Hi Dgreig, and a warm welcome to the forum. It's always nice to have another Scott Bonnar model 45 owner on board.

My advice would be to contact your local Bowling Club and speak to the greenskeeper and ask the name of the engineer/machinist who looks after their reels and bedknives. They are usually a friendly bunch of guys and will help you.

Your local mower shop can arrange to get it done, but they usually like to do the remove and replace themselves and charge you for that service....plus they have to send your reel to the engineer anyway. It is much better to remove them both yourself.
