Grampian Type D - Reconditioning
Hey trolls
I have a Grampian feedback cutting head - type D
and i would like to recondition it - i have the original manual, which i will scan and upload to the repository if there is not already copy.
Wherein it refers to some items and materials that Im hoping someone with some insight can suggest modern equivalents
They are:
Silicone damping fluid - 'Dow Corning'
Absorbent washer
Sealing pads
Spacers
Cement - 'Goodyear Plio-bond'
I have the original of all above except the cement - i imagine they should be replaced, if there is a ideal solution.
The rest of the instructions are relatively straightforward, but if a troll out there knows of any tricks
Im all ears.
Cheers

ps. a couple of photos attached of the components as they were once removed.
pps. Im very interested in matching a Gotham amplifier to this - if anyone knows of where i can get one - please PM

Would be interested in grampian D manual
Is possible to get copy? Or where to find?

If you successfully wind a new saddle coil for this, I would be interested in buying a few. I don't have a coil form for it. Thanks!

Nice, I'd be interested in the manual too!
Re: Grampian Type D - Reconditioning
I have the manual for this head; will scan it and post when I get home from work today.

Sorry this took so long; here are the two pages of the tech literature that came with the Grampian head:

Re: Grampian Type D - Reconditioning
Hello,
I wounded saddle coils, for grampian replica, and is not really difficult. You have to wind them round first, around a cylinder (I used a marker) and with two rubber stops away from a 3mm gap. Then wind first the feedback with the thinnest wire you can get, and then, around hundred turns of thicker wire for the drive coil, When is done, carefully remove the rubber and tie around the coil some Teflon strip, or alike to keep the turns together.
Then bend it to a saddle shape around the armature. If is too big or too small, try with other cylinder diameter. Check resistance of the coils, and change number of turns or gauge if needed. This may take the whole afternoon, dont worry, relax and enjoy.
The "sweet spot" of resistance/gauge/number or turns ratio is wide, it don't have to be exact. Its more important that the coil fit perfect on his place, and don't protude too much outside the pole pieces, this will cause a big waste.
I'll try to find pictures, and check wich gauge I used, if I find n my notes....
