Sputnik Fixture – First full frame miters a success!

Still have some tweaking to do but blown away by how well the fixtures worked.  Got a little tube clean up and prep to do before fillet brazing.  Henry James Jig needs some dialing in as well.

Sputnik Jig Setup

Experimenting with slotting tubing for dropouts on Sheldon Horizontal Mill.  Vise allows pass through for stays and keeps various diameters centered on slotting saw.  For tapered tubes the vise can be tilted to compensate and a round wire on the top of vee block makes for rigid setup.

Sputnik main tube fixture on the old horizontal mill.

Another view of slotting setup.  Cut a bunch of straight 4130 to dial it in.

Initial setup in jig.  Got some more hours of cleanup and adjusting to do before brazing starts but happy with it so far.

Machined some vee grooves into some aluminum I had hanging around.  Will add drill bushings at some point but works GE for now.

After making a few modifications to the jig I have it setup on the tilting table.  Did a couple of practice cuts and all went smooth. 

Next up I will work on tube length, alignment and angles.

It has a lip screwed on to the base I need to remove…frozen/stripped screws.  EZ Out in my future.

Ordered assortment of t-nuts and such so should be able to attach this weekend.  Goal to have Bringhelli jig mount by end of weekend.
