--- Quote from: bogstandard on January 20, 2011, 04:42:13 AM ---..... maybe you could rebuild that broken foot with some epoxy based putty, shaped and filed to match the original. By the time the paint is on there, you would never know it had been broken. It would only need a few thin pins putting into the casting for it to grip onto, just to give it a bit of support and strength. John --- End quote --- Or even stand the base on a flat surface, put a light film of oil (release agent) on one of the good feet, build a little coffer dam round it with Plasticine or something, fill with plaster of Paris, and thus make a mould. Put some thin pins into the poorly foot, pop the mould on and fill that with poxy resin. That might reproduce the "as cast" surface finish. Andy |

John, Nick, Andy. Thanks for your comments! :thumbup: Frankly the foot is some distance down the list, as yet..... I'm surprised you're recommending poxery resin. Will it stand the heat? :scratch: I was contemplating Jack's suggestion of a piece of cast iron and silver solder...... Though, I'm not confident at high temp soldering, as yet. ::) My main concern, is to get this project finished to running condition, ASAP. As a pal wants my mill and r/t etc. He is offering very sensible cash for the assembly...... Allowing me to upgrade a little. :ddb: One more step along the way, this afternoon....... Opened out to 7mm...... Rather out of focus, 5/16" slot drill, 3/8" deep....... Leaving a small step in the bottom, to support the depth of the 7/8" long tubes...... Looks ok, I think....... That's it until next week. Busy weekend, including a 1st birthday party! David D |
| NickG:
Looks great David, not ok! :beer: |
| Dean W:
Yes, looking very good David! With all the work you've done, this has been near the same as building the engine from the raw castings. Dean |

Hello David, you've been moving along quite nicely since the inspector got out of the shop, and back at home, did you ask the surgeon if he was going to post a build log on the madmodder site? Perhaps an invitation would have brought out the artist in him :lol: glad to hear your little darling is going to be fine, bit of a start when you spoke of being in surgery and all, glad to know it was something easily fixed and not a major deal. I think you've done a very nice job in thinking through your alterations, and you are going to end up with an engine that can be hooked up to something to do work, from the looks of it. I would readily follow Bog's idea if I wasn't so sure a piece of scrap iron and the silver would do the job. As he says, if it's going to get paint, you can always make it look right, but I'd still do the silver and iron or steel or for that matter, you could simply puddle up some brazing with a clay dam, with the whole sitting on a brick, and then file it to shape, and it wouldn't show with paint on it, and high temp paint will definitely stay on for quite some time, it stays on the heads of an iron head Harley sportster for about a year before it finally goes away, and they run hot, right on top. I don't know if it's available or common there, but I get wrinkle finish high temp paint here, it's rated at seven or eight hundred degrees, and the wrinkle finish makes cast look great, and hides any cracks brazed up or the like. I use it on all the Harley cylinders I bore and hone and fit for pistons because nothing else looks as good on engine cylinders of iron, and air cooled. It dissipates heat well too. I think you've got a real piece of work there and very nicely cleaning up to run. I'm really looking forward to seeing it finished, and watching the video. :bugeye: :beer: cheers mad jack |
