"O" Rings and Alternative Bottles

I have only used the Wamadet large and small bottles myself, The intermediate type is given merely for completeness sake.
Dimensions are in mm.
| Description | O ring ID | O ring OD | O ring Thickness | O ring Tol ± | Bottle ID | Groove OD | Groove Width | Plunger Dia |
|---|---|---|---|---|---|---|---|---|
| Wamadet Small Bottle | 10.77 | 16.00 | 2.62 | 0.08 | 11.1 | 15.98 | 2.60 | 10.8 |
| Intermediate Bottle | 12.37 | 17.6 | 2.62 | 0.09 | 12.8 | 17.58 | 2.60 | 12.4 |
| Wamadet Large Bottle | 13.94 | 19.18 | 2.62 | 0.10 | 14.4 | 19.09 | 2.60 | 13.9 |
The original bottles had only one "O" ring seal, but I recommend two, not for extra sealing, but for stabilization of the plunger in the bore. The top 50 mm of the bore should also be mirror polished. This is so that if accidental contact is made by the highly polished plunger (due to a badly aligned hammer blow) the damage to the plunger surface will be minimised. The grooves that accept the "O" rings should be 4 mm and 22 mm from the top of the bottle to the top of each groove. Two 6.35 mm holes are drilled along a diameter centred on a point 14 mm down from the top so that it is midway between the two "O" rings, these holes allow hydraulic fluid into the bottle before the plunger is fitted.
| Plunger to suit | Head OD | Head Height | Stem Dia | Stem Length | Lead Length |
|---|---|---|---|---|---|
| Wamadet Small Bottle | 18 | 12 | 10.8 | 41 | 2.5 |
| Intermediate Bottle | 19 | 12 | 12.4 | 41 | 3.0 |
| Wamadet Large Bottle | 20 | 12 | 13.9 | 41 | 3.5 |
If a Particular "O" ring does not provide a good enough seal, or is perhaps a little worn, then a strip of shim stock or thin plastic film can be installed behind the "O" ring in the outer periphery of the groove.
The exit holes that are bored to allow the primers to be expelled depend on the size of primer involved, in the case of the Wamadet large bottle this hole is 6.6 mm in diameter and in the small bottle it is 4.8 mm diameter.
