Grinding Reels

Yesterday was spent grinding reels to get them ready for the season. The machines that we have at The Nursery are a Foley 388 relief grinder and a Bernhard Express Dual 3000 spin grinder. We do not have a bed knife grinder, so in the winter, we put new knives on the reels. They usually last the whole season, aside from the greens reels, which normally get one regrind, and a new bed knife mid season.

Mid season I keep reels cutting paper without contact by using a Bernhard Rapid Facer 1000, and then backlapping. The rapid facer puts a nice edge on the front face of the bed knife, which does the cutting. Backlapping after then matches the reel to the bed knife. I use 120 grit for greens reels, and 80 grit for tee and fairway reels.

There is a lot of talk regarding backlapping and how grinding is better. I totally agree with that statement. But we do backlap reels a lot. Why? There is no mechanic, and a small crew here, so I am part of the crew to get things done. For our clientele and the standards at this course, backlapping and the rapid facer work wonders. If done properly, backlapping should not cone your reels.

In the winter months when I have time, I will measure all the reels' diameter with a Pi Tape. I put all the reels on the Foley 388 grinder and remove any cone that may be present. If there is no coning present, I still put a relief angle on all the reels regardless. I believe in using relief and not just spin grinding. I have noticed a huge difference in cut by using the relief, and backlapping also works a lot better with the relief angle.

Once the reels are done on the Foley, I then put it on the Bernhard Express Dual 3000. This grinder puts on a flat grind to the reels and it also confirms that all the blades are the same length, ensuring a great cut. It is very easy to use once you get the hang of it.

Once the reels are finished on both grinders, here is the finished product. A flat grind with a  relief grind. It is the best combo in my opinion. It is how the OEM ships their new barrels out.
