BTW. This message is now being sent with my all singing, all dancing, new desktop computer.

From a bare bones box, to being on the net, 1.5 hours.

Nice to see that you have the new computer up and running. Just remember that now you it can make can make bigger screwups faster.

Stew,

If it falls apart, just reassemble it with some some good stuff.

Don,

I said onto the net, not finished.
I have another couple of days getting it how I like, then I am going to try the new windows 7.
It is supposed to install directly over XP 64.

Since this is the last we'll hear from you for a (long) while, John, I just wanted to say how nice it's been knowing you.  Best of luck in your new career as a Micro$oft beta tester.

Ok I'm going to get on my high horse:- (high horse smilley)

When at the midlands show the other week I was on the look out for a green cupped wheel, but I was a bit p****d off that none of the suppliers seemed to sell them with the paper discs, these disc are relay important for two reasons it should tell you the type of wheel grit size bond hardness etc and the maximum safe speed of the wheel, and its important for safety reasons and the security of the wheel that are between the wheel and the clamp washers.

Her's a pic of the green wheel I bought and the card washers I've made for it along side a UK manufactured white wheel correctly supplied with washer with all the correct info on.




So the massage is USE PAPER WASHERS TO MOUNT GRINDING WHEELS

I'm off my horse now

Some of the wheels I want to use have a bore larger than my spindle, so I made some bushes for them along with some clamp washers:- its good practice to use washers that are the same diameter so you get even clamping on the wheel

Her's a pic of all the kit to fix a wheel, Spindle  I made an extension to the spindle with a male and female mouting so that mount a wheel further out) Washer, Paper washer, Wheel with bush, Paper  washer, Washer, Nut.



And this is my collection of wheels and quills.



The small wheels were kindly donated by another madmodder.

Cheers

Stew,

am getting quite jealous - even more so when we see some of the results of this. It's like you've got a whole new machine tool!

Hi Nick

I'm hoping to be able to do quite a bit of interesting work with the grinder, but we will have to see how it goes.

Thanks for taking an interest and posting comments.

Cheers

One thing a grinder really helps with is when you have that bit of material that you can never get a good finish on. It can turn a real crappy bit of turning into a work of art, and accurately dimensioned as well.

What people also don't realise, grinding can also be used on materials that you wouldn't be able to shape otherwise, rubber and glass to name a couple. One of the jobs I did entailed surface grinding a rubber block to an exact size and shape.

Stew,

was just thinking, is there any way you could mount the spindle on a verticle slide so you could grind small bits flat in the 4 jaw?

Nick

Nick

Thats going to be the next project I'll be posting, I'm planning on using a vertical slide of a lathe for this :- Your starting to see the posibilities from this bit of kit, I'm not shure if it will work but it will be fun trying 

Cheers

It's brilliant Stew.

bit  I am seriously thinking about trying to turn adapt my horizontal mill into a surface grinder to give it surface grinding capability. I think it was Darren that pointed out, it's already half way there. There is a pulley on the back of the existing spindle (not sure if that could be utilised directly though as the spindle is driven through the gear box which would only give maybe 1000rpm. There are dovetail slides on top of that so the grinding spindle could be mounted there. The table can be moved longitudinally by a lever ... will put that up in another post when I get round to it!
