Picked up the base today, sprocket, shaft and 2 pillow block bearings came out right at 300 lbs, add weight of vise and that should keep it from walking away if it lives outside. Just need to figure out how I'm going to press that shaft to one end, don't think it will fit my press, might have to call in a favor.

The bolt is now cleaned and ready to be machined, fits vise perfectly.

Did some checking on the spacing with pawl in locked position, it is just over 1", so the BL844 chain would be too small. Doubt I'll be doing any oilfield type work, most likely just a way to hold pipe while I weld or torch it, so yes plain roller is most likely more than adequate. I know there is some big roller chain in one of the trailers (bigger than grader chain), I'll take a look at it tomorrow and see if its even close.

What is next size up from BL844 or #80 chain?

Have you figured out what size chain your vise uses? I could send you one or two links of chain that I have if that would help.

Did some checking today and decided 100-2 chain should work, 1.185" would not fit thru gap and 1.150 would. Looked thru junk in the semi trailer and all I found was 60 and 80 series chain. I've got some work to do to get pedestal ready, should not take too long for the right chunk of chain to appear.

Measured the press last night, 28" between columns, measured sprocket and its right about 28" dia, might fit might not, will try in a few days when car is removed from in front of press.

Here is a picture of a chain on a fork lift I saw today. The large part of the links are 1" in dia, the chain is around 2" wide, and the pitch is 1 1/4".

With 1-1/4" pitch the height should be 1.188", if so that would work, how fast does material pass thru that yard? The yard I usually visit moves stuff thru pretty quickly, if I'm not standing there stuff gets shoved right into a pile and some times grappeld straight into truck headed to the rebar smelter. If UPS freight shows up early tomorrow I might drive over to another yard that gets lots of big iron and oilfield type stuff and see if they have any laying around.

It isn't in a scrap yard, it has been there at least 10 years. I have been thinking about trying to buy it from him to make a large fork lift out of it. It is just the mast with forks and cylinder. I don't think he would just sell the chain. It looks like it may be the size chain your vise uses.

Default Re: 4"-14" Monster Pipe Vise - What is missing?

I was real proud of myself for finding some big leaf chain (1.250" pitch) this morning, off a forklift so I snagged the bolt, and it even had a nice cast iron "thing" for the other end. Got to the shop this evening, stuck it in vise, and it slipped right out

I'm not sure I need, or even want heavier chain, as mentioned before I'm not doing oilfield work. Thinking about it my options are weld/braze build-up the shoe that engages the chain, modify the catch, or make a new catch. If I hold the toggle down the shoe will grab the chain, but there is about 3/8" between the catch and the pin that holds it, not sure that 3/8" dimension equates to same dimension where shoe engages the chain.

The H dimension on the leaf chain is 1.140", if it was roller chain it would be 1.188", but I don't think .048" is going to fix this.

Just a couple pics, first pic shows toggle all the way down, and shows the gap between catch and pin. Second pic shows the "thing" ( I don't know what else to call it) to terminate the chain. Between the bolt and thing, once installed no one will be able to remove the chain from vise without driving out a pin.

My other option is find some 120 series chain, or equivalent in leaf chain, and hope it fits.

Charlie, there is a machined (round) pin that the chain lays on, then shoe comes in from the top, and these are what pinches the narrow part of chain. If I move the toggle down with this chain it does pinch the chain at the narrow spot, of course it won't hold it because there is too much room between catch and the catch pin, if that makes any sense?

At this point, to use this chain, I think the easy and easily reversible option is to just make a new catch. I still need to get the base in press, so I still have some time to find some 120 series roller or equivalent leaf chain, question is can I find that with the bolt and another thing to terminate the chain

Any chance of a backside shim in the clamp? As to fastening bolt to chain that shouldn't be too big a problem. Chain is steel, bolt is steel. Just weld bolt to links. Not uncommon to weld things to chain links. Have seen homemade trenchers where cutting teeth were welded to link tops or side. Might take some experimentation. But you're a smart girl!

DalG,
Yup, that makes perfect sense.
So, in a perfect world, the radius of the valley in the chain link should match that of the pin that it lays on. Got it.

.

I did think about that, wish those chain charts showed those dimensions, but guess most applications don't use chain this way so nobody thought to include them. Reducing diameter of the pin the chain rests on will only increase the gap at the catch, so that is not really an option. Guess I'll look for some 1.5" pitch chain, but still uncertain if it would be roller or leaf style, and for some odd reason the leaf chain always has a smaller H dimension, and neither charts shows width of the narrow part of the dog bone.

But you already have a chain.....
It would be against the scrounger's code of ethics to go out and buy another one.

If 'twere me, I'd think about turning down the pin that the chain rests on, and welding an appropriate thickness shim to the shoe; the existing latch would fit, and the job could be finished with the parts already on hand. But I'm frugal and impatient...........

Did a little checking, matched a socket up to just a tad smaller than the lower pin (I can see it has a slightly reduced diameter in center, machined, not worn) and checked it against the chain, and its a good fit. So I think this chain will work just fine with a new latch, and it really should be a fairly simple to create part, and easily reversible should I ever find a larger chain, or if smaller chain does not work.

D Girl, I have an old tandem out of an Allis Chalmers grader. I could see if it has 120 chain in it and see what the dia is of the links. It would be roller chain.

Another big old forklift was drug into the yard this morning, it has BL120 chain, I got the lower links removed from the bolts, but could not get to the top (safely). They will most likely be torching it Monday, so I will be there early
