vintage Kart find?
This is an old aluminum frame Kart I picked up....anybody have an idea of make?.....has a steel axle and a combo sprocket/brake set up...also a 1" aluminum axle.
That brake to me looks like a 6 inch Bendix with a bolt on aluminum drum cooler I think that Hagar 4 made them.
the sprocket bolts to the "cooler"
"Cooler" could be a self-oiling sprocket hub.
Thats a home built unit based on the McCulloch kart lines but built with aluminum they had a R-1 and a R-200 and 300 looks more like a R-1, I would say built in the early 60's the R-1 was real popular back then but quite pricey so it looks like they went to work and made their own. This is my 63 R-300 just after paint, the last of the Mac Kart.
Well whoever built my Kart frame certainly knew what they were doing.......This frame has no welds to contend with and is entirely assembled using aircraft style safety wired bolts and nuts...straight and strong design with quality aluminum components...It definitely has a manufactured front axle assembly as it looks to be a cast steel one piece unit, the front spindles are 3/4" and turned steel, not welded bolts......the rear axle is a turned aluminum piece that is super light....only drawback to an aluminum axle is dis-assembling them after they've been sitting for years....just takes time, patience, and a little heat applied dilligently.....Thank you for your input, you have a very nice Mac kart frame there and I would like to see your completed Kart.......Frank Davis.
