'Make From' ... That's proper Production Engineering

Does "Lazy" = maximise accuracy? DISCUSS Omit references to personal satisfaction.

Adrian,

Very nice work. Envious.

And as Eric Morecombe used to say "You can't see the join"

I'll start the ball rolling, Howard

My opinion, as recently stated, is that in this 'Make From' example Lazy = properly Production Engineered.

The caveat to that is that what you use as your 'From' needs to be to supplied an appropriate specification; otherwise it's just 'Raw Material'

Your logic ... that commercial components can be more accurate than self-made ones ... appears sound: But in the 'hobby' market reality might not match expectation.

MichaelG.

Quite right, Michael, caveat emptor.

My starting point is that hobby machinery is unlikely to be of rigidity, accuracy, and quality equal to proper industrial machinery. Nor are most of us likely to have precision grinding facilities to match commercial products.

Yes, I have made tapers that match the the equivalent part, but mostly when I have no alternative, such a Jarno taper. Making ER clamp nuts is not my hobby, I prefer to spend my time producing the mating part that is going to be unique to my workshop / tool.

Yes, I cut gears, that I could buy. probably because I am too tight fisted, and relish the challenge. Just like those who enjoy making Morse tapers. 16 degrees included angles I can manage, 2 degrees 52 minutes for a 2 MT is too much bother for me.

We all have different desires for our hobby. Each to their own, and full credit to those who produce high precision work on what are fairly humble machines.

Fortunately we do not have to make our living by making thousands of identical items That is a job, not a hobby and leisure activity. Most of us have those days behind us, or do not wish to participate in such activity..

fat fingers again!

Come on, folks ... take up Howard's invitation to DISCUSS

MichaelG.

I think one has to be pragmatic. I made a value decision between buying an arbour and making one.

• I am time rich money poor.
• I want to improve my skills.
• Self satisfaction and bragging rights.

Regarding accuracy? reading posts regarding budget tool quality, I am dubious that at the price range I would purchase at that they would be particularly accurate.

Will I make another one if needed? probably, it seemed easy enough and kept me amused for a couple of days.

I am now trying to decide if I should make a parting tool holder or buy one.

Further down the road, I can defiantly se that I would opt to buy like Howard. He is working on bigger and better projects. All comes down to ones personal priorities.

Adrian

Well done Adrian. It looks good. If you make a gang set , you can always make another cap to suite that length.

Also you can make different caps, to suite different ID saws smaller than 1 inch, by adding an adaptor ring to either the cap, or into the main holder.

There is lots of advantages to making your own tooling. One being you know the accuracy of it, sometimes you learn another skill in the process as well. It is best to make the cap of a different material to the body, to reduce the chances of it galling or picking up.

This came with the lathe tooling, quite a neat idea with stepped mounts for different size blades and they are sprung so as you fit the cap they push back, you wouldnt think there is enough space for them to push back but they do until the blade meets the shoulder. Dont know where it came from as there is no name on it, I had my doubts as to how well it would work and hold the blade but a quick try with a 1.5mm blade and it worked a treat.

Looks like the gods are smiling on you Ron! My guess is you've bought a lathe and tooling from someone who bought carefully and knew what he was doing. I own a similar slitting saw holder and it's a shade too wobbly for comfort. Works OK but it's slack enough to irritate me, which is why I made a few solid versions. You seem to have a better made holder of the multiple type. Using it in anger will confirm, but it looks good to me.

Dave

Ron has really landed on his feet. Good luck to him!

Not sure about my working on bigger and better projects. Bigger/ perhaps, but not more complicated.

Have far too little patience to take on anything involving much time. Biggest projects in many years: Four way back toolpost, Worden Cutter Grinder, and now a mMchine Vice. Definitely NOT enough patience, or skill, to spend ten years making a loco, or a road engine.

Better? Most unlikely. Not many precision devices make it out of my shop! ANY?

Keep at it guys. Tremendous sense of satisfaction in solving a problem, repairing something worn or broken, and seeing the end result.

99% of the population won't even know what it is, but YOU do; and YOU made it, so that it works! You have made or done something that very few others can! It may even be the only one in the world! Posibly inspires others.

That's how the hobby brings pleasure.
