Bjorn's 3 Point Bumperless Esoteric - Finished

Here is one of two Cousin Cues Designed by Chris (Chirppa).

Chris designed these cues based on a nature theme from his writings.

Tropical Rosewood and Curly Maple

12.75 mm shafts

Bumper less with extension quick cam release

EE Wrap from Martin

Beau's beautiful veneers including white

Jump Cue with G10 ferrule tip. ( the jump cue is actually for Chris but I took pics with this cue )

The extension is finished Juma and this is a special cam action quick connect system. I modified this connection so that it fits in my standard 1/2" 13 tpi weight bolt pocket. The bumper is solid Juma instead of rubber for the bumper less feel Chris likes, but the system can be removed in seconds and replaced with a regular bumper and up to 1.5 oz can be added. The Juma bumper and machined brass mating system is 1.2 oz.

Here are some progress pics of the cue's construction taken with my I Phone in the shop:

Thanks for looking,

Great work as usual Rick. Will be fun to try them out.
I think you need to explain the 3 point design a bit better for those who is interested.

I will meet up with the guys (Stefan´s cues) when they arrive and I will write more afterwords.

Take care

Chris,

Your request was for a very very wide three point geometry and that request created a v groove pocket that was so wide it went way past the centerline of the cue at the bottom of the point stock. Way past. The amount of wood that was left in the sacrificial area was very scary and my first attempt failed as you know. On five test blanks, I backed off a touch with the depth of the geometry of the V groove and these two cues were the result. I now have the number on my mill table micrometer to recreate this interesting look any time I want now, so it was worth the effort. Stefan's cue is the other one and I will post the cousin today also.

On the first attempt I pushed the envelope too much and had a failure that would not structurally stay together during the taper turn that cut out the points to allow a collet on the taper for A Joint tenon stepping and facing. I had to make the forearm 13" instead of 12 so I was able to have a stepped tenon capturing 1" of the forearm wood with the machined short section. The exterior of the cue's forearm is 12" though after the procedure.

After turning the cue to the initial taper I had to bolster the joinery in that area by machining a stepped short and separate intermediate handle section to act as a integral strong back bridging this critical area and glue up with 12000psi epoxy. Essentially taking this weak area on this cue and making it super strong with mechanics and high strength epoxy in that short intermediate section of the handle.

So you can say this geometry request was quite interesting and I learned a great deal by addressing the request. Because of the overlay veneer gun sights between the points, it is hard to visualize just how just how wide these point are. People are use to visualizing the gap between the points in four or five pointers. Three is an all together different animal to reveal a small gap between the veneers on a three point deal.

Thanks for your design and collaboration on all 5 of these cues. As cue nerds we both have some fun!

Chris, It would be cool for you to briefly explain the thoughts behind these cues as the inspiration.

Here is a pic of the intermediate section on the handle. I searched the progress pics and did not find a pic that shows the special 3 wide point joinery so I had to describe it above instead.
