Dave,
Thanks for sharing. I am pondering over how much stress is enough to keep the flexible host & Y-car happy.
My MM is cutting & squared. Have not face the spoil board yet due to foreseeable mess by the dust, will do facing once the DC is in operation.
Getting the decal on is harder then building MM... So no number yet but that really doesn't matter to me... Anyhow, I may just resort to cutting a few wooden sign & stick them on...
can't devote much time to work on it lately as work has to get in the way. Moreover, time were chewed up by the CAM software learning curve...

Hi Chopper, good to see you back. Did you ever get that roots vac hold down working? I got mine up and running on a 10 HP setup. Not perfect, but for the money spent, one would say it's perfect. Very usable. Anyway, Good to see you back.

Oh, and a quick video of the table surfacing at 500 ipm, probably could have went faster but I wasnt in a hurry and it was my first time surfacing.

Having a friend make a mounting bracket for it, going with 3/4" alum and machined to fit the z-stage, quoted my $40 USD, not bad.

Vintage phonograph cover

My dad had an old phonograph and the front decorative grate was broken and missing parts. I scaned in the part of the grate that I had and drew around the good 1/4 that I had left, then mirrored it both ways to get symetrical. Here are a cpl pics, before and finished. I cut it out of 1/4" plywood.

Sorry for the delay guys, havent checked my email in awhile.
Robert: I used a 1/8 upcut endmill. Wanted to use a straight but dont have one so I cut it upside down to minimize lifting of the plys.
Ken: It is 11" x 14.25"
Gorantec: I bought it off Ebay from LovesHappyShopping, around $525 USD total with shipping and received it in less then a week, Very happy with it so far.

Robert,

Here is a 3kw air cooled version I got off of ebay.

http://cgi.ebay.com/3KW-AIR-COOLED-S...item3cb098a68f

I have been running it on the bench for a few days and am fixing to install it.

So fare so good. Got it in 4 days. Seems to run very well.

hint: if you want one offer him 450

Kenneth

Ken,
Does this unit have a fan or is it fed with shop air?

The fan is mounted to the top of the spindle shaft and blows air down through cooling ports when the motor is running.

I ran it 10 hrs straight yesterday on the bench. It got warm, but not to hot to hold.

The vfd comes with a chinese manual, but the guy selling it will email you an english pdf version.

I went with a liquid cooled spindle, way less noise. The only thing I hear is the bit in the wood and the steppers. I can actually hold a conversation while cutting!

With my dust collector and everything else running in my shop, noise it not really an issue. It is about half the volume of my old PC router.

I have been told not to use the pump that comes with the water cooled spindles though. When the pump goes out the spindle dies. The folks I know running them are using pumps for small ponds.

Just FYI.

I hope you have good luck with yours.

I am using spindle from Deitech 2.2kW watercooled, even if the water pump die it would not overheat in a second and die. And it costed 300EUR with shipping. No rust at all on the spindle body like some received their from ebay.

Mine didnt come with a pump, but I am using a small pond pump, seems to work well. Like danilo said it doesnt overheat rapidly, and actually I think it would run quite awhile with just the water in the lines but I am planning on getting a flow meter and hook up an alarm just in case. Speaking of rust, I was told to run a little anti-freeze in the water for corrosion/rust inhibit, what do you guys think?

Does anyone know what the guys in colder climates (like Canada ) would need to do in the winter months? Antifreeze instead of water is a given, but what about running the spindle when the shop is in the 30's? Preheat the coolant?

Heath,
Im in Minnesota so it gets cold here too. I keep my shop at 50F when im not using it but I was also thinking about using a aqurium (sp?) heater to keep the bearings at operating temp, just not sure what the op temp is for the chinese spindles. Anyone know?

Etching a Mirror

I did a test on etching a old mirror I had laying around. It was a real cheap mirror and only about 1/8th in thick. Broke the first one using too much tape to hold it down.

Heath,
I used a 60 degree solid carbide bit from Rockler (US) with a .005 depth, 60 IPM @ 17K RPM. I didnt have a big enough piece to make the text look good, the piece is about 2" x 3". I am going to try the wife's good mirror (1/4 thick") this week HOPEFULLY with good results. If you noticed, the etch down the right side is when you dont start the spindle and bring it to x-y zero and not lift the z, no broken miror or bit. I will post pics of the good mirror if it turns out good and she doesnt kill me lol.

P.S. Anyone notice the font?
