Thread: Herman surface plate tool

G'day Mark,
Sorry I can't help you with your new toy but I might be able to help with the enter key problem.
This drove me bananas for ages and apparently has something to do with the forum interworking with IE10.
The other day, completely by accident I stumbled on a fix:

Click on Settings at the top right of the forum page.
In the My Settings section on the left hand side of the page under My Account click General Settings
About 2/3 down under Miscellanious Options is a heading Message Editor Interface

By default Enhanced Interface - Full WYSIWYG Editing is selected
Change this to Standard Editor - Extra formatting controls
Scroll to the bottom of the page and click Save Changes

This fixed the problem for me so it might be worth a try.
Cheers,
Greg.

G'day Mark.

I have no idea what it is or does.

Do you want me to put a link or some pictures of it in the Metrology section at P.M.

I'm thinking some one like John Garner would know.

Regards Phil.

P.S Just out of curiosity, how much did the repeat-o-meter go for?

Hi Phil Feel free to put a link on PM as I really can't see what it can do. There is a cavity in the upper right of the box they may have held something important. Won't really know till it gets here and I read the instructions for the Tol-check instrument. The repeat-o-meter only made 255 US$. Heres a link http://www.ebay.com/itm/STARRETT-SUR...-/221564156242

Thats really cheap for the repeat O meter.

At least it comes with a set of instructions Mark, hopefully they will shed some light once you have it!

Interesting bit of gear, I can't see how it works either... I guess I'll keep an eye on PM top see what the answer is?

So some Xmas goodies finally arrived from Shipito AND I finally found my charging lead for my camera !!
Here are some pictures of the Herman stone surface plate tool. Lucky it also came with instructions.
As was previously surmised a dial indicator (no less sensitive than 0.00005 ) is placed on the end of the bar where the screw is. The heavy granite pad has 3 carbide feet with which it sits on the plate. The bar came be moved out so the dial indicator sits about 12 inches from the pad with some locking screws as well as an adjustment screw. Originally it came with its own 12"x18" super finished master plate and the tool was placed on the plate and with the adjustment screw the dial indicator was brought to zero. The tool was then moved to the plate to be tested and moved across the plate from corner to corner, or grid pattern or series of circles to ascertain the flatness and repeatability of the plate. Hope this makes sense.
Even without a setting plate it still makes a workable repeat-o-meter.
I am away with work till the new year but will try it out when I get home.

That will work perfectly with your 20 uinch Mahr Supramess.. If you just set up on a known portion of your surface plate, then the measurements will be relative to that.. As a repeat-o-meter it's always relative measurements.

Exactly what I was thinking Ray. Look forward to seeing how the various plates measure up.
