Thread: What Did You Do Today 2020
24/06/2020 20:26:12

Ian -

Thank you for showing us progress.

I am following it with particular interest as I own a Myford VM-C too and you might be able to help with a couple of small snags.

The first is that the leadscrew appears to miss a beat now and again. It's an odd effect, as if somehow the leadscrew occasionally saves all its backlash up and releases it in one go, in mid-wind in one direction. Any clues?

The second is one that came with the machine but fell down the priority list, and that is a very stiff quill, making sensitive drilling difficult. The stiffness is enough to prevent the quill springing back up. The problem may be as simple as congealed grease on the rack and pinion, but Myford did not make it particularly accessible. I am also very reluctant to interfere with the wound-up spring. I do not have the tools or knowledge for handling clock-type springs and past experience dictates leaving it well alone in its little housing, still clinging to the shaft! Would I right thinking the rack and pinion are accessible but only by removing the entire unit from the head of the machine?

Hi Nigel,

Firstly I have to tell you that I am not an expert with any piece of machinery, I just knew that although mine is in good nick it was about time to check everything over and adjust or replace as required.

I would think there could be a number of reasons for the table jumping first thing to check is that the gib is correctly adjusted and the table ways are lubricated. From your description it could be a broken or missing section of thread on the lead screw. It could be a particular area of wear that gives out when the load on the thread and half nut is sufficient or it could be an accumulation of wear in the screw and half nuts. Have you tried adjusting the half nuts to see if that helps? If adjusting the half nuts does not fix the problem then it would be best to take the table off and check everything out.

The quill being stiff could just be down to lack of lubrication or miss alignment with the bearings. Maybe it has been stripped and put back incorrectly before you bought it. I would undue but not remove the inspection cover screws, check that there is nothing pushing against the cover before removing it, if it is free moving slip it off and take a peek.

Hope that helps.

Ian

img_20200623_173452.jpgimg_20200623_173411.jpgToday saw the start of a strip down and service of my Myford Mill. Table off to check the lead screw, turns out that it's not too bad at all, a quick tweak of the adjustment screw on the half nut block saw the backlash greatly reduced. The gib seems to be in good condition as well. I have taken out the oil cups in the table to be replaced with new ones, the ways will be cleaned up and checked and the table checked for any little issues before I strip anything further.

Thread: boring head and tools
19/06/2020 21:28:15

Hi,

I did look at rotating the tool within the holder but the cutting geometry isn't correct.

NDIY, yes I did exactly the same thing, even down to the fact that it was a piece of MDF cut out a hole slight larger than the hole I need in the sheet of plastic.

Using the tool held vertical in the holder gives the right geometry but not the required diameter. I think I will need to run up the grinder and see what I can do with a piece of HSS, although for now I have completed the task I initially set out to do so it will have to go onto the list of things to do.

Thanks for all the suggestions.

Hi Martin,

I was thinking about buying a M2 or straight shank so that I could use it in the lathe at some point, but thank you for the suggestion.

Ian.

19/06/2020 18:05:35

Thanks,

Jason is correct, it was the thread on the arbour screwed onto the boring head that was coming loose. Luckily it didn't happen enough to stop me completing the job but I had to take a lot more time than I wanted. I guess I need to look at grinding the two hss tools that I have for the boring head. To be fair the supplied tools were tips brazed onto the shanks and seem to be very well made and it was only the orientation that made things tricky.

Chris B, you could (in fact you have to) raise the work piece above the bed to protect both tool and bed but you still have the same problem and it isn't possible to enter a work piece from below the table (as far as I know ?).

Thanks again,

Ian

Hi,

I recently purchased a boring head from Arc, it has turned out to be a great purchase and has already paid for itself, however I did come across one issue which has puzzled me, as follows.

I wanted to enlarge a hole in a sheet of plastic (perspex I think), the sheet was too large to be held in any way on the lathe cross slide so the mill was the only machine able to perform the task. The problem is that all of the tools that come with the tool are for an anti-clockwise rotation. My mill will and did run in reverse in order to achieve the desired result but I had to take very small cuts to prevent the head unscrewing from the R8 arbour.

