Hello Gents,
Ordered a set of springs from one of our suppliers and arrived in fine condition. Although they do not match the profile of the originals.
decided to take the packs apart and clip the edges of each corner to the original 30 degree angle. Also have decided to go the extra mile and have all the springs engraved as per original engraving B.S.G. APR 1933 an attempt to get as close as possible to original.
Plan to either Teflon them or paint with Slip Plate after the work is done. I would like to keep them dry as with grease they tend to gather grit and wear.
It was interesting to me that each of the leaves was engraved with the above.
Kindly,
Brian W Sullivan |

Why not engrave them with the same text but the year 2017.
That way the next owner has no doubt about originality and you are as close to it as you can be

The original marking is not engraving but stamping, probably done hot before the springs were formed and tempered. Engraving may well look a bit artificial, however well done.

Morning Brian,
My Morris McEvoy Special springs were also forged in April 1933, but by William Cary. Perhaps B.S.G. refers to Richard Berry and Son?

Belay that - it is the British Springs Group. Just found this post by John James back in 2012:
"The original supplier of J2 springs was BSG (British Springs Group) of Brignorth, Shropshire. The ends of each leaf were properly tapered.
'Berry' i.e. Brockhouse Berry of Manchester must have arrived on the scene later. They were the original supplier of springs for the TC.
Regarding lubrication, you need to coat between each leaf with a mixture of graphite and silicon grease or waxoil; The graphite lubricates the springs, whilst the silicon grease/waxoil prevents water washing away the graphite mixture.
A horribly messy job, but well worth doing."

I notice your new springs have square ends, whereas all of the original MG and Morris springs were tapered. You might consider tapering the leaves on your new springs if originality is uppermost in your mind? |

1930's Teflon? Sticking at nothing for originality?

I'm just doing some springs for a TA Tickford and through research on this forum, found the recommendation for MolySlip OGL (open gear lube) as a lubricant. I can only find the spray in the US, not the tub, but it is reputed to be resistant to washing away and quite slippery.

I wonder when we use replacement parts on our cars should all of them be marked? What about marked replacement Lucas badges, and other parts. I see some have altered replacements to include new information as to originality.
Re lubricant. The machine shop near me has been making parts for Morgan with engraving. The new springs he has done have been Teflon coated. I was advised by the high level restoration shop near me to use a product named Slip Plate. They do this on every car they restore.
Ian ,
Yes I intend to clip the corners on all the square ended springs as per original.
And perhaps even add 2017 engraving.
Kindly

Oh
Yes the originals were certainly pressed into the hot steel. There is no way I would heat the spring steel and do this though. So best aproach I thought was engraving as opposed to etching or sand blasting the marks.
Kindly.
