Good evening,

I hope someone can point me in the right direction. I'm in the process of building (attempting) a mainspring barrel removal device. The challenge being to build it as cheap and safe as possible.

I've looked for ready made mainspring barrel sleeve's The ones I've found are really expensive and I can't really justify the cost. I've read about hole saws with the teeth ground down and using copper pipe adaptors being used. Are either of these practical and safe? If they are does anyone have details of the sizes they used? 

Here's a couple of photos of the progress so far. Still need to determine the size of the axle which is dependent on the solution for the sleeves.

I need to rebuild the clamp as I'm not happy with the holes aren't straight and I'll to get some wing nuts

Thanks in advance

Hi.  What you are attempting  has already been done by may from the plans put forward by Joe Collins.  If you look up mainspring winder by Joe Collins you may still be able to get hold of the plans and other information;.  Initiall builds for 400 day clocks they have bee adapted for all types of clocks except fusee clocks which have a very powerful spring.

i have built  two of these and another in metal under construction as time permits. Regarding the spring retainers , I tried several DIY versions but in the end bough5 ready made ones as they are quite strong.

I have a set of unused ones that I would sell they owe me £40 so that plus postage if interested I will post pictures.

Thanks Watchweasol. Good to hear feedback on the sleeves, and your confirming my thoughts as to purchasing ready made ones.

I've seen a number of videos of varying quality and trawled the interweb, again seeing similar but not a whole lot on the type of sleeve. The Joe Collins lead did bring up a picture of a winder using a hole saw, I may go down this route yet.

I'm not tackling 400 day or Fusee springs, just the ones on my Westminster chime Haller movement.

Dell, thanks for the offer if you have any pictures and dimensions that would be most useful.

Thanks both.

Hi @Neverenoughwatches still here been a bit busy, got problems with a regulator getting the beat right the escapement jewels ( both steel) are a different shape on the face . I can get it running but I am not happy.  All ok here doingg re hab and the like.  How’s your Mum getting along well I hope.

Hi @oldhippy  not tried them on a fusee I think that would be pushing it to its limits. Although the one I made is well screwed together and it’s  mahogany. If well bolted to the bench I guess it would cope, that’s why the mk3 version is still under construction.

you may have read my regulator problem with the pallets, I will post a picture of them for your perusal, I have not seen any like this before so your opinion would be gratefully received.  I will get on the job tomorrow.

Thanks all, I've been checking on and off the Cousins website amongst others for months now and they were never in stock or really expensive. Well what do you know.

    • Righty ho, I re-serviced the chrono module and got a reasonable result with minimal loss of amplitude when not running the chrono and about 30 degrees loss when running. Great. The problem is now that the chrono (and movement) stops running after about a minute or so, a tap on the watch starts it running again. No issues with the movement running when the chrono is stopped. Going to service it yet again, obviously some residual issues with friction in the chrono module (Very frustrating - I wish there was some way of testing it as I go!) I also seem to have a problem with the cannon pinion where the movement is running continuously (with the chrono stopped) but it's losing significant time / stopping. This is one of those two piece ETA style with a driving wheel pressed over the cannon pinion, obviously arranged for driving the chrono module. I had no issues with this prior to service and just added a small amount of grease between the driving wheel and the centre cannon pinion as the technical guide required. What's the best way of tightening these up? I would like to replace it but I guess this is going to be hard to find as it is dedicated to the DD chrono movement. 
    • He uses the micrometer cap, but he leaves the spring out (you can see that in the video). If you leave the spring in, the spindle will move up as well (as shown by @Knebo).
    • Seems like he doesn't have the micrometer cap  attached to the spindle so he can only push down but cannot pull up? If the cap screws into the spindle I guess you don't need the spring? I only have a "normal" Seitz so I really have no idea. 
    • Do you have a part number for the bearing shim lock tool?
    • Yes in my opinion the 3/4HP is plenty but it’s your decision & yes it does come with speed control but foot operation so my reason for changing to potentiometer was because my leg shakes so it was like me revving the lathe & anyway I prefer to set the speed. I & a few others that I recommended the motor to run a Pultra 10mm lathe so if you have a 6 or 8mm B & L then it will be plenty, if you have seen any of my videos you will have seen that when using a graver I run quite slow without any problems.
