Slow progress. I've been busy with the mower and other things. The cover is all stripped now, it was a nightmare. I'm getting a bit of a method going to get it clear quickly. I've decided I'm going to paint the inside of this, and the gears that are covered by it, red. While keeping the outside grey. It will hardly ever be seen, but I want some red on it somewhere! More mower work to be done. I'll probably strip the tailstock next as that'll be a nice section to do. The wheels in the background are the 4 wheels that make up the mowers seats roller, took ages to clean all 4 of them and to get them ready to paint, now they're the nice ransomes green. Looking forward to this week's video Phil! Edited By Richard Kirkman 1 on 19/06/2020 21:09:19 |

I've not been very busy the last few days with the lathe. I've been working on the mower and a really fancy bowl Anyway, I decided to strip another piece of the lathe today I will take off the machine tag at some point And I flattened the primer on the headstock cover, so it'll get another coat of primer when I get around to it. I need to start spraying the primer so it goes on more evenly I'm struggling with stripping the paint from parts. The stripper leaves a very stubborn gooey mess behind which is tricky to remove. Are there any tips or tricks to help it go a bit better? Or a better type of stripper? |

Thanks, Herman, The sander did receive inspiration from various articles online, but not plans as such. Maybe that's the issue, I still can't drive so I don't have a car! Take a look at this, probably RAL3001 or similar |

Looking good. What primer are you using? Anywhere I can see what your woodwork looks like? It's just the tractol red oxide primer that's suitable for the tractol paint I'm using
The link should take you to an album of what I've been up to for the past few years. Not much woodworking since I got the lathe last September. It's taken up a lot of my time. If only I worked as quickly as you, I need to learn your time traveling tricks! |

Another productive day. Still splitting my time between the lawnmower, lathe and woodworking projects. Perhaps I have too much on my plate! I spent some more time cleaning the rest of the paint off of the headstock cover, then I put a coat of primer on it. I'll sand it back then do another coat. It'll be better to paint everything at once with the sprayer, so I'll wait to do proper coats. I sanded back the filler fully, then put a bit of silicone on the seal and spread it around. Then I used it in with a socket. It went in very easily. Just waiting for the other seal to arrive then I'll install that too. Then I worked on fitting the new light switch. It didn't fit in the same hole as the last switch, but a quick bit if chiseling later, and it fit snugly. I'm very happy with it, much more fitting than the red switch The lathe is currently in as many pieces as it ever has. So I started stripping the few parts that were already off that need to be repainted Stripped and wire brushed, ready for some primer at some point!

Thanks for the photos. So there is a sleeve in the flange and in the sleeve the shear pin fits? So this sleeve is peened into place?
Paint stripper ... and that is how the journey starts ... ask Phil and myself! All the best, see you in next year Yes I do believe that there is a sleeve there. See the pictures. I suppose you could just make it from one piece if you had a lathe and some aluminium. I know exactly where this journey is going, and it's a slippery slope that descends into madness! (For me at least. I'll have to get a compressor and spray paint it properly, unless I can get the hvlp sprayer to work better and stop throwing out chunks) Once the lathes complete I'll need to find another old machine to restore... Next year will be here before you know it Edited By Richard Kirkman 1 on 12/06/2020 22:53:56 |

Some progress today, the filler, the brake oil seal and the toggle switch arrived. So looks like we get post twice a week these days. I made a silly decision to try some paint stripper on the headstock cover piece, so now it looks like i'l have to paint it properly. And If i'm painting one piece, I may as well paint a few more. And if I'm painting a few more, I may as well paint the whole lathe... Another can of worms opened I'll have to get the lawnmower done first I think. Otherwise there's not enough space for parts and cleaning. It has been stripped completely, but not photographed. It had more layers than I was expecting. Thinner in some places than others, so its been repainted when the old paint wore through, but the top grey is not very thick at all. Pictures for Herman It's peined over on one side so it won't come out. It could possibly be made a bit longer, but it works fine I think Then I mixed up some filler. I didn't need much but I had to make a little bit as I was unsure about mixing, but It hardened nicely. I've sanded it down, I'll fit the seal tomorrow. |
11/06/2020 22:16:23 |
I'll take lots of pictures tomorrow The O ring is on the lever shaft. It seals fine so I'm not going to bother to replace it |
11/06/2020 21:59:40 |
The shear pin seems to have a collar that it fits into, possibly of some harder steel so the rest of the shaft can be made softer. I'll measure what's there tomorrow. I still don't know why there would have been a shear pin lodged in there. The leather seal I made was such a tight fit it would not have gone on if I had put tape on it. It doesn't matter too much since it's unlikely to leak anyway as there is an O-ring on the shaft too. It's just a really cheap wood lathe. I've been turning wood almost 4 years now, mainly wooden bowls. The brand is nutool. |

