|Thread: Rust Stain on STONE|
Yeah, I had an old Sky dish rot onto concrete. You couldn't tell afterwards.
Builders' brick acid will do it.
|Thread: SPV Tapping Head|
Just google "tapping head manual" they all work pretty much the same.
|Thread: Trephining - Do's and don't. ??|
Why is there no other word for thesaurus?
But seriously, it should be similar to a parting tool but shallow to clear the curved sides. A round tool bit ground down to the diameter works well.
You only learn by doing
|Thread: Use of Mercer dti|
Difficult to know without pics. However the stylus is not guaranteed to be on the centreline of the body. That can introduce errors.
The dial can be zeroed at any time by rotating the bezel and lens.
|Thread: Stainless Steel Knife Point|
That's about the same hardness as mild steel. It would wear rapidly, especially with wire wound strings.
Loading would be difficult to work out. The load pushing a string sideways would be different to the tension and both would increase rapidly as distortion increased.
|Thread: Stereoscopic Loco|
Google stereoscope. It's a new project for you
|Thread: Problems with G-code etc.|
My experience on industrial kit is that offsets can be plus or minus from the master tool and the controller sorts it out.
I've never had to alter programs since I used dedicated toolholders and a common paramters file. A 20 station carousel on the machining centre was nice too.
Shhh it's a secret
|Thread: How to rivet in straight lines?|
Tilt the punch 45 deg away from you. Place the point on the spot and pivot it upright. It can be done. Opticals require more elbow room on the surface.
|Thread: Registering with various Merchant's sites|
E-shop packages tend to be off-the-peg website add-ons.
They are set to mine as much data as possible. This is intended for mail shots, analysis and selling on. Sometimes they even sell to spammers who have no more right to live on God's clean Earth than a weasel.
It isn't necessary, it isn't right but it's the world we have.
|Thread: What did you do today (2015)|
A custom muzzle thread protector. Very happy with the hot bluing.
|Thread: Lathe chuck indexing?|
Ha ha, it's easy to spend someone else's time and labour
I'd go for 12. Then you get 2,3,4,6,12.
You haven't quite grasped the geometry there I'm afraid. Having no worm drive it has no similarities with a div head.
To do direct indexing you would need 40/18 = 2.22 teeth per slot. Not only does that clearly not work out but a lathe spindle doesn't lock either.
I once worked a lathe, possibly an Edgewick or Holbrook that had an oversize spindle gear which was graduated for multi-start threads but let's not go there.
With such limited kit the closest way is to put the stopped mill into low range and hope while plunging. If it's a vee spline you'll have to line up with a scribed line once centred. I will be an approximation.
|Thread: wanting to buy a surface grinder..... swing type ?|
That's not a surface grinder actually. It's an oscillating head, rotary, cup wheel grinder. Very niche.
It grinds the top flat. Even a Lumsden has a tilting table.
If you have a single specific task then ok but not only is this one rough, it can't do shoulders, angles and would be a dog to dress.
I think it will disappoint I'm afraid, sorry.
|Thread: Excel Query|
If you organise the data well then the Filter command will do what you need.
For instance, if the top row is made of header names then you can set all that row as individual filter elements.
Google it if you want to know more.
|Thread: Asian High speed ER collet spindles|
There's a reason standard machines don't go to those speeds. However if you want to try it then why not look at a speed increaser as a compromise?
|Thread: What did you do today (2015)|
Hmmm. The previous owner of that gun was quite a cowboy.
|Thread: Whats going on with this drill?|
Know a friendly PAT tester?
