It makes for a highly entertaining day.

Yea its a good time. It can lob a concrete filled coke can (about 2 pounds) about 300 yards with 200 grains of black powder. I'm slowly scaling up the charge. I put together this little video of it being fired last time I went out. You can skip ahead a bit and not listen to me talk to just see it fired

This is no where near the size of a car battery. There's more than one way to skin a cat. I could do it with a lessor battery, but I have this as an extra battery for my motorcycle, and its rechargeable. I'm not hiking with this all day. Its basically just taking it from the car and walking 30 yards out into a field.

Oh, and sorry.... the battery is to fire a replica Civil War Mortar that I built. After I built it, I was reading the fine details of the regulations where I planned to fire it. I caught that there is a prohibition against anything fired by lighting a fuse. (I assume that is to prohibit people lighting fireworks.) So I reworked it, and modified model rocket igniters to fire it. Using battery power is definitely an anachronism, but ....Need to stay legal. I want to make this, so the aesthetic, at least visually, goes with the era.

standard sized motorcycle battery. Its about 7.5 lbs. That's a good idea. Adding a couple rivets or screw posts would probably make it bullet proof. Cool, thanks!

Thanks chuck, that's basically how I was going to approach the construction. One long rectangle to loop around the battery, and then sew the sides in place. appreciate it.

yea, its a modern sealed battery. - That sounds like the right direction. I'll work it up with 2 bands going around it, and the carry strap looping under and going through the two perpendicular bands. Glad I didn't try to make it without the extra support. - Thanks for the suggestions

Its about 7.5lbs which is 3.4 Kg. I was planning on sealing the leather good, and also putting some sort of plastic bag/liner around the battery for a little extra protection. I always wax my thread, but putting a little extra on the interior seams wouldn't be a bad idea either. I'll work the design using some reinforcing straps. The shoulder pad isn't a bad Idea either, although I'm not really planning on toting it around any great distance. I appreciate the suggestions. thanks.

Working on an odd project. I'm gonna make a leather case to carry a motorcycle battery, with a shoulder strap. I'm picturing the aesthetic of a civil war era cartridge box. I'm planning on using 9-10oz leather. Its a fair amount of weight. Do you think I need to reinforce it with a strap going underneath? I'm a little concerned about stressing the seams over time, if its not reinforced.

I'm only a hobbist, and I'm not selling what I make. However if I, as a consumer, find something I would like to buy and I ask, How much is it?.... If I don't get a straight answer, with a price, I'm done. No one likes to be jerked around. I don't see a problem with adding context of what work went in to making the good, but there needs to be a direct answer with the real price. --One guys opinion.

Looks like you've been busy. You do beautiful work.

man, that's clean. sharp looking holster.

This won't fix the problem after the fact.... But, before I cut leather, I make a test fit using craft foam. A sheet of craft foam is only about a buck a sheet. Craft foam folds and bends much more similar to leather and gives you a far better idea how its gonna work, as opposed to trying to wrap a paper pattern around something.

Ooo, yea, finding press in tubes won't be easy. In fact those probably were not designed to be replaced, which is why it took so much effort to get them out.

+1 ATF fluid and acetone is my go to for frozen parts. I normally soak it for a day or two. Then, I tap the parts with a small ball peen hammer. Then, I hit it with heat. Then, I take a can of compressed air, turn it upside down, and freeze it with the freon from the can. (expansion and contraction.) Then, I try to turn it. If it doesn't turn, it goes back in the bath, and I try it again the next day.

That's a good looking holster!

I like the cobra commander logo

That's really cool! Looks great

that's gonna look cool! can't wait to see the finished product.

That's cool. Good job working out the process. The final product looks great!

Good looking holster. Love those leaves.

+1. The electricity and filament costs would be minimal. The challenge will be finding ready made files available for "free" download with accurate dimensions. The file is only as good as the skill of whoever wrote it. Blue gun files are out there, but there is no guarantee as to the level of their accuracy, and there's no guarantee there's a ready made file for every model of gun you would need, just sitting out there for download. You would probably need to spend time to learn to use a CAD program to be able to create your own file .... or tweak an existing file to ensure its within proper spec. That's certainly a worthy skill to have, but you would need to determine how much time and effort you are willing to put towards it.

good looking handles! Gave that bag a well extended life.

Gotcha, Thanks Hags!

I keep a box of firebricks for when I need to heat up steel. Heat dissipates quick and it can be hard to get steel hot enough. I just stack the bricks to make small enclosed insulated space just big enough to hold whatever I'm working on, and it helps retain heat. - Might be helpful to get that stainless steel hot enough.
