FWIW, I have bought NOS taps in the small sizes I need on EBAY like 3-48, 4-40, 5-40, 6-32, 8-32 in small batches. The taps are Greenfield, Winter, Rieff&Nestor. I recently bought 30 taps total from one seller consisting of the various sizes I just mentions for $90 shipped. That's about three...

John I've read several threads about the aformentioned multi point swing up tool (also the single point version of yours), and I just bought 6 sets of dies: 40, 32, 28 24 20, 18 tpi. I don't quite see how you construct the the tool holder. In looking at the die it appears as though it is meant...

Thanks for the replies everyone! Well after stewing over it for sometime now I've decided that there is most likely only one efficient way out of this mess. Touching on what Sk8Tr has said: as it turns out I recently bought a Buck Adjust-tru six jaw, which is what I want to use primarily. Like...

I have a Lathemaster 9x30 and would like to have a D1-4 camlock system on it. Right now it has the stock brain-damaged chinese quasi camlock. Where the studs mounted directly on the back of the chuck go thru holes in the spindle flange and a so-called locking ring. This so-called locking ring is...

Given a circle of radius R with a chord with a length of 26in. At the midpoint of the chord there is a perpendicular bisector that intersects the circle and has a length of 3.75in. Find R. This is a real world problem that came up once or twice in my career. It can be solved by 3 simultaneous...

That's one of the problems. No 1 there's NO automatic downfeed on my mill. Therefore using a boring head with hand downfeed, there will be inconsistent SFM and feedrate so most likely there will be chatter, inconsistent bore size, and inconsistent surface finish because the pressure exerted on...

here's my compound & cross slide; (by the way that's preservative, not rust! ; when this photo was taken a time ago): I guess what I could do is to buy one of these from http://www.statecollegecentral.com/metallathe/A-11.html and machine the dovetails etc. to make a replacement. It's a 1/4"...

Thanks everyone! Well it was late last night so I forgot to mention key points: The mill has quite a bit of reach in z... 12 inches, so a boring head could go down through and back up and clear the part. Second. The 9 x 30 lathe does not have t slots on the cross slide. I asked about getting a...

The critical dimensions are in bold with tolerance called out. In general for the other dimensions .xx plus minus .010; .xxx plus minus .005. THis is for the beginnings of a crosshead guide for a steam locomotive. I would rather NOT do it on the lathe because it is odd shaped and there in no...

An interesting variant of this problem is when the radius of the circle is NOT given; but you are given x and y: solve for the radius. It has come up but rarely in my professional career as a CNC machinist and at home as well, but nevertheless it has turned up. Matter of fact, coincidently a...

I have a bottle in front of me (Smithwick's, which I'm enjoying thoroughly; several actually) so I might be a wee bit off base here. Actually, I would use the Law of Cosines, rather than the Law of Sines. Wait a minute. Looks like I spoke too soon... I kept pondering Kens statement "...can...

I'm located in Ohio; I should probably put that in my user profile so it appears in my posts! Edit: which I just did -- the location shows up now!

When you say models, do you mean actual Panhead engines or working models of engines? As far as my plans on the Panhead: well, what I'd like to do is build a working 2/5 scale Panhead engine. I've bought some actual '57 Panhead cylinders, cam cover and few smaller parts to measure and scale...

Hi Everyone! My name is John and I'm a CNC Machinist by trade - I work at Swagelok in the Valve Division making high pressure fittings and valves, stainless mostly. Incidently I don't use any of their fittings in my model engineering projects as they're just a bit too big! My shop consists of...

When I have gone to the downloads index posted by Gail in NM and clicked on a link it just leads back to the Home page. Not sure what's going on.
