Holy Cow. that plate must weigh mot than the engine

It's only 9 Lbs

 

[chancer]

That is heavy. My 79cc predator only weighs 22. Hey maybe you can do wheelies.

 

[HippieHeadShot]

SUCCESS!




I was able to weld a 3rd cross beam and mount the a arms correctly giving me a 90 degree angle so the tires will run level with the ground!

I'm so relieved this worked out!

In the pic I show the finished right a arm, then the right without the a arm attached, and finally the left which shows the two cross beams I was originally going to use for mounting the a arm brackets.

Yes I know some of my welds are fat and dirty, but remember this is my first welding project!
I have a small test frame 2ft x 2ft that I beat the CRAP out of to make sure my welds were strong.

I think you are doing a good job!! Well done

Congrats!
Where did you get those pivots for the A-arms to attach to the spindle?!

The A-arms I got with the ball joints welded / riveted in place. I made a small bracket that I'm going to weld the spindle to, then use lock nuts to attach it to the A-arm ball joints.

I believe the pivots are tapered. They're made for a thick spindle, which is required since no kingpin is used. I know this because I have the spindle I'll upload a pic to show you, this weekend.

The matching spindle is also tapered, 14mm top, 12mm bottom of each hole. I think these joints take a heavy load. Just curious how your design turns out.

Indeed they do; it would be in your best interest to grind down & reinforce those welds; some look ok but, others look downright dangerous; remember, your life is at stake!

yeah I would have just used the spindles that come with it but they were 80 bucks a pop which is insane. luckily the bolt nut itself doesn't taper, just the non-threaded part.

Flux core welds. One thing I always do is immediately take a wire wheel in my drill and get that white junk off the welds. So you can see better and especially before listening to us critics here. Give us and yourself a good look at the weld not the flux dust. Also if you need to touch up a bad weld you don't want to weld over that crap.

I always take my wire brush to it if I have to take a second pass.

picked up a seat and seat belt today got a good deal on it. fitted installed the seat belt. she has a sliding mount so should be perfect for making those adjustments for shorter or taller friends. this is just a quick mockup and yes the frame is upside down.

fitted installed the seat belt.

Hold up, will this have a rollcage? I don't see any mention of one...

Yes! I will for sure have a roll cage installed. Even though I will be on flat land and pavement 99% I still want to put some vertical support in.

Here's the spindle pictures I promised. I got them second-hand of a quad, roughly 50 US $ for spindles, hubs and drum brakes with all the nuts and washers included.

Yes, the thread part of the joint is not tapered, only the smooth part is.

Wow those are completely different from the ones that come with these a arms, I wish I could have gotten those.

As a side note my re-order correct size spindles came today, once I'm off work I'll get the welded up and have a rolling kart!

New correct length spindles arrived late last night finally got the wheel situation figured out. I had to abandon the double sided bracket idea due to the multiple pivot points. it would have been able to turn both on the a-arms and on the spindle so I got tabs welded and will be using the a arms as my pivot point.

About to start welding the shock supports and mounting the shocks.

Hopefully I will also have time to add strut supports for under the seats and get the floor panel welded in place so the seat can be mounted.

I still have a ways to go but the end is in sight excluding the bodywork fenders, side panels, etc. all I have left is to hook up the steering, throttle and brake pedals, plus the roll cage.

UPDATE:Got the floor panel finished as well as the shock mount and cross brace. unfortunately I ran out of flux wire before I could finish.

I'll have to pick up more in the morning and finish welding the floor pan and actually bolt the seat in.

UPDATE 2:. finish loading up the floor pan and got the seat mounted properly looks like all I have left to do is hook up the steering, gas, and break then I will be good to test drive!

Its looking good. As far as the welding goes you could always do like I do: weld, clean, grind near flat, reweld and repeat again lol. Last weld I just leave, no need to grind again, and I can guarantee thise parts will never come apart.

Lookin good Hippie!

Those spindles start to look more heavy duty now. Did you weld mild steel to the spindle's hard steel without any problem?
