Thread: Another project..

...I don't know where this will land, I don't expect to make a shaver sinceI don't have the skill. But a few threads here got me interested in the technique so I wanted to "hack away".

So far I think my el-cheapo-grinder will need some sort of attention, it does 2950rpm and my general feeling is that I don't have any control over the grinding...

I know it's presumptuous to put my bastard alongside a W&B, but I used that as a template...

Did some more grinding! This is a time consuming process!

I think I need to get hold of a wetgrinder now..

Did you soften up the steel first?

This IS interesting...

Yep, I annealed it in the woodburner overnight. Worked perfect.

Good on you for having a go ! Looks like it's getting there.

I think most guys use belts but I've used a wet grinder on a badly pitted resto job. Much less aggressive than something at 2850 rpm, a lot more control and no heat damage.

When I started grinding razors my friends grinder ran at 1750 rpm and drove a 10" drive wheel. That computes to

10" x 3.146 (Pi) = 31.46 inches circumference of the drive wheel

31.46 x 1750 rpm = 55055 inches per minute

55055" / 12 " = 4587 surface feet per minute!

This was far to fast to do any hollow grinding.

So, now I have a different grinder that runs at 1750 rpm and drives a 4" drive wheel.

4 x 3.146 = 12.58" circumference

12.58 x 1750 rpm = 22022 inches per minute

22022" / 12" = 1835 surface feet per minute

This speed allows me to grind the hollows much better but I will be slowing it down even further as I get closer to the desired thickness.

Hope this helps,
