Lathe Sensitive drilling attachment

Been needing to make one of these for around fifteen years! Cant put it off any longer.
Its a little bit of drill tooling that allows you to drill micro sized holes with lathe that is a bit brutal to do that normally.
In the dim and distant past I had a small Hobbymat lathe that was fine drilling very small holes my current ( 25years) 6 inch centre height machine is just to insensitive to drill holes in the sub 1mm size. Hence this little attachment. it basically allows you to push the drill through the work by hand.
Works well and is really simple to make only took me a day someone who knows what they are doing could easily make one in a couple of hours start to finish.
Hope you enjoy me hamming this up.
Cheers.

Keep it up Sir, that was awesome

[@CazualHaze]

Thanks, will do!

Four comments: 1. Nice result 2. Watchmakers make an accurate small centre using a graver 3. This video gives a good illustration of one advantage of a box of gears over a Norton-style gearbox, namely versatility. With the Norton system you are stuck with what the lathe manufacturer provided whereas with a box of gears you can assemble them with much more versatility. The 3-hour fiddle on this job easily absorbs the time needed to calculate and assemble the gear train for a "special". 4. Measure twice, ... 😉

Russell thanks for the comments. I do wonder whether in our new cnc world that a hybrid lathe would be the bees knees! If you could use hand wheels as normal but they control steppers. Add an encoder to the spindle and you have a manual cnc! Cheers

[@russelldold4827]

@@CazualHaze I like your concept, and the technology certainly exists. Unfortunately as a retiree the necessary bits&pieces are beyond my budget, but no matter, I can achieve what I want with the manual machinery I have. Thanks for the effort you put into your videos.

@@CazualHaze pretty much what I use at work, can be run as a manual lathe or full cnc , or any combination of the two

Since Knurling "Displaces" material, you probably could have avoided using the super glue by putting a "Straight" knurl on the steel tenon. Wakodahatchee Chris

[@CazualHaze]

Absolutely, however I don't have any straight knurls.it is what it is. Cheers

Great job

[@blc6464]

Thanks good job!

[@CazualHaze]

Thank you too!

[@homemadetools]

Good work yet again. We posted this video on our homemade tools forum this week :)

[@CazualHaze]

Awesome! Thank you!

On the 3D printing front, consider changing to 0.6mm nozzles and a modern slicer (say Prusa slicer). The improvement is significant.

[@CazualHaze]

@HeathLedgersChemist Thanks I will give it a go I have some stuff I need to print, be interesting to compare. Cheers

This is useful information for me, I'm needing to drill some fairly small holes (small for me, about 0.030 inches), thanks for posting this.

[@CazualHaze]

Glad it was helpful!

I guess im randomly asking but does any of you know a tool to get back into an Instagram account..? I somehow lost the account password. I love any tips you can give me

@Callum Emery Instablaster =)

[@callumemery1542]

@Edwin Jordy thanks for your reply. I found the site through google and I'm in the hacking process atm. Looks like it's gonna take quite some time so I will reply here later when my account password hopefully is recovered.

[@callumemery1542]

@Edwin Jordy it worked and I finally got access to my account again. Im so happy! Thank you so much, you saved my ass !

Interesting Video, I may make something similar for my Hobbymat MD 65 as even with my small ROHM chuck anything smaller than 0.6mm is a bit hard to chuck and tends to slip even though it should go down to 1/64" (0.40mm). On that point at the end you showed a No 80 drill against the hole you had drilled which you said was 0.40mm... The No 80 (0.34mm - 0.0135") looked way smaller than the drilled hole and not just 0.06mm difference, are you sure you drilled a 0.4mm hole in the silver steel?

[@CazualHaze]

Go for it! I do think its worth the effort. I am not sure now what holes I drilled I am also pretty bad at putting these small drills back in the right hole in the box! My first lathe was a Hobbymat MD65 I built an entire Tich 3.5inch loco with it and the Hobbymat mill. Great small lathe. Cheers

[@olegf8805]

I am using a tube adapter. There is a chamfer on the end of the tube. She rests on the workpiece and centers the drill.

[@CazualHaze]

That sounds an interesting solution.

[@olegf8805]

@@CazualHaze I work with small shafts 0.2 - 1.5. Perhaps for large diameters it is difficult. Tell me, is your collet in the video, is it similar to the ER collets that are made in China?

[@CazualHaze]

@Oleg F The chuck is a three jaw miniature Jacobs type chuck. I think it came from a Dremel type tool made by Black and Decker here in the UK. The tool burnt out but the chuck was worth keeping. There are small chucks out there that would be good for this-www.chronos.ltd.uk/product/high-precision-small-drill-chuck-0-4-mm/ Cheers

[@campbellmorrison8540]

Love your work but if you were going to bore it out why bother going to an equally ME thread why not a metric fine etc. I guess you use what you have and you are only making one so why not :)

[@CazualHaze]

Hi, thanks for the comment. You are spot on I made the thread with what I had, those taps and dies are expensive. With lockdown and no rallies model shows etc its not easy to find quality bits at reasonable prices. Best Cazual Haze

[@AdaptingCamera]

I don't understand why you use that thing to measure the thread. It's fun, but complicated. Much better to buy a set of thread gauges for mm and inch, and that will show you clearly and exactly the thread dimension. First later on you pick up the thread gauge...

[@CazualHaze]

Hi Adapting Camera, I dont have thread wires, like so many things its on the list! The comparator is a useful bit of kit and only cost scrap money, it is however big takes up a lot of space!! Cheers

[@AdaptingCamera]

@@CazualHaze I don't mean thread wires, but the thread gauge you actually using and mentioning in your video later on kzbin.info/www/bejne/aZjMiIV7otd5ndE BTW, I have a similar (not the same) mini chuck which I also made a lathe attachment for on my DIY lathe. I simply used a micrometer to measure the diameter of the rod and a thread gauge to measure the threads, which happened to be 3/8" 24 pitch UNF thread. It was a simple first project on my DIY lathe converting 30 mm of a 60 mm long 10 mm diameter steel rod into 3/8" and threaded 1" down that part and made it into a perfect mini chuck shank.

[@CazualHaze]

Ah ha I see what you mean Perhaps its time to get another set of thread gauges. Cheers
