Steelies Posted October 10, 2014 Share Posted October 10, 2014 soldier on man, only a few more months of being told your gokart isn't a race car then we can all be jealous you're out there breaking it and we're on the computer. 3 Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted October 10, 2014 Author Share Posted October 10, 2014 cant wait. im going to be ordering the rear axle soon, do you think a simple keyway will be enough to put the torque down? other options are to weld on a hub flange to bolt the wheel to, but this will make it hard/imposible to change the brake disk or sprockets in the middle, plus both of those items are going to need the same degree of fastning 1 Quote Link to comment Share on other sites More sharing options...
Ned Posted October 10, 2014 Share Posted October 10, 2014 on the chilly bin, the sprocket and the brake disc are key wayed on (with 5mm key) and can lock up wheels with the brake etc and no problems at all. Thats with 6.5 HP so not sure what you're looking at. Quote Link to comment Share on other sites More sharing options...
Vintage Grumble Posted October 10, 2014 Share Posted October 10, 2014 Yeh, a tight key way is ridiculously strong. Quote Link to comment Share on other sites More sharing options...

Ned Posted October 10, 2014 Share Posted October 10, 2014 Chilly bin has welded on wheels and i wish we never did that. SUCH a cunt for serviceability Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted October 10, 2014 Author Share Posted October 10, 2014 im looking at 30hp through mine. lol at og austin 7s being keyed, i guess having any weakpoint such as a keyway isnt too bad, might stop axles and chains snapping etc. whats the best way to get a keyway put into something thats just round? ie the ID of the rims im using, i will just get the engineering company to mill in the key when i get the axle made up.

flyingbrick Posted October 10, 2014 Share Posted October 10, 2014 Any engineering place will be able to mill or, broach or slot the keyways for ya, buddy. You WILL NOT shear the key if its all done to correct tolerances. If its too loose and your grubscrews come undone etc you will hammer the slots out and start rolling the keysteel over. There ARE other easier ways you can lock things together HOWEVER the labour saving will be made up by the greater cost of the locking device.

BlownCorona Posted October 10, 2014 Author Share Posted October 10, 2014 not too adverse to cost, this project has blown way out anyway haha what are the other locking devices? Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted October 10, 2014 Share Posted October 10, 2014 Taperlock bushes are great! There are many types and brands of locking/ clamping bushes and sleeves though. I'm having a blank on the actual names but if you phone a local bearing supplier and tell them what you are doing and what you wish to achieve they will be able to steer you in the right direction pretty quickly.

Mitch.W Posted October 10, 2014 Share Posted October 10, 2014 yourkeyway will be best, its simple and works goooood. in my kart proper race spec 125cc 6 speed 45hp i have only shared one axle in 2 years of driving it and it gets loaded up quite a lot more than those wheels will be able to hold Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted October 10, 2014 Author Share Posted October 10, 2014 That's good to know mitch. I think that's the path I'll take Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted October 10, 2014 Author Share Posted October 10, 2014 mitch is probably the right person to ask. but im looking at running a 1 inch solid rear axle. as i can get hubs to suit, and i can drill these hubs to suit drive for the wheels, brake disk and sprocket. surely 1 inch is gonne be plenty strong enough? ps thank to the mod that cleaned up the mess from last night, and thanks to the continued constructive input/criticism from most parties, its very helpful and welcome.

BlownCorona Posted October 21, 2014 Author Share Posted October 21, 2014 got my front suspension 99% finished, will brace up stuff in due course, esspecially the spindles, as i pretty much only tacked those in place before i ran out of time tonight, but my suspension at this stage feels excellent, its a bit soft, but i have no air in the tires and the shocks are all finger tight, so im pretty sure it will come up just right, also after seeing how the suspension works, im wondering if our 2 pages on trick steering design was in vain and a normal setup will work fine haha i will see soon anyway 4 Quote Link to comment Share on other sites More sharing options...
Beaver Posted October 21, 2014 Share Posted October 21, 2014 So you are running no springs? Im lost.... 1 Quote Link to comment Share on other sites More sharing options...
MKD Posted October 21, 2014 Share Posted October 21, 2014 You could always double shock the suspension if its too soft. Would the arms fit another shock eye in width wise? like those ridiculous yank trucks with 6 shocks per side per wheel etc. Drove past an old small bulldozer in a paddock with the sweetest front cowl and cover that would look mint on this..know you've got yours sussed though.

Mof Posted October 21, 2014 Share Posted October 21, 2014 Hey man great build My old man built us electric karts when we were kids (6v VW generator on 12v battery) He used a morris minor window regulator for the steering at the end of the steering column to the "tie rods" Kinda works like a rack and pinion and the steering wont be so touchy cut the long arm off (I'm sure I didn't need to explain that) 2 Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted October 21, 2014 Author Share Posted October 21, 2014 double shocks would fit quite nicely actually, will keep that in mind. beaver - they are like mini coil over struts, they are off the back end of QCR spec mopeds. the top cover is hiding the spring.
