240dkw Posted October 1, 2017 Share #1 Posted October 1, 2017 Found a couple of balance tubes in the carb bin. Thought I would try my hand a welding alum. They turned out OK, but if you look close you can see the fill area as the wire I used must be a different alloy than the original alum. 1 Link to comment Share on other sites More sharing options...

madkaw Posted October 3, 2017 Share #7 Posted October 3, 2017 I'd be happy with that! Most folks won't notice the dissimilarity . I need to start practicing with my TIG . I want to weld in intakes myself !! Link to comment Share on other sites More sharing options...

(Meaning NO crankcase Ventilation) Not sure what you are saying . the PCV connection is still there under the left linkage arm where it always was. These have both the PCV and brake vac connections.

grannyknot Posted October 4, 2017 Share #10 Posted October 4, 2017 Now I see, I couldn't remember where the PVC opening was, here is a couple of balance tubes I did a few years ago, after all the grinding and sanding I couldn't bear the thought of polishing them too, kudos to you for going all the way. 21 hours ago, 240dkw said: Not sure what you are saying . the PCV connection is still there under the left linkage arm where it always was.

Sanding? 80, 180, 400, 800, polish? I start with a large body file, than finer files until the shape is correct. Than on to sandpaper going from 80 down to 600. After than a couple of 3M super fine and micro fine sanding pads. Than on to the buffing wheel starting with the black and finishing with the red polishing compound. A clean with Mothers Alum polish to finish it off. It is quite a bit of work to get one done. The most aggravation comes from the files loading up with alum and causing deeper scratches than the file. Link to comment Share on other sites More sharing options...
David F Posted October 5, 2017 Share #12 Posted October 5, 2017 (edited) I heard that running the file over a bar of soap now and then keeps the file from clogging with aluminum. Well, actually I heard this technique for grinding disks, but the theory should be the same. Tube looks awesome...me, too lazy to attempt such a thing. But, I am smack dab in the middle of polishing a vintage Airstream trailer. The effort is messy, and tiring for sure...after a few hours, I turn black.
