roach with your welds take a look at my link please could help you out much better

as goes for welds a nice ground down does help

i like the idea of both wood and pellets

I sux at welding also and I'll be cleaning up my welds with a grind before finish coat as gadily stated " for welds a nice ground down does help ".  You should have seen my first 2 cuts with the plasma cutter....I should have practiced before I started cutting with it!!
It really helps to have the metal clean before mig welding, which I don't always do.

i was having a problem with wire feed is not was not right it stops in the middle of welding it was pissing me off what can you expect from harbor freight welder

these are the usual causes for wire mig feeding

take a look at your inner cable as this wears down it jams the wire as your welding

also another subject is check your swan neck on mig after this problem consider your motor at fault

i did not grind anything most of the weld were ok i started to having problems with the wire speed it just stops just for a second i just wanted to get this finshed it was good for first build i will take more time on the next one

there is changes i would make on the next one the feed tube at 22 degrees to keep it away from the tank it is a new harbor freight flux core 170 i tried to adjust the drive tension i will check it later also make sraighter cuts take more time kepp in mind i was working in the driveway no shop to work in it sucks

Roach, What's the rectangle piece of metal that's welded to the front of your tank between the tank and the feed box?

that is my heat sink it is full of perlite stuffed in there keeps the temp to where my pellets dont get to hot i have it running now it is putting out alot of heat this went into the house the pipe went into the fireplace flue

OK. I kept looking at it thinking it was something for pulling hot air for an intake or something.

Do you have a video of it fired up and running?

not yet i started it up this morning it took one minute to take off no smoke comming out of vent

just had a problem with draft in my stove i found ash in the elbow of the exhaust enough to not draft up the pipe if someone puts one these in make sure to have a cleanout on the exit of your tank and on the elbow of your exhaust just found this so keep this in mind it smoked my house out no damage still stinks it will go away soon

thanks for your info roach

the system is that small it will put ash inside of the exhaust pipe its same with the dyno v system

also watch out for this with pellets

ok just tried a new basket with a 2 inch hole in the bottom it works but not as much heat at the top of tank and i got no smoke out the exhaust on the old the old basket i was getting lots of heat and sometimes black smoke out of exhaust pulled the fuel lid back one inch and got still lot of heat and no smoke i will try a vent thru the fuel lid to the combustion chamber that should fix the problem i hope thanks guys and made a tee with a cleanout it seems to work good for the exhaust
