Advice -
1 : Definitely try the cut on an offcut first. Several times on different pices if possible until you are satisfied with having that join on YOUR WORKTOPS.
2 : Buy a NEW and good quality (Preferably TCT) Router Cutter.
3 : Make sure that the Router is at least 1900W.
4 ...
We only recommend using Danish Oil - It's an amalgamation of all the best finishing oils out there to create a superior product.
Don't by tempted by Linseed Oil or similar.
Hope this helps,
