After waiting almost 8 months I finally picked up my Weatherby Mk.V Accumark 6.5-300WbyMag. Being a quality rifle that's capable of some long range work I invested the time into bedding the base and lapping the rings over the long weekend. Thought I'd take a few pictures with the view that it might be helpful to others.
Prior to lapping I test fitted the rings to the base and using the lapping bar torqued the rings to the base (70 in/lbs). Removed the bar and moved onto the lapping process.
I then used "Painters" masking tape to keep the paste out of the action. Better to use too much tape then too little cause you don't want the paste getting into anything. Just a couple dabs of paste on the rings before going to work with the bar using a forward back, left right action whilst applying light pressure.
Once the bottoms were around 80%, I removed the bar, cleaned up the paste,
I put a few drops of oil on the bottom rings and a few dabs of paste on the top caps. I screw them down with just enough pressure that I can move the lapping bar.
At this point I mark the rings for position / orientation. As the bar becomes loose due to materiel being removed I nip the screws up a fraction working in a figure 8 pattern to ensure even pressure whilst also keeping the gap either side as even as possible. Some of the paste will make its way into the bottom half which is desirable as it'll finish them off.
All done with 95% coverage and still enough gap either side to torque down to 35 in/lbs.
The critical thing to be aware of is not to remove too much materiel or there won't be enough bite in the rings to secure the scope under recoil.
All done and ready for the scope to be mounted....tomorrow night.
