The Father / Son team (still somewhat nubes w/ this TRT 4th/5th stuff) are actually getting the TRT-210 squared in for a first test learner part. (old Haas... 98' VF/4) and we did spend 2 hours getting the entire table level w/ a 12" .0005 level. it's pretty darn close overall X and Y.

Anyone have tips what they to do mount this TRT monster firmly and get it squared in?

He's putting the 4 Toe fasteners on the outter t-slot runs. (under the 210 large base A unit). Installing inner and outer toe mounts like the diagrams on the HRT manuals.

...But, I think he needs to do some gross alignment w/ the B plate turned to 90' (full face to you). and brass tap the base till the face slides at 0' along X travel. Then he can go back to putting B-face flat and getting that level by tightening the toe/base mounts on the A unit appropriately from each side.

He's been trying to sweep his dial face around and struggling w/ how you get this thing square and level by the hold downs?
We stuck it on the table, (there are t-Slot guides on the 210 A unit)- And tighened it down and it's no where near flat until he starts playing w/ the tension on the hold down setup? That seem right? He things it should just go on and be flat...

We did not find much on the manuals, you-tube vids, etc. Any help appreciated.

Having the indexer and table level gets you nothing. Having your machine aligned correctly is crucial.

Your son is correct, the indexer should- must set flat. If it isn't, something is wrong. Having to use the hold down bolts to a make it flat is only going to cause problems.

You need to have the indexer perpendicular/parallel to the X/Y/Z axis of the spindle and table motion. This gets back to why the indexer needs to set flat.

Since the indexer is being mounted to the table, whatever issues that the table has in X/Y motion are going to automatically affect the indexer alignment. The only way to determine the X/Y errors is from the spindle as that is what everything needs to be in relation to.

Setting up the indexer is more like aligning a lathe. Best to use a precision round bar in the indexer after you have it rotating in the indexer with as close to zero runout as possible.

After you have the indexer setting flat, you want to put an indicator in the machine spindle and align the indexer for X axis motion on the side of the test bar.

There is not much you can do for the top of the bar reading since it is a result of any table X motion errors.

If you want to do 4 and or 5 axis work with an indexer, you must have any and all table motion issues resolved as they will simply multiply into errors on A and B axis.

It is also important to understand that the indexer rotation is relative to the starting point. Your indexer does have a home or zero deg position but all rotation is measured relative to the zero position.
 
sounds like you've got a burr or some shit underneath the table. When you bolt it down and tighten all 6 clamps, the table should be dead parallel indicating it side to side. (X) If not, there is something wrong.
 
Thanks all- He's in business. He hoisted it up, went to stoning, prepping , and laid it back down gently and evenly. Indicated .0002 He's a very happy kid for now. Yeah... Larry was spot on. we had a high spot or two, a big nick, and just general beat up table spots.

Appreciate the help as always!
