Model T Ford Forum: Forum 2012: Chev track width question....
Top of pagePrevious messageNext messageBottom of page Link to this message  By Shawn Hayward on Tuesday, June 05, 2012 - 05:37 pm:

OK
the sorry for me part first,,,,:-(
just recovering from triple hernia op,
so NO moving,,
Now the question does anyone know off the top of thier head track width for a chev 1929???
it had 19 " discs
as well do you have a picture of the hubs on the axle?
I will be machining some adapters as soon as I can walk around again, and am hoping to match the "T" track width
I am guessing 1/2 inch spacer may match
thanks

Sorry about your pain. Was it an injury, or just the luck of genetics?

This is probably everything, except what you ask for.

thanks Rick
the short answer...stupidity,,,
built a barn a few years back ,
put the beams and roof up myself
and "being indestructable" most of my life didn't help lol
laterall muscle tears is how the Doc described it


I am thinking if I can set the spacer thickness right, I can avoid the need to "adjust" the settings from the originals
I will try to draw amd scan my thoughts for the fit up tomorrow,
If the chev wheel disc has the bolt surface inline with the centerline of the tire,
I need about 1/2 the spoke wood thickness to make the tracking match original???
useint "T" hubs
open to all suggestions and knoledge

I don't see what the Chevrolet track width has to do with installing the wheels on a Model T. Model T wheels are zero offset. If you have to install spacers on the Chivverlay wheels they are not going to be zero offset.

Why not plug and redrill the hubs to match the Chevrolet pattern? It will be stronger easier and cheaper.

I am thinking,,,track is not important,
will vary with axle width,

OOPS!!!
wheel center line chev to wooden "T"??


Top of pagePrevious messageNext messageBottom of page Link to this message  By Shawn Hayward on Tuesday, June 05, 2012 - 06:50 pm:

Royce ,
I was thinking of this, but the chev wheel has about a 3" center and I can not check right now but maybe zero offset too
so strength at the hub (3" ring), and the distance from the "hub face" to where the center of the wheel
(1/2 spoke thickness)
is my question
will this be a concern??
I know some have done these
thanks

PS
I guess to discibe the spacer
it will fill the 3" center hole,
the T hub will fit throught it
and It will "move" the hub face 1/2 " out

make sense???


Top of pagePrevious messageNext messageBottom of page Link to this message  By Royce in Dallas TX on Tuesday, June 05, 2012 - 06:58 pm:

Maybe machine off the wheel mounting flange, make a mounting flange to fit and have it welded to the T hub.

I am not real keen on the spacer idea. It's going to have heavier steering with additional offset plus it will add stress to the wheel bearings, spindles and axles.


Top of pagePrevious messageNext messageBottom of page Link to this message  By Shawn Hayward on Tuesday, June 05, 2012 - 07:12 pm:

That is option "B"

I will have to draw what I am designing so we are all looking at the same Idea
I am hopeing to aviod the weight and stress redistribution problem with the spacer,
as the disc wheel is thinner and I would be moving the center line and weight "in" towards the inner flange and the center of the car without the spacer I think


Top of pagePrevious messageNext messageBottom of page Link to this message  By Shawn Hayward on Tuesday, June 05, 2012 - 07:51 pm:

hope to make this easier to see my idea


now if I remove the wooden spokes the surface that they sat against is what I am reffering to as the face , the bearing hub will be unchanged
If I directly bolt the chev disc in place,
I think I will be moving my wheel center "IN"
by 1/2 " on both sides on the car as 1/2 the spoke thickness will no longer center the wheel ??


I will no longer be useing the outer plate but the rest of the hub is unchanged
does this change anything?

Shawn,
The burgundy car in the middle is my 29 Chev and it has 20 inch disc wheels. I don't know what year has 19's


Top of pagePrevious messageNext messageBottom of page Link to this message  By Shawn Hayward on Tuesday, June 05, 2012 - 10:20 pm:

Mike
I have been offered some 20" wheels to , they seem to be the same "offset"
I have been debateing which ones I want??????
I think that the face of the wheel where it bolts to the hub is ceneterlined with the wheel
does this seem to be on yours?

nice coupe

I'll try to remember to look in the morning. I would imagine with all the 30-31 Model A's around that 19's would be easier to get tires for.

MY thoughts exactly.
thanks

OK I see what you mean Shawn. A spacer will work fine. You just need to shoot for zero offset so the T geometry is right and the bearing loads are unaffected.

Royce,
I have access to a water cutting table,
(friend of mine precision cutting)
so I think it may be a chance to make something
that "T" guys can fit on a ford hub,
I can change the "bolt pattern" to an "A" wheel
or a "T" wire , and if I damage a hub ,..
it's an easy fix

just need to be sure of the tracking on the finished product

have not started yet,,,,,idea's are welcome

thanks

Shawn, A 1/2 inch spacer puts the tire almost exactly where the spoke wheel would put the tire.
I am not a mechanist, but I did my own spacers and used the Ford outside plate from the spoke wheel which almost covers the Chevy lug holes on the wheels. The 1924 roadster pickup steers and handles good and the rear spacer just clears the wheel away from some accessory shocks.
The pickup is not show quality, but after everything was painted, it looks good and the Chevy wheel holes just barely show.

Willie
do you have any pictures?
and have you ever measured the track?

my goal is to make a quick change set up if ever I have a damaged hub, and to make it easy for all to use

I will post pictures in a week I hope
thanks

Shawn,
Looks like the center of the Chev wheel is real close to the centerline of the wheel. I didn't take one off and check it.


Top of pagePrevious messageNext messageBottom of page Link to this message  By Willie K Cordes on Friday, June 08, 2012 - 01:47 pm:

Shawn
I did a rough measurement on the front end and it seems to measure 56 inches from center of tire to center of tire at the bottom where it rest on the ground. That should be correct for a standard width Model T. A wide track would read 60 inches.
I will post some pictures, I hope this helps you.
Sorry about picture quality but the T was in a shed with a flat tire and I could not move it when the wheel pictures were taken.

Update on wheel adaptors

1)started with cutting out pattern


2)fit to hubs
3)milled to shape

I have a 1/2 inch spacer built into these, as well as support all around for the "T" hub
in the event that I damage a hub , it bolts out to be replaced
I have also set up for a "disc" to add braking if I so choose,
and in the end I have not modified a single original part, it can all go back together

Very nice work. Ever think about getting some made to sell?


Top of pagePrevious messageNext messageBottom of page Link to this message  By Shawn Hayward on Monday, September 10, 2012 - 11:39 pm:

Thanks Mark
I have to see if I can make them at a reasonable cost, I will post what they end up at ,
I know the more I order the less they will end up costing,
they may still be a less expensive alternative to other hubs, I can make them for wire wheels as well,
and they have the advantage of using the original hubs which are plentifull
so let me know if anyone is interested
