Hey hesh, being ash it will be pretty thirsty and soak it up a bit and being different pieces of timber you wont get a perfectly even colour, mine was a little bit similar but on basewood 1 stain and 2 intensifier coats Click image for larger version.  Name: 20170715_105216.jpg  Views: 227  Size: 162.8 KB  ID: 24939Click image for larger version.  Name: 20170715_155218.jpg  Views: 215  Size: 120.4 KB  ID: 24940Click image for larger version.  Name: 20170716_105108.jpg  Views: 226  Size: 105.3 KB  ID: 24941Click image for larger version.  Name: 20170820_104000.jpg  Views: 238  Size: 94.3 KB  ID: 24942 you might need one more stain coat as the first one has now sealed the tinber and it wont soak in as much
