I got a question for machinistsWhy is it that you guys can cut titanium to fractions of a human hair width with crazy amount of repeatabilityBut none of you guys seemed to make a marriage last?How’s it feel knowing that you see a Burned in CRT screen on a machine control that’s going to be in a scrap yard after you die more than you see your children?

Has anybody here tried out a desktop CNC machine like a DMC2 or Carvera? I know they're less than ideal for steel, but the idea of being able to fabricate metal parts in my garage is very appealing.

How much does a brand new lathe and mill depreciate in value?

What's the best free offline CAD software?
Have done 2 gymnasium courses with Autodesk inventor and I'm doing one with solidworks right now, but since they're p2w i most likely won't be using them for hobby purposes.

Taking a community college machining class, made my first chips today. Looking forward to really getting into it next week.

Picked up a sherline 4400 lathe and the matching mill, along with a lot of tooling, for very little. The previous owner used them for rc cars and steam engine models.I don't have a real use for it but the price was too good to pass up and it seemed fun. Other than being tiny they seem very highly regarded. For what I paid they're cool conversation pieces of nothing else.Does anyone have a good idea for some starter projects? I have pretty much all the accessories other than cnc parts, the rotary table, and the threading tool. I will probably buy the threading tool since honestly using a micro lathe as a threader seems pretty useful and setup seems easy.So far the only practical thing I've done is face some rough cut aluminum and brass rounds. I make challenge coins on a fiber laser and its hard to find decent quality brass blanks nowadays that aren't 1.5" or smaller. However this lathe doesn't have the oomph to part something that thick easily so I use a bandsaw.I do have a onefinity I use for aluminum and brass sometimes but no real manual machining experience other than wood.

why the fuck is it "machinery's handbook" and not "machinist's handbook" or "machinery handbook."

if i bought two alibaba sliding tables and bolted them to an L shaped pipe frame, would that be a viable mill ?

would this be wacky? getting two cheapo 10lb weight plates, true the edges on both of them on my home lathe and then put a radius on either side of each plates corner so the two plates can come together and form a tube bending die. i probably wont do it
A
Anon10/15/25, 11:45No.2950942
so I already have some plates. I got my idea cause I used a plate to make a bending die for square tube. for a round die I think im gonna use 5lb plates because they are only 7.25" diameter and thats a good radius for the round tubes I want. I think i will make a mandrel these will fit on and then turn them both at the same time. I would like for one edge be 1/2 for 1" tube and it would be nice for the other side to work with 7/8. Im trying to think how i will make the bending side, maybe get another larger piece of tube with a thick wall that 1" tube will fit into and then cut it in half.

im going to use a 2" pipe nipple for the mandrel probably a cap too for the center to get on. Ill open these center holes to 2.25 and then turn the pipe down to fit. im trying to keep this low cost and im trying to think of something menards would sell thats big enough i can use as a bushing. maybe bearings from amazon.
A
Anon10/16/25, 22:41No.2951213
to make the bushing I will modify two caps, turning them down and center drilling them. since they have such a big OD I decided to not bother turning the pipes diameter, only to just get it straight. I haven't cut a radius on a lathe and im wondering how I should cut a hhs bit. I only have 3/8 hhs so I was thinking about making a left right and middle profile or welding like 3 togther. im not sure.
A
Anon10/16/25, 22:43No.2951215
like this was an idea where I would take 3 hhs blanks (I have a lot), tig them together, and then trace and cut out my radius and then trim down to the holder, my 3/8th lantern style holder

Im gonna give this a go. why not