Another productive day! Firstly, I decided to replace the spade connector, which went okay. Nothing new, just strip and crimp. Caps will be replaced as soon as they arrive. Don't know when that will be. It seems to me that we only get post once a week these days. Then I went and picked up the circlip pliers. The circlip wasn't easy to remove, but I managed eventually. Then the shaft just slid out quite nicely. Pretty messy inside. Initially when I took this to pieces last time, I tried to clean up the inside of this through the slot at the bottom. i found some pins inside and I had no idea where they came from. Thinking about this more today, 3 months later, They must have been spare shear pins, but why on earth would they have been stuck up there with loads of gunk? Judging by the quality of the seal it can't have done it any good. That's the pin I found in the pic below. But after I removed out the old seal. I managed to get the seal out without cutting into the shaft this time. I just drilled it and punched it till it came out. Quite easy The shaft came out quite easily but there was no sign of a gasket. Every other place has had a gasket in, but this one doesn't. It wasn't leaking, but I've made a gasket anyway, It can't harm. Since I had access, I removed the forward reverse lever. It wasn't leaking but I thought i'd replace the leather gasket since I can't harm and I can make one tighter. Same as the last one, Glued to a bit of wood, then turned by hand It fits really nicely, much tighter than the last. Then I polished the shaft where the new oil seal is going to go. I measured it to be 1 1/16 inside, 1 5/8 outside, 5/16ths thick so a new one that size has been ordered. Exactly the size you said Herman! I would have loved to submit a picture for the cover, but my lathe isn't exactly in pieces to take a picture of, or painted nicely! Back to waiting for parts to arrive. So I'm making some drawers and working on the lawnmower |

Unfortunately, the circlip pliers didn't fit so I'll have to wait. Meanwhile, the threading gearbox sight glass leaned up very well, although the paint from the words disappeared. As you can see, it was cleaner than the headstock one, but now they're both fully clear. Or at least as clean as I want to get them. Then I did a second coat of paint on the wall. The wall now reflects the light much better, and it's the wall that the lathe sits against, so it's a big improvement. I can't have a white backsplash like Phil, so i'll make do with a white wall! Now we're just back to waiting for parts to arrive... The caps are past their delivery date, so I expect them any day now. As is the toggle switch. I have the new spade connectors but I'll wait till the wall has dried so I can tidy everything up |

I would definitely fix the casting. You need even pressure on the flange to get a good seal. You can either braze it or use metal epoxy. Me? I would use metal epoxy as these days the resulting material is better than the old steels. Yes, the second seal I mentioned is inside this bearing. There is no bearing. The cast iron flanged unit is the bearing. Good work on the sight glass! Thanks, Herman I should be eventually getting a replacement flange, so I haven't bothered with trying to fix it. I'm not sure epoxy would be strong enough since the countersunk head has been pulled through, so it would need to be strong. Hopefully, I'll get the part. Your explanation about the spinning oil grove makes a lot of sense so thank you again. The circlip pliers are not going to be here today, so my dad borrowed some from work, hopefully, I'll be able to make them work.

