Ever since I seen the covers Dan made, I had wanted some. So I had a bit of extra time on my hands a few months ago, and got started on a set of three. They still need some components to make them complete. They might get done this year, or they may not. Heck, they may never get done. If I purchase that Seiki I have my eye on, these would be null and void real quick. That's not very likely though. 5K+ just to rig and move the dinosaur. I guess my home-made machine will have to do a bit longer. It's been a real workhorse for the past year, so I can't really complain.

Made this master cylinder cover for a friends murdercycle. Went a couple thou to deep with the center drill and lost a bit of detail, but hey, it's not bad for using a center drill as an engraver.

Tangent Corner / Reid Supply sale
« on: December 01, 2010, 11:28:48 PM »
Looks like Reid is having a decent sale. Figured I'd share. I think I'll get me a pair of 0-8 digital calipers for $15.00. I know there not highest quality, but everybody needs a couple sets of cheap calipers!

Ran across this and figured I'd share. The comments at the end are a good read, too.

Show"N"Tell ( Your Machines) / Harbor Freight 12X36 (not CNC)

Work on the mill got put off another day, because I had an opportunity to get a small lathe. I didn't really want a small bench lathe, but the price was right, it was practically brand new, and it was a whole lot better than the other lathe I don't have. Oh well, "carpe diem" as they say. I did see a few sprinkles of aluminum chips, some carbide tipped tooling that had been sharpened wrong, and a couple other "tell tale" signs that somebody obviously didn't know what they were doing, and lost interest in a New York minute. The date says 2002, but the grease from the factory is still covering everything, and lots of stuff still has the rice paper around it. Not even a scratch on the back splash. If it turns out to be a halfway decent lathe, I might CNC it in the distant future. I see Ron Ginger has already converted one, and Rich done the Atlas. Now I know who to ask for any questions I might have.  ;D

Well, I think I'm about ready to purchase a spindle motor for the mill in progress, however, I'm about as dumb as a box of rocks when it comes to choosing a motor. I'm thinking a VFD with a good 3 phase motor would be great, but I really don't know enough to make an educated decision. I've seen that I can get a new 3hp Baldor or Leeson motor for about +/- $200 delivered. I've dug up some specs on some motors, but I really don't know what I'm looking at.

2 or 4 pole? Pro's and con's? I would like to have more power at slower speeds, rather than higher, so I guess a 4 pole is more desirable?
What about VFD options to look for? Needed inputs/outputs for features that might be useful, relays, braking features, fieldbus options, etc.... I have a small bit of experience with the Danfoss drives, and I know they are quality drives, plus and I have a local supplier, so I'm kinda leaning toward those.

I know I'm asking allot, but any help at all is appreciated. Thanks!

Others / Circle holes constants chart
« on: May 01, 2010, 08:40:37 PM »
Here's a handy dandy chart that gives evenly spaced hole locations around a circle. It's came in handy several times on the shop floor, especially when you don't have time to sketch something out on the computer, or don't have access to one. The PDF file is clear and can give a good print resolution, unlike the small photo.
