Lewis winch : gear reduction

Anyone here tried their hand at making something like a Lewis chainsaw winch ?

I've got a spare Husky 36 that would be a good candidate for this...

Curious to see pics / designs, and hear what gear reduction you used.

Have you seen this one?

I use a 4stroke water blaster motor with a “mate” post hole borer gearbox on it, the 25mm shaft easily accepts a Capstan drum

Nice and quiet and easily snaps 500kg sash cord at just above idle

It’s lifted many a deer 700m back up to the road. I have 3x rolls of cord at 250m per roll

Very economical and quiet

A big thankyou to BRADS for the gearbox

Found this on YouTube last night.

Very clever - guys grafts a 1:31 worm gear onto a small chainsaw motor.

quite a few NZ jetboat guys are setting up little capstan winches. Worth a google

Yeah you could really tell when you had a good load on, the rope would start to sea saw.

I'm using this for my jetboat.

Might be worth seeing if you can replicate any specs? Or just copy 7mmsaums as that looks ideal

About 5 years back there was a Nz made one that bolted to a saw .It was a lot better made than what is available now.From memory it had a 3 ton single line pull.I can't find any links to it now pretty sure it was on trademe for a bit around that time.

The problem with running a winch off a chainsaw is the bloody noise, screaming away for ages while your trying to get a job done

4 stroke power is just so much quieter and more comfortable for everyone involved

Interesting.... Not much more than you can move by hand with a couple of pulleys though, a lot less hard work and rope cutting into your hands

Theres a local guy selling those old "mate" borer heads now all reconditioned and can made to fit any power head if you no anyone after one.

I have a pcw5000 and have picked up a lewis winch with a big saw engine off the ground and surprisingly it was no lighter but included the cable. If the mate gearbox proves sturdy long-term then 7mmsaums design is a winner. The going rate for a 2nd hand capstan pcw or simpson is 1.5k+ and they get snapped up fairly quick, Jet boat guys are looking to buy these new at the moment but there is supposedly no stock in the country.

If anyone has a simple design for a sturdy lightweight land anchor I'd be interested to see

I have used a lot of Waratahs as land anchors

Drive them in full length with a D shackle on the top of them

Cheap easy and effective

This is the most simple solution I've come across. Have tried the anchor type but are hard work in rover

Cheers found this link https://www.facebook.com/WattsCraftN...1374387612588/ you reckon that is thin dyneema they are using? I have 100m of braided 14mm rope and it has some weight and takes up a bit of space.

14mm is way to thick. I have 10mm and even that is probably overkill

3 warratarhs inline linked together is enough anckor in most terrain to recover anything or stall any common 4wd winch .

The best ground anchor I have found is my Defender for the Hilux's to get through @MSL

Your point? Still best anchor.

That may have been the one built by a good mate of mine, I think he sold them as the "Salmon Winch". Had a really nice cast alloy housing with the drum out front and and it bolted to either a Stihl 66 or 88 Magnum powerhead... I can't remember which. Yeah he had em on TM for a while and short vids on Youtube of pulling logs and boulders around a paddock. Did a quick search but can't find any reference to it now sadly.

We have another thread on the original winch I made and I still have this one in the shed as well

I kept the Tecumesh 2 stroke on it and apart from being loud it’s still powerful.

The main issue there is, the defender can’t make it far enough to be used as a ground anchor for the hilux. Ground anchor is no use if it’s stuck with three wheels still on the sealed road

Salmon winch that was the one.You dont have any contact details for him?

Never caught up with what happened to that, it was probably very spendy but what a design - I still can't find anything equivalent commercially.

Is that the unit used to tighten the turn buckle chains on the log ships, they are a nice unit, 12 volt Makita drill, modified thru, I don’t know how many ratios.
