Let's put it this way... The 1340GT is the lathe I should have purchased several years ago, due to the amount of threading and precision work I found myself in the midst of. It's an outstanding all-around general purpose unit and particularly well suited for gunsmith work.
When I purchased my 1236, a crazy series of events took place right at the time I was starting to do commercial work. I ordered a 1236 and it was several months due to arrive. The factory had an issue and delayed it one month. OK, that happens. It arrived on the ship just in time for a hurricane and the ship bobbed in the water for a week and finally got diverted from NY to CA taking an extra week. It got off the boat but, was unloaded by a different handler who lost all the customs paperwork -that took two weeks to resolve. While on the dock, there was a Union dock worker strike for two more weeks then it made it's way by train to PA -only to be met by another Union rail worker strike -causing another eight day delay.
I lost my first decent contract job but, such is life. I wasn't crazy about the customer anyhow. Matt offered to upgrade me to a 1340 at his cost but, in all honesty, I couldn't accept that as I honestly don't feel someone's livelihood should be given away because of a series of events that are not in his control.
I've been perfectly served by my 1236 but, the automatic gear change box sure would be nice. Still though, it cuts perfectly straight and I take cuts within a half-thou at will and with ease. It has never let me down or had a malfunction of any sort. I purchase steel for jobs 500 and 600 lbs at a time and furthermore, that lathe has cut more stainless steel boat shafts of various types than I can even guess at... I've probably threaded a hundred miles, one inch at a time... Inside bore, outside bore, left hand, right hand, double threads -most of it on stainless steel. The overall unit shows no signs of wear. The 1340 will do everything a 1236 can and then some...
