Top Night Caps John. I think that you can be immensely proud that you have created an engineering archive over the years that so many of us have learned from. I searched your back catalogue today and watched 'Trouble at Mill' again to look at your DRO installation, as I'm doing my VMC soon. I hope you get to 100,000 soon, you deserve it. On another note, the farm at the bottom of the lane I live on houses a number of steam vehicles. There was a local steam fair on this weekend (Stoke Row) and this evening we were treated to them all returning from there. A number of Fowlers and a Sentinel steam wagon came past the house. Best wishes, Dean in Oxfordshire.

Friggin' right.

John, the power feed shaft has bronze bushings thru the castings on either side of the gear that has the end play you were demonstrating. The bushings are t shaped and the top part of the t on the bushings act as a thrust bearing on the shaft gear (the one with all the play) . You need to make new bushings or fit some shims. The bushing bores may be worn oval as well and there may be wear on the power shaft drive key.

I did that same job on my old '62 Harrison a couple of years back, and it stills runs smooth, years of chipping cleaned off !

Good find, John. Thank you for taking us along for the ride. It's got to be extra tough filming when you're stressed about it, all the backed up projects, the channel, etc. I'd have needed a beer for sure. Anyway, thank you for sharing this, and best of luck to you and yours this week. :)

I came here as stripping down my Harrison but I got as far as you (12.30) and thought I need to go in the house and do some research…thanks as always John.

Useful to us Harrison 140 owners, thanks John.

Really great video John, those annoying little hiccups that occur in our equipment, first we fear the damage , but then the work is very interesting and usually is less than we first feared. Enjoyed, cheers to you and Debs!

I think Mr Crispin on YT showed a basic refurbishment on a similar lathe recently. I know the feeling when a well looked after machine fails. Thanks for sharing.

Always sad when a trusted machine breaks. Good thing there's a mechanic who pissed about in the shop there to repair it. Stay well. Stay safe.

It is satisfying to see the mechanism behind the power feed control I've heard the sound of for a while. Always good when you take something apart expecting total carnage but all you find is interesting!

Wow, you got lucky with that find. I was concerned that either a gear or shaft was worn and causing the problem. Best wishes to you and your loved ones

That bastard chip😁, good work Johnny, like you videos , stay safe

Thanks for the video ,brilliant as ever . Nice to see how that drive works

Ya just can't find a lathe like the ole Harrison's any more !

Any room to fashion a sheet metal cover to deflect swarf from those gears? An adult beverage aluminum/aluminium can might be a good source. You could just discard the contents... maybe into a chilled glass.

My thinking as well, bad idea to build a machine tool with upturned cups of oily moving parts that chips may fall into. I would have expected a little stamped cover there.

Once you hear his breathing down the microphone, it's hard to unhear.

Hello John, Pleased to see there was no major issue... that little bit of maintenance will keep the Harrison going for another 90k subscribers... Take care. Paul,,

Really enjoyed the repair of the diesel head. Always a good bit of useful information. Thanks for your time and skill.

Similar to the M series Harrison lathes. Disconnect the feed shaft and lead screw and the apron comes off. I am glad it wasn't anything too serious. I am surprised the apron does not have its own oil supply sump.

I reckon that lathe will outlast all of us.

Especially if a little clot in the works ends up in a heart attack :)

Nice one John. Got to my gib strip screws and been putting it off due to stripping the saddle

Good video John! that's why I never use compressed air to blow the crap away on my machine tools, simply because it gets where it shouldn't be and causes problems. Thanks for sharing

Thanks for the video John.

Thanks John

Nice simple fix. Nice job John 👍

Nice to see it wasn't anything major !

Nice work John. Great video. Thank you for sharing.

Good work, pleased to see you got to the bottom of it.

Cheers John well done on the 90k All the best.

Thanks for sharing 👍

It's good you tore it down John so you can give it a good Kerosene bath and put it all back together fresh. Congrats on finding the issue. Ricko

Great videos as usual john thanks .

Great video John, keep'um coming..

When you were trying to separate the apron from the saddle, I was saying "put some support under the apron, or you'll bend the feed shafts, when you release the skirt".

Evening. I've been in there recently on my 140. Mate . There is another bolt ,setscrew under the saddle \ apron top that is holding it on .took me hours to find ,then top comes off.i wanted to know my ways were Clean before new wipers . I went in there because half nuts were very tight ,just needed strip , clean ,lube , all good now. Very hard to engage screw cut before.

Hi John, brilliant video, I've got to shift an L5 next weekend and im going to have to strip it to move it, the apron looks identical to yours and I presume it'll come apart the same way. Do the lead screw and power feed just pull out of the gearbox or are they held in place with pins or something. Thanks, Tom.

as per brill

Well John sorry it happened to you but I'm glad as I have the same issue and now know how to split it down, on a side note if you have any idea where I can get new set of halfnuts from that would be appreciated. I do look on ebay just never seen any for sale. Keep up the good work and I hope your dog doesn't bite you again😁

Great John nothing major 👍👨🏻‍🏭

When the lathe plays up we always imagine the worst. Good it wasn’t anything serious.

check out Max Grant ,The Swan Valley Machine Shop ........he makes a cover to keep all the crap out of the gears.i copied his idea for my lathe .made out of a bit of scrap sheet metal.

Atleastu found something John it's when u strip it and Find f&£k all wrong it's annoying 😣

Glad it was minor!
