Alt 8:1 reeve

Can anyone post the alternative way to reeve an 8:1?

Thanks

... And I gave you hints ...

Ok, since I don't know how to post pic's/diagrams I'll walk you through it ... maybe someone can post a pic or diagram

1) Start w/ a Harken Quad Block for the top "Boom Block" and a Triple Block w/ becket and camcleat for the Bottom "Traveler Block" Now you need to modify/add to the bottom Block a "Single Block" attached above the camcleat to a eyestrap that you install on the (2) mach screws that hold the Camcleat on. Now here is the "BIG TRICK" ... the single block must be installed so that it is orientated across, orthogonally (that means 90* to ...)to the triple block ... I tie mine on w/ 1/8" spectra/vectra ... OK?

Now wreaving/threading as follows ....

2) Start w/ the mainsheet passing through the Triple block at the camcleat and center shive .... (the mainsheat exits the triple at the back).... up to the Quad Block to the second shive on the left (this can work both ways, I just picked "left"), thread the mainsheat through over the top from back to front ... next down to the Triple Block to outboard left shive, threading the mainsheet from front to back ... continue up to the Quad Block to the outboard left shive, again threading the mainsheat through over the top from back to front .... NOW FOR THE TRICK .... continue w/ the mainsheat down to the SINGLE BLOCK(!!!) attached to the Triple at the camcleat, threading the mainsheat from left to right through the "single block" ... now up to the Quad Block to the outboard right shive and thread the mainsheat through over the top from front to back ... now down to the triple block, threading the mainsheat through the outboard right shive back to front ... continue up to the Quad Block, the inboard right shive and thread through over the top front to back ... continue down and tie off at the becket on the triple. There you have it ....

Now when you weave/thread an 8X1 Mainsheat Stack this way you will notice that by having the "Single Block" attached to the camcleat the mainsheat will not rub anywhere as it crosses from the left side shives to the right side shives. This works best if the "Single Block" shive is the same size diameter as the "Triple Block's" shives (ie: smaller is NOT better). I use the Harken Quad as my "Top/Boom" block as I know of no other manufacture making a "Quad Block" (but there maybe someone) For the Traverler/Bottom Triple w/ Becket and Camcleat you can use any manufacture you please ... I determined my preference based on the finer adjustment ability and on the angle of the camcleat ... (I like Lewmars personally ... but the Harken "Carbo" series is good also )

(I can't explain "how" I can do this, but I can close my eyes and visualize things in 3D ... rotating it and viewing it from different angles ... something that amazed my Architectural/Engineering Drafting Teacher in those ol' days where you actually used a lead pencil and drew drawings on paper ....)

Thanks Harry, Cheers!

Seeming as though Ben Moon doesn't come here frequently, i'll pitch in

Thanks but i am lookking for an image of how to reeve (run the lines), not of a quad block

Like this?

http://www.harken.com/OneDesign/F18.php

No Tony (but thanks)
That is the same method as i posted in this thread - http://www.catsailor.com/forums/ubbthreads.php?ubb=showflat&Number=244097#Post244097

someone said he had an image and to PM him, but he has not responded to my 3 requests.

What kind of blocks do you have?

I have mine almost identical to the pic in the other thread, with the exception that I swap #1 and #4, which uncrosses them.

harken 8:1 (upgraded to a 9:1 - I added a double eye-spliced line through the top quad, added a 40mm below)

ratch-o-matic 57(?)mm

ditto yurdle, but it was mentioned in the previous thread (above), there is a better way to run the main.

It's easy:
- Create your message using the "post reply" button at the top, instead of the "Quick Reply" box at the bottom.
- Click at "File Manager" (below, at Post Options)
- Select your file
- Click Add File
- Click Done adding files
Then sumbit your message.
You will attach the file to the message, it won't be visible yet but from there anyone can make it visible and can explain how.

Ok, Step 2:

After sumbitting the message with the attached file, you will edit it to put the image:

- click the link of the attached file on your message, the image will open (on a different window)
- Right click on the image
- "Copy image url"
- Go back to your message
- Click Edit
- Place the cursor where you want the image
- click at the "Enter image" icon
- Click any of the options (non floating, left, right,..)
- At the text box, right click, "paste"

There you go

Scroll down to the bottom of this page mate....

Thanks but that is not the same.
That one has a double block on the bottom becket, i added a single and still have 9:1

oh well, just trying to help mate....

I think this is what Harry Murphey means.
At lest, this is a kind of exploded view of what I see in my mental image of his description..

Yep ... that looks like it ...

Harry

Thanks to all (including engineer for trying!)

I stumbled across it today. It's in the hobie tiger manual. The blocks aren't perpendicular...never seen that before.

Hi,

If you look closely at the Hobie Tiger Manual illustration you will see that it shows a "right" threading/wreeving. I had discribed a "left" threading/wreeving. Both work ....

By "perpendicular", I meant the orientation of the small single block and how it was attched to the lowwer triple block w/camcleet. Origonally when I purchased my TheMightyHobie18 w/ a "Big Block" Harkin 7X1 Mainsheet Stack the "single" block was orientated in the same direction as the triple block .... but .... the sheetline rubbed/chaffed on the center sheeves.

So one day after finishing racing for the day, I sat down w/ a "beverage" and studied the situation/problem ....
