what do you think about this set up

What are you going to use for a base? In other words...how will you get it to slide into the traveler track? Isn't the stock jib car machined or pressed into the sliding base?

I AM GOING TO DRILL OUT THE BOTTOM RIVET ON THE STOCK BLOCK AND USE A CLEVIS PIN TO CONNECT THE NEW BLOCK TO THE U SHAPED SWIVEL BRACKET WHERE THE OLD BLOCK WAS RIVETED ON THE ORIGINAL STAND UP TRAVELING CAR.
THEREFORE UTILIZING THE ORIGINAL TRAVELER.

OR, I CAN REPLACE THE WHOLE SET UP WITH THE NEW STYLE ROLLER FAIRLEAD SWIVEL CAM TRAVELER BUT IM WAY TOO CHEAP FOR THAT ESPECIALLY AT EIGHTY BUCKS EACH. EVEN THE STOCK STYLE (LIKE THE ONE I HAVE) ARE NEARLY SIXTY BUCKS EACH.

I COULD JUST REPLACE THE SHEAVE ON THE HOBIE BLOCK BUT CANT FIGURE OUT THE CORRECT ONE TO USE. I HAVE BEEN TO ALL THE HARDWARE STORES BUT NO LUCK. HOBIE DOES NOT LIST THIS PART ON THE WEB SITE.

Either one of these is far superior, and at $18 for the Tren-Tec cars, a lot less expensive.


The KISME cars will set you back $49.

BTW, I've never heard of "CompleteSailor.com" before, and the information about the Hobie Class Assn. on their web site is almost 20 years old. I'd trust a Hobie dealer who can give you some decent advice before an electronic storefront with questionable information.

HOW DO THE TREN TEC TRAVELERS WORK? DO THEY AUTO TRAVEL IN AND OUT OR IS THERE SOME OTHER RIGGING TO MAKE THEM TRAVEL?

COMPLETESAILOR.COM IS AN ONLINE RETAILER FOR CHEAP PARTS.

YOU GUYS KNOW MORE ABOUT THIS STUFF THAN I DO. SO ILL CONTACT JEREMY AT SURF CITY. I GUESS I WAS HOPING A DEALER WOULD READ THE POSTINGS AND ADVISE ME.

Please stop with the ALL CAPS postings. In case you didn't know, ALL CAPS is the equivalent of shouting in e-correspondence, and it's very hard to read.

Both the TrenTec and KISME cars use a shock cord to pull them to center and a line/sheave/cleat system to pull them out. This type of system is so common that it's been standard on new boats for over 15 years.

I replaced both of my sheaves by drilling out the old rivets and using a clevis pin and split ring with the new sheave. I bought Harken roller bearing sheaves at West Marine for around 12 bucks each. I don't remember the Harken part number but I got it on this forum. Try a search. West Marine also had an exact match Delrin sheave (no bearings) for 7 bucks.

today at lunch time, i ended up drilling out the center rivet of one of the traveler blocks and making the sheaves out of dhmw plastic billet.
dimentionally perfect to the factory ones except for being a solid peice and boring the center hole to seventeen sixtyfourths (one drill step bigger than quarter inch) instead of using a bushing. talk about a cheap fix. and it only took forty five minutes from start to finish and still had time to eat lunch. wish i had a picture to show. they came out sweet.

but i gotta thank you guys for the suggestions
mike

Bushing's there for a reason.

sorry that was uhmw material i used for the sheaves not dhmw(typo)

the material i used is stronger, more abraision resistant and uv proof. very slippery!
besides the materials in the original part being inferior, the design was terrible!
the bushing floated, therefore allowing two surfaces to collect dirt and sand to cause wear and binding.(appearant by the marring and flat spots on the bushing surfaces and the rivet).
yes the parts were 24 years old but the new parts made will out last that by two fold easily.
even if the center hole wears it is still a solid peice.

Harken H160 replacement sheave?

thanks j_eaton and others.
that looks more like what i was looking for.
but i already got it covered im sure the parts i made will outlast me owning this boat cuz i want to buy a new 16 in a couple years, after i have learned how to sail (in over my head) so to speak.
