With the help of my buddy Todd, I have completed Harold Hall’sDeluxe Grinding Table as described in his books. I have also completed thelathe tool jig and round tool jig and will make the drill jigs when I returnfrom vacation.
If you have built this table, I would like to seepictures/descriptions of your set ups and how you use your table. I have notcompleted my setup yet. I purchased a new bench grinder and replaced the standardgrey wheels with a diamond cup for carbide and a white aluminum oxide straightcup for HSS. The guards over thestandard wheels need to be modified to cover the new cups, and my table needsto be mounted, so I have not used the table or grinder yet.
I am also interested in seeing any methods of mounting adiamond dressing tool on the table to dress the white wheel. Todd kindly gaveme a diamond dresser that is mounted on a Ĺ” dia. x 1 Ĺ” shank and I need todesign and build a jig for it.
I am not the greatest machinist in the world, and I startedthis table early in my experience level, so the fit and finish isn’t pretty.When I visit Todd the next time, I hope to have him grind the parts of thetable and my attempts at tool jigs, and when that’s done, I’ll post pictures.
In the mean time, I hope to see lots of pictures andtechniques posted here so myself and others can learn from them, so TIA!

I have completed Howard Hallís Deluxe Grinding Table as described in his books.

I believe that's "Harold" Hall, and if you visit his website http://www.homews.co.uk/page3.html
and put "grinding" into the site-specific Google search box there, you will find links to a number of his pages showing the grinding table and modifications to it, including plenty of photos of it in use.

I hope that helps!

I do that all the time, I know his name is Harold, but can't seem to type it right. I fixed the origional post. I even had an Uncle named Harold and try to associate them to get it right. Sux getting old... Maybe if I refer to HH as "Uncle Harold"...

Edit: Half right, I got the post title right!

When I get home and finish the grinder setup, and get the table mounted next to it, it'll make sense.

I realise that this thread has been dormant for quite a few months but my website statistics still show viewers coming to my website via it.

I have had a look at your pictures of the rest Chuck and its accessories, you certainly appear to have made a fine job of it. You were asking for more details for using it, and even if you now have it fully up and running I am sure that there are some who will find the following pages on its use, helpful.

Thank you so much for the additions to your website. I appreciate the work that goes into such endeavors. However, I must report to you that from the second page of the first link you posted, the last line of text is unreadable. The problem occurs on several pages and is the same viewed in IE or Firefox.

Sorry Chuck that you are having this problem, one which I have been aware of for some time. The solution should be to view the page at a larger, or smaller, zoom setting. As the text is hidden you may assume that useing the larger zoom setting should be the way to go but this is not always the case, so try going up and down, maybe even more than one step. On my PC the method is Ctrl + and Ctrl - and Ctrl 0 (Thats Zero) to reset to the norm.

The reason for the problem, typically, is that individual letters may not be able to expand by the percentage increase being applied to the page. For example, if a letter is seven pixels wide and the page is increased by 25% then for the letter to expand by the same amount it would become 8.75 pixels wide. Obviously not possible as one can only have full pixels.

The result of this is that the program will try to use 9 pixels The result of this is that the text may wrap differently, and in some cases produce another line of text, maybe even more than one. This happens on very many websites, even typically on the UK BBC website.

However, they were aware of the problem and allowed more white space at the bottom of each column for the extra lines of text which may result. When I became aware of this I made sure the last line of each paragraph ended up with just a few words in it and with a spare line at the bottom of the column in case a paragraph still added a line.

More recently I have been adding two or more spare lines on each column, but with over 600 pages it is quite a task but am working at it. In the meantime try viewing at different zoom levels.

I will make the changes to the link you are having problem with report back.
