First, a big thank you to all that have viewed my videos showing my grinding rests being used. This I can see by the large numbers on my website and YouTube stats.

I have now come to the final two, “Four Facet Drill Sharpening” and “Wheel Dressing”. Links here. **LINK** .

My next videos will be in a series which I call “Made in an Afternoon” and consists of small projects on my website . Typical example here. **LINK**

However, this time of year is a very busy period in the garden for me, added to which, the local Salvation Army, of which I am a member, have asked me, due to my cabinet making interests, to make some simple items for their building refurbishment program.

Because of this, I will not be issuing any more videos for a few months.

Thank you Harold! You have answered my question regarding four facet drill sharpening that seemed to fall on deaf ears in this recent post. http://www.model-engineer.co.uk/forums/postings.asp?th=125481

I then remembered that it was in your book Workshop Practice Series 38, which I have read and is on my shelf! Dooh, memory….

Your video is very helpful in showing the grinder use. I notice now that you have some useful drawings on your website regarding the finished drill angles that do not appear in the older book. I give the link here in case others wish to find it http://www.homews.co.uk/page360.html see sk.7 to 9.

Perhaps that's because you tacked the question onto the end of another post that had pretty much run it's course. If you have a specific question it's better to start a new thread.

P.S. I have made H.H.'s grinding rest and four facet jig and it works very well.

Norm. I am pleased that you eventually found the information you were looking for regarding the four facet method of drill sharpening, and thanks for pointing others to the sketches on my website. I do not know why the sketches are missing in my book, but probably, I was still learning myself at the time when I wrote the book. Eventually, I did an article for MEW (issue141) which showed the sketches and with much more detail of the process. This, then used as a basis for what you see on my website.

Russell Thanks for your comments regarding my grinding rests and four facet jig.

Harold
