Mitre saw station -how do you position the saw?

[owsnap]

Hi guys, building a mitre saw station now(making 2 different tables at first and than fixating them together at middle and dropping also the mitre saw itself in the middle , can't post a picture but it's the same concept everyone is building.



I finished making it and made it so the mitresaw table itself is level with the 2 tables on each side, but when I tested it out it was more or less fine with very very straight timber, but as soon as the timber was a bit off it was lifting up from the mitre saw itself and you couldn't cut straight 90degrees every time, So I adjusted it and now the saw is 1.5mm higher than the both tables on each side and when you place a piece of timber on the saw it doesn't touches neither of the 2 tables and floats in air but it seems to work fine and now I can cut everything perfectly even if the timber is not perfectly straight.

but was just wondering what's the norm?

You make the whole thing level (saw and two sides). If the timber your cutting isn't level, you hold it flat close to the cut line.

At the end of the day, if the cut isn't a perfect 90 degrees because the board is warped, you've got bigger issues!

That's the delightful, individual qualities of timber

It is often a problem with mitre saw set ups and router tables.

You really need the table set up both level and parallel. Having the saw high will cause its own problems; when doing a trimming cut on a board end, you wont be able to get the board flat if the saw is high. Having said that, a fraction high you may find helps to keep the workpiece snug on the table at the blade, not as much as 2mm though!

If you are cutting in the centre of a bowed board and cant get it sitting flat, you could do a cut slightly over length, which will relieve the bow, then trim to final length.

have you checked the mitre saw table is flat and that you extension tables are perfectly parallel?
