FmC’s Hand mortar

(From Wikipedia)

“The hand mortar is a firearm that was used in the late 17th century and 18th century to throw fused grenades. The action was similar to a flintlock, matchlock, or wheellock firearm (depending on the date of production), but the barrel was short, usually less than 2 inches (5 cm) to 4 inches (10 cm) long (though some are reported to have barrels up to 13 inches (33 cm) long), and had a large bore to accommodate the grenade; usually between 2 and 2.5 inches (5 to 6 cm).”

I decided to go for a larger format this year - I knew I wanted to go MT-G2 with active cooling.

I’ve settled on a body style which I think is appropriate for this emitter, the Hand Mortar. The MT-G2, coupled with a big 100mm reflector, & plenty of Amps, will be able to ‘lob’ a big dollop of light wherever it’s pointed!

Here’s a glimpse of the ‘business end’ components that will be used;

Following the recent work that has been done with the diy-FET drivers, I really wanted to include one in this build, so I recently spent best part of a day wiring up a SOIC8 clip, installing the drivers & sw, modifying & flashing a driver, ready for a FET transplant.

Picture shows starting out with the SOIC wiring, to finally flashing the modded STAR firmware.

Hey, you got the same sub $5 multi meter I got!

Ahhh, but does it have the modded probe wires & repaired trace on the circuit board from trying to measure a little more amps than it can handle? :bigsmile:

Looking good. A small spacer that fits in the gap on the lens retainer will prevent it being distorted where the screw goes through. It could also be the start of a mount for a handle or it could just be left the way it is and I'll shut up.

I’ll be doing something with the joint on the bezel, I just don’t know what yet… I’ve filed it up a little since that shot to even both the tabs up.

going to be a cool shoulder-fired light when its completed

Looking good.

Thanks guys, bump for today’s progress….

So many more intricate parts that I want to do…… time will tell.

Very cool build. I almost used that same reflector from FT. It seems to be a pretty good reflector.

MRsDNF · June 9, 2014, 8:17pm

Good recovery. The timber work turned out nicely.

FmC · June 9, 2014, 8:58pm

It’s pretty thin, & mine came with a few small dings in it, but for a couple of bucks….

I used their ‘protective box’ shipping upgrade, as a few guys who tried to buy them ended up getting a squashed piece of alloy in their mailbox….

Tell me about it. I though mine was going to be simple. The devil, Murphy, Puck, and all their friends are hanging out in a club called “THE DETAILS”.

Bump for today’s work (end of post #4).

I like how people are incorporating wood into their builds, it gives flashlights, err… hand mortars, a whole new dimension. Keep it up, this is going to be a good one.

scottyhazzard · June 14, 2014, 5:12pm

Cool, I really dig this build. Looking forward to more.

Rufusbduck · June 14, 2014, 7:24pm

Nicely done with the battery holder.

MRsDNF · June 14, 2014, 9:29pm

Nice recovery. I thought l'd seen it all but no, modified Phillips heads. What Phillips heads.

FmC · June 14, 2014, 9:38pm

Sunday morning, off to work I go……

Bump for today’s work in post #5

Not a lot to see for today’s efforts (apart from the TEST FIRE!!)

A lot of time wasted re-wiring the battery pack & re-doing the end plate again, but better than frying the emitter….

MRsDNF · June 15, 2014, 10:18am

I'd love to see a dozen members on this forum build a joint effort light using basic tools. I could not imagine what the end product(s) would look or work like. Nice comeback with the wiring.
