When I really started to look at how to build the mini GF like the forum does, not trying to make my first box/idea work, it seemed so much better.

Although 16ga skin may be called for, some have opted for 14ga to skin the boxes. Me too. Better to weld .035" fluxcore.

I've decided for 2" sq tube. 1/4 may be really good but 20ft is 109#, 3/16 is 87#...22# difference.



What thickness do you think is best?



Starting by building fireboxes, is ashtray OK out of 1/4"... thinking it is because you put a tray in there too, so the tray would burn up instead of the structure.

3/16 is more than plenty for your tube steal.

1/4 for your ash pan is overkill in my opinion. It isn't subject to heat that would require anything more that what you use for your skins...I would use scrap from them to make it.

Hi
Tackling .5" plate cuts with plasma torch, think I like gas better

Those who have built and are using Gravity Feed smokers, as you look at how yours is holding up, would you make the firebox taller now to better survive the heat???

I have 3-5/16 above the burn window, close to plan. I'm hoping this lasts at least 10yrs. Being I have more .5" plate and other stuff, planning on cutting more for more fireboxes/GFs.




As a matter of hindsight, would you make your firebox taller to last longer?

Re: Stumps mini clone about regular size

Victor Cutmaster 42

At first using stock tips on .5" seemed tough cutting with 240v, then switched to tips with larger orifice, kind of like using a #2 with gas instead of a zero tip

Just in case anyone else has some similar issues. I'm gonna pierce with the junky worn out ones then switch to better tips for cutting. Hard to pierce but easy to cut.

Hi
I like to see all these interesting modifications that make things work better. Michael303 mod mini.

All they had at welding supply store was 60A tips? guess. Looked at box... 4200-SL60 OK so maybe that has something to do with why those tips work better. As with gas I like bigger tips but they use more gas, doesn't matter with plasma tho. So next time I need tips (tips?) wonder if they got 80 amp or 100 amp, they would work better?

I really don't understand amps in this regard because at 240v this just couldn't be pulling 60a unless the tip voltage is low and current is raised like in step-down transformers. Got curiosity up to see what voltage at tip is for cutting max setting on 240v.

Here's two GF furnaces finished, but, I see I forgot to weld bottom of one.

BBQ supply seems to favor the 1.5" insulation implying most of you are building your GFs using 1.5" and not 2" tubing, is 1.5" OK or what most are using?

It would be some cheaper and lighter

Some people can cut real nice or have the grill teeth machined.
I just couldn't cut neat enough with the plasma and it would be a pierce for each of the 9 windows thru half inch plate.

Later I figured a trick, line em up and drag the rod over them clamped with wood so each is held. All tacks done in about a minute. Best I could make this look using square stock.

Since this is not a bought plan for the furnace, just mine, and I did it some different, hoping to manage ash better, thought I'd post it and since I made many others that were not quite up to par or good. This one is scale and cutting the 3/16" for chute into even 24" leaves total height including some random both ends... 37" tall few inches to trim later... or make CC bigger

My plans are to make 3 racks having 6" space between using 3/4" angle for racks and make CC about 31" tall internal

For durability, I painted outside with that BBQ paint from home depot, should make furnace last 2x as long.

As expensive as Tel-Tru are, I'm going to only put them on the one I intend to keep and use, they're $58 at BBQ supply, but they sure look nice!

Working on furnaces, the 4th one here shows that different grill track, thought THIS time, to weld side plates and supports before installing the furnace bottom.
