I have a similar knurling tool Rob but I only have one set of wheels. Now I know how easy it is to change them out I must get some more! 👍👍 Cheers, Alan.
It always amazes me how those small run away parts always finish up in the MOST unlikely places. Almost like someone is deliberately making life hard for you ;) Divine intervention for machinists ? Cheers Rob
Hi Rob, I have determined (through a lot of practical experience and discussions with other like minded men with workshops) that ALL men’s workshops have a “Time Dilated Black Hole” or TDBH for short. Have you ever noticed how you drop something and it rolled into a spot in your workshop and no matter how long you look for it, even though you know EXACTLY where had fallen, rolled or bounced to it cannot be found........AND then several hours/ days/ months or even years later you look in that same spot and there is that “missing piece”. Well now you know that it fell into that TDBH and returned at some random time - still waiting to see if I can find that part even before I dropped it......now wouldn’t that be cool! Cheers - from the other side of the TDBH. Bill
You might be on to something there Bill. I just hope my lathe doesn't get sucked into a time vortex and disappear. I would have to buy a new one then. LOL Cheers Rob
My knurling tool has the alternate design you mentioned with the pins held in by circlips. This is easy to replace the wheels, but it is very handy to have additional circlips on hand. They can either break or fly off to unknown places on the floor, both of which happen to me. Dave.
Circlips always annoy me. Mainly because I never seem to have the correct sized pliers for it or they don't grip properly or they shoot off somewhere. The splines setup seems a bit crude, but so far it's held up OK over 20 years. I guess it does the job. Cheers Rob
Hi Rob,. I would like to see you do some knurling on stainless steel. It would be good to see it done by someone who knows what they are doing. I could not believe my eyes when that stainless started to change and then start spitting out. Was glad to see what the problem was. Sure was nice to have an old neighbor like that. I too have an old neighbor and lots of enjoyable times with him. Anyway look forward to seeing how that knurling works out on stainless. Thanks Dale in Canada
Thanks, Rob! Another tip for newbies: Changing over the lo-profile allen head screws in the scissor arms would get you an extra few mm of chuck clearance, and the first jaw hitting the allen head might skip over the domed head instead of an "insta-jam" into the thread ends & nuts. Sorry to deliver yet another smart-a55 comment - I know it's a rotten job - but then someone's gotta do it! :-) Cheers! DIYSwede
Hi Johan, the major clearance issue will be right at the roller pin ends. The pivot bolts for the arms are well back from the action and not likely to get in the way. Cheers Rob
If your knurling tool pins have circlips, you can use the nut trick to knock out the pin AND also to give it clearance when you put it back. Cheers Rob
Hi Rob, Interesting video... Clearly you've knurling on the mind at the moment... Are you going to find some stainless steel to have another go at knurling that? Keep the video's coming. Cheers Paul,,
Hi Paul, I've changed tack on the screwdriver refurbish and am now using some chrome moly from a scrap wheel brace handle. I don't have any other stainless steel the right size and would have to waste a lot to do the job, so this is plan B. I am undecided if it is worth a video. Probably not. Cheers Rob

Good move. Cheers Rob
Nice vid. Anything to keep us old guys from crawling around on the shop floor! 😊 - Mark

Same style knurling tool but with circlips. I will be using the nut trick.
Great tip. Thanks Rob
Glad you found it useful Roy. Keeps the oily pin clean and stops it getting lost in the process. Cheers Rob

Thanks for the great information I did not know how to change the wheels
Added to my lathe knurledge. Many thanks!

Hi Dale, I will have another go when I get a chance. Cheers Rob
Thanks for the tip it will come in handy never changed mine but nice to know how if i buy new wheels

Simple but if one didn’t know about the splines on one side it could cause problems.
Yes, the pins can only come out from the spline side of the arms.
