Rope size

[Ricko]

Hi,

I hope you're all keeping safe.

My son and I are restoring a couple of stoves as a lockdown project (Coalbrookdale Little Wenlock & Hunter Hawk 4).

How do we calculate the rope size for the doors? Do we simply measure the channel?

Do the rope sizes refer to the stretched diameter?

Cheers

Best way is to search and see if diameter is mentioned,  its not measured stretched.

Don’t think you’re being clever by using the size up to get a tighter seal. I did and I got a worse seal.

Measure the diameter of the rope coming off,  bear in mind that this is usually oval shaped with wear,  it started round so average out the readings,

 

Be aware that now there is "hard' and 'soft"ropes in all sizes.   Older stoves ( Morso excepted) usually fitted hard ropes.

 

Usually there is no adjustment at the door handle to allow for a new rope,  the tightness of the joint is set by the amount of adhesive under the rope.

 

Procedure:

 

A,  Set a fire in the stove,  kinding and a firelighter at the front and a couple of half size logs behind them,  DO NOT LIGHT.

 

B,  Note where ends of rope are on the door,  write it down.   Remove old rope,  measure diameter in both directions,  measure length needed,  then add 50 - 75mm.

 

C,  Use a wire brush ( ideally on an angle grinder) to remove all the old adhesive in the rope groove,  this will have set like concrete and may need a persuasive tap to get out.

 

D,  Put a THIN bead of rope adhesive in the bottom of the rope groove.

 

E,   Press new rope into groove but dont pull ( stretch) it,  seal ends with high temp rope tape if poss,  if not cover well with adhesive.

 

F,   Shut door and fasten door handle.

 

G,  Open door,  remove excess adhesive from front of stove body and around rope itself.

 

H,  Light fire within stove and SHUT THE DOOR.   I know you dont usually shut the door on lighting but this time do so.   Once the fire gets going the heat will cure the adhesive in about 30 minutes.
