So over lunch break I went home and was working on a chamfer program when, power cuts out and an outlet starts making a not so nice buzzing noise So no I'll be trying to fix the power to the garage after work
Not sure how well that will work without coolant. The one I used had a plastic tub that sat on the table. The unit had a pump in it that would suck the coolant out and return it to the machine. The electrodes are pretty much thin wall copper tube. The coolant is pumped through the center to cool electrode and flush out the hole.Thanks, learnt something new,
Looking good, the runout wont really matter much for the tool you are making.Too cheap to buy a Rabaconda ( sorry MVI 😔) so decided to build my own version. Machined up the main spindle. It's has 24mm, 22mm and 20mm steps. The main spindle was going to be 18mm, but my Yamaha has a 17mm front axle, so that's that. Had to school myself on hss grinding to make internal and external thread cutting tools because I'm too cheap to buy taps and dies, too! Surface finish on the external thread is meh, but the internal thread came out good and the fit is great. Scrapped two of the spindle mount bases before I got the hang of it, but overall pleased and a nice way to spend a rainy weekend.
Bad news: I learned my lathe is turning a .007" taper over a 24" span. One mountain at a time...
Lesson learned: 5/8" isn't a great size to choose for internal single point threading. You end up with a long, skinny tool with tons of flex. Something like 437 spring passes before hitting dimension 😁
Now I have to measure. The production speed could be slowed down for tighter tolerances. The buyers do the finishing so the wood has to be slightly oversized.Once dried out, how true is the lumber?
What mill do you have? I don't have equipment to move a 25' log, so I'm happy with only having 16' of track on my little mill. I rarely need lumber longer than 16', usually 8' will be plenty.Saw mills count? We laid about 2 post beam houses in a week and tossed out enough cypres to buid a couple canoes. We racked up 24 2x10 by 25ft by lunch today ..oh well brokers big money and true post beam homes. The hobby mill struggles with 25ft. I got into the controls and cnc is different than spinning and cutting logs. I wiil get some pics. I am a machine tool guy by trade and this is impressive but manual labor is used to protect the precious wood. We sell 1200-1500 oak mats a year for logging on the same mill in the down time. Oh its nice to see a 25ft beam cut out of wood. US grown and cut...kinda wild with heavy timber flying around.. Those trees are old and dragged out of the swamp. Pretty wood.
Not trying to interrupt and butt in, but man, there's so many variables. I'm pretty new at it all and was really surprised how much there was to learn. Beyond the simple stuff like what kinda tree and limby, there's other things I never even considered. I knabbed a nice white oak growing out of the side of a bank. Deep gulley forced the tree to grow way up to reach sunlight, so it had a longer than usual log before the limbs started. Thought I was really on to something. Started cutting it and the boards were curling off like peeling a potato skin. Internal stresses in the wood fibers due to growing out of the side of a bank vs straight up out of flat ground. Once released from the log the wood just went every which way. Who knew? Not me 😁Once dried out, how true is the lumber?
