This chamfer and drill jig is manufactured from a recycled aluminum connecting rod. It will allow you to drill the bearing for a rod pin or chuck it up in a lathe and chamfer your bearings.
A common rod pin size is .180 with a .1875 drill being used for the bearing. If the bearing is perfectly centered, the clearance between the two is .00375. I found through checking numerous sets of rods from various manufacturers the pin location varied up to .005. In these cases the pin would “bias” the location of the bearing rather than locating on the bearing tang as intended. To correct for this possibility I have installed a #10 drill bushing (.1935) in the jig. If your rods utilize pins that are less than .180, let me know what size you have and I will supply the appropriate size drill bushing and drill.
Note: If you need a jig for ANY rod, I can accommodate. Give me a call.
All jigs come with complete instructions included along with drill and storage box.
P/N RBANYD Drill Jig only for any connecting rod. $179 + shipping *
P/N RBANYDC Drill & Chamfer Jig for any connecting rod. $239 + shipping *
This will require sending (2) connecting rods and a set of bearings you will be using.
One “donor” rod to cut up and a second to check the new drilled hole for accuracy.
If possible, the “donor” rod should be of the same brand you will be using.
If you have a bearing, new or used, with a factory installed pin hole, send it along also.
It’s good to check all possibilities.
