How do I?? / Re: lapping plate?

Lapping plate needs to be as flat as you want your  finished item to be. Google the 'three plate' method of lapping dead flat items such as surface plates. With only two the danger is of producing two identically dished items

How do I?? / lapping plate?
« Last post by shipto on Today at 05:48:08 PM »
I was watching a few youtube videos last night and saw one where a guy cut up a lump of cast iron and put some saw cuts in it for use as a lapping plate and thought surely for the price they charge for them there must be something... well more.
So while at work today I looked through my private stash of handy bits of metal and found a lump from a fire proof motor which had some holes I would perfer not to be there and thought I would give it a go and I have to say it seems to work well.
So this is more a am I missing something obvious here? below are pics of the plate which I would have liked to be bigger but its what I had and one of the lapping I did with it including some red marked areas where it wasnt doing anything.
Just want to make sure I am not making my mill head slide unusable really.

Might be jumping the gun but my lovely wife brought me the collet set for it.
I actually want the one with a 80mm chuck but they had sold out of those so got me the 100mm for the same price.

Got a cupboard full of machinable wax Ade  :ddb:

You might very well think that, I couldn't possibly comment!  :palm:

Actually, you'd be surprised how thin you can go and have it hold together; but yes, one overtightened bolt and before you know it you've got a pile of bits all over the floor....
