Drill grinding on a budget
SAM_0585.jpgSAM_0584.jpgHello from the old goat.
Many years ago after suffering a few cheap plastic attachments I bought this. My drills improved in accuracy and flat bottom or zero angle drills became my norm.
A good project for the wet day.

It would really help declutter the forums and save the mods work if posts on the same topic especially by the same member were posted into the same thread. Even better would be to search for a preexisting thread on the same topic and post into that.

Great idea Bob,
Drill sharpening is an oft visited topic.
If there are not too many who oppose the idea, I am quite willing to start a thread myself and move any "strays" into that thread when and where they come up.
Same for other general "how to" type topics as they come up.
There ya go boys, what do you say to that one ?

Drill grinding
Hello Grahame.
Yes drill grinding is a topic often commented on. Tool and cutter grinding is a general topic not well understood. Also good information is scattered and hard to find. Then it must be verified. I am currently trying to locate a copy of a book, The Art of Tool and Cutter grinding by J.P Narang. No luck so far but I have seen it described as one of the best on the subject.
Any chance of a sub forum for all tool grinding and toolroom work? This makes it fairly broad in scope but still specific. There is a Facebook group for tool and cutter grinders. It seems to be for the CNC guys and other enquiries don't rate an answer. So much can be done in the small shop with a good 6" bench grinder. Harrold Hall's book is a good start.
What do you think.

Problem with this is that the search function only links to the first page/post of a thread containing the search term, not the actual post containg it. This means you need to trawl through dozens if not hundreds of posts, often irrelevant to the topic at hand, in order to find the gems of info you're looking for, if they even exist.
Individual threads mean you can assess the validity of the information, idea or suggestion by reading, at worst, the first few posts of the thread which is where the search engine sends you. Some of the threads on here go north of fifty pages and spend more time off topic than on. These threads, which can contain small amounts of fantastic and useable information are now pretty much worthless because it is too difficult to find.
Cheers,
Greg.

FWIW I always use Google for searches, and never use the forum search. To restrict the results to just this forum use "site:metalworkforums.com" in your search.
The Google result typically takes you to the actual post containing the search phase.

Hello Grahame, having just aquired a fairly complete T &C Grinder I for one would benefit from a T&C forum. which would hopefully cover sharpening techniques for a range of metalworking cutters and hopefully the jigs, commercial and DIY used to accomplish the tasks. Been nearly 50 years since I did the trade and my memory needs a refresher / reboot with this machine. Thanks

Drill grinding on a budget
I’m working up some plans based on this video:
https://youtu.be/9wxnwwOzTh0
The plan is to build the jig against my bench grinder with a diamond wheel as the grinding medium.
Some parts are really cheap to buy ready made. For example I can buy an ER16 collet chuck (with straight shank) for $15, I can’t even buy a 22x1.5mm die for less than that.
Not sure it will work but I’m pretty confident I have it all planned out. I reckon around $80-$100 less the collets and grinder.
I’ve usually ground drills by hand but never really mastered the art and I cannot hand grind them for small ones. The hope is that this offers the precision required to properly grind 2-4 facet drills but to also do it with accuracy for 2mm drills too.

That's usually what I do as well.
It is also possible to restrict the google search to a specific forum by appending the forum number to site:metalworkforums.com
eg metal work projects is forum 303 so the search term is "site:metalworkforums.com/f303"
The forum number can be seen by going to the forum of interest and clicking on the URL window
There is also a search function from within a thread that is often pretty useful.

It works extremely well. There is a project write up on here somewhere.

It's a nice thought guys, but if you look at the sort of thing being posted at the moment, I suspect that a dedicated grinding (or even toolroom) section would not be a well used sub-forum. While we have a number of discussions going on on all sorts of topics, very few members seem to be posting accounts of what they are doing.
