    I just acquired a Baumann AG Buco 1320 Swiss Clock with all the parts except the rotator arm at the top. I have good wood working skills. Does anyone have these parts or part drawings? What is this clock work?

    Here is a thread that you might find interesting on these clocks Click Here. Can you post a picture of the one you have? It will make it a lot easier for us to help.

    I don't have one the same as yours, so I can't do a drawing for you. Hopefully someone else will be able to. In any case, have a look at post #7 on the thread I posted. That will show you what you are missing.

    Thanks Peter, for the thread and your willingness to help! The picture I found seems like a bar with two wooden weights on it. Do I calibrate the time by sliding the weights on the bar? How important is it that I get the weights and wood correctly sized, or should I just try scaling from the pic?

    Move the weights out on the arm to slow the clock and in to speed it up. The amount of weight you hang to drive the clock will also have an effect on regulation. As will the weight of the block weights (these often have a lead slug inside them) on the wag arm. All that said, they are pretty poor time keepers, so getting them within five minutes over a 12 hour run is about all you should expect. I would make the arm a little longer than you think it needs to be and then trim it down once I had the clock regulated.

    Thanks Pee-Tah, as I see you are often called! Some good reading on that thread, and they are an intriguing clock. I'll post how my repairs go.

    clock #3.jpg ok, so I have made the wag arm and weights, but when I put them on, just the wag arm is heavy enough for the clock. It seems like I need about twice as much weight for it to work correctly. I assumed this was a lubrication prob, and applied some graphite powder, but not enough. Do I need to disassemble, clean, or am I missing something?

    The wag arm looks great, but it is upside down. Not that it matters I guess. How much weight are you hanging? Both the main weight and the counter weight.

    The weights are the standard wrought iron ones that appear to have come with it. One weighs 1.141 Kg, the other 149g. I also used an aircompressor to blow off all visible dust/dirt. It does work with only the wag arm, at least for awhile, but then slowly comes to a stop. With the balances on the wag arm, it doesn't move unless I pull down on the main weight, approximately 2x weight and it moves as intended.

    Thanks for the weight information! Yes, those are the correct weights and the clock should run with them. I think you are going to need to disassemble it and give it a good clean and inspection. Something is steeling power. You shouldn't need to lubricate any of the pivots in this clock as they run in Delrin (a type of plastic) bushes. Our dear departed friend Scottie-TX who started the thread I pointed you to did a lot of work with these clocks. Have a look through this lot. If you can't find what you need here, it can't be found CLICK HERE

    Hi Peter,

    I finally got back to this over the Christmas break and got the clock working - turned out the block that holds the wag arm just needed to be moved up the shaft so it could rotate without friction. I'm slowly adjusting it to the right time. It isn't nearly as loud as I thought it might be. Thanks for your help! My next project is to make a wood case for an 8 day brass mechanism I found in an antique store.

    That's great news Entrepreneurx! It is always good to hear about another success stories. I must admit I find the action of these to be almost hypnotic. I had to stop the one I had running near my bench as I kept finding myself sitting and watching it, rather than working on what was on my bench. Good luck with the case project!

    I'm really glad I found this site. I purchased one of these without weights, decorative cap on the hour-hand post or the wag arm suspension thread. I was able to replace the thread with heavy duty sewing thread. To replace the cap, I put a dowel rod in a pencil sharpener and sharpened it to a point. I cut off most of the point so that I was left with just a tapered edge. I center drilled a hole and oiled the wood to match the clock. I fabricated weights from PVC pipe and zinc BBs. I left a hole in the drive weight so that I can add or remove weight to compensate for timing and humidity. The clock is accurate to within a few minutes per week.

    I just purchased one of these clocks (the Bucco 1320) at a yard sale and it is really neat! But I'm not a clock expert by any means and there is no instruction manual with it. I don't want to break it and I'm going to need to replace the weights (I may try something like DJN did and make the weights). Does anyone know where I can find an instruction manual for this clock? Any good advice is truly welcome!! Thanks!