Apologies if I have been a muppet but am I missing something here?

Thread: Chester lathe as my new lathe anyone

Hopper I am with you on that and we might also be able to sort out any concerns that he has, unless of course they are genuine short comings with the lathe.

All I can say is wow i wouldn't recommend them after finally buying my lathe from then think I made bad choice

Hi Jack,

Your update is a bit vague, which company did you buy from in the end and what problems have you encountered?

Ian

Do we need another company bashing thread?

Asking someone what they found wrong with their new purchase is company bashing?? If you read all of the thread you will see both positive and negative remarks about several companies. In the mean time it might be that we can help Jack sort out whatever the perceived issues are. I have a Chester DB10 that needed a lot of fettling but now it is a very good lathe with real accuracy.

Thanks for replying Neil and Berty, sorry for my impatience, it has just arrived this morning embarrassed.

Thread: Coronavirus
27/05/2020 18:28:06

One thing I have seen for myself is that this virus seems to be very infectious it infects people so easily, the other thing I have seen is that the outcome will vary a great deal. The general health of the newly infected person does make some difference, as do other factors such as gender and general fitness level, it also seems to be more serious for non European people and of course some elderly people.

I would agree that we are a long way away from breathing a sigh of relief, this is the time the virus will catch those that believe that it is safe to go back to doing normal things and that could cause a second wave or spike in the reported cases.

Has anybody else not yet received Junes magazine? I know a few people that have got there June mag already but I have not received mine?

Just a quick update.

I have been pulled back from the front line at my hospital. It has been a very demanding and stressful period but I have been lucky and am currently healthy and able to post this message.

I would like to express my gratitude to all of those that passed on messages of support, it really does make it easier knowing that people are grateful for the work being done. I just hope that there will be no further spikes or prolonged cases of covid 19 and wish all of you good health.

Thread: Bumblebee behaviour
26/05/2020 22:18:42

Thank you speedy, I am not interested in making or taking honey, I just have a fondness for bee's that I can't explain, I will do anything I can to help them out, I have lots in and out of the garden so hopefully a couple of these bamboo type things will help em out.

23/05/2020 16:02:22

I love bees, but I don't know enough to consider keeping them, also when I looked on line the cost of a hive is pretty steep.

Am I right in thinking I will be helping out by just hanging some of those bamboo looking things up which wild bees will then use?

Thread: Chalking files
17/05/2020 16:45:59

If my memory serves me correctly (and it may well not do) I was taught that only course files should be used on soft material and then to use a strip of emery cloth supported by the file, getting less course as nearing the correct size. I do remember using chalk but I am almost sure that was when draw filling, but I might be talking out of the wrong end, it was a long time ago.

Thread: boxford model c
11/05/2020 20:42:31

Thanks for the replies, that would explain the nipples being full of grease then.

I will re-grease the spindle bearings and use oil on all the other parts, once again, many thanks.

Ian

10/05/2020 21:31:07

Hi,

Can I just ask for some advice regarding maintaining my Boxford model c and keeping it in good condition.

I was of the opinion that the lubricating nipples were there to get oil into the various bearings. I recently tried to inject some oil into the nipples to ensure everything was ok, however the nipples appeared to be blocked, so I unscrewed the main the nipples in the head and discovered they were full of grease.

So do I use grease or oil to lubricate the main bearings and the counter shaft bearings?

Brilliant it is still imported, my order will go out this evening.

Thanks John.

One of my favourites was a chewing gum, I can't remember the name of it but, the chewing gum itself was pink in an oblong shape and tasted hot and maybe cinamon? The wrapper was red.

If it was pink it could have been Dentyne or Big Red.

John.

John your bang on mate, it was Dentyne, now you have named it I remember it, lovely stuff, must google and see if it's still available.
