    Many thanks for the multi tool tip, I've owned a multi tool for years and never thought of using it on the car resto. (classic mini 1275)

      @@teabelly1565 I do like using the multi tool for removing the bulk of the material. It's especially good where the seam sealer is thick, or on the edge of flanges. Because it cuts, rather than melts or smears. It will still need a finishing pass, and it may be a little slower process, but I like it for the reasons I've mentioned 👍

    Hi. Just found your channel, subscribed and binged all your videos! Apologies in advance for the length of this comment. You're doing a great job, and you've amassed a fine collection of tools to do it justice. I'm 72 now and probably on my last project, a 1998 E31 840Ci. It is fair to say it is killing me slowly week by week! I've been restoring for about 10 years and have done 3 cars now, including all the painting, one of them an E34 (I still have the car, it is about 3/4 finished) which has a fair bit in common with the E30. My first BMW was a 1987 E30 320i (shame you don't have the straight six), it was only 3 years old so I didn't do any bodywork at all on it during the 6 years I owned it. I'm no expert, but I've made a lot of mistakes to be learned from. You are obviously very capable, so I doubt I can teach you much, but here are a few things. I have also had issues with weld through primer, and am of the opinion that all of it interferes with the weld, which may be why it was never used during manufacture to my knowledge. There are so many products out there, but I have put my faith in these companies: Rustbuster, Bilt Hamber Laboratories, Dinitrol and Fertan. For me, they make the best products. Do NOT use POR15, it's total junk, everything I have painted with it has failed. Do not bother with etch primers, go straight for a good epoxy primer. Rustbuster do some excellent stuff, they make some 2 pack weld through primers which I have not tried, but if I had a lot more welding to do I would give them a try. Their Epoxy Mastic is fantastic for chassis and suspension parts. Fertan is the best rust converter IMO. It looks and smells different to all the others, is German designed, and comes out of the marine and oil rig background. For the bolts you mention, I presume you mean the annoying self-tapper type threaded studs welded to the body used for heat shield securing among other things. For the ones that can't just be cleaned and treated, I have referenced their position, cut them off, ground the metal flat. Then, get some M6 pan head screws the right length, for the ones that are under carpet, they don't need to be completely flush, so grind the pan head down to, say, 2mm thickness, drill a hole and weld from the other side. If you can't get to the other side, or you need a flush fit, grind them down more, drill a hole the same size as the round head you are left with and weld them in flush. For complex shapes, don't be afraid of welding a few pieces together rather than struggling for hours to make a panel out of 1 piece. Lastly, you probably already know, but YT channels to watch for inspiration are: Fitzees Fabrications, Yorkshire Car Restoration, Ben's Classic Bodywork, GT 1900 Garage, Dave's garage, Notevn, Trev's Blog, and Elin Yakov's Rusty Beauties. Looking forward to your next episode.

      Thank you every much for the reply, some very useful information. This is my second BMW, the first was a e34 touring, which did have a straight six! it had next to no rust in it so a better start point, but its the e30 that I really wanted, so its time came and it went.
      I have been using etch primer, just because it flash rusts very quickly. My intention is to repair an area, ie the whole arch, then epoxy the whole area, rather just epoxy little bits. However having just done this to the arch, it does add some extra steps
      Dont worry, I wasnt planning to use por15, im still undecided if I will paint the suspension bits or to have them powder coated, the powder coated parts on my fiesta still look fantastic after nearly 15 years.
      I was also thinking of doing that exact thing with fixing the studs, it seems the most straight forward repair.
      Thanks again for the comment, glad you have enjoyed the videos 👍

  • @rtwpsom2
    @rtwpsom2 Месяц назад +1

    For studs like that in such small numbers I prefer to find a matching but slightly longer bolt. Grind the head down until it looks like a rivet head. Shape it, but don't remove any of the diameter of the bolt head. Cut the original stud off and drill a hole to suit. Put the ground down bolt in through the back side and weld it in place. Try to get decent penetration all around because you are going to grind this down as well. It doesn't need to be flat, but just rounded over so it is relatively smooth. I realize decent penetration without burn through is tricky on such thin sheet. You can add a washer under the bolt head and weld it all if that helps, but in my relatively limited experience these bolts don't really need to hold up any ten ton anchors.

      So this topic seems to be debated alot! And yes, for thicker metals I do normally push the weld (You can see this in my DIY car rotisserie video if you are interested). However, at least for me at the moment, I have been getting a better result pulling while welding thin metal.

    I've started in on the bodywork of my classic mini and seem to be forever welding!
