    Anybody have an idea where I might be able to find the pulley clamps shown in the attached image? I've got a source for the ball-bearing pulleys (blocks) but am coming up blank for the clamps that attach them to frame rails.

    TIA,

    Kent, I've never seen that style of clamp before. They appear to have a hinge built into them. Do you think that electrical conduit clamps might be made to work? On my Supercat I was able to mount a small pulley to one of the clevis pins on the frame. Good Luck!

    Kent, try fisheries supply in seattle on northlake. Or look at their web site www.fisheriessupply.com , Sail boat rigging lots of different pulleys with clamps etc. Jim

    I bought an anchor system for my cataraft from NRS, the best one I have found anywhere.

    Look to me like ordinary pipe hangers. Try ACE hardware, Lowes, Home Depot.

    Those were specially machined at one time. The clamps anyhow. I'm sure they can be bought somewhere, where I have no idea. But I know Skookum had the "in" on those clamps for the longest time.

    And those clamps are topnotch. Been using them for years, and have not failed. Even when I used them on my big 16-18' cats with monster anchors. Never failed. Try contacting skookum.

    I wanted those clamps for my blackbear frame too. I wcouldn't find them anywhere. I searched everywhere including all of our industrial catalogs here at work. What I did was used some clamps that Yakima uses for some of there car racks. So for I haven't had a problem and they are real similar in design to what bill days uses except they are plastic. Seem strong so far. I can get a pic later if yo want to see what I did.

    Kent,
    Are you going to put this system on a Steelheader? If so I have come up with a similar system that I have put on my boat and a few of my friends boats. The whole thing can be done under $100. Check out the Clamp-On" Pulpit Block from Schaefer Marine, This is the block I used to go from the anchor block to the ratchet block. (to run the rope around the frame) As for the anchor block, drill a 3/8th hole in the top rear cross bar and use a stainless eye bolt to hang your anchor block. You can use a block from Ronstan, Harken etc. for your anchor block. Up front in the drivers seat you can use the same "rope ratchet" that Steelheader uses connected to the frame with a galvanized conduit hanger. Everything used was bought at Fisheries Supply in Seattle but you can also find it all at Boaters World in Fife. The whole thing is set up for 5/8ths rope. I have pictures of my system but my computer is not allowing me to upload them so if someone wants to see them I can email and hopefully that person could put them up here.

    This one was the key part and the tough one to find.

    You are right Mike, West Marine is the place, not Boaters World. West Marine is the store near Sportco across the street from I-5 Motors.

    DaMurph sent me photos of his anchor system which we was unable to post. Questions regarding them should be directed to him, not me please.

    Thanks Mike. The elusive component isn't the blocks but the clamps that hold them.

    DaMurph: I recently bought a used Scadden Skykomish Sunrise that has a cheapo in-frame anchor system. I'm considering adding the larger rear deck I built for my Osprey to the Scadden frame instead of using the aluminum plate deck that came with the boat. If that works, then I'll need a replacement rear anchor pulley since the Scadden one is attached to the aluminum deck I wouldn't be using.

    Since the Scadden pulleys are simple nylon rollers on a pin instead of nicer ball-bearing ones, my guess is that it'll take a fair amount of effort to use it to pull up a 10 or 13 pound anchor. If I can find a reasonably priced source for the components in the photo above, then I may just use them to replace the entire Scadden system.

    You can tell I took the Evelyn Wood Sped Redden Course and passed with honors. Here are your clamps or at least what looks like your clamps. Who ever put that outfit together may be a machinist.
