newby trying to flat gring

joe9knives · Oct 17, 2006

I am having trouble getting bevels flat. I use my 4x36 sander and 6 inch disk. I also have tried files. I would also be interested in hollow grinds, but I imagine that would require a special grinder. I know my sander isn't optimal, but I thought you experienced guys might know some tricks. thanks in advance. Joe

First off - welcome to the forum.

If you rent this video http://smartflix.com/index.php?main_page=product_info&products_id=1041 it will show you how to do a flat grind with your 4X6. They also have videos for rent on hollow grinding.

thanks Jim. I'll have to check that out.

Also you might want to contact Darren Ellis and pick up a piece of Glass platen material. I bought a 2x6 " piece and placed it on one side of my 4x36 'platen'. Now I can put in my plunge lines and my bevels are flat(er, I still am not very good at this.). It prevents you from using the whole table, but Iw seems to be much better to me.

To solve that problem just purchase or make a replacement table for your grinder and grind away the front of the table next to the glass platen. This is what I did with one of mine.

The video "All About Grinding" is also available from Darren Ellis's web site for $30. The rental place "Smartflix" looks like it has a lot of interesting stuff to look at, but at $9.99 per rental I thought I would just pay the extra and own the video. I too can use all the information I can get on the grinding subject.

I know grinding with a 4x36 all too well, what I did was take a piece of precision ground plate 1/4x2x6 and bolted it to the grinders existing platen, as close to center as I could get it...wish I had of known about pyroceram then.
I used to take my 4x36 belts, flip them inside-out and cut them into 2" belts (<--pain in the butt)
the down sides were belts wearing out way too fast, and the edges of the old platen getting in the way... I was thinking of cutting away the side of the old platen as Jim mentioned, but never got around to trying it out.
