    Sooooo....tonight I got a bit done. Companionway and some other small parts painted, the companionways installed, holes drilled for red railings and a test fit. Very close to getting above decks done, need to paint the seating and install that, finish the deck and hatch, and paint and final install on rails..then itโ€™s ballast and electrics.

    ๐Ÿ“ Motor Questions and thanks
    6 days ago by Cashrc ( Petty Officer 1st Class)
    Flag
    Hi yโ€™all..first thing, thanks for the kind words and comments on the Taucher, itโ€™s very much appreciated. Secondly, how shall I power it? The kit came with a decent 550 motor with a built in fan, and the torque ring around the can reminiscent of the old Speed 600 motors. Iโ€™m thinking that on direct drive Iโ€™ll be pushing this motor on 7.2 volts. If you look closely in the pics, I have a 3-1 gearbox intended for off road crawlers bolted to that motor. My other option is a Marx Monoperm super, or a slightly hotter 27 turn open end bell motor and the gearbox. Anyway, those are my thoughts n this boat, opinions, ideas and/or smart-aleck comments welcome!๐Ÿ˜

    Hi Cash,
    "Iโ€™m thinking that on direct drive Iโ€™ll be pushing this motor on 7.2 volts."
    There are "zillions" of 550 motors!
    Are there any serial / type numbers printed on the can?
    Have a look for yours here-
    https://www.google.com/search?q=dc+motor+rs-550&client=firef...
    I don't think any of them will have the slightest problem with 7.2V and a prop (3 blade I presume?) up to 40mm or so. That type of ship isn't exactly a sprinter anyway ๐Ÿ˜‰
    Cheers, Doug ๐Ÿ˜Ž

    Looked at the motor and thereโ€™s no markings I can ascertain with the naked eye..zip, zilch, nada.
    Not looking for speed per se, just so good low end grunt. I have the same setup in my Springer, top throttle for that hull is a little much, but kind of what Iโ€™m looking for in the Taucher, while mid range and low end is great. I think Iโ€™m just worrying myself due to the weight of the Taucher, as sheโ€™s the biggest and heaviest boat Iโ€™ve built so far. What I think Iโ€™m going to do is put a power system in and Iโ€™ll do a static test in the tub with the wattmeter. Iโ€™ve included pics of the kit motor with gearbox attached and my Springer setup.

    ๐Ÿ“ Detailing the pilot house and 2nd lash up
    7 days ago by Cashrc ( Petty Officer 1st Class)
    Flag
    View All
    So, the few guys we had ready to sail today decided to postpone due to people being out for various reasons, and itโ€™s just too doggone hot in Texas in during most of August. I can deal with highs in the 90s, but when itโ€™s 100 or over, Iโ€™m out. When I used to fly a lot, I would disappear from around the end of July to the first week of September. Iโ€™d rather sit in my somewhat air conditioned garage and build to utilize my hobby time than stand in a field, or at the edge of a pond holding a transmitter and roasting in my own juices.
    Anyway, I had taken all of the details off of the pilot house, and this week I masked the windows and did a repaint, as well as making another railing as the first one wasnt up to snuff. Today I added the details back plus many I had not finished, built up the catwalk, then spilled the holes in the pilot house that the catwalk support tubes will be glued into. I then did another lash up to see where I stand, and what adjustments need to be made. Iโ€™m that close to finishing all the details that will glue to the deck/hatch, hopefully next update will find that part finished.

    When Iโ€™m running her Iโ€™ll use clear hatch tape like I use on my sailboats. Itโ€™s โ€œcheatingโ€, but I donโ€™t like leaks. However, I do like leek soup๐Ÿคฃ

    ๐Ÿ“ The catwalk frame

    Did a little soldering last night on the catwalk support frame. I then did a lash up to see how it will fit on the deck. One I get this all fitted, I can start re-detailing the pilot house and start finishing all the details on the deck and hatch.

    Hi Cash,
    It is surprising how long it takes even to do that soldering job and to get it nice and neat.

