Could Add Pic of Form Tools[edit]

Hi, I'd be happy to take some pictures of form tools and add them to this page. But I think I need some instructions on how to do that due to senstive copy right issues. Since they are my form tools and my pics, this won't be a problem. Thanks. KAS 22:16, 12 June 2006 (UTC)

Its fairly easy to do. http://en.wikipedia.org/wiki/Wikipedia:Uploading_images

Use the upload file button on the left menu and upload the image with the proper copyright options. The image then becomes its own page which you link to in articles where you want the image to appear. Try to keep the image size small (in keeping with clarity) so it will load fast. You can click edit this page on any article and read the script used for any image so you can see how others have been done. For instance this is the image of my tools as used in the article

Various tool bits, carbide inserts and holders

Click edit this page to see how the script was written.

Hey Motorhead! I uploaded my first image thanks to you. I saw that bike you built and it reminded of the flick Easy Rider. So in salute to your cool bike, I uploaded a form tool that I made, and it makes Shift Knobs for High End Bikes. KAS 07:35, 13 June 2006 (UTC)

Glad I was of some help!--=Motorhead 00:41, 16 June 2006 (UTC)

Would Advise Form Tool for Another Edit[edit]

There is a problem with the last edit of deleting Brown and Sharpe Single spindle screw machines.

http://en.wikipedia.org/w/index.php?title=Tool_bit&diff=58442159&oldid=58365698

This because both Swiss style machines and Brown & Shapes are single spindle machines but very different. Many times SWISS style single spindle machines single-point turn (such as the Star), and form tools not used that frequently. The way the new edit stands, the information on Form Tool is in error. It needs to be noted that Swiss machines do not at all work like Brown & Sharpe style type machine. For example, on the Swiss machine the material is regulated through a spindle bushing while the part is being single-point turned, where as on other machines similar to the Brown & Sharpe the part is stationary in the collet while the operations are usually carried out with form tools on the front and rear slides. Another way to say it would be that on Swiss style machines the material is fed into the tool, whereas on Brown & Sharpe style machines the tools is fed in the work. The point, the brownies make frequent use of form tools and the Swiss style machines do not. I think in order for the reader not to be miss lead, the essay on Form Tool needs to be re-edited somehow. Just my input any way - feel free to ignore <smile> KAS 07:14, 16 June 2006 (UTC)

Okay, I think I came up with a quick fix. Nice editing of the article by-the-way Will! It's broken up and easier to read. KAS 08:12, 16 June 2006 (UTC)

Two Roller Outside link?[edit]

What does the outside link of "two rollers" have to do with my edit of the BOXTOOL? It looks totally misleading for someone that wants to understand the boxtool. Advocate4you (talk) 08:17, 15 November 2009 (UTC)

It shows an example of that general class of tool (roller backrest traveling with its tool, one complete unit at a turret station). The tool illustrated (old J&L) probably isn't exactly like the one you had in mind when you made your edit. A different example of the same principle. I don't mind moving the link out of that sentence. I will go do that and turn it into a proper {{cite book}} ref. — ¾-10 00:24, 16 November 2009 (UTC)
Done. — ¾-10 00:35, 16 November 2009 (UTC)
Thank you. Picture of Boxtool added. Advocate4you (talk) 07:39, 16 November 2009 (UTC)

Parting tools[edit]

In the first picture, the tool on the very left appears to be a holder with a parting tool. It is not the straight sort that most people seem to use but is right handed. What is the purpose of this? When would you use it rather than the straight tool holder?

That type was formerly in common use on manual lathes with a rocker-style toolpost on the compound rest. The problem that it solves is that you can't always do your cutoff up close to the chuck if you're running that style of toolpost setup with a straight cutoff tool, because the compound wants to occupy part of the same space that the chuck is occupying. Especially if you have the compound set to 29° or 30° for threading and you want to throw in a cutoff operation without disturbing its setting. Another way to think of it is that it keeps the cutter in the same location while it pushes the toolpost and compound off into the tailstock direction, to keep them away from the chuck. I made a little sketch to illustrate. This is all obsolete commercially, at least in G7 countries, because rocker toolposts are not a good way to make a living anymore here (CNC turning centers have turrets, and the handful of manual lathes that remain in a commercial shop usually use quick-change toolposts with dovetail holders, which have more rigidity and quicker, easier tool change with no resetting of tool nose height). But hobbyists still get plenty of happy use out of them. — ¾-10 01:21, 4 November 2011 (UTC)
