Gear problems and causes / solutions

Bushwalking gear and paraphernalia. Electronic gadget topics (inc. GPS, PLB, chargers) belong in the 'Techno Babble' sub-forum.

TIP: The online Bushwalk Inventory System can help bushwalkers with a variety of bushwalk planning tasks, including: Manage which items they take bushwalking so that they do not forget anything they might need, plan meals for their walks, and automatically compile food/fuel shopping lists (lists of consumables) required to make and cook the meals for each walk. It is particularly useful for planning for groups who share food or other items, but is also useful for individual walkers.

Turns out the bottle contained a dud batch. Manufacturer requested it be returned for testing and replacement metho burns perfectly!

I have a rather big problem with my plastic ski boots
Help and advice needed, even way-out ideas.
The black polyurethane heel pad in my Scarpa T2 boots has started to disintegrate due to hydrolysis.
I need to fabricate 2 replacements.
Before I go and spend any money what are my repair options?
Much wisdom and experience in the forum and I'm hoping for some good ideas

CCF or maybe a stubby holder cut to shape and glued. Depends how hard it needs to be. Rubber floor mat from a car? Glue cardboard together, make a filler using sawdust and glue, carve a piece of wood. Good luck and how's the snow camp going?

I've made a hole mould and cut some old acoustic felt to fit.
Should work well enough when silicon fills in all the small gaps

My macpac microlight is about 10 years old and the fabric is starting to sag having the problem no matter how taut I peg the corners out. It's annoying because the inside fly touches the outside material and leaks in. i have tried just tarp (no fly) but when i sit up or move around i scrape it.

is this the final days of it or is there a chance of revival?

7tm Telemark ski binding DIY repairs

Postby telemarktim » Sun 15 Aug, 2021 4:42 pm

Hi Tasadam and others, I hope my post is in the correct forum?

I have used (and some would say abused) my beloved 7tm Telemark bindings so much that all my skiing on/in them has brought about their demise. My DIY repairs and small modification to make them ready for backcountry/field servicing might interest others. The binding that needed the repair are the 7tm Alpine tour model with the step-in function (on the RHS of the photo). They are so nice to Telemark in that they get all the use (and wear) as I swap the binding over on a quiver of skis that all have the 7tm mounting plate fitted. The poor red ones (on the left) without the power bars get very little use.
Image

Alpine tour pivot bolt
The first repair involved the nut and thread on the main alpine tour pivot bolt. They had been gouged away by repeated contact with the opposing ski edge. "Yes, to all you Telemark experts, I do ski with my feet too close together!"

I have replaced the original bolt. The one shown in the photo below is my replacement from BJ Bearings. It is somewhat harder than the original but is still showing considerable wear. It will be cheap and easy to replace once more when the time comes.
Image

Alpine tour/Telemark lockdown button
The next repair was to the mushroom-headed button that holds down the Alpine tour pivot when Telemarking. It broke while away on tour (luckily on the last day). It would have been very difficult to repair without a comprehensive workshop. The main problem was the removal of the tiny pin that locks the rotary actuator arm to the button. It took considerable time and required a customised drift punching tool. Then came welding and grinding to repair the button. That was just routine.

The photo below shows the repaired button, after removal, welding and grinding back into shape. The repaired portion is slightly shinier than the rest.
Image

So, while I was making the full repair in my workshop at home I also devised a way of removing the difficulty of the pin removal task for future repairs. "I confess, I also lost the the tiny pin, but as far as I was concerned it was NEVERgoing back!"

Underneath the button, I substituted the stubborn actuator holding pin with a split pin, of similar diameter, that could be easily removed at any time to make repairs (as shown in the photo below).
Image

With the use of the split-pin, I even devised a backcountry temporary fix that would allow the telemark tour to continue with the use of a broken button, an old 4mm dia roofing nail and a backpacking multitool (or strong hands). I made the split pin modification to the second binding as a contingency for the future. That binding has earned just as many turns and may fail any time. Here is the nail option that allows the unused portion of a broken button to be used to hold the button in Telemark mode. The head of the nail conveniently locates in a groove to keep the nail in place while skiing (photo below).

Hey Moondog, How about silicone rubber that is filled or extended with those little glass bubble things that they use in fibreglassing? The composite should be light, even insulating and will last forever or at least longer than the boots. I had a pair of plastic boots where the outer shell hydrolysed and broke in two while skiing. Only found out when I lifted my snow cuffs on my ski pants and the top of the boot fell off. Lucky your damage is cosmetic by comparison. Are you back skiing?

I've got a pretty basic question.

What's the best way to shorten back pack straps? Just cut, melt, fold and sew? If so what thread should I use?

Thanks.

Also I'm after some shock cord for tent poles, quilt straps and a couple of other things. Any recommendations of where to buy?

Cams cords sell all sort of shock type cord, straps, buckles, paracord.

Brilliant customer service and on line sales from Brisbane.

Camscords.com.au I think

Before cutting a strap, make sure that the cut is in the right place. A builder maxim applies - measure twice, cut once. This applies to making sure that the two parts are the right way and not twisted. An overlap of about 30 mm should suffice. I use any poly-cotton thread that's the right shade. Start sewing slowly until the two parts are joined, then sew the other three sides, with diagonals. I usually finish with a zig-zag over the ends. A sharp needle is advised, preferably a heavier one such as an 80 or 90.

I normally cut to desired length and then use a lighter to melt the end so it doesn't fray. Practice on an offcut first so you get an even finish

Try a chandler for shock cord - they usually have it in different diameters. Whitworths should stock it.

Just make sure you get a bank loan before you enter Whitworths $$$

Thanks everyone.
That method sounds great lophophaps and I'll have a practice run on the piece I cut off.
I found online that Bogong in the city sells shock cord by the metre for a reasonable looking price so I'll try there.

Hi All, boating shops have a big range of good shock cords and they are very cheap (loose change) and of very good quality. It is best to hot cut or quickly melt the cut ends after the cutting. A bit stinky so do it outside on the verandah. I use the 4-5mmcord for tension/wet stretching compensators in each of the doubled-up loop cords on my silnylon pyramid tents and it is good:
https://timtinker.com/diy-breathing-polyester-tent-for-backpacking/

It also takes a good single knot if a simple stop is required. I have made an alternative tangle-free smooth connection to thin nylon cords by using stretching and whipping and binding with thread and silicone rubber in a similar way that is used to make DIY replacement speer-gun rubbers.
