So I should be expecting delivery of my OSR2+ soon and I’ve been thinking about possible ways to mount, mainly for lying down but also for kneeling in bed. I’ve seen some ideas from others but yet to see a “mega thread” and also to me, none of the mounts are quickly adaptable for lying down and kneeling.
The idea would be that it would be used lying down, and then can be “tipped over” for standing/kneeling scenes.
I’ve drawn something up quickly on sketchup. With no experience of the device (and designing for that matter), I am unsure if this will be suitable and wondered if anyone had any constructive feedback or additional comments / ideas. I know there are a lot of talented people on these forums so I am expecting some
Hi, the idea of having something properly made so you can lay down etc with the device mounted sounds great.
For you initial design i feel like having something attached to it that you can sit on to keep it in place might be a good addition? or perhaps that will go under your thighs / kneel on depending on the orientation so it will be hands free.
So this is part of it — I’m not sure how much force will need to be overcome to keep it in place/stable.
Ideally whatever I build would be self-supported as I imagine something pulling up on your legs would hinder immersion, and would also make it more tricky to “flip” or get in and out of — so this would need to be achieved through a combination of weight/stability-by-design, although there could be a problem there given a mattress is inherently unstable
In terms of materials, I’d likely prototype with wood and open to the posibility of using aluminium profile for the final version. Even steel scaffold tube could be used as a weightier option, which could be filled with concrete — I’ve fed the measurements into ChatGPT and for all the tubing, clips, mount, device it comes to 20kg, and 28kg if tubing is filled with concrete — aurely this is enough to be stable?
It’s easy to make a product that fits one dimension. This product, though, needs to account for multiple. When you get up on your knees, is your peen not higher on your knees than it would be laying down? It’s logistically impossible unless there is a way to adjust the height of the receiver to accommodate both positions. It’s possible but expensive and probably won’t last long for a hobbyist build. And if it’s just rigid, it won’t be that comfortable.
In the frame pictures, it’s 24cm to the center of the receiver lying down and 34cm when kneeling.
the difference in height between lying/kneeling depends on where the “mount section” is positioned across the yellow plane, as this doesn’t adjust the height when laying down but does in the kneeling position. Similarly, the lying height can be changed without affecting the kneeling height.
Current design aside, I do like the idea of making it out of scaffold tube/fittings. Not only is this a stable option due to weight, it’s easy to source, heavy, robust and adjustable to an extent with “T” fittings which secure with a hex key
Here’s an updated design using scaffold tube and fittings. The wooden mounting board attaches to the tube with double sided fixed brackets.
I’ve extended the legs for increased stability, which consequently means the device would be angled in the kneeling position. I’m not sure whether this is better or not.
At 20kg is this heavy enough to be stable during use?
If additonal weight is requied — the third option for filling would be to use steel shot at a 50/50 ratio with concrete. The steel shot would cost roughly £40 which bumps the price up quite a lot. However I imagine the empty unit would be sufficient.. but happy to be corrected? As I said I have no practical experience with the device so hard to gauge
