An exercise in frustration, being a hobby machinist

[Janderso]

Bet it will work anyhow. How was the .002 tolerance determined?

It’s on the print.
Plus, I want to hit the targets.
This is where you get to know your machine.
In order to measure the spacer, I had to take it out of the collet, determine how much more to cut then try to get the single point tool just touching the shoulder.
I must have got it wrong.
The tolerances are the challenge,fun but frustrating.

Making stuff by plans is truly where I found out how much I needed to buckle down.

In my world missing the dimension doesn’t =scrap. It’s now a future part and I now have some metal tins I keep them in because until I got hip to that fact I was always trying to hunt up those near misses because they would have worked for the project at hand. I also have a tin for machined left overs of various dimensions. That tin is constantly rotating because I’ll need a special spacer for a jig or small part and adding leftovers.

They are only scrap if they get tossed in the trash. And the sanitation engineers have taken it away.

Having a crappy lathe helps, cuz then you can always blame the lathe

My bins of shame (yes plural). To be fair I was prototyping as well as screwing up.

I bought your kit.
The second go went much better.

Lucky for you those are some of the simplest parts in the assembly. Wouldn't want to scrap the side plates.

Oh no, we wouldn’t want to scrap the plates. Lots of work here.

Letter stamps to keep the sets , very nice.

I couldn’t end the day with frustration. Now I’m cocky and ready for my next challenge.
These came out within specs.
The larger pins will be drilled and tapped right down the middle, I hope.
The edge finder is a valuable tool.
Made the drilling and tapping a simple step.

Those knob graduations, plus any backlash(if not taken out)drive me crazy, I'm still practicing with the DRO, it ain't infallible either.
Each part of the line on the knob is wort 5 tenths front of the line, the middle of the line, and the back side of the line it seems

I must add to your comment. Your DRO is only as good as the amount off wear on the bed,like my lathe, especially close to the chuck,like my lathe and backlash on the crosslide...........like my lathe(need to adjust that).
