which spindles from etrailer.com
should we use to build front axle?
will put chart in extra post
go to etrailer.com and type in 'spindles'
take you right to spindle chart
that's easier to read
we're leaning towards 1750 lb ones

Will the car go over 50 MPH???

The machining and alloys in trailer axles are designed for low speeds.

I wouldn't think of spinning one of them @ 100MPH:Stop:

This is what they are designed for (3500 pound spindles)



I used the 3500 pound set 'cause I had them.

:ditto: with CADplans

You might consider an early truck/van straight axle and use that as the platform for front steering and front suspension.

There are many aftermarket 'dropped straight axles' available too. They DO shoot a big hole in one's budget though...

 

[marlboro180]

I would thing something like this

would be more appropriate.

cadplans, mark777 and marlboro man
we're ok with speedway spindles for $149 a pair
and weld on axle end for $30 a pair
we're ok with fabricating axle from 2.50" tubing
axle will be STRAIGHT for strength
don't like early ford hubs at $130 each
WITHOUT bearings!
bearing sets are $70 each!
that's 4 bills for pair of hubs!

 

[matt167]

There is the old saying " you have to pay if you want to play ".... If you can't build it safe, than don't build it..... This thing would make a nice trailer queen with a foam block, But that's about it...

you don't need. hubs for the spindles. buy a brake kit or peice it togther for the Ford spindles. You could do with a set of rotors and bearings. Have the rotors turned down to the inner hubs, and then you'll have a set of hubs and bearings for cheap.. If you want brakes, then just add brakes and calipers

thank you matt167
do you know what disc rotors fit
these aftermarket '42-48 Speedway spindles?

matt167
found these at Speedway
1973-77 GM Midsize 11 Inch Brake Rotor
$40 each works for us
same as ones in their full brake conversion kit
anybody know if they fit as is?

 

[matt167]

just buy there forged spindles, and they will fit. You will need the bearings, but there available from speedway. A good napa could also match the dimensions for bearings

 

[MR RACING]

matt 167
so let's get this straight
1973-77 GM Midsize 11 Inch Brake Rotor,s
fit right onto these Speedway '42-48 Spindles?
we are going front brakeless but
will leave 'em alone while building
cut the rotor part off on a lathe later

 

[MR RACING]

thank you matt 167
ok
we're still going to use
Etrailer.com parts for another project
FYI the go fast specific saying is
'Speed cost money. How fast do you want to go?'
note the bungy cord holding spun aluminum
fuel tank on

 

[matt167]

Yep, indeed. it's bunjee corded on.. inspectors wouldn't let it anywhere near a track tho

 

[MR RACING]

thank you matt167
see 'Speedway Dragster Front Axle Kit' post
got things all sorted out
finally did notice you said GM speedway
rotors will fit

will build front axle straight like this
one for extra strength
probably hang it on leaf spring

we have jar of mini bungee cords
from walmart so we can handle
any situations that comes up
(click on pic to enlarge)

 

[matt167]

I do not see any bunjees on that. I see what appears to be a metal strap holding the fuel tank in..

A gas tank strap would cost $5 to make.. Bungee cords should not be used to hold on any critical components, or anything at all that would run in excess of 50 MPH... If your contraption will have a foam block and not run, than have at it. But making a show car that can't run the track, or be driven on the street. makes little sense at all

 

[MR RACING]

thank you matt 167
you're supposed to see straight front axle
not a dropped one
bends are stress risers
foam block?
you mean mockup block?
nooo!
we're using the bare block
from the Ford 292 & the Fordomatic to fabricate chassis
and then it'll be reassembled and bolted in

still curious about those GM rotors
do we use stock bearings or
do we have to do some bearing
swapping to get them to fit
'42-48 Ford spindles?

click the instructions PDF. it includes the parts list and bearing numbers you'll need
