You'll wonder how you ever cut anything before you got everything zeroed in. Nice job!!

Darren,

Sorry I couldn't help earlier, but Stew sorted you out anyway.

I hope you realise that this topic is about getting rid of the antiquated system you have just made.

For your pennance, you have now got to use your new found accuracy to make one of my tramming tools.

It's nice being square, ain't it?

Well done.

Have faith, I will get there. One small step at a time. I just needed something that would do the job for now AND one that could double up to sort my vice out as well.

OK, now that the mill is much better set up it's time to sort out the vice.

Mine came with these locating tags. Not much use as they are as you can see. When the mounting bolts are located they pull the vice too far forward to use them.



This turned out to be a simple fix





That done it was now time to true up the vice  jaws to the bed. This gauge reads to 10ths of a thou, I ended up chasing two tenths and then realised that if I simply placed my hand on the vice the gauge would move by two tenths. Wow, two tenths aint much is it ..!!
So I left it at that.



Back to the other tool that I made earlier tonight to set the jaws horizontal to the quill. Now you can see why I made two mounts for the dial gauge. With my vice being handy to set to any angle, it's just as nice to be able to put it back again quickly and accurately.

The vice overall is now easy to set perfectly true, just five min or so and it was all done.

Darren,

If I could make a suggestion to get a better result for you.

On you first measurement, using the DTI. Instead of clocking along the pitted and worn inside vice jaws, put a parallel in there, and clock against that. You will then get a more accurate 'mean' reading. It would also help if you used your diamond plate to gently knock off any high spots on the jaw faces.

For the second one. The top of the jaws might not be parallel to where your job is sitting down onto. Pop a parallel down onto the inside of the jaw base, and clock off the top of the parallel.

I now see you are starting to come along in leaps and bounds, striving for accuracy. Whereas before it was wack it in, and that will do, now you are talking in tenths of a thou.

Keep it up.

John
