BIGmouthinDC travels to Ohio to help build a Dennis Erskine designed space - Page 7

Building the Riser

The Erskine design of the riser involves a perimeter of 2x10s, cross members of 8x10's. The 8x10 space is insulated and an air gap is left at the bottom. a corner slot vent is cut turning the riser into an absorber. The technical details and determining the volume and tuning appropriate for your room are His intellectual property and you should engage him for help if you are interested.




"...an air gap is left at the bottom (of the riser)...."
How do you prevent the insulation from slipping down over time?
post #182 of 363
Good question! I'll answer it with a cryptic response...per usual. Is the insulation causing the resonances or the cavity formed from the joists that are causing it? I guess the real question is, does it matter if the insualtion is touching the floor or not?

DIY, In this case the insulation flange was stapled to the joists.
Shawn, just following the plans from your company.

My longest 2x10 span is 129" on a 2x12 perimeter. Should I use joist hangers?

IMHO not unless you are planning on having 20 people dancing on the riser. I didn't use them.

Did you secure the riser to the floor?

I wont be able to get the framing nails into the 2x10 (decking) studs from outside the perimeter framing on the back wall (the way I would have liked). My option then is to toe-nail them in, but never having done this before, not sure if they will hold the weight.

What's the purpose of putting Green Glue between the layers of decking in the riser and stage? Roofing felt?

I've built risers/stages with double layers with roofing felt, and Per DE's instructions done triple layers with GG. After thumping around with my size twelve dance shoes I actually prefer the later and that will be the way I would do my next personal theater. It was more rigid and quieter.

Big - I wanted to ask you about this construction method. I have seen Dennis' proscenium plans where two layers of 3/4" sandwich a layer of 1/2" with Green Glue in-between. This makes sense to me for trying to prevent sound vibration from transmitting into the floor and creating flanking noises in other rooms.

But for the riser, I don't really see how green glue and/or felt would come into play. Isn't it best just to glue (construction adhesive) and screw two layers of 3/4" ply with nothing in between for the strongest connection? What exactly does the felt do? Or what is the benefit of using Green Glue in the riser? Thanks in advance for the input!

The roofing felt is inexpensive, and it prevents wood to wood squeaks.

There is going to be bar seating at the back of the riser so some wiring and a conduit were required



Fotto stopped in for a day and lent a hand insulating, connecting the wiring and putting on the decking. A big THANK YOU.

What kind of cabling did you put in? Anything specific for controlling the Components via a wire (CAT5)?

I like the look of the stage!

They are at HD too. You need to cut off the metal parts that get in the way. Tin snips.

I think that I will get the standard size from HD (21 cu. in.) and not the refrigerator sized version from Lowes (21 cu. ft.)

Thanks

Those look pretty handy. if you need to move your fridge, just turn a screw.

Dinner time, I'm at the Somerset PA, service plaza. I stopped at the outlet mall in Hagerstown and picked up a refurbished Rigid job site radio for $80 at Tools Direct, normally $149. Now I'm on the hunt for frozen yogurt. may have to settle for an ice cream bar.

Here we go again! Went to a football game once at Akron vs VaTech. Isn't the stadium called "The Rubber Bowl"?
post #206 of 363
Hearing about BIG's road trips makes me want to see if he is interested in driving a couple more hours to the other side of Detroit.

Have fun guys!

Yep, The Rubber Bowl, although U of A has a brand new stadium they play at now (on campus). Not much going on at the old Bowl, except for the Soap Box Derby (which is right next to it).
