Bit of cutting / edge grinding and pot now fits into bin - sitting OK on top of internal lip.   Need some vermiculite now to fill outside gap between pot and bin  then all set to go.

Pics to follow

Edge ring done with gap left for air entry to charcoal area. 1st snag hit - bin isn't uniformly round at opposite  seams - so need to either grind off some of the pot edges to make fit or cut down a bit to give less radius.

Manchester branch now open and excellent reviews already in local papers - so they are keeping up the tradition of good quality food as per Cheadle original.

Well worth a visit guys if you're in Manchester.  Be sure to book.  opens at 5 pm Closed Mondays

100mm deep base put in using lwt agg mix with heat resistant white alumina SECAR 71 cement.  Leaving to set before putting a similar mix as a 50mm deep ring around edge to sit clay pot on.  May do this tomorrow if base is hard.

I am well aware I am veering off the line of Jimmys build - but using my concrete technology knowledge, with access to materials Joe Punter would not normally come across, I am confident that by using a special cement with high temp resistance as used in foundry / furnace work (1000 deg C +) and lightweight sintered aggregates in the mix for insulation - this should stand up to the rigours of tandoori work temps.  The internal pot is clay fired type - so this should withstand heat.  I will surround it with another lightweight agg mix similar to base mix - but this time foamed for additional insulation properties.

Being inside a zinc coated steel bin with lid - it will be covered at all times - so water ingress should not be a problem.

I will of course let the whole thing dry out for quite some time before firing it up.

Here's hoping my technology theory works - if not, I can always strip it out and replicate Jimmys firebrick route.

Just ordered the dearest bit of the lot - 5x Im long stainless square tandoori skewers from Spice Kitchen - ?35 (10% discount offer on at mo)

Cut the top off my large flower pot using a diamond tipped tile saw (not having an angle grinder).  Will use a lightweight concrete aggregate for the insulation base using high alumina heat resistant cement - and maybe same for the insulating pot surround within the bin. That's the beauty of being a construction chemicals specialist - I have such stuff to hand foc - collected as and when in my work.  Will use a drill to make side entry hole for air flow.

Got my bin (90L - ?16 off ebay) & large flower pot (spare from garden)- making mine shortly.

Use it for my Sriracha honey chicken wings posted on here.

Also made my own version when I had none.

** the exact recipe I used to make my own instant 1/4 cup Sriracha version for use in the main recipe as below :-
.
15x home grown 1" dried chillies (super chillies 50k scoville rating) - you will have to determine what quantity to use for 'other size /type chillies' if you are making your own version.
1 garlic clove
1/6 th teaspoon salt
Splash of vinegar
1/2 tablespoon sugar
1 tablespoon water
Place all the ingredients in the Revel blender and mix until a smooth paste.
Use this as the Sriracha ingredient in the melt butter bit etc. bit in the recipe for the Honey Sriracha Chicken Wings recipe below.
It was used within 2 hours of making it all up.
After putting the BBQ'd chicken bits with the butter etc. / Sriracha blend and basting, the chicken bits were put back on the BBQ to finish off a bit more and 'dry' up the sauce on a bit more on the chicken bits.

bug spray done for 2x more.

Now down to 2x plants !!  My fingers not as green as I thought.  Maybe that's why they sell you 10x seeds
