I don’t think oils and synthetics mix very well. That rope needs to be shortened a bit. Has some major fraying on the end but I still don’t wanna mess with it too much. Dang winches are hidden pretty well on these new ATV’s Major pain to replace. The full wrap of rope on the spool should stop any slippage. What it does for rope wear will be a different and new issue.
Should work fine! My family used to have a 34" Ed Monk cabin cruiser. The bearings for the propeller shaft where it went through the skeg were made of Lignum Vitae and never showed any wear!
I think you'll end up pleased with those spindles. They should definitely outlast the previous one. Can you get the bolts drilled and tapped for zero fittings and grease hole(s)?
I used my ultra secret Tungsten disulfide powder on em. Friction coefficient much better than grease. What the weather will do to it is another story. TD or WS2 is actually a metal. Just a very slippery one due to its molecular structure. Not really something designed for weather tho. I look at it this way. Now that I found all the lost tools I can whip up a new batch in a couple minutes. Life is just a series of experiments. Hahaha
True enuff that you can obviously turn out some spindles easily enough Just seems that the damage to the poly roller was because it stopped rotating.. given that there may be insufficient lubrication. Weather probably played a part, but how many years were those rollers in service? If the wooden ones "lock up", it'll likely be the rope that fails. Would hate to see ya lose control of one of the monster logs you drag onto the trailer
Good point. The plastic rollers are supposed to be self lubricating,,,,to an extent. They’re not designed for what I’m doing with them. This self lubricating feature also plays a part in the failure. The synthetic rope also has a low coefficient of friction. That creates a scenario where the rope would rather slide over the wheel than roll it. They’ve only been in service just shy of a year I’d say. Once the rope slips it creates a small burn on the plastic which exacerbated the tendency to slip again. Technically the wood isn’t any different. It has a different coefficient of friction but it’s equally displaced between the bolt and the rope. What I’ve changed now is the full wrap on the wheel. This will essentially add 75% more friction between rope and wheel without accounting for the extra grip of a load. In my head I believe this will also lessen the load on the wheel and bolt connection. I originally just had the rope draped over the wheels. Roughly 25% contact for a low friction coefficient. This also put all the load force in one direction on the bolt. I think those bolts will almost float now as the load will travel right through the rope exerting just a squeeze force on the wheel drum. I’m sure there will still be some directional force due to the changing direction of the rope. My brain can’t calculate that too well but it should be less than before. I also drilled the holes 1/16” larger to allow for more clearance and possible swelling of the wood. Time will tell. Edit, just for clarification. This is for the log splitter picking up rounds. Not the trailer. Neither of those parts would stand a chance on the trailer
That will likely/hopefully resolve the slippage. Much like a capstan Most are on boats and are metal, with a much lower friction factor, yet still very effective. At this point you may need to keep an eye on internal wear. A bushing insert may prolong the pulley lifespan. $.02
Wouldn't be too hard to bore that out a lil more, insert a sleeve of the proper dimensions, and install a set of needle bearings...
Now if I had done more sailing I might have known this already LOL Do any sailing? Familiar with capstans? Just wondering how much wear the rope gets from coming into contact with itself? In reality it should be slight as they are traveling the same speed. I’m gonna find out Never considered a bushing. That could be effective. I have considered inletting bearings into the plastic. Sort of figured that’s just one more thing to go wrong and require regular maintenance. Both are always a possibility tho.
No sailing. I looked a lot into capstan winches for potential use moving logs in the woods. Still too slow for my liking, but effective. I've got some steep areas that the winch won't handle, and I'd prefer not dragging downhill towards myself and equipment. I've watched sailing and yachting, but no first hand experience.
Now.. If I had the skill set and the equipment to make a capstan winch that could be tree anchored, and use the quad to pull line, it'd be much faster n safer
Hmnnn, a little out of my wheelhouse there Captain but does the capstan increase pull force or just allow the rope to grip? I’ve seen those tree winches with capstans. They just create friction while the gear box creates power. Capstans on boats may be totally different. Sounds like you want increased pulling power from the quad. Hmnnn, top of my head two sheaves would double your pulling power albeit halving the pulling speed. Go faster!!!
I have seen tower companies rig a broadcast tower and use a capstan winch to haul loads. Not real heavy loads but enough to get the job done.
Capstans do not increase pulling power, no mechanical advantage. Biggest benefit is that it's a clutch-based system (my understanding of it) that will freely rotate in one direction, while applying a braking force if pulling force subsides. I also know that they have to be bi-directional, and I am completely unsure how that operates unless it is similar to a come-a-long.. in which you can change the direction of locking. This would require it to be a keyed drum type system. Not one with a simple clutch bearing to apply braking force. Once again.. without first hand knowledge, I am making certain assumptions from my knowledge base.
Yep. My ex father In law had a power company capstan winch to pull the dock into the ocean. I never even got to use it
Actually multi-loop pulleys are in "the wheelhouse". The mechanical advantage is more power over more time (distance). It is the simplest setup, but not necessarily with an easy way to anchor the load if you run out of real estate. Guaranteed there are multiple solutions, just haven't picked a favorite yet.
