Not the sharpest tool in the shed.

Okay, so some of you have been on the ice already while the rest of us are waiting optimistically for that any day now moment to come. Many new comers who have just acquired a barn find or new to you boat, may be faced with the fact that the runners may not be all that sharp under those layers of rust. If you have some simple wood working skills and a belt sander, you can bring those blades back to life. Obviously the jig is geared for plate runners. Insets should have a more qualified person and device for that race quality edge. With hours of practice and a good light box, I have done a reasonable job putting a sharp edge and rocker using this set up. The rig is simple using a piece of 4×4 squared off, and scrap plywood. A few bolts are used to allow adjustments to get the edges parallel and even in height. The distance between the edges should be wide enough to allow the sander to sit flat and level but not slide off. I used a couple different sanders and they all seem to work with this setup. Warning! You want to remove the bag so sparks won’t set any residual sawdust on fire. I use belts that have passed their useful life for wood. Different grits can be used depending on how much you need to grind. I find a used 120 grit gives a pretty good final edge. Honing would be the final step if you feel you need that mirror image for that little extra speed.

With practice you’ll feel the best way to move the sander over the edges. Start with going the full length of the runners in a smooth movement. After about 10 sweeps I will flip the runners side to side and work on the matching edge. I also have a damp rag to keep the edges cool. Don’t destroy the temper. Adjustments can be made for areas that may need a little more material removed. Checking on the light box will give an idea how well it’s going. If you don’t have a light box, I have used the table saw top with a light behind it.

This method has worked for years with me but I’m just a cruiser and the edges seem sharp enough for my sailing. I hope this helps for those just getting started and may not be around someone with a fine detail machine.

Stay sharp and catch you on the ice……soon.
