What did those end up going for? Sounds like everyone was in on the bidding. I hope no more that $100 for the pair.

Sold 45/35 so 80 all in.
Need to install a bunch of hardwood flooring. Scored a deal on a Bostitch nailer and 10,000 nails.
$180 CAD for the lot. The nails would cost $200+tax on their own and I needed most of them, so basically I got the $500 nailer for free.
I might get lucky and only use 6000 of the nails, leaving 4 boxes of 1000 each to possibly return for store credit to somewhere that sells Primatech nails. Each box of 1000 is an individual UPC'd container and most places will take things like this in for store credit. Might get $80 of my investment back

Finally had a hour to get my cnc retrofit hooked up on my Bridgeport, and running. Been sitting here since April. NMTB30 tapered chuck and a collet set are in route. Pretty much just going to use this one to do rear sets on.

Personally for the work I did, I preferred the z axis dro only with x,y cnc. Without a tool changer, there isn't a ton to be gained with a z drive. Not like you can hit go and complete a part anyways without a tool changerJ-Rod10 said:

I do lots of 3d parts, so z-axis is necessary. But a lack of auto tool changer is a scenario you learn to work around. You figure out how to get the longest runs out of an individual tool, and you have to be willing to sacrifice a little extra material or add some run time to avoid a tool change. Is it perfect? Nope. But building/buying a tool changer can be quite a project. And the time investment involved in accurately generating a tool library can be fairly overwhelming if you don't actually get to do it for a living. Setting up runs with fewer tools also means less chance of really fucking up. My latest project was to install a web cam on my machine. I go drink beer on my porch with the web feed up on my iPad and when the operation stops for a tool change I wonder back to my shop and perform the change. An auto tool changer would be amazing, but so is drinking beer while work gets done.
J-Rod, what Mach screenset are you using?

very true. my time behind a mill was mostly doing fixturing or tool and die building. I ran a hurco vmx42 (24 pot tool changer) for the long run stuff with lots of operations, but for one or twosies, you couldn't hardly beat a cnc knee mill. My dad runs into the same thing you mentioned. he does 3d machining for prototype work and some for hot drop forge dies, but when he bought the machine years ago it was a huge investment by itself, let alone the extra 8k he would have had to spend on the took changer. now he often just runs it lights out after he goes home. when he comes in in the morning he finds out if he lost a tool or not haha.
anyways there is more than one way to skin a cat. I didn't mean for it to come off that I thought a powered z axis was useless on a mill, just for what I was doing it was almost quicker and more efficient without it. but then again, we weren't using that machine much for production, just for the one off stuff mostly.
The profile was built by the guys that built the control specifically for that control. Just downloading Mach, and telling it to go doesn't work.Sav0r said:
Tool changer is nice. Lathe, I can fill the turret, and just run her until she needs more stock. I've got a milling center waiting on space in the shop. Which has turned in to building a new shop with another 5,000 sq.ft. For the time being, it'll continue to be the two manual mills, a Lodge and Shipley lathe, the Bridgeport, the Mori, and the K.O. Lee grinder. When we have more space, going to start phasing out the majority of the manual milling. Most of what I do outside of bike parts is turning work. So, it works for now. But, I do like button pushing.
