Hi Stefan,
I visited Castle Combe yesterday and saw cyclekarting for the first time.
Am hooked after talking to the guys who were all very friendly and informative and have decided to do a build.
I guess getting a set of springs is a good start - so please put me down for a pair if not too late.

The original 5/6 I thought were needed may not be now.  But so far I think the following people have asked for a pair:

Steve P
Chris L
Chris B
Rich G
Graham H

Anyone else?   I'll follow up about the 5/6 and then contact Midland Motor Springs to place the order and hope they'll do the same price.

Just picking this thread up as a newbie. Springs seem to be the 'hard to find' item - I think I have sources for most other bits though will need to check periodically.
From what I've gleaned - I contact Midland Motor Springs, whisper 'invoice 42751' and they'll know what I'm talking about and expect £110 to £120 for a pair.
Have I got this right?

My I suggest an alternative supplier you could make contact with, this being Jones Springs. Rhys and myself bought 2 sets of springs which cost £115.00 per pair.
The sizes were as detailed below and if you need any further info about them the man to ask would be Rhys as he has a noise for finding suppliers.
Once again, I would suggest this parts issue has identified the possible need to create a club parts supplier list.
By this I mean that the membership can consult said list when looking for parts rather than openly posting requests for help. I think it would save a lot of time and help everyone.

Springs:-

Width.              35 mm

Thickness.          5 mm

Eye to eye.      590 mm. (Straight line)

Along length    660 mm

Arch.               100 mm

Comes with bronze bushings to take M10 bolts.


Regards

Scotty

Latest set of springs ordered from Midland Motor Springs were much more expensive.

Just to say I’m still up for a pair of new springs from somewhere or other…
Iwonder wether it might be worth an email to Gemini to try and get them interested in buying a load to go along with the rest of their CK parts?

[I did approach Gemini a couple of years ago but they were unable to secure sufficient discount to make it worthwhile.]

Jones springs are happy to make pairs at a time, no price break for multiple sets.01215687575
We must avoid torturing our brains with false problems, it occupies but it can annoy. In jest!

I'm wanting a pair so I'll give them a ring.
I've seen different cambers shown in different places - 100mm recently.
I guess I'll have to do a full size drawing to check.

Just to confirm, because the price with Midland Motor Springs went up so much and the discount for multiple sets was marginal, I'm not pursuing that any more.  Sounds like Jones might be the best bet at the moment and we all keep a look out for someone who might be able to source or make them cheaper.

Thanks, Stefan. I'll give the a call tomorrow and repost back.

I've just returned from Owen Springs, Rotherham.
Prices for springs from 1 1/2" x 3/16" (it's all imperial size steel), 570mm span, 80mm camber -
EACH -unbushed (3/4" eye) £68, bushed for 1/2" £88  - based on 2 springs (one pair).

And one for the committee to consider -
Based on 20 springs (10 pair) unbushed £51, bushed £61.60 each
plus vat and carriage if needed.

It appears that material costs have risen sharply over the past 12 months in addition to processing cost (gas for heat treatment?).

I shall get a current price from Jones Springs before placing an order.

good info, David. thanks

I am going to be looking at springs, but I am after quarter elliptics. Steve Vinson says they are generally 1.25"x24" - but yet to find out from him how thick they should be.

Does anyone else know the thickness of 1/4 elliptics?
I don't want to bore you all with the details, here. But if you are interested, have a look at my blog https://peteskart.blogspot.com/

My 1/4 elliptics are 1.5" x 3/16" thick, I have no idea if this is any good as I have not raced the cycle Kart yet.
