Hi Tim,
I too purchased a Vertex HV4 several years ago and have been very happy with the accuracy and quality. It was quite a bit more than some "no-name" types on offer but I think it has proved a case of the quality remaining after the price is forgotten.
I had the same problem in mounting (both positions) and I made some custom mounting blocks to use the "pockets" cast into the table body from scrap aluminium as a little mill project .
I started with scraps of 1" square aluminium bar and cut two lengths to the width of the mill table. I then milled a rebate in each the height and width of the pocket so the bottom of the tongue formed was sightly lower than the base of the pocket on one and slightly tapered from low to high on the other (to form a Wedge arrangement to the pocket)
I then took two "T" nuts (also a mill project) and then drilled the blocks to take 8mm Allen cap screws rebated into the top. When the blocks are fitted either side of the table by mounting the wedge block and tightening it down and then sliding the table into it (the cap screws are not accessible on one block with the table in place) the other is then slid into position and tightened down with the cap screw to clamp the table in position. The blocks were given a brush finish using a medium carborundum/rubber block
You can mount the blocks wherever you like but they can be fitted at the very end of the T slots to give the maximum work envelope

Hi folks, first post. I purchased a Vertex HV4 rotary table and am very happy with the quality of it. I didn't think however I'd have such a head scratching time figuring out how to mount it vertically, while allowing for as much x-axis as physically possible. Basically I am seeking suggestions for how I can mount this as far left on the table as possible, as I have some longish pieces of work to hold. I mounted it with step clamping blocks but this took up a few inches of left-of-the-RT in x-axis real estate and puts the tip of the 3jaw chuck past the centre point of the table! I tried sneaking some low profile step claps underneath the chuck side to hold it but the weight and centre of gravity really wants something forcing the unit down from the top or from the rear (left hand side) hopefully this makes sense without photos.
There doesnt really seem to be anything to clamp on, on the table. I am happy to post some photos but its a fairly common RT so I figure someone must have one and figured this out.
Many thanks in advance,
Tim
