BUMP!!

break down what you think your machine teaches into chunks. Mechanics, electronics, programming, artistic expression, CAD etc etc etc. Then take one area at a time and break that down...

Thank you moderator for moving this thread..

and thank you Fastest for a reply.. So 48V for higher torque? Overall speed is not that important Ive gotten used to running with my 13V supply.. ...

Hey everyone, it's been a long time since I've stopped in -my machine's been working pretty much with zero problems for the past 7 years! I built a PDJ pilot pro from patterns in 2007 using hobby...

Jeff, thanks for the tips! I'll try to take a look at it under magnification and see what's really happening. As long as the next wax is better I'm happy. I'll get it soon enough.

Hey, I know this is the software forum but I figured there are more wax cutters here than anywhere else.

I use a 15degree, .005 carbide "profiler" to cut my wax. 30krpm spindle. .002 stepover. I...

I use a macbook pro (On the PC side) and it runs flawlessly.

Check this out guys, might be useful!

you could take your legs, and build a rubber mold from them. (one at a time) Then use that female rubber mold to cast wax replicas. The wax replicas get encased in high temp plaster (investment). ...

thanks fixitt, thats great info.. amazing work!

Fixitt, do you use any type of oil or lube to help clear chips? I noitce wax tends to gum up and melt on me. And how do you get such fine detail? you must use .001 offset per pass? Very slow...

Anyone? really?

Hey guys, I have a bridgeport 12" rotary table and would like to be able to index with it. (as opposed to using angular degrees,min,sec translation.)
I'd need the plate(s), handle and sector that...

The hand torch is better at localized heating too..

Cool design joe, are you going to build it??

Thanks, HuFlung..

we threw out a ton of the stuff but I kept a gallon of each for general use.. It should last me a while and then I can get something more specific if I need.

Makes sense...

Hey there.. In the flammable stuff cabinet in my shop I found a few gallons each of "Dark cutting oil" and "light cutting oil". Whats the difference? I've been using the dark as a general purpose...

Jesse, I like your technology (abs printing) but the price is out of my range. Maybe a used machine? Do the pumps/nozzles wear out? Are they rebuildable?

I want my parts to be "real" -actually...

Hey all, my district might have some money (Around 10k$) in the next year or so to spend on a new machine(s) for the tech lab. I was wondering your thoughts. I was considering either a rapid...

yeah Im pretty happy.. I didn't even know this was there until the first day of the new job! Next will be the old lathe in the corner.. Defninitely not a brand new machine under cosmoline, but its...

Thanks George, will do!

~Steve

Well, I spent a few hours with the machine today and the prognosis is good. Instead of light rust everywhere, it turns out that the red color was just dried oil or cosmoline, becasue after a roll of...

All, I am recently employed at a HighSchool with a technology lab. Turns out they have a Bridgeport from either the old metal shop or auto shop. It hasn't been run in i'd say 5 years at least. ...

maybe get a variable speed controller for your machine? run the motor at maximum and then use the variable speed control to slow it down, might work to get your rpms down.
Ive got some plastic on...

hmmmm thanks for your insight there Bubba. Im going to experiment around a bit more with depths of cut and speeds feeds, and see how it goes.
Id like to use coolant but I don't even want to...

Hey all, Ive been trying to engrave some text, and while its coming out OK, its not perfect. the problem is that the edges of the letters and paths have a burl or flash on them, raised above the...

well, if you want it as an outdoor headstone type of thing a lithopane probably isn't the way to go, right?

id go with something out of sealed wood, then wipe some stain into the carved image to...

Id say double stick tape (thin kind) but getting the work off the table without it bending seems like it would be an issue. I guess you just go slow with a putty knife.....

soon to be cutting...

Hello all, I am looking to do some cutting and engraving of aluminum plate. These parts are purely decorative, so strength is no issue. I would like to know if there is a "best" or easiest alloy...

Hello I am about to purchase some aluminum plate for engraving, and would like to know if there are any better alloys to choose with engraving in mind?

thanks
~Steve

Nice! Is there some kind of infill, or is the darkenss caused by the depth of cut? Have you experimented with different alloys for engraving?

keep it up!
