I am currently building a conductors’ rostrum for my wife’s high school. If you’re not familiar with what this is, think of it as a small table, 34”x34” and about 8-9” tall, and the band conductor stands on this while they’re conducting. I’m about 3/4 done with the base, which has spalted maple aprons and cherry legs.

The top will be a square of 3/4” plywood. I will be covering the top with grey carpet, the really short type that is commonly sold as trunk liner for your car. I plan to use contact cement to adhere it. I would like to trim out the top with cherry. The issue I’m pondering is, how to design this trim such that it will overlap the carpet (to hide and protect the the carpet edge), and be able to be stepped on without breaking.

My current thought is to cut a shallow rabbet, maybe 1/4”, around the top of the plywood. Then cut the trim as pictured below. Then, glue the trim in place, mitered at the corners. I don’t suspect there will be an issue gluing this narrow of a piece to the plywood, I’ve glued wider pieces of 1/8” thick walnut to plywood for a fake frame & panel look, and that’s going on 4 years without any issue. The top is going to be pocket-screwed to the base, so it will be replaceable if it needs replacing after the years. The only potential issue I see here is the thin part that overlaps the carpet being susceptible to cracking, I would like to keep it at 1/8” thick there. But, if I cut the trim accurately, I may be able to get it to sit tight to the top/carpet, which would provide support.

If anyone has any other ideas, please do share them.

Hmm, seems too complicated for what you are getting. You could get the same effect with hardwood edgebanding, attached with biscuits. Chamfer the edge, and miter he corners as in your example. Just skip the dados. I don’t like the idea of leaving such a thin lip on the edgebanding. It might be problematic to mill that odd shaped trim, because most of the stock supporting the workpiece will be removed during the router table or tablesaw operation.

I don’t think cutting it would be a problem, I would install a ZCI with a dado set, then cut out the inside of the blank (2x wide as trim), then flip it over and rip it in half to make two pieces.

I’d really like some way to protect the edges of the carpet. Contact cement is good, strong stuff, but eventually, it’s the corners and edges that will begin to peel up over time.

I’d thought about aluminum trim, like is used on doorways and windows, but I don’t like the look of it.

What about using something like this?

http://www.homedepot.com/p/TrafficMASTER-MetalDecor-Cherry-72-in-x-1-3-8-in-Carpet-Trim-18511/202066481

Easy to install and from a distance, should look just fine.

I’d use brass stair nosing screwed down, like is used on a landing where carpeting ends and the stairs down begin or what they use on stairs that have vinyl on them.

I think I would just use 3/4” banding and cut a small slot- rabbet in the top edge of the plywood to tuck the edge of carpet into

I would just butt the carpet up to the trim, and put a bead of clear silicone around the edge. It can be done cleanly enough that the silicone doesn’t even show. I don’t think you need any kind of lip or groove. I did a church pulpit with a platform they stand on and did it the same way. No trouble thus far, been about 2 years

Thanks for all of the input, guys. After thinking about it, as much as I don’t want to, I think I may go with the brass or aluminum stair nosing. This podium is going to have casters bolted to one side, so it can be stood on edge and wheeled out of the way. It’ll be stored in the back corner of the stage, probably shoved in there. Since the top is slightly larger than the base, that’ll probably get hit, and it won’t take long before the cherry shows the abuse.

Hi Ed. I am a music teacher and conductor of orchestra at a high school. Will the trim piece at the bottom where the music goes, be 1/4 inch? That may be a little small for the scores that the conductor will be using. Is there any way to increase the bottom piece for holding multiple scores? Or is there a shelf of some sort that they will use underneath. Don’t want to change your design as I think it’s fine, but just the bottom lip where the music will hold I would want just a hair taller. The one at my school is almost 1 inch

Kaleb, I may have done a poor job describing what I’m building, there is no spot for music on it. I’m making a version of this. Here is a picture of Cindy’s :

Oh ok. So it’s a table top thing. That should work nicely then. Carry on

The brass strip might also provide some grip/non-slip for stepping onto platform…if person puts their foot on edge instead of fully on platform.
