Andrew,

I won't disagree with your assessment of the picture quality - the grinding looks pretty good to me.

A horizontal surface grinder usually (always?) has the grinding wheels mounted on an arbour with facility for balancing.

The wheel being out of balance is probably the cause of the slight ripple.

Your table drive arrangement is very different to my Union (I'm not sure it's a Union but it may be a clone - there are no markings that I can find.)

One job on my 'to do' list is to make a surface grinder and I was going to use a timing belt drive for the traverse.

Good luck with your HPC enquiry.

Well I thought that it was time for an update on this saga.  I looked into the new gears and at what would work out at over £150 I decided to give it a miss.  I changed the wheel and finish improved to the point where if I took very fine final cuts the waviness was not perceivable.

Here is a picture of the finished machine:


I added a tenths indicator and fixings as well as bellows over the pillar and gave it a splash of paint:


I made a lathe tool bit holder, and endmill v block and a magnetic parallel as well as purchasing some commercial mag parallels (£5!)

Andrew Wildman:
all the attachments fit into the cubby below the machine (surface grinding stuff top shelf, tool grinding below)