Fantastic progress today, I'm very satisfied with what I've done I began by moving the lathe away from the wall and starting to remove the main spindle. It must be the 4th or 5th time I've taken it out now, so it was very easy. Side note, Phil and Herman. If you decide to use the nitrile rubber gasket material you should know that it creates a very tight seal, almost sticks the two faces together, so it was a little bit of a struggle to get the parts off. But well worth the effort for it to not leak Anyway, as I was taking it to pieces I saw the usual leaking spots. It drips out from below here, however, this could also be leaking from the main spindle where the casting is broken. Either way, I need to replace the gasket Looking at the back bearing cover housing there is definitely space for a ring of some sort to be placed, and there are grooves in the main spindle too. I am sure there must be some sort of seal here too since a little oil leaks out. But I can't find anything in the manual about it. Thoughts??? Then I proceeded to remove everything else. I blocked the bottom hole of the sight glass with a rag, then I used a pipette to repeatedly fill it with glass cleaner. I managed to find some pipe cleaners in my grandpa's old toolbox so that was a great help. It was tricky, but maneuvering them inside helped to clean it out. I let it sit, then cleaned, then filed it back up and let it sit many times. And I am very pleased with the result. Looking closely it seems like there is a crack on the inside of the glass, or maybe a scratch, but it doesn't go all the way through and I'm not quite sure how it got there, so I'll leave it. Then I moved onto the removal of the forward-reverse spindle. This stopped pretty quickly since its held in by a circlip which I need 90-degree circlip pliers for, but I only have straight ones. So I'm stuck for now, however, I have ordered some. Click and collect from Screwfix so they'll be ready soon I hope. Looking at the manual of the lathe, there is a bearing and an oil seal on this shaft, so I will replace both. This means ordering more parts and waiting a while, so I will take the threading gear box to pieces again and clean the sight glass in there the same way. I'll also take the tumbler arm off again and put that back on properly since after I played with it it has started leaking a little. While I was waiting between the sight glass marinading I painted the wall behind the lathe white. I'll do a second coat tomorrow, but It's looking a lot brighter. It should make lathe work a bit easier. The threaded hole in the headstock used for mounting the splash guard in my lathe has been used for a chuck guard. I don't tend to use the chuck guard as it just gets in the way, So I'll take it off. I will also try to get the splash guard from Tracys lathe and fit it to mine if possible, but postage may be an issue, and that's if she ever gets back to me! Plenty to do |

Thank you Howard, Herman, and Phil. Some valuable insight there. I hadn't considered that the single to double lip would make a difference, but it does make a lot of sense. I think the pictures make the damage look worse than it really is. As for the sight glass, the body filler won't arrive for potentially another week, so I may as well take the spindle out and have a good go at cleaning the sight glass. I need something that I can squirt in that will break up the thick muck, but I'm not sure what would be best. The filler may also come in handy If I want to fix any casting imperfections when I get around to repainting. Still practicing on the traveling steady, I'm almost happy with the finish. Phil, I don't think I have a local nipple shop anyway. I'll just try to keep these ones I'll try putting some window cleaner in and let it sit for a while. I may have some pipe cleaners I could try as well. Oh dear! Now I've just though, if the spindles out maybe I should try to replace the final gasket too. I've opened a can of worms within a can of worms. Still better than being bored! |

Just finished taking the oil seal and shaft back out. Polished the shaft up nicely. It's brighter in person, the camera doesn't quite do it justice. The seal came out quite easily. I would have been tempted to reuse it, but I have ordered another so I'll wait for that. I think it came out so nicely because there was oil in the hole, so it slid easily. Looking in it after you can definitely tell that it leaked through the outside. Although it may have leaked through the shaft as well. The shaft seems to have a little bit of pitting on it, I think it's minor and won't matter, but your thoughts and opinions are welcome as always. It's around where the seal is, so maybe it needs dealing with? I don't particularly know how tight it needs to be. The sight glass definitely needs a good clean, but I can't really get to it without taking the main spindle out. Luckily that's a lot easier for me than it is for Herman! So, I may take the spindle out and give it a go.Undecided yet

I've ordered a new seal, I'll polish it till I can see myself. It'll probably be a week before it arrives. The plus side is I'll have to drain the headstock, so I'll be able to try to clean the sight glass!

Did you polish the shaft that goes through the oil seal before you installed it? It seems it is weeping past the seal on the shaft. Nope, just cleaned with a cloth, no abrasives were used It's coming out through the outer bit. Pretty much where i carved a channel in. Exactly where you told me to fill it and I didn't. I should have listened. I'll fix it If you look carefully in the top right, its definitely leaking from there. That's the exact spot |

I replaced the bearings and the seals. ( and I seem to remember there is a gasket at the rear too). However. I did have the entire headstock stripped at the time. Also I was sick and tired of all the oil leaks everywhere Incidentally, I also bored my wormbox true and bushed it. Action is much more positive now. Yes, I've replaced the gasket already and it's holding fine. It's just the seal that's leaking. Phil, this stuff? |
06/06/2020 17:22:07 |
Looks like I'll try some windshield cleaner, but I'll have to blow it out using a straw with lung pressure! Leaking once again. The brake seemed to stop working so I thought I'd have a check. Low and behold, it's leaking. It seems like its leaking from the outside of the seal, not the inside. So I need to take it out and put it back with gasket sealer or something? What do people recommend? |
05/06/2020 15:30:54 |
Very cool Herman, do you think you'll do something similar? Also, how well did the windshield cleaner work on the sight glasses? I managed to clean mine a bit but they're not as clean as I'd like them to be |
