Jts70 yes i fill it up tho i use chunks more then chips, I dont let the wood turn to ash in my GOSM Ive read that many times over the years its said to produce a bad taist i dont know how right that is but saving the black charcoaled wood can be used later as charcoal, i just dump out the pot and add more if i dont have another pot filled and ready to go.
you cant really use to many chips, dont pack the wood in just leave it loose but fill it up, when i use chunks ill put those in and then fill in the gaps with chips of a different wood.
