Over the last few days I've been working on a paying gig. These are drive and tail shafts for augers in an underground mining silo.
The job is for two simple shafts 24" long from 2 7/16" diameter 1045 with two holes 90 degrees apart. Also one 15" long with holes and a key-way. I purchased 66" of stock, that comes in at 88 lbs ... quite a struggle to get down the stairs to my tiny shop! I band sawed to length and cleaned up on my 1440 lathe.
Chatter was a huge problem when trying to face. This is one of the 24" shafts it comes in at 32 Lbs.
Next over to the mill/drill. I needed a way to index the holes 90 degrees apart, (my indexing plates only have a 2" capacity) so... I glued a v-block to the end. a v-block just for the nice square sides, it could have been a 123 block or anything with nice square edges. I glued the clamp to the table while I was at it.
This is the Bostik 260, this belonged to my father, I think it is seventies vintage. 110 watts, made in Canada. This is not a dollar store crafting gun. This unit takes about 10 minutes to warm up and causes the lights to dim when you first plug it in. Once warmed up it provides a warm aromatic humming aura to what ever corner of the shop its used in. Releasing the v-block or clamp is a matter of a light rap with a hammer and the item will release clean and the glue pulls off cleanly and easily.
The last shaft needed a 5/8 key way .355 deep. I nibbled at it .050 deep per pass. Even this light touch shivered the timbers of the Wrong-fu 40 square column mill/drill.
All in all a profitable and fun time in the shop. Thanks for looking
