I'm scraping the top parts of my HLV and thought I would share this. I removed the pivot ring from the compound slide base and stuck it on my plate. It rattled a bit on the ends so I stoned it for burrs and went again. Still rattled a bit so I stoned the top flat for burrs and inverted it on the plate then ran my DTI over the bottom flat surface. It was high (whist inverted) in a line right across the clamp bolt and low on the ends by 2 thou and a bit.
I scraped the base flat just roughly with the Biax and put it on the plate right way up. The ways are low in the middle and high at the ends, as is the top flat face. The compound base casting is totally banana'd. No wonder the clamp bolt was so stuck it sheared when I tried to remove it - the previous owner must have barred it up tight trying to take the rock out of the base.
Got a lot of scraping to true everything up. Good job it's not a taper gib or I'd by making a new one of those too.
