Torqueing of dry cell bolts

[bigjim56]

Does anyone here use a torque wrench for torquing their dry cell bolts? I want to be precise in the build, but a search for torque settings comes up empty. I'm using the pan liner for my gasket and lock washers backed by flats for securing.

I was just gonna go until the lock washer collapsed flat, but that doesn't seem as accurate as a torque wrench setting. I've over torqued many a bolts in my day, so its probably better that I use the torque wrench anyway.

Thanks,

To be honest with you, you're going to find that different end plate materials / thickness and gasket thickness / material is going to effect the kind of torque you're going to need for a good seal.

I would recommend that you simply tighten them in a crossover pattern, like the head of an engine block, a little at a time. Use a sink full of water and an air compressor or equivalent to check for leaks.

You will also find that some gaskets materials, like PVC, will require re-tightening after it has been through a few warm up / cool down cycles.

Russ,

I have 1/32 Neoprene coming in.

I should mention that after tightening, one can measure the total cell width and calculate the compressed gasket width.

I use my 19V Sears Drill/Driver, torque setting at #8(of 22).
Have no idea what the inch/pound or ft/lb would be, but it makes for a good seal and consistant bolt pressure on my 3/8" acrylic end plates.
