hello all ,i am a supervisor for drilco,(well now called smith services drilco group by some) came from morgan city louisianna,,and am now located in broussard louisianna.around laffayette.we use v bottom inserts to thread with. on 12" hollow spindle lehmanns.3 of them. air kick out and rapid traverse.we also have a mazak slant turn 450,mostly used to cut drill pipe,as drill pipe comes in larger quanitys than collars and heavy wate.if you have any questions on collars,pipe subs,etc, let me know .as for the hobb last one we used in mrgan city was about 83 or 4 the collar shop there was shut down and moved to laffayette,the pipe shop stayed a while,longer and are now located at port fourchon louisianna..we have been single point threading on lehmanns ever since.we have had the mazak,about 3 or 4 years now. hence the name mazak,sure was glad to see that machine as we were cutting pipe and collars,repair manufacture,turning build up joints prepping stub collars etc,and that machine lightened the load of cutting drill pipe as well.we for a time were the collar shop and the pipe shop. in a sense the lehmanns are the collar shop now and the mazak is the pipe shop.johnoder ,the drilco hand is still around.if i might ask,what did you do at drilco? i assume in houston? its great to meet you,as it seems not many have heard of drilco,much less have worked there. i train poeple,for the machine shop here and they know drilco,and only a few get the name drilco hand.
