Nice...well done!!!

[bigford]

its starting to look like something! what are you building again??

[Cooper]

Brazed an end onto the final driveshaft. Had to make the end a bit bigger diameter so no slop would be in the diff ends. Some play, and the bronze is a bushing for shaft to rotate in. No weight on that just torque, figured a bushing would help guide it.


Internal and external snap rings will "lock" the bearings to hub and driveshaft housing. Now all the lateral forces will be eliminated from hub. That's what I'm working on next. Wanted to broach a hex pocket in hub,,, but way too much $ for rotary broaching. So most likely set screws or locking pin.

[9W Monighan]

What size hex are you trying to broach?

[ihbuilder]

Through hole or blind hole for your broaching ? You can make your hexes on the rotary on the mill if they are blind hole . If through hole, a hex broach similar to your key broaches aren't that expensive .

[Cooper]

Was thinking around 5/16. If I went the broaching way I would make the female part out of steel not alum. That would be the wheel hub cap. 1 , I don't have 2.5" steel stock, 2, not my favorite material to work with using small size drills/mills. (If I used the rotary table ).

I don't think a steel hex shaft would last too long in a aluminum socket, do you guys? Referring to the aluminum wearing quick, developing slop. What's your guys opinion on making the female hex socket in alum? My thoughts are on this small size 5/16 or 1/4" it wouldn't last. Or would a square hole be better? That is if I don't just go with set screws and a flat spot.

i think your best bet is the K.I.S.S method

This build is going to be so big n so heavy, KISS got thrown out the window long time ago.

ABSOLUTLY!! My "simple" ideas turn into a lot of spare parts for future builds!! I get lost in my own mind!!

[ihbuilder]

Is this for a drive hex similar to the trucks ? If so , .3125" is a lil small . The more surface area the better . Steel to alum. should be an issue if you go bigger other then the reaction you get when steel and alum are mated ( can recall the term )

[Cooper]

I decided to go with set screws, I have three equally spaced radially onto drive shaft. Using cone point set screws and will make small divits into shaft for added security. The shaft is just rotational force, retaining rings internal and external lock bearings to not allow wheel hub assembly to slide off.

She finally is showing signs of life, a temporary heartbeat from dewalt but some forward progress,,,,,,,,

Looking sweet RW. You got me all excited!

Ok now, minus the drill, what does that completed rear axle assembly weigh?

[TRUCKMAKER]

Wownice! Thanks for posting about Fusion 360 on the other thread, I'd thought about going after it and after reading your post last night I downloaded it and spent most of my free time today watching the tutorials.

Can't wait to see more of your truck come together

[Cooper]

I forget who told me last year about fusion 360 at cabin fever, thanks to them!! And Brian made a good point about learning with it, it's top of the line stuff so any updates in future I'll already have learned and will be easy to use.

Mario, you ready for this?????????

[Cooper]

For you north of the border (or if pic isn't clear) it's 13.64 kg

[TRUCKMAKER]

So for the guys south of the north border with piss poor eye sight and a slightly out focus number that's 30 lbs? What is the 1.2?

[Cooper]

30 pounds 1.2 ounces translates to BFT. BIG FUN TRUCK!! lol . She may be a bit on the plus side model.

[TRUCKMAKER]

Amazing, so all up may be around 75 to 100 pounds?

[Cooper]

It would be nice to keep it around 80#, easier to carry around. Or should I say lift
