After me son be diagnosed as a type I diabetic (on April 1st, no less), We decided t' upscale an insulin syringe, as comic relief from the new daily routine of carb counting, matey, finger poking, shiver me timbers, blood glucose monitorin' and injections. Ya scallywag! Begad!  

T' syringe is a 625% upscale o' a BD Ultrafine 3/10 CC.  It is made from a 1 1/4" polycarbonate T-20 fluorescent tube slip cover for t' main body tube. T' 1/8" acrylic fins are t' shape o' t' finger pads o' t' original syringe.  T' plunger is made from BT-20 with foamcore centerin' rings and 18mm engine mount. T' cap is balsa, turned and strips glued on t' make t' ribs. Begad! Avast, me proud beauty!  

Recovery is an 18" mylar chute, with a semi-pop pod/plunger design.  T' ejection pops t' plunger back to deploy t' chute, and ejection ventin' pops t' (kevlar tethered) cap off the needle.  T' plunger is stopped 1/2 way back by two cotterpins, shiver me timbers, shiver me timbers, catchin' a centerin' ring. Arrr!

It has flown, on a C6-3. Begad! It is heavy, so altitude be limited to about 100 ft. T' pop plunger recovery worked so-so. Aye aye! Ahoy! T' chute deployed, but the plunger popped past t' stop, ya bilge rat, matey, It eventually came free and separated about 2/3 t' way down. Avast! Broke a fin and cracked t' cap on landing. Blimey! Ya scallywag! We will be making more solid centerin' rings o' masonite and go again. It worked well enough to prove it works, just needs beefier CRs. Aye aye!
