Platax Question


Don

Recommended Posts

I just noticed a nice looking Platax on the Bay. I don’t need one now, but every time one comes up for sale I watch it. This one has a punch that looks a little strange. It's the top left one in the third photo. Does that look like it belongs? There's nothing in the picture on the box that matches it.

Item 371379556382

Cousins still offer the two smaller removing punches (Bergeon name), they they call them: heeled bush holes. the 1.10mm is in stock and the 0.90mm is suposedly available on the 14th Sept, but I wouldn't rely on that. I wonder which one is missing?

Sorry, Don, after looking again at the Platax tool on eBay, I now can see all three removing punches (they occupy different positions than in my Platax and I stupidly assumed that one was missing). What seems to be missing from the position occupied by the strange punch is the Reducing Sleeve, 2677.3A . But this may well be already installed in the Platax body. If so, then this would be a fine buy as you would have a full Platax set plus the little punch. If the sleeve is missing it could easily be made up out of brass stock - unfortunately Cousins list it as obsolete!

Hey Don,

 

I agree with Colin and Geo, this is not a complete set of punches.

Be patient my friend, a complete set in good condition will come up for sale ... but when it does mate, be sure to pull the trigger on it, as they don't stay up for sale long.

 

Took me about 7 months to find mine, and it came up at the most inconvenient time ... right when I'd saved enough money to buy a Horia 7750-53 Movement holder :rolleyes: so typical.

 

Just as a reference image, this is what you are looking for Don.

I'd still bet money the part is in the tool. Send the seller a message and ask them to unscrew the retaining cap to see if it is there. Even is it is missing, as Colin said in a previous post, it would be really easy to make one.

The biggest problem usually, is the punches can have broken pivots or debris jammed in the ends. If this is the case it is virtually impossible to remove. I was lucky with mine, only one punch was blocked, but I managed to vibrate the pinion out using intense ultrasonic cleaning.

If you do manage to get one, it is a good idea to make a set of plastic caps to fit over the punches when they are not in use. The tips are so fine, that dropping them onto a wood or laminate floor can end up blocking them.

This lookl like it! eBay 252034463500

 

As Geo reports I have extracted a broken pinion with ultrasonic cleaning, also from some of my staking set punches.

That's the one I'd be bidding on my friend

Appears well looked after and complete

Interesting. Thanks, Colin. As I wrote in the OP, I always watch these when they come up for sale, even though I don't need one. The reason is because they are so rare and if someday I do want/need one I may not be able to find it. Granted, that's probably not a great reason to buy a very expensive item. On the other hand, is there a better, safer method of removing a balance staff that doesn't necessitate having a lathe?

 

Does anyone know anything about this Bergeon punch?

Could this be a viable option for removing staffs with my staking set?

 

Thanks,

 

Don

Hi, thought I'd post here to avoid creating more Platax threads:

Can anyone tell me how to best select the correct "catch" / "heeled base" for a given balance assembly and also which punch to use?

I presume you got with the smallest that will fit in each case, but I thought I'd better ask first. My set only has the 0.9mm and 1.0mm heeled bases. 

Thanks.

    • I take it that you're comment re the Unicorn is 'tongue-in-cheek'? Would any of the watches that are on the link I posted be likely to be radium watches? What period was that prevalent in and when did the practice stop?
    • As much as I hate Facebook, can a forum-like place be set up on there? Free and the ownership can be taken over by the next person whenever.
    • I existed before the term mechatronics engineer existed. I had to combine electricity, electronics, pneumatics, hydraulics and computing just to keep my own equipment working. I have never sub contracted any of my own repairs to the suppliers because I know I could do a better job. For a long time, dental suppliers in my country would bring their dead equipment to me that their own engineers cannot handle. I have accidentally embarrassed a couple of hospital heads of engineering by demonstrating their inadequacy.  I think mechatronics is the most under-appreciated, under valued of all the engineering sciences. I had a part-time dental assistant about 25 years ago, who was studying mechatronics in the polytechnic. She was absolutely clueless about the job prospects for a mechatronics engineer. I asked her about her aspirations and she replied that she really wanted to work in the games industry.  In our dental profession, equipment have evolved from simple mechanical to electro-mechanical to logic-driven electro-mechanical and currently to computer driven machines.  The medical equipment suppliers who employ mechanical engineers and/or mechanical engineers cannot cope with the repairs of the newer equipment. And many times end up changing whole modules and whole machines just because they cannot repair them. But I think HR is afraid to employ a mechatronics engineer just because they don't know what a mechatronics engineer does. Mechatronics is much more fun. It combines almost all of the engineering sciences and produces an all-rounded engineer. But until HR changes their mindset, not all door will be open.
