portawrap dimensions

[finchy001]

hi all,

 

i wondered if anyone could help with telling me the dimensions of a portawrap.

 

mainly the pegs used to tie off the rope, i'm assuming its 10mm steel rod, but i havent got access to one to measure it up.

 

if anyone could help it would be greatly appreciated

 

cheers

There are many styles and manufacturers of porta-wrap style devices. If you are more specific i'm sure someone could be of help

Hi Pete,

 

Really just looking at something along the lines of the ISC small portawrap to begin with.

Hi Finchy,

 

I've made a few of the Buchingham-style portawraps. The smallest ones I've made used half inch bar and 3 inch tube with the same bar for the ventral peg on the 'nose' and the T-bar on the 'tail'. It was OK - only. Testing the prototypes on my nephews' workshop gigs it was still only worth using for light lowering. Maybe better than a fig 8.

 

The latest and biggest one made uses 1 inch bar surrounding a 4 inch tube! Now this item is much more useful - providing a better bend radius for the rope and generally more working room. Distance from bottom bend to top bend would be about 14 inches and the tube is about 12 inches.

 

Hope this helps.

Thanks alot WeeDee, I'm just tinkering with designs for now, and I think I'll over engineer the first few to makesure they hold and do the job thats needed of them.

Aiming to make a device in the style of the new RC range that has the drum mounted onto a plate aswell, will keep you informed of how they shape up

I'll look forward to hearing about it.

Just dont make it too alike as RC is a member of this forum

how do homemade devices stand in LOLER terms, obviously welds wlil be xrayed to ensure quality, but do they com eunder the basic loler inspections along with other kit, or do they find themselves subject to more stringent assessments?

I dont think you could LOLER a homemade portawrap????

 

Surely it must need a rating and CE marking??

oh yes...i think you'll find anything you make will have to undergo a lot of testing at considerable expense....thats why most ideas never get past "ideas"
