Mirroring a part

I need some advice on how to use G50/51 (Centroid Mill) I am getting ready to make some knight chess pieces to complete the chess set I started years ago. I have the knight profile all done and I have the CAM complete except for being able to chamfer the back side of the knight. I have my stock for ...

Re: Milling a helix

I find them to be much sharper and provide a much better finish than HSS end mills. I'll have to agree with Glenn, I've gone to all carbide end mills which are all made for specific purposes. 3 flute with special coatings for aluminum and 4 flute and a different coating for steels. I had some .200"...

Re: MIG Pulsing issue

Ctwo, I too ran into this exact issue with my "Cheap" Northern Tools MIG. What I found was the wire feed mechanism was not feeding the wire constantly because of a binding problem in the feed path. The little guide that guides the wire into the feed wheels was loose and would slide into the wire fee...

Re: Milling a helix

I purchased enough material to make two worms. I'm hoping I don't need the extra piece.
You'll only need it when you don't order the extra piece! :wink: At least that is how it works for me.

Owesome project, looking forward to seeing the finished product.

Re: Milling a helix

Both yield 120 volts to neutral The reason for the "blanked off" spots is that the "Wild Leg" of 208 does not produce 120 volts to ground. So you should not put a single breaker in those slots! Quick way to tell if you have 208 Wye or 240 Delta is to go out and look at the transformers on the pole....

Re: Milling a helix

Picture a large kitchen bread-dough blender, but for sand. Usually wider than deep, with slow moving mixing blades.
Many variations of design are possible. Even a cement mixer can work nicely.

Thanks,

That was pretty much what I found on the Internet when I did a search for said item.

Re: Milling a helix

Getting my muller operational is one of those things
Any chance of showing us a picture of what a Muller is? I'm thinking it has some use in the melting/casting work but I've never been around any of that to know what you are speaking of.

Just curious..

Re: Milling a helix

Well isn't that slick! I love some of the ingenuity found here from the members! And more to the point, most of the really good stuff I've learned in life I learned from someone older than me. Older people know stuff because they've been there and done it! That is a very well thought out solution H...

Re: G0678 CNC Conversion Build Log

I got the chip guard finished! It works pretty well and it just lifts out of the 1/4" channel when I need to make a tool change. I may at some point add a back splash didn't spray to far to the rear so maybe I'll just go with it as it is. I made a 4 1/2" table extension towards the front of the tabl...

Re: G0678 CNC Conversion Build Log

That said, did you lubricate your tap (perhaps each hole) before tapping? Yes, I put some clear thread cutting lube in and around all 5 holes and some on the tap. Because it is clear, it does not show up very well in the video. The product I used was something I bought from Grizzly and I've had it ...

The mill is complete!

I made a video of 5 holes being rigid tapped if you want to see it run.
