How to Stifffen a Nylon Web Sheath?

#1
I have a machete with a soft'ish nylon webbing sheath which I would like to make in to a hard sheath. (I carry it sort of half in the top of my day-sack with the hhandle over my shoulder.

Before the fnaar fnaarr have you tried shoving a viagra doen there does anyone have any iddeas please?

I think there is something to do with glass fibre that might do it, but I know less about glass fibre than I do about nuclear physics.

Thanks in advance.

I was going to take the piss then I checked your location, Hong Kong, fair enough. The issue machete sheaths were quite stiff

I take it the problem is putting the Machete back in the sheath. I seem to remember the sheath having a metal "top" to aid the machete being fed into it. Would strengthening the access "slot" at the top of the sheath work instead of strengthening the whole thing?

Good calls all.

The problem is about half-way down the empty sheath where it goes in to the day sack. It bends it making it difficult to push in to the sheath past that point. I don't want to use solid stiffeners because of weight.

I've also thought about soaking it in PVA glue, but I don't think it would be strong enough. (Whatever I use I thought I'd keep it in the sheath wrapped in clingfilm and then Vaseline or KY as a release agent whilst whatever it is dries.

A thin sheet of plastic bonded or rivetted to the back of the sheath will add next to nothing in terms of weight.

Are you one of those blokes who cuts the handle off their toothbrush "to save weight"?

Makke up a dummy knife from a cardboard box or similar, wrap in clingfilm and insert into the sheath to give it the correct form. Get some glassfibre resin (it will be in two parts, the resin and the hardener. Mix in the ratio as recommended by the manufacturer. Mix thoroughly but quickly and coat the outside of the sheath with the mixture, woorking it into the material with a stiff paintbrush. Leave for 24 hours to harden. Bobs you uncle, job done. wear disposable plastic gloves throughout the job and preferably do it outside as the glassfibre resin is unpleasant stuff to get on your hands and stinks.

A simple but less durable alternative is to use paint or varnish on the cloth sheath as it will harden it up significantly but not to the saem extent as the glassfibre resin.

If it has a straight edge you could try one of those plastic Snap-shut strips you get on wood saws- Bahco ones have them. Or how about attaching the sheath to the outside of your bergen.

Araldite some stiff plastic onto back of it... or a section of light steel aluminium (such as the inserts in most bergans etc...or a metal rule.) Soak it in PVA?? Where are you cutting about...a school art class? That would disintegrate in humid air in about 30 seconds surely? Is this you do a bit of Ray Mears around the bushes in Fukin Park or Lai Chi Kok Park?
My pink hiking boots look good in the park.

The PVA idea was just brainstorming, although it has held well on some wood I've glued which is outdoors.

I think Blokeonabike wins today's helpful badge - I'll go with that.

Thanks again for the suggestions.

Bleach. Always f*cked up nylon webbing sufficiently.

Manfat. Make a party of it. Invite your mates & bukkake that sheath!

Go to where they sale UPVC stuff and buy a section of UPVC windowsill, should be quite cheap, only needing a small piece. Use that instead of floppy webbing sheath.

The Thailand solution is get a length of blue plastic water pipe, soften it with a bit of heat then flatten it and seal the end- works a treat

Yep, that's the DS solution. If you coat the matchetted blade in vaseline and then wrap in cling-wrap then coat again in vaseline and then place inside the nylon sheath that will ensure no 'stickies' on blade. Furthermore you can mould the nylon to the preferred contour, just ensure you can unsheath, hence the belt and braces approach with vaso & cling wrap.

Proven winner!

Sounds good to me. I'll just be careful not to mix this up with the bukkake solution otherwise I may end up with a permanent stiffy...
