Spirolox, TruArc's, whatever...
We're pondering over a small problem. My son's 383" kit cam with spirolox pin retainers (927-042-CL) and after wasting the better part of an hour and not getting a single one in (out of 32), decided to file-13 the darned things. JE lists a Truarc internal snap ring (927-042-CT), which Summit sells for $1.69 each! Our local Fastenal supply store has a similar snap ring ($0.19 each) that's ever-so-slightly larger (.938" OD vs .901" OD). JE's website shows their 927-042-CT part to range from 0.896" - 0.945" diameter, while these Fastenal pieces are 0.938". I'm thinking they'll work even better, as the tension will be a little more when in the groove. Thickness is the same.
Will they work?
