What tools do you need to be a "sheenist" ?' what a wonderfully simple question, asked by a wonderfully simple person. Am I in the right forum here, looking for skill or potential thereof. You need a...

Servo motors have permanent magnets in them, you take out the rotor and put "keepers" in the stator to prevent loss of magnetism. He's going from 35 mm down to 22 or 24 mm - how long do you think...

You cnc guys make me laugh, the only thing you know is inserts and how to push a button.
I've ground drills (by hand) to cut within a .001, bored 16" deep, holding .002 in a 4"bore manual lathe (not...

Way to go!!!!!

The way you turn down servo shafts or any motor shaft for that matter is to take the motor apart, ( after all is was in pieces before assembly at the factory ), Put "keepers" in the stator to prevent...

I know exactly what material to use, and what Rc to harden to.

Gear cutting and Hobbing - sulphur based oil is the only way to go - it's all about lubricity.

How about you take a basic machining class.

Nice work, can't believe anyone would talk to customers that way in this economy when every relationship is precious. I would seriously somehow try to spread the word about these As$#les. Always nice...

Need a driver ? i have 20 years exp. clean licence and know N. E like the back of my hand.

Why did you start using a different welder ?

You need an undersize reamer, available at MSC idustrial supply, for example.
Drill the hole about 11,75 mm then ream thru'.
Experiment with different speeds and cutting fluids as this can affect...

Full depth of cut - one pass, flood coolant, 100 SFM. 12L14 cuts like butter. I love it.

I think you're gonna open a can of worms with this one. Get a spray-mist set-up and be done with it. WD 40 is not a cutting fluid ( although it does work on some materials - mostly plastics I've...

Good answer.

Jig grinding, pure and simple.

You know what - what has to happen here is that a 3/32 dowel pin gets knocked into a hole with a hammer, that's all. However, it's Sunday here so when I get to the shop tomorrow I'll see if I've got...

Home based, advanced cnc machinist, 8 years????? I been doing this for forty years and do not call myself " advanced ". Who cares how much a bit costs, that gets passed on to the customer, and if...

I used to machine Nitronic 40 all the time, space shuttle main engine parts. Not really too bad, heavy feed, tons of coolant and a little bit of know how.

The only comment I have is - Wow - don't know if this will work but looks great!

The slitting saw, I like that the best - probably where I would start. 1/4 end mill x 1.5 Lg. the slots gonna look s#$t by the time you're done.

Why use Allum ??? there has to be something lighter and more "moldable" to suit your application.

Full inspection every 1 in 10 parts seems to be the norm. Tight tolerance work perhaps a little more frequently - or at least the dim. with tight tolerance.

I ran an Okuma LB 40 with upper and lower turret years ago and yes, of all the machines I've run it is absolutely the most rugged and would just go and go. In fact I'm not going to take part in the...

If you know it's metric thread the rest is easy. General rule of thumb, subtract the pitch from the o.d. this will give you the minor dia. (approx.) Metric always 60 degrees. With this info you have...

Are there any kind of prints or sketches available? I know nothing of guns or calibers but am interested in making one of these.

Take your valves to an engine builder, he will have the correct machinery, they will be "dead nuts" when done at a fraction of the time and cost you are thinking of putting in to this "project".

Sounds like a Brand name - 4140 is a heat treatable steel, comes annealed or with some hardness to it. Millmark has a good point but I think the spellings are too far apart. Be safe - talk to your...

Just don't drop it.

Not looking to win - but enjoy debate.
What do you make?
