View Full Version : What Steel cable should I use?

I finally got a manual for my Enco surface grinder. The table traverse is driven by a steel cable that is wrapped @7 times over a 1.5" (38mm) capstan . I have none of the original cable. The Chinglish manual says the replacement is a 3x19x3x6m cable. I am trying to figure out a suitable alternative. I presume that the 3x19 indicates the cable form and the 6m indicates 6 meters (although 6 meters seems excessively long). I have no idea what the 3 indicates. The capstan grooves look like they will take a max of 5/32" (4mm) diameter cable. So it looks like I will need a very flexible cable. The table weighs over 150 lbs, so I am going to need some strength although it floats on 47 five eighths balls.
Does anyone have any suggestions on what cable I should use and where I might get it??

TIA
Randy

The McMaster-Carr catalog www.mcmaster.com has quite a good writeup on the various types of steel cable.
See for example www.mcmaster.com/#about-wire-rope/=1oua6p

I re-did the cables on a couple Kent 6x18 grinders.They both used 3/32" braided stainless which actually measured .135" OD.

Got it from McMaster.

I second (and third) Marks suggestion on Stainless and Wierds on braided Stainless. Similar wrap around system on a hand adjusted double headed mitre cutting saw used in plastic window making industry.

Thanks for the responses Guys.

I like the idea of the stainless braided cable, but I can't find any on the McMaster site. In fact a Google search for braided Stainless steel cable turns up motorcycle cable and jewelry. I an not sure what this braided cable looks like. Is there possibly an other term I should search under?

I presume I should be looking for uncoated cable?

Thanks Again

Check out your local Ace / True Value hardware store. They should have something to fill the bill, sold by the foot. Isn't garage door cable about that size?

Try West Marine for stainless wire. Used in sailboat rigging, life lines etc.

Good luck,

Rick

IME 1.5" dia is a bit small for ordinary rigging type wire, suggest you look at wire fishing leader, super flexible compared to rigging wire......... also in nylon covered.

Thanks Rick,

Being and old sailor any excuse to venture into West Marine is always appreciated. I found some very flexible cable that ought to work fine. Of course West Marine liked it a lot too. (a buck seventy nine a foot). It does fit the capstan well and now I am off to the next opportunity, the magnetic chuck. I started a new thread for that.

Many thanks to everyone for their input.
