Hello everyone,

So if you read my introduction you will know that I am keenly interested in making my own bespoke watchmakers tools. Ultimately I thought what better set of tools to make for my first building of watchmakers tools than a set of screwdrivers! I'd like to base them off the Bergeon 30080 set, but put my own high end flair on them, such as hardened and tempered flame blued screws for the blade and the rotating head, a nice polish and lapping, and perhaps some rope knurling, as well as a custom rotating stand complete with vials for extra blades. Now all I need is dimensions, preferably from the most recent design of the Bergeon 30080 screwdrivers (it's my understanding that the current ones are a bit more substantial than the earlier ones, I think they did the redesign in 2016). Below I have made a diagram of the dimensions I am in need of. Some of my design will be a direct copy of the Bergeon, others I just need the dimensions to get some basic numbers to work around. I'm well aware that there are a lot of dimensions that I need, and that it might be somewhat tedious to measure each and every screwdriver in the chart I listed, but if anyone is willing to give me a hand, I'd much appreciate it. I thought it would be a good idea to start with what Bergeon considers the standard set, and make the non-standard sizes as I need them. I plan on making two sets, one for angled screwdriver blades, and one for hollow ground blades.

I would suggest picking up bags of replacement blades from Burgeon, and making a handle from scratch to your needs. You may want to alter diameter, length and other details to make them "yours", but I've learned that for the cost of ten-packs of replacement, polished and anti-magnetic blades, it's not worth me trying to re-hone and polish them, with finally demagnetizing them. They work out to a buck n change per blade. I can't make them for double that price, and they won't be as nice.

I got some in recently, and I hadn't realized how magnetic the original (also Burgeon brand) blades were. Plus the replacements are very finely polished- really a joy to work with. Finer finishing for sure than the originally supplied blades.

I do appreciate your desire to make everything, and I'm not discouraging you, but the blades are sort of like re-sharpening the blades for a carpet knife. Of course you can do it, and probably to a higher standard, but you will waste a month of your life making screwdriver blades you could spend making a rose engine for example. And you won't save a dime.

I also make tools, where it makes sense to do so. But as I'm a bit older, and third generation "mechanic", I've learned sometimes it makes a lot more sense to buy certain things and make others. I am also not above altering tools as needed for a specific job. Plenty of expensive wrenches that have been heated red hot and bent to a specific angle for a specific job in the box.

So, make the handles- get a piece of brass round stock (or 316 stainless) and have at it. But the bag of blades (I go through 1.2mm the most) and make up a handle. I'd even say: jewel the pivot at the end. Why not?

And I got a set from Otto Frei several years ago, to replace the A-F set I started with. They have the colored plastic ends, rather than all metal like the ones you posted. I personally like the larger flared plastic ends, and larger color code area of them. Probably the easiest way to get all the dimensions you want, is to buy a single driver along with rodico, watch paper, oils etc. you will purchase anyway as consumables. Then you can use, feel, evaluate and change the driver to be perfect for you.

More than two cents, but my thoughts on this...

Thanks for the thoughts! I actually found something that can help me, Esslinger publishes basic dimensions on their website, in imperial, but still, it's easy to convert to metric. The drivers .5 mm to 1.2 mm drivers are 2.75 inches long with a dia. of .1875 inches, the rest are 3 inches long and .25 inches in diameter. With basic dimensions I can work things out!

Actually I checked, the smallest 3 sizes are 2.75 inches in length with no diameter stated, the next 2 are longer and the length is not stated, but .1875 inches in diameter, and the next 3 are .25 inches in diameter, with no length stated, and the biggest 2 are 3 inches long, but the diameter is not stated.

      Kalle Slaap said he is visiting London this week in order to see the exhibition. I was keeping an eye open, hoping to meet him.

      Notifications

      By JohnR725 · Posted

      if you're trying to keep track of conversations scattered all over the message board emails are an absolute must.   looking at the bell icon on the top of the page versus the emails today it looks like I got the correct amount of emails. So making some minor change based on the one of the images up above I started getting notifications again. But at times I still have a suspicion that something isn't quite right. I have some feeling that the message board may delay sending emails until something so seems to be a long delay between when you get your emails just a weird feeling things aren't quite right oh  and then even though I do seem to be getting emails I no longer get notifications of personal messages I don't find that out until I arrived at the message board where I'm pretty sure I used to get notifications of those two. So something is definitely changed on the message board. then for everyone not getting emails you do want to check your spam folder. I have found that sometimes were open up an email the system I use warns me that it thinks the email is evil and bad and I have no idea why he thinks some of the emails are and some are not. But this is actually the program I use not the email system which also has a mind of its own as to what it considers spam so you should always check your spam folder.
