Hi all,
I have the chance to buy some 4 and 3 meter long tubes they are 4inch inner diameter with a wall thickness of 7mm.

They are extremely strong and I have the chance to buy 300 of them.

They are going to be fairly cheap for me to sell them as I am getting them at a low cost.

I was just wondering how many of you pyro-heads would be interested before I comit to buy them!

They would make wikid mortars or mines....I am going to make a nice new ball mill out of a section.

I will not post them in 4 meter lengths but will custom cut them to any size for anyone who wants them.

There will be shipping cost on top of that but I will do my best for a low price....Free shipping available for larger quantities.

Maximum size for royal mail is 1.48 meters and 2.5 meters for DHL

They are quite heavy and extremely strong.

So as I said I need to know tonight or early tomorrow morning if you are interested and how many you would like!

If you want more details please reply or PM me.
And just reply if you are interested!

All the best
Rob

You may have a cheap deal BUT have you ever fired shells from these tubes? 7mm wall seems thin to me for a 4" mortar and mortar failure is always a very bad incident. If you are absolutely confident in these tubes with practical supporting evidence then consider the price of a GRP mortar and consider the price of getting a plug fitted in your card tubes.
Pour some polyester resin and some warm dry sand in equal quantity down the tube to make a plug say 1.5 inches thick to make a few trial plugged mortars.

I do have a supplier of cut wooden plugs to precise measure if you decide that it is worth getting a run of 100+ plugs made, the supplier is in east London.

I do not deal in 4" aerial shells, The maximum I do for now is 2" as I have just started out on the hobby!

I have no way of testing these tubes. All I know is that I can stand on them and they do not compress at all and I way 9 stone so they are pretty strong!

I have no idea if they are suitable for mortars im just suggesting a use for them.

If the buyer is happy using them or has previously used them as mortars then I am more than happy to sell them as mortars.

If I was going to use them myself then I would be very confiident using them as mortars but that is just me!

Either way if people want them I will get them if not then I wont!

Anyway mate thanks for your input, much appreciated!

As a comparason, the spec of Essex tubes 4 inch mortars is 101.6 mm x l2 mm x 6lO mm - a year or two ago they were about 3 quid or so each.

Ok lets not talk about uses of the tubes....Does anyone want them or not? I need to know today or they are going to get taken away by my friend who I will be getting them off!
