Have you ever seen a Channel Locks 2 or 3 mm thick? He obviously has a special needs situation. I have ground down cheap wrenches for that need but not down to that thin dimension.
Not anymore. The part that requires this size wrench has not been made in 60 years. The largest size available these days is 32 mm. The people who have the larger size versions hold on to them because there are no replacements available.
If I want it made I'll just give the specs to a machinist at work. I'd rather make the tool myself, though.
Probably not that hard to do with a drill press and a set of files. Mark the stock, drill small holes, cut carefully with the appropriate blade, file to an accurate fit. Then cut the tool out from the sheet stock once satisfied.
That's my plan. Drill holes in the corners. Use a jeweler's saw followed by small files. Just wondering if there was a better plan. I'd hate to spend more than an hour on this.
For a watch back go to Esslinger.It's for an unusual watch back. I can use a case opener with the kind of Jaxa bits shown in the picture but it's a little risky. A ring wrench is much less likely to slip and scratch the case back. And no, the sticky rubber ball does not always work. 12 and 15-sided ring spanners are available in a variety of sizes, ten-sided ones not so much.
10-sided is not available in larger than 32 mm. Esslinger and Otto Frei are where I buy my watch tools, parts,, and supplies. 10-sided is rare to begin with (Panerai and some Chinese brands, I think).
