Thread: Maplin Microscope

Guys,

Is this the same as the Radioshack one recommended by so many?

Si.

No, it's not. Might be good however. I've attached a picture and a link of the Radio shack micro. take care - John

I have one very similar to the maplin one, it worked ok, but you can only get the blade in one way, and you have to remove the arms that hold the microscope slide in. Unfortunately i can't use mine any more becasue the bulb blew and i'm not sure where to source a replacement!

What's the best way to use the RS microscope- I get it focused, then move across the blade, then not focused- I'm sure it's user error. Sigh. Also if anyone is looking for it, here's the link...

We now return you to your normal thread, thank you for your patience.

Moving across the blade, the scope should stay in rough focus, unless the mechanism is so loose that even small movements can affect the focus. As you move across the blades edge, you should not be changing depth of vision (keep the clear plastic guard down on the blade face) only moving laterally.

As for what to look for, I look at two details;

1. Are there any lines running parallel to the blade edge? There should not be, and any lines in this direction probably mean you have a dual bevel on at least one part of the blade. If so, back to the 4k side of the Norton.
2. Are the striations perpendicular to the blade edge a consistent width? If not, some areas may have not be as flat to the stone and not receiving the finer grit cuts. If this is the case, check the flatness of your hone, how wide the smile is (too much and it is hard to maintain a consistent bevel across the entire face) and whether the tape on your spine (if you use it when honing) is flat without creases.

There are probably about 100 more things that the experts check as well, but those are the two that I understand and can correct for if I find them.

I specifically look to see that the edge is smooth. I don't worry about the striations too much myself.

Thanks guys. Do you lay the razor flat on a light background and move the scope, or put the blade in the grove between the black and white plastic?

Draxe, have a look at this thread. There's helpful info on using microscopes throughout, and the 13th post by JoshEarl gives a good technique for keeping a steady focus.

Perfect, just what I was looking for. Thanks!
