Great looking work Xmasguy, I see you’ve gotten the modification bug like a lot of us here have now... lol. Just a few tips and steps to follow as you get started with your SmokeDaddy Smoke Generator.
Read the owners/instructions manual completely...
I would increase the holes diameter on the bottom canister cap a little larger and add 4 more. This will help with increasing the airflow and also help promote a hotter burn.
Use a Chimney Starter and use Lump Charcoal. Never start your fire in the Canister. If you have experience running a Stick Burner properly, that will help greatly. A lot of people don’t know how to manage a fire properly, so Fire Management and Smoke Management is very important when operating these Smoke Generators. Wait til the Charcoals are hot and ready, then dump them into the canister. FYI. Lump Charcoal when ready will always produce TBS Smoke... Thin Blue Smoke... It’s when you add your Hardwood Chunks and Chips to the Coals will the production of TWS smoke start. Thick White Smoke... The TWS will clear on it own. FYI. Smoke Management... Some TWS is not bad, but definitely not for an entire bbq. Use a mixture/percentage of 60%-70% lump charcoal and fill the remainder with wood chunks and wood chips.
Crack/prop the lid on your grill by about 1/4 of a inch to help any excessive smoke at the start of your bbqs to escape. I’ve found it’s easier to refuel the canister while bbqing with wood chips.
When you do use the shutoff valve that I see you’ve added, prop open the top canister cap a little to allow some of the smoke to escape. If you don’t, the smoke inside the canister will have no where to go and it will smother the fire within the canister and you don’t want that to happen. I’m not sure of the type of valve you have installed, but a high temp, gas valve would be safer. I sanded that top canister cap a little where it fits into the canister to help it to be easier too be removed when hot. When the canister is hot, it’s super hard to remove the top canister cap.
A properly run and managed fire, will decrease the production of creosote. You will notice after using the SD Smoke Gen. Canister, that the interior of the canister will darken. That’s because of the heat being generated within the canister and any creosote that was produced, will remain in the canister and not travel out into the cooking chamber... Which is great, but now it will require you to have to clean the canister after every bbq. If you don’t, the smoke quality for future cooks will diminish. Keep the canister clean, manage the fire properly and you’ll have great smoke production and a great smoke flavor profile on your bbqs as well.
For cleaning, I use an SOS pad, and grill/oven cleaner at the same time. The interior and exterior of the canister will darken due to the heat being generated, this is normal... but you don’t want excessive buildup and creosote to accumulate on the interior of the canister.
Keep it hot and keep it clean and you’ll be able to enjoy great Hardwood Smoke from your Pellet Grill now. Good luck.

Thanks RCAlan, on the initial adventure I lit in the canister with pellets on the bottom and used my heat gun to start the fire, wood chips and chunks on top worker perfect. I did drill the holes out bigger as you suggested.
