Bronze Build-up

admin

Had to do a little build up on a worn shift collar on a towing winch on an tug boat.  The manufacturer wanted $4000 for the new part I was able to complete it for about $700.Rough GrindFinal build-up before going to machine shop. Attached ImagesLast edited by 76GMC1500; 07-03-2014 at 12:40 AM.
Reply:Looks like fun.  Do they machine it.
Reply:Yes, two circles a quarter inch apart for an oblong hole.  An air ram actuates the assembly the oblong hole allows for the change in length around the pivot point.  I will try to get a picture assembled next week.  Tolerances for thickness were +.005 for diameter were +- 1/32.  Not that we care but it's a good place to start.  When I was done with it the part was all twisted and tweaked but it's really a crude machine to start with.  I figured if tolerances were critical the manufacturer would have used dowel pins of fitted bolts on the end but apparently tolerance was not an issue.  I bolted it together and told the machine shop not to touch that but use the pins on the top and bottom as the reference points.The funny part was that as I dropped it off at the shop I warned them about slag inclusions and that they should probably use HSS tooling and not carbide.  I have never done anything like this before.  They said they only use carbide tooling.  Luckily there were no inclusions and I was surprised to have almost no pin holes either in the final machined part.Last edited by 76GMC1500; 07-03-2014 at 02:25 AM.
