One thing you could do...but may take time is look up the patent, "DreamGreen U.S. Patent No. 4,978,127". You might be able to order a copy of the patent application that has the plans and see their design.

Great Idea! I bought the patent for 3$ online. I will try to post it but it is a big file.

Realize this would be very involved compared to building a frame and shimming/wedging things underneath to create break. It's feasible to use small linear actuators (small electronic device that slides a bar in/out - typically used for car stereo installs/lowriders to move panels/amps/etc). They're typically strong enough to support your weight should you walk on them, relatively simple to wire/control, and would probably do the trick. You'd just need to build the top of the platform out of smaller square sections, and not screw them down. Sort of like a tongue and groove floor, you're just looking for a "floating" platform. When triggered, the actuator would lift one of the 4way corners, creating break. It'd be a bit of a pita to get them level, should you want a straight uphill putt, but from the sounds of things, you're looking for a lot of "randoms". You'd need to use some form of padding underneath to smooth the edges, and fabricate brackets to lock the plywood sections to the actuator, so they can't slip. A lot of potential pitfalls, but hey, I tried. ;) You could potentially mimic their methods, as well. The cheap scissor jacks for spare tires would do the trick, and absolutely support the weight. You'd just need to attach a bar extension to the eye ring, so you could adjust them from the side of the platform. In either case, you'd need to have excess fabric at the sides to prevent stretching. *shrugs*

In short, there's a reason the adjustable greens cost so much. ;) I'm curious as to how close I am to the patented methods though. :D

I built a putting green in my basement for less than $75. It wasn,t to hard. It's a little bit cheap but it does the job. Also, the green is quite big, a 12x8 rectangle.
Pros: Bigger green for longer putts, cheaper than others Cons: No break
Supplies: 7-2x4x8'
2-2x4x12'
3-3/4x4x8 plywood
96-square feet of indoor outdoor grass carpet 30cents a square foot. compare to $3 or more.
100-2 3/4" drywall nails
1-17" long, 4.25" diameter pvc pipe
staples for carpet

Tools: Hammer, 4.5" hole cutter, staple gun

Instructions:
1. Gather all supplies
2. Line up the 2x4s in a 12x8 formation, studs 24" apart.
3. Nail the frame together(screws are optional)
4. Nail the plywood to the studs
5. Staple the carpet to the plywood(glue is optional)
6. Use the hole cutter to make 4 holes
7. Cut the pvc pipe in fourths
8. Put the pvc pipe in the holes

There's your cheap winter putting green!

did you consider making the holes much smaller for practicing like a practice dart board(doubles and triples only half as wide).

[dawg28]

no i did not, nvm.
u could just modify it when u build it by cutting the holes only 3 inches and getting a smaller pvc pipe.

does anybody know where i can get really cheap putting turf? I'm talking less than $1 a square foot.
