Re: Removing metal splinters

Man! Y'all are lucky. I can always feel it but not find it, even with the 40x eye loup/magnifier thing.

Re: Rotary Broach holder

Your cutter should have relief on the sides. I don't know if there is such a thing as a prefab cutter. I make them on the mill. Ok. I knew that from having watched videos of them in use. I wasn't sure how you were doing it without cutting any angles on them, as in your earlier post. What angle are ...

How does that work? If the tool is held at an angle, and there aren't any angles cut into the tool, doesn't the near side of the tool interfere with the part?

Re: Best tap for aluminum

There are so many designs of small tapping heads, I don't know where to start. Frank Ford's fret site has at least 3 different ones which will inspire. Mark Klotz and many others have shown how to make these tools. The main problem is alignment, the second is speed and the third is retracting the c...

Re: Grizzly G9729 Horizontal Lead Screw

... If a guy was so inclined, there's no reason why the thread couldn't be generated single point, assuming it's not too long. Harold Especially if the new nut is made in acetal, I would certainly think a tap could be made to withstand the cutting forces for a nut that is long enough to do the job....

Re: Leveling feet ?

If you think you want to go to a stronger thread, I would think a larger 60 degree thread would be far less expensive than an ACME. ACME threads are more efficient at converting a rotating force (torque) to a linear force. That is why they are used for things like car jacks. If strength along was th...

Re: Large pan for evaporust-ing

I didn't know they made such a thing! I've used a large box with a heavy plastic sheet in it. Just have to be careful when cleaning up as it can be a mess if you don't get all the edges of the plastic.

Re: Setting the compound at 0* or 30*

I seldom set my compound slide to zero as it blocks my view of the cross slide dial... Perhaps 0* on my machine and yours are different then Glenn? Setting mine at zero aligns it perpendicular to the top slide which is completely out of the way of the cross feed dial, unless I am miss understanding...

Re: Drill Press Recommendation

...Don't want to spend more than $200. ... I would opt for a used industrial machine. Clausing, Powermatic, older Delta, Buffalo Forge ... Those two statements seem to be at odds with one another. There were some Clausings a few months ago a couple hundred miles away that were north of a grand. Dave

Re: Drill Press Recommendation

I've seen a few older Craftsman and similar machines on CL here and they always seem to want a fortune for them. I have no idea if any have been worth the asking price, as worth is completely up the appraiser. Given a choice, though, and for comparable condition, I would rather have an old one than ...

Re: Setting lathe compound to 90 degrees

It depends on how often you move that compound, but always having to indicate it back in to being parallel to the ways would get old pretty fast. If it were me I think I'd try and figure out a simple machined plate that auto indexes the compound back into being parallel using datum surfaces that ar...

Re: Setting lathe compound to 90 degrees

90 degrees to the bed? Attach a DTI to the compound and run it across the face of the chuck or faceplate. Parallel to the bed, do the same but indicate the inside of the bed ways.
