My Build 3.0 - Maybe the final one???

[lpott6]

Been away for the holiday.
Thanks for the info Gene. If the stars line up, I will start construction in about 2 weeks. I will start a thread and post pics of the build.

Yes, I basically built an upside down U. The two side poles are bolted to the floor and ceiling. I used these

4)Screen direct from mfg. (Ordered with all guys on this forum), tied with bungee cords and tarp clips. I have emt frame bolted to ceiling/floor. Behind the screen are thick moving blankets and a canvas tarp. I get zero bounce. You will notice that there is 1.5 feet trough between screen and putting surface. All balls hit screen and collect in this area.

gene438 - Thanks for all of the great information! Can you elaborate a little bit about how and why the EMT was bolted to the ceiling and floor? Does the EMT effectively touch the ceiling so you are just using regular pipe straps, did you use conduit hangers, or something else? I am building a 16:9 EMT enclosure that is about 14’ wide, but it is only 13” deep. I am worried that it will be able to tip forward if I don’t secure it to the ceiling or the wall behind it and am trying to find the best option. Thanks!

I spaced mine out about 18 inches

Thanks....first, I way overbuilt mine with the 2 x 4’s but I wanted mine solid .... I did not put anything underneath... I layed the boards wide side down which gave me the right height. I stuffed around the boards with regular insulation. Then I nailed down the 3/4 plywood and sealed the seams and other rough spots with caulk...I did not want any lines or bumps coming through....The turf I bought had a 1/8 foam padding which turned out to be perfect.... if yours does not, you might consider carpet padding ......

Hi Gene, Love your build and I am going to emulate it in mine. Can you elaborate on the 2 x 4 spacing for your sub-floor? How far apart are they? I plan insulate it and use a tongue and groove sub-floor for the platform. Thanks for sharing.

[gene438]

I used standard can lights...you want to make sure when you buy the bulbs, that you are buying "spot" and not the "flood" bulbs.

Great build! How far apart did you space the 2 x 4s laid wide?

Great build and thanks for the detail. I am working on my build (affectionally called build 1.0) because I can tell this is a tinkering process that will likely take some time before everything is right. However, I am stuck on lighting and looking for some help. My projector setup doesn't like much light or it washes out pretty quick. I think I need a brighter projector. However, I also need a better light for the hitting area. I bought a battery powered motion light that works good. Good lighting and puts a nice circle down about 5' in diameter on the hitting area. My ceilings are 8'7" tall. Yes I can swing driver at 5'10" but it is tight. The light even has a hand held remote. However it takes two D batteries and eventually want to finish out the room. It looks like you have can lighting but the beam seems concentrated on the hitting area mostly except for the projector shadow. I talked to Par2Pro and local lighting shops but to no avail. The closest I got was a $300 flag pole light but that didn't make sense. I am not sure how a flag pole light would look in a finished space. It seems your light puts out around a 5 foot circle from 10 feet or so. Can you tell me what lights you are using so I can look into this more. Keep up the great work and hit em straight!

[gene438]

Acutally, I put in 5 holes....the 3 you mentioned and there are 2 more at the opposite corners of the room. I think my longest putt can be like 28 feet. Yes, I do use the middle cup as my aiming cup when playing in sim. For me, I know that if I hit to my middle cup that is 10 ft. so that is my baseline for all putting. I would not change my placement. The only issue you will have is that if your overall height is 2 3/4 to 3 inches then you will have to cut your cups. I searched forever and could not find any cups that were not 4 inches or more deep. So be prepared to cut them which is really no big deal. The only other critical point is cutting your turf to put cups in.....no easy way, just use xacto knife and a lot of patience.

Perfect! Question on hole placement - I noticed you'd placed 2 holes in the corners and one directly in line w/the launch monitor line. Do you use the middle one much with the sim? Also anything you'd do differently on overall hole placement now that you've spent time with setup?

Hey gene, great setup! I've been wanting to add a putting floor just like this - recessed putting cups and getting my fiberbuilt mat flush w/the green. Question on the wooden platform, did you put in underlayment cushioning between the garage floor and the 2x4's or it just wasn't needed? Also what did you use for insulation? The kids and I use the room for golf, movies and exercise and so when we run around on the platform we dont want it to sound like drums either. Thanks so much for the details on how you did this! -Steve

Projectors can have different lenses that can be purchased to allow for a throw distance change. If that's not available you may need a different projector.

Sorry anyways I meant to ask Gene, he's mentioned in the past what his projector is and how many lumens and where exactly that is placed that doesn't get hit by the ball, but let me ask again

[Detroit Bill]

Gene, I am working on a projector setup and I am a bit confused. First if you could provide the exact model of the projector it would help me. But you are using a short throw projector. When I look at that if I am 10 feet from the screen the projector is calling for around 6 feet from the screen to get the right screen size. it would be in front of me. I am looking at projectors without zoom perhaps that is the problem?

[Solstice72]

Thanks for the input guys. Money is down and Sim is going to be installed shortly. It'll be thru Par2Pro, refurb GC2, 15x 9. 4'' screen (16:9), throw probably at 15 ft and with 6500 lumens. About 22 feet wide of turf. Going ALL IN.

Any of you guys, Buckminster maybe, are you using a separate movie screen for movies?
