3D printed dies-speed/ Tach assembly

I next put the upper die ontop of the stack. 
threw it in the press and locked it down. 😃 

I had previously practiced removing the crimp ring on a couple damaged speedos years ago( sold for parts on ebay). Succesful crimp ring removal is the trickiest part of this project... take your time if you give it a try.

hammering the crimp ring in the lower die is actually enough to hold the speedo together sufficiently.  The press just guarantees the job. 
 if you don't have access to a press but can print the jig,  I recommend using it for assembly as it holds everything perfect. 
good luck and I hope this helped someone..... 😃 

I appreciate Your effort and You're on the correct tract! Might i add something pertaining to initial removal of that crimp ring? Ya really don't want to use your "modified" pliers to lever on the upper can. You can dent them easily. Your's was pretty rough initially but pressure might be better applied to a protective layer. I do all sorts of gauges and have made tools out of generic crap from the toolbox. That pipe shown is a notched-out Schedule 40 PVC 4" section, have been using it for over 10yrs. My clamp-back tool is an old      Kawasaki Z1 sprocket notched-out.    

I like that idea for the pliers to pull back the crimp rather than pushing from the lower can. I will have to make one similar. I like my idea to get it started but those pliers do a push pull rather than just a push on the ring.

I like how you repurposed the sprocket!

I also have a latheand considered using it but the 3D printer was easier and a 1 time job... this time. 😆 
 I CAD,ed up and printed a couple of test pieces with my 2 printers- took about 45 mins. Once I confirmed fitment, I had the printers work overnight while I 😴 slept. Parts were 6hts and 8hrs to print. I find myself using the 3D printed term for rapid prototyping all the time now.... and if it has to be Aluminum for the final product, then I use the mill or lathe. 😃 

That's some cool machined jig stuff H1V!! I don't own a lathe though and just gotta make do. AND..each instrument has different diameters so, i do this. Where diameter of gauge isn't an issue. No true Kawasaki enthusiast hasn't had a two-stroke S or H series laying around, ha. Pictures show why there are two notches cut out of the Z1 sprocket. One for Z1/KZ other for the Triples or Norton-Triumph-etc. As pictured, same sprocket works to remove and install without hitting the paint, on early 69-72 ones that don't have a shield. Maybe beyond the scope of topic but opens possibilities..
