Hi
dramapig, and a warm welcome to the forum. It's always great to welcome another Scott Bonnar owner on board, as we all like to learn new things and tinker here!

The best way to find a good engineer/machinist to sharpen your reel and bedknife, is to contact your nearest Lawn Bowling club, speak to the greenskeeper and find out who sharpens their reels....Greenskeepers are usually a friendly bunch who will help you.

Looking forward to seeing the pics of your Scotty, once again....
