TcluffWhat should I use for coping I am putting an hdpe sheet on my box but I forgot about coping should I use pvc pipes or steel bars? Or is coping even necessary?
I replied to your other thread as well. Steel all day.
You can bolt it onto your existing box. If you use pvc, while it can work, it's not the greatest and sort of defeats the money you already spent on the hdpe. If you're going to use pvc coping, why not just have just used pvc all the way kind of thing.
You can drop a 2x4 down on each side of the, Drill holes through the one side of your steel tube so you can fit the bolts/screws. Then drill it into the side of your box. You can do drill it from the side so that you don't even have holes where your skis slide.
If you build your box strong enough and bolt the steel on solid, it will feel as solid as a box at the ski hill. I would def bolt it on though. You can screw your top sheet down but the steel is heavy. If you're only going to have it attached in a couple of places run bolts and get them nice and snug.
You likely won't be getting a ton of traffic in the backyard but if you get any burrs from hooking in your ski edge, just keep a file around and file it down till it's smooth again.
Just make sure you frame your box out well. You want it to be rock solid. Also make sure you do a decent job on the rungs that will support the top sheet. Might not be a bad idea to use 3/4 ply or double up. Probably unnecessary but why not. I've seen wooden boxes at ski areas that started to sag in the middle a bit. I'm not sure how they were framed but the box had a curve to it. The top sheet and coping were flush, but the middle was noticeably lower. It felt weird to surface swap.
If your framing doesn't suck and you bolt the steel on well, countersink your heads on the top sheet, and get everything flush, it should feel pretty much identical to the boxes at your resort.
Also if it gets sticky you can throw some silicone spray on it or just keep that shit moist.
i just woke up and my brain is stilll half asleep but good luck
