Making a "loupe"

[glynn]

Thanks Guys ,
It 's all clearer now, but I think I'll pass on these for a while .I'm still struggling with an eye splice in braid on braid.

It's in the splicing handbook.
Fair leads,

Which book exactly?
"Working Rope #1"? #2?
"Complete Riggers Apprentice"?
Also, are your books available outside of Washington?
I would love to be able to thumb through them to make sure I buy the right one(s).
Anyplace near Annapolis, MD?
Thanks,

I will be using this material next month for the structural seizing binding the pair of shrouds each side on a gaffer we are working on, and the deadeye into the spliced eyes on the wire, and will let you all know how it works out.

I think the harken loupes made by Yale are indeed a many wraps of small stuff and that you could make your own, as I have been doing. they are reported to get stronger with use as the strands come to bear even load through cyclic loading.

" I first made a loop, then made a locked Brummel, then buried each end till it was a good ways around the loop - ends were tapered over 2-3 inches or so. Then did a bit of stitching to secure it when not under load."

maybe I am way behind the times, but I haven't figured out yet how to put a locked brummel into a grommet, whatís the secret ?

Brian, I have had good results splicing both the Dyneema flat twines and 3mm Dyneema with a buried tail McDonald Brummel as shown in Brions book.

We have designed our own fittings and had to come to the reality that the outer cheeks where the standing part of the rope goes around had to be a little shallower than a traditional block. This made it possible to get the brummel eye over the the cheeks and into place. We made the cheeks longer to compensate the angle of the splice and get a fairer lead. I learned you need to take the splice and really yank on it to open it up before you attempt to get it over the fitting.

We are just now coming out with new deadeyes that you can use on both ends of a shroud or backstay.

Please check us out at http://www.colligomarine.com/ go to the synthetic rigging link.

I want to get some of this new stuff to Brion to work on and get his feedback.

Back to the future.

Jack,
I have also had great fun splicing all sizes of all lines, and have now found that NO line is impossible to splice, with all the variations out there.

What I have not been able to figure out yet is a LOCKED BRUMMEL with a continous loop of line (grommet). Brion has said it is in his new Splicing Handbook, but what fun I have been having trying to figure it out myself, inverting flipping and tucking till the wee hours of the morning...

I guess soon I might just buy the book, cause it is not comming to me !

Hello everyone,

One question that has been bugging me is the longevity or strength of the Loupe or HM grommet. In most all literature, they specify 8x the line diameter bend radius. I imagine that this spec is for running rigging, but it makes me question what kind of trade-off is there by using a Loupe around a pad eye? Any strength degradation? Would this be a weak point in the setup, or do you just go up a line size to take care of it....

Just wondering...

Jim

OOH OOH!!! I know!!! I remember when I took the advanced splicing class Brion sent us home one night with homework- see if you can figure out how to splice a locking brummell into a grommet. I was camping at Ft. Worden State Park that night and spent a while next to the fire trying to figure out how to do it....then it dawned on me. I had to cheat, but I figured out a way to do it.

I remember coming in the next day excited to share what I'd done. As a matter of fact, I wrote down Brion's response, because I didn't want to forget it!

Trust me, get the splicing book. It's well worth it even if it were JUST for this one tiny tid-bit.

love
