I have some carpet in my house that I am thinking would rate pretty good on a stimpmeter and was curious what I should do to measure it so I know what it rates against normal muni greens in the area as well as higher end courses around me.   yahoo

The Stimpmeter is an extruded aluminum bar, 36 inches long, with a V-shaped groove extending along its entire length. It has a precisely milled ball-release notch 30" from the tapered end (the end that rests on the ground). The underside of the tapered end is milled away to reduce bounce as a rolling ball makes contact with the green.

 
The V-shaped groove has an included angle of 145 degrees, thereby supporting a golf ball at two points " apart. A ball rolling down the groove has a slight overspin, which is thoroughly consistent and has no deleterious effect on the ensuing measurments.

The ball-release notch is designed so that a ball will always be released and start to roll when the Stimpmeter is raised to an angle of approximately 20 degrees. This feature ensures that the velocity of the ball will always be the same when it reaches the tapered end.

It is not easy making a stimpmeter, you need a CNC machine. You are better off buying one. The PGA charges a 150 bucks for one. This is definately cheaper. http://www.rittenhouse.ca/asp/Product.asp?PG=1909

Well, thanks for the info, but I don't need to know that badly! I was thinking if I could take some simple channel from Home Depot and cut it with my hacksaw to get the right length and then hold it at the right height....

I am cheap, I know, but for figuring out the speed of my carpet...   russian

a carpet tends to be a lot faster than an actual green .... unless you still have that 70's shag in your home

Nah, my carpet is a really thick carpet, just a very even thickness. Very soft when walking on it, kinda like having a built-in pad. The installer that put it in was sweating really bad when installing it because of how thick and heavy it was and he had all the windows open on a cold day. He wasn't happy that he was doing the install on his own that day.

I think you could make one that is close enough for your purposes. Take a piece of wood with the channel in it, make a mark at 30" from one end, and put a couple of legs on it so that it's at a 20o angle. Then set a ball at the mark, and roll it down. Close enough...

Dave, I am sure I will end up doing something like that. Home Depot (Lowes, ACE Hardware, OSH) offers channel iron and some even have aluminum pieces of angle's that you can buy, I would probably do that. Or, if I want to keep the 145 degree angle, I could also make my own with wood, like you say.
