Workshop and machinery mods and tips,

added dro’s to the lathe cross slide and saddle the small one came from banggood the long one off ebay, look like the same units.

also found these 2 screws loose they hold the nut for the cross slide .may explain some inaccuracy I have been having (perhaps cuased from milling?)routine maintenance I guess.

You won’t know yourself with the dro. Nice mod.

Nice! A DRO on both axis. I only have one.

Not a mod but an unusual request, I had a work mate ask me to buff up his darts. Using the lathe also made it easier to straighten the bent ones. Here are some before and after shots.

At the owners instruction I didn’t do the body on these ones as he wanted to retain the coating. Just the tip, tail and grooves but I did forget to clean out the rear grooves when I took this pic :person_facepalming:

So by the end I figured all I was doing was cleaning his sticky finger jam off :confounded: It was a fun little project that didn’t take much time.

I started this a couple weeks ago but didn’t have an 8mm tapper so only finished it this weekend. On my drill press I ground back the mounting point for the depth gauge so it’s flat across the top. I didn’t get a before shot but it was an awful angle that point loaded the nut.


I also added another guide/aligning screw to give it some rigidity and spin true. I wouldn’t say it is perfect now but it’s much better than it was.



Whats the two threaded bolts in the main housing for?

That’s the guide/aligning screws (sorry I don’t know the proper terminology). You can see a groove in the spindle shaft (above the chuck when it’s extended down), these screws stop the shaft from rattling around in the main housing. Other (more expensive drills…. yes I cheaped out……again), have a bolt that clamps the housing around the shaft. This model relied on one screw pushing into the shaft. Now it’s got 2.

Hope I explained it better this time :blush:

Quill Lock.

Lol, okay, quill lock. But if that was it’s intended use then that’s not what I’m using it for. Without these screws done up snug the err quill slops around and drill bits fly around in little arcs.

Guide bushings a little worn out, eh? Oil Lite or Ampco Graphite Bronze bushings? :+1: Or is your quill guided by the Cast Iron Housing? :cry:

Yes. It’s a real cheap and nasty.

Thanks pp. got it. I dont recall seeing them before on drill presses.

This one is ripped off from Mrs dnf ,sorry Steve.
For machining parts you don’t want to damage, just machine up a thin wall split sleeve

good to use a reference point on your chuck, I use the made in china badge

I have a dozen or so split tubes all different sizes. They keep growing as you never have the right size. Its also a good way to hold tiny parts.
Yours looks like it was made from a hydraulic cylinder rod. :+1:

Knurling:
The exact outer diameter of the working piece does not matter, the profile will adjust automatically. Just make sure to drench everything in coolant or oil or whatever you use to wash the small chips away and preventing them from getting pressed into the profile. Additionally if you have a cheap china-tool like I do lot’s of oil will prevent the knurls from jamming with the axis.

Cheap lubricant/ coolant for machining:
Rapeseed oil. Does wonders if you work with copper, will prolong the live of your tools compared to dry use and isn’t as messy as real coolant.

Indexing with the lathe:
Prepare to cut threads with the same pitch as the lead screw. Let’s say your lead-screw has a pitch of 1.5mm. Then 1/6 turn of the main spindle give you 1/6 turn on the lead screw which means 0.25mm in this example. If you want to mark the position for six holes, then just make a small scratch at the work-piece with the cutting tool at 0mm, 0.25mm, 0.5mm, …, and 1.25mm. The same goes for three markings and so on. It works pretty well and can be handy for multi-emitter lights if you don’t have a rotary table.

That’s an interesting way. I’ve never heard of it.

I ordered up one of these cheapy tacho’s and stuck it to the lathe tonight. It was just a temporary thing to see it work as I haven’t decided on final placement of it. I don’t want to fix it permanently and then have to move it when I get around to making an indexing wheel at the back of the spindle. It’s powered by the 2x 18650’s in the pic. At low mid and high revs it seemed to fluctuate up to 10 rpm. I’m good with that, so long as it’s within cooee. I’m starting to get a feel for speeds and feeds on aluminium now but this tacho would have really helped when I first got the lathe.



There’s a light on the back of the sensor that flashes with every passing of the magnet

stumbled across this on YouTube ,drilling light gauge metal

Nice trick ltp.

That’s neat, I usually clamp it between wood blocks and drill through everything. Hole saws tend to wobble and the wood stabilizes the cut before the metal is reached. My drill press won’t spin nearly that slowly.

I came across this. He does a pretty rough job but it seems to work.

thanks pp, surprised the sander didn’t burn out but.
I think i’m building one ,shooters use corn meal and other stuff on brass shells,
be worth a google, would have to be careful on aluminum
