I correct as many as I can while using my phone to post. Even those few that slipped through are extremely minor to what MANY posters normally put up and never bother to correct. So get over it.
I posted to see if someone has done this before. NOT asking for advise on what else to use. If people would actually read, and comprehend before posting a lot of feeling (theirs, not mine) would be saved.
I know a keg can be made longer since I've seen the results. Was looking to see if anyone had actually done it yet.
I would be more than happy to include references to a few of your 2nd grade teacher red correction pen posts for spelling errors more minor than the ones in your post I quoted.
I don't know what I have to 'get over'. If you don't like the favor returned, maybe you have something to 'get over'.
You included in your initial post that you are using it for a mash tun, and therefore got responses as to why it would not make a good mash tun. You also got several posts about time, expense, difficulties, etc. of attempting this. You chose, as usual, to dismiss all advice as unimportant and off topic, along with a bit of derision.
Maybe next time you request advice, just post what it is you want to do, and not why you want to do it. Your initial post in this case would then turn into- Can you weld two guaranteed to be slightly imperfect and different sized cylinders together?
You would then get the responses you are seeking which would be - Given enough time and money, yes.
If you include that these cylinders were 1000 soda pop cans you are planning on turning into a very tall MLT, you are sure to get responses regarding the application, even if you include that you really like the convoluted bottom of the pop can for MLT purposes.
This is a recurring theme of yours- request advice for your 'new' solution to a problem that has already been 'definitively' solved, then dismiss all advice regarding the vetted solution in favor of your own Rube Goldbergian one.
I know a keg can be made longer since I've seen the results. Was looking to see if anyone had actually done it yet.
Maybe you should read your own posts more carefully. You say you have already seen two kegs welded together, and then want to know if anyone has done it? Your request would actually make sense if you were truly open to advice that it isn't worth the time/effort, but, as mentioned before, your requests for advice/input are merely rhetorical. You appear hell bent on completing whatever project you dream up, regardless of feedback as to its feasibility.
