  • Restoring M29C-3284

    Hello all

    Like John is doing, I too am restarting my restoration thread that I had on the old forum. To recap, I bought my weasel back in 2010 after seeing an ad online. A quick deal was made and I went to pick it up.

    Well is wasn't all original, it had a Volvo B18 engine and M40 transmission installed. And was missing a few pieces of the hull. Luckily an original engine and transmission was included. Any who, being young and eager I started cutting away all the modifications done over the years. During the removal of all the unwanted mods I discovered some mods that looked to nice to have been made by "Garage Svensson" aka Bubba. More on that later...

    Having no space to do any real work on the hull, I started gathering the parts that I could not make for the hull and started to restore the mechanical parts for the engine.

    I known that the color on the radiator might be wrong, but I found black paint as the frist layer when I paint stripped the tanks to have the radiator re-cored. So I went with black.

      The engine is fully overhaul with new valves and valve guides. The valves seats where cut and lapped. The cylinders needed to be bored to +0,020 and the crank was ground 0,010 underside. So new bearings where installed for both crank and cam, and the connecting rod bearings where recast with new babbit. NOS clutch disc and clutch assembly where installed. And the flywheel was resurfaced and got a new ring gear. The transmission was actually in very good shape and the only parts that needed replacing was the thrust washers.

      I could not find any new oil and fuel hoses that matched the original, so I ordered the drawings from the Studebaker museum and made my own.

      So if anybody needs new hoses for their weasel, I can make them for you.

        While I was waiting on the engine to be bored and planed by the engine restorer. I started on some of the sheet metal parts that needed to be made.

            Three years ago I, my brothers and my father invested some money and built a new shop. And with that done I could really start making some progress on the hull repairs. I had removed the side skin and floor in our old shop and also welded in a repair piece of the part that was missing from the main bulkhead and the rear tunnel.

            I did some sandblasting to see how bad things where inside the hat channels, and all the rear hat channels needed to be replaced as well as the side angle, but that was expected. So new hat channels was fabricated. The vertical hat channels and the top parts where actually in very good condition.

            Some small patch repairs where needed in a few places.

              When I removed the old hat channels I noticed that it must have been hit by something in the back corner as the new side angle would not align at all. So I had to spend some time straightening and also rasing it a bit as it had sunk down a bit by not having a complete main bulkhead and the heavy hard top.

                After getting the main structure all welded in it was time for the floor skin. I had first planned on replacing the whole floor down on the center part of the hull, but seeing that it was in good condition I decided to just put the weld in the corner where the sponson meets the center. The weld will (hopefully) not be visible when the tracks are back on.

                I epoxy primed and applied Ardrox AV 100D corrosion inhibitor to the inside of all the parts that will be covered by the floor skin. We use AV 100D on the seaplanes we service at work and it works really good, so I hope my weasel will not rust as long as I will have it.
                One area that I could not corrosion protect was the flanges that got spot welded. I tried some of the weldable primers but none seemed to work any good. I had to set the setting so hot to get a weld that would hold, that I got brun troughs. So I left the weld areas unprimed.

                  Same procedure was repeated for the side skin.

                  The hull was then again flipped on it's side and the to skins welded together.

                          So we have finally ended up in the present The following was gone a few weeks ago.



                          With both sides back together it was time to get the back end back to original configuration. I had made and installed the exhaust tunnel side a few years ago without the hull sides in the correct position. So now when it was time to finish the back end, I noticed that the opening was not level with the hull sides, tilted up at the back. I decided to make completely new tunnel sides instead of tweaking and fixing the old ones. So with new sides made and installed I could make the other missing parts.



                          I actually bought two antenna mount reinforcements from a forum member on the old forum several years ago that I was going to use. But when now that if finally was time to use them, I had a good look at them and they where not in the best condition. So I use them as patterns and made new ones.
                          The back angle was also made and wire clamps welded to it.

                          Everything installed and ready for some primer and the outer skin.

                            Primed and and ready for welding. I also, like I did on the sides, applied corrosion inhibitor to the primed areas before welding.

                            Click image for larger version  Name:	IMG_6733.JPG Views:	0 Size:	111.9 KB ID:	380

                            Some 50 or so spot welds and some tig welding of the corners the outer skin was installed. I still need to weld the lower edge, I will do that ones I have flipped it over.

                            Then to holes where drilled and the exhaust muffler and guard test fitted.
                            There is one hole I have not drilled and it's for the marker light. I have two T24's that I took measurement of for the other holes, but on one the area where the marker light would sits is cut away and on the other there are several other holes in the same area and I can't tell which is for the marker light. So can anybody help me out? I need to know the hole diameter and the position from the L/H corner.

                              Alexander,

                              Between you and John, I am truly impressed! you guys are both "knocking it out of the park!" Amazing work on a tough weasel to start with... thanks for again putting your restoration on the board.

                              I'm sure the picture and details will be really helpful for many to see.

                              When I first saw your machine a few years back, I had my doubts that it could come back...you removed any of that! Wow first class.... really nice sheetmetal... you must work on aircraft for your day job

                              Great work and keep it up.

                              Best ,Rob
