MYOG High sided bathtub groundsheet

[Teepee]

Extra high sides on this new groundhseet (15cm), along with obligatory orange trimmings in my obligatory orange tent. The foot/quilt/bag cover section has been in solid use with me for a couple of years now. It stops me lifting my feet in a morning mong, and stops the foot end of my insulation getting damp (the only source of damp I ever get sleeping like this).

Unlike the umpteenth models before it, this one attaches to the existing tent pegs and has not only a tension adjuster, but an angle adjuster to help it pitch straight on dodgy and lumpy pitches. Also, it's held off the ground a little bit to help stop abrasion. Much wider than normal too, at 1m. Previous G'sheets have always been 50 to 75mm high on the sides before, and 80cm wide.

Square shape so that bags can go at foot end, either side depending on the lay of the ground.

Is that a SUL flower pot

That's what I wanted you to think. It's actually a terracotta snow basket, cunningly disguised as a flowerpot.

I thought you might have disguised a titanium one by painting it pink

That looks really nice Pete

Almost enough to tempt me to try a night without a full inner.

Join the dark side JKM!

Fierce !

Great work as usual. Still love the tent too!

 

[Dave V]

Nice!

 

[Shewie]

Good job mate

Should hold a bit more liquid

 

[Ken T.]

Might give that a go. Thanks for the inspiration.

Dreaming of it filled with Rioja now.

A pleasure. These are nice and easy to do once you've got the corner struts sorted.

My thoughts exactly

 

[ClimbingUke]

@Teepee What do you use for corner struts?

Drilled out Unicorn ivory.

( or it may have been Delrin, a stiff type of plastic rod)

 

[ClimbingUke]

Thanks. I like that ivory!

Looks great indeed. Care to share some construction details on the corner struts? They look really clean!

I've been asked to do a tutorial and very likely will, but it's going to be in a few weeks at least. I have more important things to do, like playing in the snow.

There are loads of ways to do the corners and TBH, it's hard to get them really wrong. These were sewn with the insides together to form the flap (after hemming) and very simply wrapped around some tape to from a re-inforced channel, then sewn along the edges of that tape. That tape is then sewn to form the loops and hold the stiffening rod inside. I'd have used LL3's, but have run out...... so used the 1g each cordlocks you see. They grip the 2mm bungee very well.

 

[KVerb]

Thanks for the explanation, still looking forward to the tutorial

 

[tullochgorum]

I'd appreciate the source of the 2 oz PU coated black ripstop Nylon 6 6...

 

[Karl]

I still have and use version 2.0 with the 2.2 modifications wicked bit of kit will definitely be commissioning a new style one to go with the new tent. I don't go camping without it if I'm ground dwelling.

Having decided that a bivvy is not for me under my Trailstar and Cricket my mind has drifted to high sided bathtubs. I like lot of your design features @Teepee but I'm wondering what you think about even higher sides. The benefit would be draught reduction and ultimate breathability. The cover at the foot end could go a bit further up to hold up the sides. What do you think?

 

[Odd Man]

I've no experience with bathtubs, but I was wondering if there are any that use a long Ti nail as a corner rod and a peg at the same time? Would that even make sense to just have a channel to put the nail through like with tent poles?

 

[Tartanferret]

The Ti nail would need to be huge and the bathtub would still not be as taut as the other approach. No “give” either.

The maximum potential height of the sides in my shelter is limited. Any higher and condensation may run down, hit the tub perimeter and pool inside.

It is a bathtub though.

I've often thought of trying higher..it seems as though deminishing returns would be seen as it get progressively higher. Maybe angling the sides inwards is the way to go. Undoubtedly though, higher sides would stop more wind; especially when used alone

FWIW, I have a another run of these to do and want to do a modular approach where I can switch a bug net top for a bivy top, or a combo of both.
I put a removable bug net on it last summer, which really held the sides up very well.

This one is still my best 'tub ever. It's kept me bone dry and comfy in the tent for hundreds of nights now. That cover at the bottom has stopped everything from getting kicked out at night and has kept my feet warm.
