Steering wheels,

[jlaird]

Oh joy joy, now if the hub was machined (maybe it is) so that the Sprite or Midget horn button would fit (not necessarly work) this could be a work of art. Seems there is a part for this that covers the bolts as well. Maybe I jumped the gun.

Don't forget to sign your work.

Okay, got the spline printed. it as a 36 tooth 11/16. (atch) pic and print. can any tell me what the difference is, or if there is one on earlier ones? what i dont have is a wheel and logo setup. does the center piece attach to the wheel or the hub?

Try this for how the boss works with the logo etc.

Mark,
I'll check tonight.

Matthew,
A lot of APC wheels use a 5 hole pattern like the Grant Signature series wheels. The Grant part # is 6560 for the install kit, it's about $60 new. (This is good from '71 to '77, '78/'79 is #6561, same price) I bought one on Ebay for around $10 and am happy with it other than loosing the horn. I need to fabricate a custom pencil arrangement this winter.

Chris

Ok, I'm almost certain that 5 hole pattern you refer to is the same one I've measured on this APC wheel. They're available on Ebay? I'll look it up right now! I remember looking at the Grant hub adapters, and not being sure if they would fit, or if they weren't just an adapter for the existing steering wheel hub (which can be unbolted from the "wheel" portion of the steering wheel).

One other question, does it make the steering wheel closer to you? That is a key concern for me.

Mark, I may be able to save you the trouble! If it's $60, with ones available as low as $10 ... probably not worth the time it'd take.

 

[Matthew E. Herd]

Looking at these grant wheels, it looks to me like they may be made by the same manufacturer ... the horn button on these signature series wheels looks just a little bit TOO familiar! /ubbthreads/images/graemlins/wink.gif

 

[ChrisS]

I don't know if there are any available now, I was just saying that they come up every once in a while used.

Chris

 

[Matthew E. Herd]

I checked the Grant website, and I checked two of their distributors (JEGS and Summit). It turns out that Summit has the 6561 in stock (JEGS has neither) at $42 each (plus a $9 handling fee, but free shipping ...). However, they don't have the 6560. I couldn't find it explicitly listed which years the 6561 was for on the Summit page or on the Grant page. I also wanted to know if this made the steering wheel closer to the driver (which I also asked). Hopefully they will respond to my email promptly.

On the other hand, for $42, I'm almost willing to just buy it. Chris, perhaps you could attach a photo of the installation and comments concerning the difference in fitment?

Thanks,
Matt

 

[ChrisS]

I’ll get some pictures tonight. The hub doesn’t make much difference in the position of the wheel; that is really determined by the dish of the wheel you buy.

Chris

 

[ChrisS]

Matthew,
This is a side view shot of the adapter and wheel. You can see it doesn't really move it any closer to you.

Mark,
My '70 and '73 shafts are the same as your sketch. The difference in the stock adapter is that the '70 doesn't have a pencil arrangement. Now I just need to get one of the bugeye wheels off...more to come.

pencil arrangement? guess i missed something. can you clarify that for me please?

the hub adapter shouldnt be a big deal to machine. however the details of how the horn button or centerpiece attaches to the wheel are kinda fuzzy on the moto lita site. i would guess that they attach to the wheel?

"pencil arangement"
I guess this is the sprung thing that connects between the slip ring and the horn button - it's a tube about the diameter of a pencil with a brass pin sticking out of each end and a spring in the middle.

 

[ChrisS]

Sorry about that Mark, I meant the horn push contact. The attached pic shows the hole where the horn push contact goes, left adapter, just below the center. The '68 to '70 cars had the horn as part of the directional switch. I'll post a pic of the back sides as well. How is the '79 horn set up?

Chris

 

[ChrisS]

This is the back side. There is a copper ring under the '73 adapter (upper) that acts as a rotating contact point for the horn. Right now I don't have a horn in the car, I'm probably going switch out the directional switch to the '70 style.

Essentially it looks like the adapter for a '79 would work for all years, but there wouldn't be a need for the directional cancellation tab for earlier cars. The hard part I would think will be the horn contact. I have no idea how the Moto-lita hub is set up. I found a shop in the UK that sells Moto-lita hubs a lot less than Moss, I sent an email inquiring about availability.

Chris

 

[jlaird]

As I remember there is a brass ring strip on the peice that covers the stearing shaft between the dash and the wheel.

There is a hole in the wheel/boss, boss in our case that a plastic tube with a spring in the middle and a small cable attached to two brass ends contacts the brass ring strip on the spacer between the dash and the wheel, there is a whole in the steering wheel that this tube fits. A small brass teat on the horn button and I think a larger spring between the button and the wheel hold on bolt. Thus connection is made from the large nut (ground) through the button down the tube to the brass ring on the dash wheel spacer.

Look in the parts manual for an ISB, it is really a simple arrangement for cars without turnsignals on the wheel.

it on the turn stalk.

So i take it they all have the same nut and spline set up. Now i need to know the bolt pattern, so i can determine the flange size on the adapter. Since i dont have a wheel at the moment. i also need to know what the center hole diameter is. i do recall that my center cap is just spring cliped in place, i tshould be easy to machine a catch for that in the adapter. wheel center section thickness needed also. Matt you wanna be the Guinea pig?

now i can either hob out the spline, or what i may try is to make a cutter out of the spline i do have.

modified adapter sketch (atch)

 

[Matthew E. Herd]

Heck yeah! I'll be the guinea pig. I have an APC steering wheel with horn button (we may need to think about the slight alteration required for the button on wheel configurations).

From contact with the Grant folks, it turns out that the tooling for the hub is broken, and the company that manufactures them is reluctant (but intends to) repair the casting mold. Because they apparently don't move a whole lot of units in Europe, they're being pressured by the US folks, so it will eventually be manufactured. If Chris could get us some dimensions on his hub, we'd be in good shape to go from there. Another option, we can get our hands on the later hub for $42 plus a 9.50 handling charge from Summit racing. Mark, might this help? It will fit grant's signature series, and (most likely) APC wheels as well. Different buttons are available for the Grant wheels (which I believe to be identical to the APC units), so if you don't like the emblems, that can be taken care of as well. The Grant wheels are rather expensive (about 180 on one wheel i happened to look at). I believe the APC wheels are somewhat cheaper, but probably won't have leather or wood finish (rubber instead). Depends on the look you're going for. Let me review the schematic and I'll get back to you on dimensions that you need. Anything I need to measure on the vehicle, I'll have for you tomorrow, as I'm going to attempt to finish reinstalling the head on the car.

Tony,
Any chance you can take some measurements of one of your Moto-Lita hubs / wheels? I attached a sketch of what I need, essentially it is the OD of the hub, the ID of the hub, the ID of the wheel (OD of the raised surface on the hub) and the distance between two bolts on the bolt circle. Any help would be greatly appreciated.
Thanks,
Chris
