The rear grip

I found this with the replacement mower parts at a local DIY retailer (also check mower dealer/repair shops). It's a Briggs and Stratton "universal pinion gear" part no. 5086 (on the back of the package it's 5086D, and says "same as 695708"). While it is about the right diameter, unfortunately it's only about 10mm thick. With a bit modification to fit them together, a stack of four should do the trick.

Here's the assembled but unpainted gear. It took alot more grinding and puttying than I originally thought it would.

Initial Assembly

Here I've connected the grenade and gear/booster/rear grip with a spacer, once I removed the dowel screw from the grenade. I've also extended the broken neck with a short length of 1/2" CPVC.

Initially I was going to discard the solid windvane in favor of a hand fabricated version, but soon thought better, I ground out the material between the outer sleeve and the core that screws onto the neck, then relpaced it with "fins" made from plastic "L" track.

Here's a view from the other end, with the hand made emitter in place. It's painted with a richer shade of silver paint from plasti-kote (Pewter #159S). From this angle you can't see one of the emitter's most unusual fetaures.

Here's a view of the emitter showing it's unusual features. While the number of holes is incorrect, the ring is actually bevelled inward like the real sabre. That detail was made out of a wheel from a Tonka truck.Visible in the emitter's throat is the washer standing in for the "reflector" at it's base.

So much for the handmade emitter. When this machined pommel and emitter set became available, I decided to get them. Either that, or hand fabricate another pommel, something I was not looking forward to!

Here is the collected parts of sabre, modified to accept the new emitter, pommel, and the 3/8" threaded rod that connects them. The end of the grenade's neck that was broken off when I received it was broken off again. It will be replaced by the white piece in the middle.

Here's a preliminary assembly of the sabre. The clamp is from another sabre, and is only there for illustrative purposes. The calculator bubble strip will stay with this sabre though. While it has an incorrect NINE bubbles, it is REAL and not a resin reproduction.
