel from the calculations from this siteInvolute Gears

Attachment 4226

It was then pack hardened for 2 Hrs. at 1800* F And the teeth honed on a diamond lap.

Attachment 4227

Set up in my homemade knee mill (Witch will be another post as soon as I get a few more pics.)

Attachment 4228

And the final gear.
Attachment 4229
Although I believe I forgot to add the extra for whole depth plus clearance it does run on the lathe, but a little noisier than the other change gears.

Nice work and looking forward to some pics of your home made mill.

Your post caught me by surprise as this post is a couple years old! As to the mill, I used it for a little les than a year never really completely finished it and got offered enough for it by a shop that wanted a heavy-duty drill press with cross slide table that I was able to pay for a smoking deal on a used mill taken out of service at the Intalco Aluminum plant here.
I think the only picture I have left of it is the one in my avitar

The Involute Gear Cutter is something I am going to try very soon. Thanks for posting.

On a side note you use the "*" for your degree mark. There is a very special way to get the real degree mark and I'm going to let you in on it. Hold down your "ALT" and punch in 248 in the number pad to the right of the keyboard. It will show when you let go of the "ALT" key- °

Nice to see this thread again...Great build!

Alt-0176 is what I have used for years °¿°. :p Thanks ncollar, saves a keystroke for an old ASCII guy. Δ² ∙ Ωⁿ±Ø ≈ ∞

Here is a table for others enjoyment and use. This website is pretty good too.

Thank you so very must for the site. There is so much hidden in the keyboard most people haven't a clue about.
Again thanks

Thank You Nelson! Hadn't explored Alt codes much but will add to the repertoire. Cut and paste works but it's nice to play with the original emoji's sometimes. :p

the ALT 248 is calling an extended ASCII characters.

Look at this page and you can see other Characters

And I thought I knew something and you all just keep adding to my brain. Now to remember it and at my age that seems to be a problem.
Thank you

Pretty much all of it started with ASCII because it was built into the keyboards and bios early on to handle (display/print) the alpha/numeric we use to communicate with, but that changed as computers went beyond 256. Actually Alt Codes came from MS trying to preserve the original and expanding it with bigger processing bytes/words (8, 16, 32, 64...). Now there is ASCII, ANSI, HTML & Unicode and maybe a few in between all being brought into Unicode for fonts and escape derivatives...but it all goes back to binary and hex.

Yes,

My first Computer was 486SX and i "discovered" the ASCII and it was a lot of fun making images of BBS Forums. God I'm old.

Yes, you are getting there. I started with an old CPM 8" floppy, then an Osborne, a Trash 80, a Commodore or 2, and TaDa an Original IBM XT with a 5mb Bernoulli box and 2 360kb floppy...in like flint. Still have the XT, now with a CGA monitor and a video card the size of a mother board now days...goodness knows why...maybe the Gkids will get a kick out of it. Plus I still remember the original BBS/file server/cwis using Gopher and some basic and Edlin...guess I could let that go now, but BBS'ing was a lot of fun on 300 to 56kbaud dial up. Guess that makes me ancient but had a blast along the way. :p We've come a long way and harder and harder to keep up especially when CRS sets in!

If you have a 32 bit version of Windows, there's a tool built-in for working with extended codes. Search for the executable "charmap.exe". It has numerous character sets and you can select the character(s) you want and copy them, then paste into your document.

Bonus hint:

The Windows search function is severely brain-damaged. Do yourself a favor and get a real search function. I can recommend Ultrasearch...

It's fast and thorough and free.

Good point Marv on using Charmap and it is available in 64bit Win7 Pro. I programmed my Calc Button to a popup with Charmap, Calc and UnitConvert a great little quick converter with a ton, plus you can add custom ones not in the library and set the decimals.

I miss XTree (note:West Coast Computer Faire and sold for $39.95...where I got it about then and Gold 3.x later). Best ever imho. You could view in lots of formats (ascii, hex, etc.) and edit files...move, copy, zip...Just the best. Ztree is around and decent search features. Had a look at the Jam stuff, may give the "Free Ultrasearch" as a test towards either their TreeSize Pro or Personal...look decent, compared to FM/Win Exploder.