    So, I mentioned in the first part of this blog some of my frustrations with the Taucher. One I failed to mention is the deck details over the hatch. On the deck you have the pilot house, hatch, then what looks to be a boiler and exhaust and a work table. Between the pilot house and the boiler is a catwalk, that extends from the pilot house and terminates in a ladder right up next to the boiler and table, and is directly over the hatch. This means this would have to be removed to access the hatch or one would not be able to get the hatch open without possibly breaking the catwalk. Dumb. Just not well thought out..so, I decided to make a larger hatch, extending from under the aft of the pilot house all the way to just aft of the deck machinery. The pilot house, machinery, catwalk, any details in that general area will be glued to the hatch and removed as a unit for servicing..the pilot house fwd rests on the upper deck, there will be false bulkheads glued to the deck to help keep the pilot house lined up when the hatch is installed. Anyway, sounded like a grand plan, but I didnโ€™t have a saw that would really cut the hatch out, as the deck is by now bonded to the hull, and I just couldnโ€™t get a good angle on it with the Dremel. Soooo..I drilled just inside the lines I had drawn and then just connected the dots. Then I was reminded of a little saw that a few of my friends use, a small hand held oscillating saw. I purchased one with the half moon blade and a sanding kit. This thing is great! It made short work of my โ€œbutcheryโ€ and I was able to clean up the hatch opening nicely. Iโ€™m waiting on the first coat of the repaint to dry co I can sand and apply a final coat, then Iโ€™ll start work on the rest of the hatch/deck details and paint and install the rails Iโ€™ve soldered up.

    You are doing a great job,keep up the good work.

    Unfortunately when they design these models they tend to forget about being able to get at all of the radio equipment as well as motors and rudder.

    Thank you Martin. Itโ€™s not my best work, but I think sheโ€™ll look good in the water.
    Just donโ€™t understand what the designers were thinking.

    ๐Ÿ“ Graupner Taucher Wulf-an ongoing drama
    15 days ago by Cashrc ( Petty Officer 1st Class)

    View All
    Hi yโ€™all. Just over a year ago a I sold off some of my hobby stash and decided to use the funds for more hobby stuff๐Ÿ˜ The Taucher Wulf kit from Graupner caught my eye, and I thought it would be a fun build..boy was I wrong!
    To be fair, at the time I bought the Wulf my only scale type boat was a Krick Felix and a Robbe San Remo that I had built in the early 90s, and again a few years ago. I knew nothing of ballast as the boats I had built besides the aforementioned were race type boats, and if you said โ€œgeared motorโ€ to me then Iโ€™m thinking of a Robbe or Graupner surface drive for fast electrics..but I felt confident in my abilities to build the Taucher. I knew that Graupner had been bought out and production move to Asia, and that the manuals werenโ€™t quite up to snuff as I had just completed a Micro Magic from their latest production run, so I figured I could handle the build.
    Now as far as the kit goes, itโ€™s pretty nice. The hull and fwd deck are one piece and molded from fiberglass and primered. The fittings and parts looked decent, and there was a lot of brass and plastic rod plus laser and die cut parts.
    The real problem with the Taucher is the manual and plans. There are a lot of exploded views, but very little, if any verbiage, no mention of ballast at all, no measurements, nothing. No recommendations for batteries or any idea or mounts for the batteries. The hatch is a little bigger than a large cell phone, which gives very little room to access drive batteries, and itโ€™s location leaves you no room between just aft of the motor and the rudder. In short, itโ€™s frustrating, especially since itโ€™s touted as an โ€œeasy build upโ€ kit. So, halfway thru the build I shelved it before it became a Viking funeral boat. I built 2 more boats in the past year, the Neptun and a Springer tug, and I learned a lot from both of them, so I pulled the Taucher from itโ€™s hiding spot and began anew. I will post some pics from last year, then Iโ€™ll post the most recent. I made some changes that would have been much,much easier earlier in the build, so they had to be done..so some of the pics are rather graphic and not for the squeamish๐Ÿคฃ
    Anyway, here we go, anybody with any good info on these kits feel free to chime in.
