Sorry, Iam late. I have been following your videos recently, but have only now discoverd this older one here. Great idea, great explanation, will make one (have just ordered the tyre depth gauge). Thank for showing this (and for the detailed explanations on your blog).
Yes, it has a time out function as well. Basically it uses the same design/head function as a caliper. I have found this to be a nuisance a few times, but generally you only use the gauge to finish a job, or while doing a fairly continual action like milling, so you are not holding a continuous static reading for extended periods like a fully dedicated DRO. Cheers Rob.
Wow. This is a great idea. Thanks for the share. I know what I will be ordering in the next few days..lol. been itching for something like this for the lathe, mill, and shaper
I have one of these units, and wondered what I could use it for and you have given me the answer! Well done, I think this is a brilliant idea. My only comment on the build is, would it not have been possible provide holes through carrier to give access to the fixing screws for future dismantling? I know you say they are cheap to replace but I am addicted to saving everything. I look forward to your next innovation.
The tyre tread depth gauges are widely available from Ebay. You can easily have a look. Also sellers come and go, and I don't want to be seen to support any one company. This is not a commercial web channel - it's purely casual user territory. Rob
Great idea -thanks for posting -- Instead of putting a spring -maybe glue a small weak magnet to the end of the plunger that will hold plunger to to cross slide--
Hi, It is a great idea, does the car tire readout have the usual calipers' time out. That is it will switch itself off if not used for some time. Once I fixed a digital caliper to my mill and this was so frustrating that I had to remove it. Thanks
Thanks for the video. The link you give for making this DRO is no longer valid. Think you could do a quick explanation of how you arranged springs for the probe? It looks like a much better system than a magnet, since it can be used with non-ferrous contact points.
Hey Rob, Regarding the timeout with the display, after this when the on button is pressed again, does it show the same reading as before it timed out or does it come back on zeroed out. My black cheapy $10 6" verniers come back on with the previous reading and I was hoping these little tyre gauges do also. If they do I will be buying 2 as I have been thinking about buying a couple of the cheapy veriers to mod for a while now. How do you think one would go hacking up 2 sets of the 10 buck 6"vernier calipers to do a similar thing, but achieve greater range? That's got me thinking now, Hhmmmmmmmm (stand back everybody, unless you want brain bits all over you)
djpaulk No steam engines here yet, but would like to find the time. Watched the video and was greatly impressed. A beautiful job, and no visible runout. The machining job must be good. Thanks for sharing. Cheers Rob
xynudu Thanks Rob :) The flywheel is a bronze casting and it has a steel rim fitted. It was a heat the metal rim on the lathes faceplate and put the bronze flywheel in the freezer job. Then run out to the lathe with frozen flywheel in hand like a madman and she shrunk fit nicely. I then turned to final dimension and bored hole for the shaft. I spent some time on this part and there is no visible runout on the flywheel. I learnt from past engines that a wonky flywheel can detract from an otherwise beautiful engine, so there was to be no stuffups on this one.
Well I thought I would give it a go anyways and I bought 1, identical in appearance as your silver tread depth gauge and my one powers back on at the previous reading after a time out.. So either you lucked out or I lucked in? Either way I'm pretty happy with that for 6 clams. It will now become a handy dandy lil dro :) Yes, you said no "steam" engines here yet, but you should have mentioned your flamelicker! I knew I remembered hearing you mention some sort of model engine. You had me thinking I was loosing my memory :D Now the cat is out of the bag you're going to have to show us!.. Paul
I get a lot of requests for these and also gears, but unfortunately I don't have the time, and it would also be uneconomic for me to do it. It is essentially a DIY hobby project. Cheers Rob
I made mine on the lathe. You need a vertical mill slide, which Myford do make/have for you machine. Good opportunity to try milling on your lathe. It works very well. Cheers Rob

Thanks for the feedback. It's a very handy little item for fine lathe work.

Super useful Craig. I'm surprised they don't make something compact and cheap like this. Gets a lot of use, especially for carriage travel. Cheers Rob

No problem man..I understand. I may try to tackle it soon.
Very nice and simple Mr rob,
Just one question :
How you connect the rod to the bed ?
Thanks
You don't. The probe is spring loaded and presses against the lathe. All explained in the web page link in the description. Cheers Rob
@@Xynudu oh yes I saw it .
It's Frist time i See spring on caliper!
Thank you again Mr rob 👍
Great idea -thanks for posting --
Instead of putting a spring -maybe glue a small weak magnet to the end of the plunger that will hold plunger to to cross slide--
Yes people have done that and it works OK. Cheers Rob.

Hi James. The link in the description should work. Try the one below: users.tpg.com.au/agnet/microdro2.html
The web page link fully describes how to make it. Rob
Brilliant design, I bought one to modify. I've cobbled together something with a caliper meanwhile that works.

Do you sell those? I would like to have one for the X and the Z direction on my Myford Super 7
No. These are purely projects for home hobbyists. Rob
legend!
Where can this cross slide vernier be bought ??
You have to make it yourself.
Here's how: users.tpg.com.au/agnet/microdro2.html
does your depth gauge have a spring..?? how do u make the needle slide out..
Yes. Go to the web design page: users.tpg.com.au/agnet/microdro2.html
thank you.
Noticed at 1min 15 ish the slide moves before the readout, can you check.
Jonny: it is backlash from gears. The measuring tool has an accuracy of 0.01 mm.

djpaulk It comes back zero'd out. So, looks like you wont be buying any ;) Cheers Rob

Shame it cant half the actual travel, plunge in 1mm its taking 2mm off diameter.
Decent idea though.
Turn your compound to 60⁰
Very nice gadget xynudu.....you wouldn't consider making one of these little creatures for someone for a fee would ya??? ;)
I get a lot of requests for these and also gears, but unfortunately I don't have the time, and it would also be uneconomic for me to do it. It is essentially a DIY hobby project. Cheers Rob
Just too bad! I have no way to make the base!
