First of all ..... this is not my idea. Username danielplace, in my original post, told me about this type balancer...... and THANKS.

This was virtuatlly made for nothing by using scrap wood that I pack-rat away. My prop is 70 mm and the hole is threaded and NOT all the way through. My prop shaft is more than long enough to keep the shaft balanced across both razor blades. This will cheaply give me a balancer that will be more than enough since I am not in racing or competition.
Thanks again Dan,

you might want to check the balance of all that hardware before you start grinding on your prop.

When I started out I used a piece of 1/4" brass tube and would use the edge of a drinking glass or sauce pan (Careful using saucepan if your wife is around). It will get you pretty close. Cost about $1 for the tube.

Thing I dont like about the balancer with the razor edges is the razor edges - you know they are going to draw blood at some point in their lives in the shop.

Yes you have a good point best to hit up the kitchen for a solid plastic container and religiously store it in that up on a shelf somewhere or it will inevitably get you.

Thanks Daniel

I was going to add the split fuel line tubing over the blades for a second photo........ but did not. You are correct. It will draw blood![:-]

black talon, What do you mean by "all that hardware"? Remember....... I am new to boats. Do you mean the prop shaft? The boat is large and has a 17 inch prop shaft. I laid the prop shaft on the balancer and it consistantly went to the same spot, marked with a Sharpie. I realize the shaft, being so long, could be bent slightly. I used to straighten aluminum arrow shafts, (even by hand), when I was shooting target leagues, and this looks real true. I have a plate glass top on part of my bench and it rolled as true as my eyes could see. One blade on my 3 blade prop is heavy, and so far filing has not helped. I lined up this heavy blade with the "alleged light side" of my drive shaft, but did not see a difference in balance. (Figureing there would be a little change anyway. If I keep filing I will have a 2 1/2 blade prop. Kiddin' ..... but I am keeping an eye on comparison with the other blades. Remember ..... I am not into competition or racing, but I know I don't want to run with this balance as it is now.
Thanks ..... lownslo
