I have been advised that they are willing and able to manufacture springs to any specifications required however they are moving premises and will be up and running by the middle of April.
They will however be retaining the same contact number and/or can be contacted via there website.

I have also spoken to Rossendale Road Springs who can make them to imperial measurements and require a sketch/drawing so what size hole is in the eyelet?

I ordered:
www.midlandmotorsprings.com £100+vat for a pair of springs with bushes (560mm centres, 5mm thick, 38mm wide, 80mm camber)
No job number at Midland Motor Springs but invoice number was 42751 (3/12/2018). Pretty certain the contact was called Roger.

Other than the details as supplied StefanN ( see posting of 1st April 2021 ) I would speculate that no drawings of the leaf springs in question are available however Midland Motor Springs should be able to provide said information via their Invoice No 42751. and with this information come up with a price plus supply date line.
I only bring this up as I would not like to see any build being stalled due to a supply chain/parts issue.
Should anyone have a drawing perhaps they could pass this on to Chris H as it would help with his attempt to secure these leaf springs which appear to be a build chock point issue, unless other members can provide details of other known suppliers?

Is anyone interested in leaf springs:
single leaf semi-elliptical springs
560mm centres
5mm (3/16") thick
38mm (1.5”) wide
80mm camber
12mm (not 0.5”) bushes in the eyes
I've got a quote of £108 per pair incl VAT if we order 10 pairs. 5 - possibly 6 pairs are accounted for, so are there 4/5 more people who want to join in? Shipping isn't included so I can arrange to have them at cyclekart events but other than that, shipping costs would be extra. We can of course order more than 10 pairs if wanted.

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.

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.
Post by: David F-R on 05 Feb 22, 12:10 pm
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?
Post by: Scotty on 05 Feb 22, 04:14 pm
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.

Jones springs are happy to make pairs at a time, no price break for multiple sets.01215687575I'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.
Post by: StefanN on 06 Feb 22, 08:26 pm
Post by: David F-R on 06 Feb 22, 11:46 pm
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.
Post by: David F-R on 09 Mar 22, 12:45 pm
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.
Post by: Tinworm on 09 Mar 22, 12:59 pm
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?
Post by: Mark Underdown on 09 Mar 22, 06:58 pm
Post by: Tinworm on 09 Mar 22, 07:27 pm
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.
Thanks. Have you tried jumping up and down in your kart?

Quote for 1.5" x 3/16", 570mm span, 80mm camber, 20mm eyes unbushed - £65 plus carriage and vat.
I shall be ordering from Owen springs. I can collect (12 mins by car) so they'll work out cheaper.

I'd be up for a pair of spring with bushes. However, not in any immediate rush as I won't starting on my cart till the autumn. But happy to go with an order sooner to make up numbers.
Thanks very much.

I have been following the progress on/for sourcings sets of springs with interest, having bought a set from Jones Springs last year. However I have recently found a company who supply springs for trailers which look very interesting ( £14.26 EACH )
Now for someone who lives North of the Wall, THIS IS VERY INTERESTING!!!!!
I will attach a link below but what really draw my attention to these beauties is there dimensions being 50mm wide and perfect for the chassis steel of 75 X 50. I know they only have 1 eyelet fitting but this might be a bonus.
Anyway I thought I would put it out there and when I get a set I will let you know what they are like. One more point by the way, you can order up “U Bolts” & retaining plates to fit, no need to “mix and match”.
The springs are “Towflex” so may be sourced from other places in the U.K.

Take on board what you say about the weight rating but it was my intention to reduce it from 2 to 1 leaf.
As for the width, when you use the Jones Springs you need packers welding to the frame rails whereas these may only need a washer either side.
Anyway it’s an option for anyone on a budget after all you would be saving £80 + with a little extra work to fit.

Just circling back on this topic.
I had a reply from the pony cart company, their spring supplier can make the leaf springs we desire.
However the cost is excessive £280 plus.
Has anyone found a leaf spring source at a good price?
I have contacted Jones springs, others may havre been down this route before, will post the result when I know.

How did you go about your spec for the spring? If you are happy with the spring rate was there a reference number.
My mum was from Yorkshire and I can confirm it passes generation to generation - love a bargain!

I haven't had chance to fit them yet and as this is my first Cyclekart I'm not sure what to expect as far as spec.
Hope that helps.

Historically we have made various enquiries in an effort to secure leaf springs at a better price in the UK. I am pleased to see that progress is currently being made with Jones Springs and Renegade Karts.
Mark Underdown has been working away in the background to develop a jig and manufacture suitable springs at his workshop and he has now found a subcontractor who can provide the heat treatment.
I was in contact with Mark yesterday and he states :
"They are going to work out at £45 each (£90 per pair) after the first batch I will have a better idea on prices, the biggest question mark is wastage of material.
Hopefully I will be able to produce them reliably without too much in the scrap bin.
I will have a batch done by the AGM hopefully around 5-7 pairs. After that we can just see who wants them and when. "
I'm making everybody aware of Mark's kind offer before anyone commits to a large order elsewhere.

Just closing the loop with the contact I made with Jones Spring.
They can provide a spring to the drawing supplied @£75 +Vat per
That includes bushes drilled and reamed to 12mm.
If anyone wants to go down this route the contact is Kevin,
The phone number is 0121 568 7575, delivery is around 7 to 10 days.
Renegade Karts haven't come back to me regards postage to the UK.
Looks like there are now have some UK options.

I rolled the eyes to take a .875" Delrin bushing. My fixture was pretty make shift, rather laborious to use and was only suited for a one time run. Would it be possible
for me to get a photo or sketch of the fixture that you came up with? I have no intention at 80 years of age of manufacturing springs for sale, this is simply for my own use.
I had my heat treater temper them back to 42hrc. and they have a 4" camber which I can adjust in the hydraulic press.
