Hi Kurt, Unfortunately, I think you may have misinterpreted what 'on the fly projection' and 'set layer CRS' are for. Your layer's CRS should be set to whatever the coordinates are actually measured in, and if your layers are indeed in lat/long (probably WGS84), then this should stay that way. If you change the project CRS to Irish National Grid (are you sure you want IRENET95/Irish Transverse Mercator? When I work with Irish data I usually use TM75 /Irish Grid [EPSG code: 29903]), then turn on 'on the fly projection', things should just line up (assuming you have the layer CRSs defined correctly). If you're concerned about it, you can also right click on a layer and select save as... to export to a new projection (but again, this assumes you have the initial CRS correctly defined. Do the layers that you are using have .prj files associated with them, if yes, then QGIS *should* automatically pick up the correct CRS, so no need to 'set layer CRS' at all.
