Width of double 100's

[Akimbo]

I'll have to give that a whirl come VIP time.

I used UHMWPE but Nylon is also a good choice. Plastic cutting boards would work if you don't have a commercial plastics supplier nearby.

The challenge is cutting the blocks accurately enough (width and parallel). Woodworking machinery (not hand held) like table saws, chop saws, and router tables can do the job with the right fixtures. These parts are small so can be very dangerous to work with. Of course it can be done with woodworking hand tools if you have those skills.

Might be wrong location....

But I'm building a tank drying rack and need to know the max width of double steel 100's.

FN,

Without tank boots,

3.625" + 3.625" + 8" = 15.25"

For ease of getting into and out of rack, 16".

Where is the inches from. The valves don't go past the tanks.

Unassembled I get 7.25+7.25 (tank diameters) + 2 for the space in the bands so 16.5 + boots

I have 3/4" UHMWPE sheets that have a pile of circles cut out of them, but with sufficient remaining area at the ends (former clamping area) to use for this purpose.
They'll get cut out on my CNC mill, so "accurate" just comes down to preventing garbage-in .

With this, I guess there really is no "standard" for size as actual tank diameter becomes the critical variable.

Really,

8' center to center, and half the diameter of the cylinder on each side of the 8'', or 8''+ 7.25'' = 15.25

My two sets of double HP steel 80s are 7.25'' each, with 8'' center to center manifold, outside tank to outside tank is 15.25.

Good to know thanks.

The standard isolation manifold's center-to-center distance is 215 mm (8.46”) +/- 5 mm (0.2”), not 8". See Isolation PRO Manifold — XS Scuba - Everything For The Perfect Dive

Good to know thanks.

FN,

Some manifolds are slightly different.

My Thermo manifold and OMS bands are set at 8'' center to center. depending on band selection, and age of bands selected, you may be able to adjust up to 8.5'' center to center, although with 8.5'' center to center, you haven't captured much thread on your isolator valve.

Neither of my sets are showing exposed threads on the isolator valve, which is canted in slightly.

My sets do not have boots.

Best,

Rose.

Both XS-Scuba and Thermo specify 215mm centers. Thermo makes a narrower isolation valve for 190mm centers or 7.48031". Both make up to +/- 5 mm or 0.2". These dimension are consistent with manifolds in my shop that I measured with digital and dial calipers.
