General Winter Camping Discussion / Re: My winter shelters
« on: November 07, 2019, 05:44:07 pm »
I agree with the iglu for sure, although I have not got the build time down below 4 hours yet - I'll try another couple later this winter if we get the good wind drifts on Lake Winnipeg.

A second best shelter would be a cotton hot tent with a separate waterproof fly, a load of dry dense wood in a tight stove, and with a fully covered floor (thickly woven boughs, or closed-cell foam).

I've used one of BV's canvas bags for a few years now for my school's large tent (similar volume to your snowtrekker, DFN.)

They are great! BV has packed many, many tents and knows what design of tent bag makes it easy - especialy on a cold morning with a stiff, frozen tent.

The big, wide-mounthed opening lets you squeeze a frosty, ornery tent into submission without any fear of damaging the bag or breaking a duffel zipper. Then the two parallel compression straps allow you to close it up, tuck in the bag flaps, and cinch the whole piece into a tidy, sled-friendly packet.

Once back at home, and after the tent has hung and is bone-dry, you can fold and wrap it up small and snug in the canvas bag till your next trip out. While stored the bag and tent can easily breathe through the canvas - a very good thing.

We have definitely found that life is simpler when the poles have a separate bag, and are packed in their own place on the sled.

I think Snowtrekker may be using fabric that begins as 7oz. tightly woven cotton, and then the weather-proof treatment is added. The resulting combined weight would be higher than 7 oz./sq.yd.

So, your 8oz fabric, if that 8 oz includes treatment, may be lighter weight overall than the treated Snowtrekker fabric.

Can you post the UK website, AND?

I'll always buy the butter tarts BV, if you keep making the tents!

Apparently Whirlpool may be open, and Moon Lake will be open. They are a little less open to the wind, perhaps.

I'll phone again on Wed, Nov 6, and post their response.

Is the Audy site sheltered, or exposed to wind?
Thanks BV.

Or this one? You could raise it by 45cm, adding breathable poly walls with snow flaps? "Only" 6 pull-outs/anchors, with no required pegs.

The vertical front wall could hold a vertical zippered door on one side of the pole.

Might come in at less than 1.5 kg.

Hey BV, it might be that 17.5 sq ft may be a bit tight for you your stuff, and that hot little stove.

That SD tent is so light that doubling the floor space might only add 1.3 lbs to the weight.

For me, those sloping end walls might really reduce the usable floor space. The thicker winter sleeping pad and thicker and longer winter sleeping bag lift the sleep system up into the air space, and it might rub against the slope.

The overall weight would be delightful!

Hey BV,

While doing similar deducing of my own I figured that a solo shelter could have vertical side-walls rather than sloping tipi-style walls. Vertical walls might:
  - use less material than longer sloping walls would (cheaper, lighter weight),
  - allow for a vertical wall for your door zipper (this would reduce dripping from a sloped door opening onto your gear),
  - have a smaller tent surface area (therefore warmer because of less heat-loss through the tent material),
  - need a smaller space to pitch it upon,
  - require a smaller floor covering (lighter weight ... assuming you are going to haul a light-weight floor covering, or are going to cover the floor with bows),
  - allow the usable-space-to-floor-area ratio to be much higher,
  - allow easier pitching as you are anchoring cord pull-outs a little bit away from the tent wall and not having to drive stakes right at the base of the wall, (means you could pitch it on ice or rock, too)
  - reduce the volume of the coldest part of the tent which is typically nearest the floor, at the lowest elevation,
  - have less total interior volume and so would heat easier with a small stove,
  - have easier wall spaces in which to install those double-pane window units.

OK!! I'm just getting carried away, now! Double-pane windows! What'll they think of next?!

Oh, I should add that this solo, with its short but vertical walls will be for pitching in sheltered spots only, not for pitching where it could get very windy - definitely not for an open lake shore, or above treeline.

Please let us know how the food box/tent table works out, Stormy! That and a new sled will make for fine Fall daydreams!

The is a worthwhile thread, BV, thanks for starting it.

If I'm lucky I'll get out on a trip with you guys again, BV!

The usual school hot-tent trips will happen for me, along with a short family trip just after Christmas, and a friend-from-away trip in mid-March.

Really hope to improve (what will become) the short route from Davidson Lake into Burton Lake. It will be great to shave 2 km off the distance, and avoid all of the travel on sketchy creek ice. This trail making will take 3 full days of cutting, I think.

It wil be fun to try out the new solo hot-tent, and the new mica stove window.

The Farmers' Almanac predicts a winter with moderate cold, with lots of snow - kind of the opposite combination than what would be optimal, but who knows? Maybe we'll have a delightful 3 days of crust-making-thaw in February as we had 2 winters ago! That'll make for wonderfully easy travel in March!

Hey BV,

We are hoping to meet you at RM. at least for Nov 9,10,11.
Let me know if I can help find out about Whirlpool being open.
How was the quality and quantity of already cut wood last year?
Might hear a wolf or two howling :)


Other Winter Camping Gear / Re: Cheap LW overbags
« on: October 09, 2019, 03:55:36 pm »
This thread might have walked a little off the initial track, but...

I agree, Moondog, that buddying-up is definitely done regularly amongst adults on extreme winter trips, but I want to note that "best practice" on Cdn school trips would NOT include pairing or tripling students in the same sleeping bags or under the same overbags - too many personal space issues with that one. Of course, once the emergency besets best practice becomes more practical and less political.

In my experience body-to-body warming is not as safe, efficient, or as practicable as are hot water bottles/bags combined with that warm down bag you've mentioned, for mildly hypothermic youth. Treatment for severely hypothermic individuals in the field would typically be temperature stabilization only - using the insulative down gear you mention - with rewarming done at a medical facility.

My thoughts exactly!!

So, I am procrastinating for another year.

Over these next 12 months I will get my gumption up and, finally, attend the damned event in 2020  .... if I have to.

While you are there next month can you steer the conversations toward more palatable topics....choosing window drape colours, or precisely when to use or not use that second dessert fork in our formal dinner settings?

Would love to go, BV, but work has me booked for that time. I have told them that I will be going in 2020. They agreed!

Fire and Woodstoves / Re: Reskinning a stove
« on: September 03, 2019, 10:47:33 pm »
Just to complicate your decision-making.....

Might you consider leaving the warps as they are and cutting a hole in the top that matches the size of the base of your pot?

(Full disclosure here: I have a "ripple-top" stove too but I have not yet mustered up the gumption to fire-up the jigsaw and carve out a hole!)

GWH stoves have always had effective cooking holes.

I can attest to significantly better heat transfer from fire to pot base when a hole cover is off. This increased efficiency is especially apparent when your tapered pot nestles a few cm down into the flames. Don't want that much heat on your frying pan? - just slide a flat disc over the hole and reduce the direct radiation.

IF this solution worked to your liking, you might have solved the problem AND reduced your stove weight.  :)
