- Workshop Talk - Lathe Centering Roller Tool 2 - Hints & Tips
Just for interests sake again after I've been asked a bit about a video I did some years ago, here's a better explanation of how I quickly center up small pieces of offcuts. Not saying this is how anyone else should do it, but it works accurately for most of the work that I do. It doesn't replace your Mitutoyo dial indicator for super accurate work, but as I say in the video its quick. Hopefully this answers in detail all the questions, if not please don't hesitate to yell out and I'll help anyway I can.

That's a very handy item to have as I'm the same and loathe to throw away even the smallest piece of metal.
Thank you, appreciate the comment .
Hi Jim. I made one of those years ago. You can also simply use the back of the cutter with the spindle in reverse. That ball race tool can also be used for burnishing, if you want to do that. I'm not a fan of burnishing, but it will do the job, usually with some harmonic pattern in it. Cheers Rob
G'day Rob, someone mentioned burnishing as well so I gave it ago on aluminium and didn't like what it did. Having so many small (sometimes slivers) of offcuts I find the bearing easy to use and quick. I really want to make something like I've seen now on a few vids where guys use a cutting tap in a holder to put/cut grooves in pulleys. It would be so handy to be able to do that for small steam engine pulleys that suffer a lot from belt slip because they are smooth. Have you seen that method or better still ever done it yourself Rob?
@@SteamEngines-Jim Hi Jim. No, I've not made "V" belt pulleys that way or seen any in use like that. I usually make pulleys using a 35 degree indexable carbide tip. This is narrow enough to allow machining of any width "V" belt angle ( usually 38 - 40 degrees). I've never tried burnishing aluminium, only steel and brass, which both will work harden. Cheers Rob
@@Xynudu G'day Rob, I'm only using 2mm or 3mm O ring for belting on my small pulley wheels that I machine up for my models engines and slippage under load is always a problem. I'd like to set myself up to do this -

@@SteamEngines-Jim OK I have seen that done before. Should be pretty easy. Not sure how it will go regarding slippage, but worth a try. "O" rings are quite slippery and stiff. You would be better off buying an assorted pack of small drive belts (for CD players, etc) as these usually include a range of sizes in flat and round, made from grippy highly flexible rubber/polyester. Very cheap and don't slip. Cheers Rob
@@Xynudu Just made the parts Rob, busy now till Monday morning till I can give it a go. Fingers crossed it works.....Need to chat with you next week about 'Best bang for buck Aussie Lathe' ....my eldest son wants to buy a hobby sized lathe around the size of yours and mine. Wondering what you recommend now. Have a great weekend Rob.
Been using one of those for years Jim. A brilliant little tool and really useful. Cheers, Alan.
I did the original video around 8 years ago and got some questions, but the last 3-4 weeks I've been getting queries and if I could do more of an explanation. I use this on a daily basis.
Thanks for the video.
I,am enjoying your channel.
Do have videos of you making things on your lathe, if not I think they would be popular.
Thanks. Ian T.
G'day Ian and thanks for the comment. If you have a look through some of my vids you'll find some things. I don't have the skillset to make an engine from scratch to going, but I'm pretty ok at modifying and adding to engines and accessories. Here's a few vids -

Cheers,

Very helpful
I use mine on a daily basis as I'm always using small bits and pieces (those bit and pieces we never throw away).
great tip Jim👍👍👍👍👍👍

Thanks Kev, much appreciated as always.
Just one question is it important to keep the bearing surface really clean of swarf?
You will hear if there is any swarf by the sound of it going around the bearing, Best to keep the surface of the bearing and the surface of the chucked piece clean of anything.
@@SteamEngines-Jim Thank you
@@lancekennedy3712 You're welcome
Do you have any suggestions for a first model engine?
I mean steam engine
G'day.....a Wobbler is a really good first model to make. Here's a link -

If you're skills are more advanced than that these kits from Bengs are good -

@@SteamEngines-Jim thanks for the suggestions
@@masonatorgaming669Sorry...do you mean what brand of model steam engine to start with (a ready to run engine)? What country are you in?
I'm from the planet Jupiter
