Fordson Rest-o-ride seat

[Jstaley]

Hi
I'm after a rest o ride seat or the dimensions of one to fabricate my own.

Cheers

If you don't have the rubber parts don't make one. There very expensive. Try to buy one with good rubbers. The rest is easy to make new.

[Jstaley]

Actually, the rubbers are quite cheep. Found a supplier in the US selling them for £25 each.

[henk]

I have seen prices up to 100 USD, but maybe they are cheaper now.
I have a vew documents that I will place here, but it has no sizes. I have a seat but it's stored away. Try to take some messurements in a while.

[henk]

The price was for a set of two.

Here are some exploded views.





Hope this will help.
If you need measurements of certain parts, let me know and I will see if I can get them. Taking all the measurements of the hole seat is a bit much.

Hi
Thanks for the pics, I am hopfully getting the seat in the pics, it's not exactly the same as the fordson and so I want to modify it to be the same as the original fordson one.
In order to change it I need to take out the folded sheet steel and replace it with the steel bar version:




So if you could help me with the measurements of the seat bar bracket that fits onto the cross bars i would greatly appreciate it.

Cheers

[Jstaley]

Can anyone help with these measurements?

[henk]

I will try to get it done this week.

[henk]

Hope this is what you are looking for?
I have notice that there are differences between the seats. Depending on the age I think. Mine is a 1000 series model.

Hi
Sorry but that's not the bit I need. I have bought a jubliee suspension seat which is simlar to the fordson one but the seat bracket and pan is different.
This is what I have:


What is different is where the seat pan mounts down the center. So I'm going to cut out that bit and use some steel bar to recreate the orignal bracket like this:


So I need all of the measurements required to remake the piece.

Cheers

[henk]

Because there was a red square around the bracket< i thought this was what you needed.
As I understand now, you need the part between the suspension part and the seat pan.
I try to do it Saturday.

[henk]

I guess you mean this part.



If so I will check the measurements this week and send the drawings.

[Jstaley]

Thats the parts! The seat has arrived at my local depo, just got to pay the charges on it from the us then I can start cutting.

Cheers

[henk]

The steel you need is 70 x 6.5 mm for moost of the bracket. The seat bracket behind the seat is 27x 4.5 mm.

[henk]

Here they come.







You need a rubber part on the end of the bracket.

[Jstaley]

Hi
Brilliant. Thanks.

Could you also give me the total length of the back piece:

[Jstaley]

Hi
Im now in a bit of a pickle, I've disassembled the Ror seat and the brass bushes are shot. Over in the UK prices for Ror seats is rediculas so looking in the states but would cost $45 to ship back. Now as the prices are just stupid I'm planning on machining my own. Are they basic sizes or would I need to lap them to fit tight?

Cheers

[henk]

I don't think it's a narrow fit, so machine them to fit directly on the bars.

[henk]

Does anyone know if one can vulcanize the back plate of the rubber back on again? Or would it mean to make new rubber parts on the old plates.

[Jstaley]

I think you have to get new rubbers all together. There is a company in the states that lays new rubber on your old steel frames.

[henk]

I'm restoring a ROR seat at the moment.
I thought it was finished. Was I wrong.
The problem with the rubber parts on the steel end plate is salved with some 5star power glue. I have drilled eight holes in it for a short screw and glue them in also. This is to lower the friction force between the rubber and steel plate.

I reassembled the seat, but when I sat in it and did a bit of jumping it went straight down to the bottom. Then I notice that the side brackets between the bottom plate and the bars were bended out.
I bended them back and tried again but the same result. It's normal steel. So they were made by one of the previous owners.

Now I'm after a new set of springs. Planning to make them myself, but I need some help.
First I need to know the thickness of the steel. 2 mm looks to thick.
Then I have to know the position of the bars. Are they standing a bit up or flat. My thought is that the springs must do their job to the inside and not outside, so flat would be right. But I’ve seen pictures with slightly raised bars.

I notice there are two different springs. A single and a double. What would be the right one?

I have some pictures and drawings to lighten up my questions.

This is the double spring.


This is the single spring and my seat is the same type. It has a small plate to fasten it.


This is what I think what it should be. Anyone knows how thick the spring is?


This is the second spring. I think it will make the suspensions much harder.


On the internet I have found the procedure for making a spring.
Bend the steel. Make it cherry hot with a torch. Cool it down rapidly in water or oil.
Make it hot to 220 Celsius and let it slowly cool down. Do it twice.

Is this the right way? Or should I do something more.

[arjan_brouwer]

Henk is a Engineer? Great drawing this way. Autocad? :p

[henk]

Thanks Arjan.
I'm just a simple assistant teacher, but I like to draw. It's a 3d program called Solid Edge. There are a few more of these CAD programs. AutoCad for instance has Inventor.

Anny info on the ROR seat?

[henk]

I managed to make the springs. There a bit different as the one on the drawings because I found out there should be some bushes between the spring and the bar. I wanted to make them 23 mm inside, but because of the strenght of the steel I ended up with 25 mm.
I have put them on the seat and they seem to work well.



I have use bolts and nuts to test it.

This is the second spring. I think it will make the suspensions much harder.

Can I find these springs somewhere as a reproduction?
