Parts supply

I don't know why with all the macs out there but trying to get parts was always difficult until I discovered Blue water yacths in Seattle is the official Mac parts supply. They have a lot of things like rigging and hardware impossible to get elsewhere.

Don't know what they have for the 25 - but they are a good bet.

wire size

I measured my shrouds....they are 5/32" diameter. Forestay and backstay are both 1/8" diameter. I think Blue Water has them, but you need to send hardware and old wires for length. I bought a crimper and did it myself. It is a bit tricky to bend around a thimble eye because they are so stiff. Can be done with patience.

Good Luck!

MrMikey have you been over to Minney's Yacht Salvage in Costa Mesa? I don't think it's too far from you. He has quite a few toggles and fittings. I bought a new Johnson bar from him with forestay for $20. I rerigged mine at WM. Buy their cable and fitting and use their tools. I wish I could remember the length for you but I used the old ones as a guide. If you can find someone with the boat down I would measure them myself. I used 5/32 ss 7x19 cable as opposed to the 1x19. It is more flexible and IMHO lends itself to trailering better. I think it is less likely to fatigue and kink, especially at the spreaders. Much easier to work with too. It is not as strong as the 1x19 but well within working loads.
I have no idea what riggers do but the following worked well for me. I looped the cable through two ferrules and then clamped about a 1/4'' in the bench vice. I inserted the thimble in the loop and pulled the long end of the cable so the loop was nice and tight against the ferrule. I then used WM's crimpers to crimp the ferrule next to the thimble. I then took the loose ferrule and slid it down flush with the exposed end of the cable to prevent snags and ouchys. They turned out pretty nice. They have been on for a year and so far so good.

Just a little extra info about swage fittings: the original development was done by Bell Telephone Labs. The second swage on a wire makes the cable no stronger, it just covers the sharp end. There are two swage metal types, copper and aluminum. A thimble can have the little "ears" cut off, if you are having trouble with the little points and holding the wire tight before swaging. For best results, understand that the swage material will flow away from the swage point. Make three crimps on each swage, do one in the middle, then on each end. When choosing wire, know that carbon steel may be just fine for a fresh water application, but use stainless if you can find it. A good source for technique is AC 43.13-1A, an advisory circular from the FAA, which can be googled on the net. Good luck

Oh yeah, when we were duplicating the wires, we drove nails in the blacktop in the street, with the old cable strung from nail to nail. It was simple to duplicate the length that way. This would be the time to adjust the rake in your rig. John S Boise

Hey John,

Thats how I did mine.... with the blacktop/nail routine, but was afraid of somebody rolling their eyes. (been restoring/flying old airplanes for 25 years)

The AC 43.13 thing will only overwhelm most guys not involved in airplanes........WHAT IS THAT?

Losing a mast probably not as bad as a wing spar

I did score a crimper at home depot for $30. Does a nice job. 1/8" smallest. I think it has 5/32 and 3/16. Anyways.....good reference material for the perfectionist....(isn't that what we all strive for

)

See Ya,
John

still have my original 43.13 from my IA days.......:dance:

.....forgot to mention.....Frank. That flexible cable is easier to bend, and will work fine, but plan on tightening the rig a bit more often, cause it will stretch a schoce more........something to do with the physics of the multiple strands..........personally, I would stick with the 1x19 stainless. It will kink if stepped on, bent,(ultimately breaking strands at the kink) so care is warranted when trailering.

Sorry......I missed that. Check BWYachts. They will have it. You will need to call them, because I think they need your old fittings ( I think they have fittings too). Macs generally don't use turnbuckles. I can measure mine, but that assumes a Venture is the same as yours. Measure mast base to hounds/spreader. Measure your spreader span. What type of backstay do you have? Here is a link.........J

PS.....break out the old sine-cosine books and get close enough for the adjusters to do the rest

rigging

You will need 5 sets of adjusters(male/female), 4 tangs, nicopress sleeves,thimble eyes,wire and some patience.

I have a split backstay adjuster whichs works great. My forestay and backstay end at that masthead with a thimble eye/clevis pin terminal.

Flynfol,

I am still working in the trade for UPS Airlines. I don't get to do much more than babysit computers these days, other than brakes and wheel changes. I referenced 43-13-1a to defend the assertion that one can cut off the little points on the thimble, I get a little defensive these days.

One thing I bought was a go-no go gaige from aircraft spruce and wired it right to my swager. I also have an extremely small swage tool for those lanyards for parts that just cannot go over the side- like the forstay pin nad boom pivot pin.

By the way, I use "pip" pins on a lot of my rig points that would otherwise need a nut and bolt, or a pin and ring ding. My fingers are clumsy, and I have donated so much to Neptune!

I also have an adjustable backstay, just a single with a 3 to one block set up. The best thing about a set up like mine, is that when its time to put the mast up, I have the backstay disconnected, and it does not snag on the outboard or boarding ladder like it always did for me. After the mast is up and pinned at the forestay, I attach my adjustable backstay.

rigging

Hi John,

I'm still flying out of Chicago(corporate). Sailing is my escape from the fast pace. I was joking about the 43.13. That will always be excellent reference material. ('cept maybe avionics repair) Just about everything written by the FAA/CAA was printed in some poor sob's blood. Have seen many nasty nicopress/thimble installations before.....yikes. Love flying, but I don't daydream about it like I do sailing.

See Ya,
J

Rigging info...

I rigged my 26D with 5/32 x 1-19 316ss and Hayn fittings from Rigging Only, www.riggingonly.com they had the best prices. About 1/2 the price of WM. Though in WM defense, they were willing to price match. Unfortunately they had a 4-6 week lead time v/s immediate delivery. As for length, measure your for and aft deck length. lay the mast on the ground and measure the triangle. Add a few extra feet for measure. Good luck and happy sailing.

Hi- checked my 26S Rig Box Checklist and it uses 5/32" for the sides and 1/8" fore and aft, so I'm sure that would do for your 25.

I also checked a couple of catalogs. Both West Marine and Defender carry 1/8" and 5/32" 1 x 19 wire as well as 1/8", 5/32", and 3/16" 7 x 19 wire. According to both catalogs, the more flexible 7 x 19 wire is recommended for running rigging, and 1 x 19 for stays. The 1 x 19 is also slightly stronger. I'm sure if both of those stores carry the wire, some others will, too. Prices vary considerably, so shop around.

I would do the boat and mast measurements as suggested by other posters, lay it out on your driveway, street, or parking lot and measure your needed lengths (or alternatively, get the measurements and work it out with trigonometry). Try to get close enough so that your adjusters or turnbuckles can make up the difference.

Good luck. -Paul

Mikey, you know some people do replace their forestay with a little bigger cable, especially if you decide to add a furler.
