>408 watt motor
>20 amp hour battery 20*12=240watt. (Briefly, not actually for an hour.)
>50W peak output.

290w of power at your peak solar and peak battery, and that falls off to almost nothing after the battery is dead. That's not even full power of your 408 watt motor. You won't be able to charge and move with it, you could spend 4 hours in peak sun charging the battery, and then get an hour of movement at half power.

its a 20AH battery; it can run at 240W actually for an hour

Yep. Need to be replaced asap. Just solder a new batterie between the joints. Also clean the pcb with Isopropyl alcohol (also asap).

Are there any good documentaries or TV shows or anything that can actually teach you about tools and how to make things?

I'm starting to get into DIY as a hobby but I am still a huge novice and im just trying to absorb as much through osmosis as possible. I usually sit and watch a tv for 20 minutes every morning as I shovel food into my face and drink coffee. Might as well try to learn something while I do.

Ever heard of "how it's made?" It was a short lived show about how different things are made. Kyaks, guns, cd-roms, cheese, candy, tires, toilets, etc.

I think there were only 20 seasons or so.

hey /diy/, I'm making a guitar from a kit I bought and I thought it would be cool to do a lichtenberg figure on it. The process involves coating the outside with a mixture of water and baking soda and I was wondering how long I should wait for it to dry before I start staining and poly coating it?

The wood is mahogany and I have no idea how long it will take to dry. I've had it sitting in front of a fan for about 2 days. I just don't want the stain to get fucked up or it to start warping from residual moisture later on, it did soak up a decent amount of...

You might consider throwing it in a trash bag with a container of damp rid. Just don't let any of the desiccant touch the wood, but sealing the guitar and the open container of damp rid in a bag for a day or two should dry it right out.

Is it hard to tailor and sew good fitting jeans?

Can I use lag screws to pull it closer together and cement to seal it? Not shown but there's another long screw connecting them.

Hard to tell but there's a wood "block" embedded in the cement that the original was drilled into. Tried kicking it back together and smacking it with a hammer.
>>
>>950166
you need to remember newtons laws, for every action there is an equal but opposite reaction.
therefore, since the damage was done by backing the car into it at an angle, the only option to fix it is to back you car into it at an opposite yet adjacent angel.
Since you altered the situation by kicking and hammering it you need to estimate the amount of change you created.
Id estimate it to be 5%, so my advice to you would be to back into it only 95% as hard as the first impact at the correct angle.

Whipping and pausing, I don't have much trouble in the flat position mainly just vertical and overhead.

On the vertical watch your rod tip-- keep it even - do not let it fingernail. Vertical is the toughest to get consistent at because of the lack of vision on the puddle. Pay attention to the sound your rod makes. As for overhead, it should be just like flat with 6010. Watch your heat.
