Hi Guys,
Sorry for late reply.
Yes that is the right P.I.E.S.
The pulleys are not very expensive and they have a web shop.
In fact it's better to buy from via the web as they give a better price as I found out the more expensive way by going to their office.
The prices are on the web. Typically $17.00 fot the 60 tooth and $11.00 for the 15 tooth.

I have got some PE traces but they show some runnout in the 60 tooth.
I just machined another one to try to get it more accurate.

As soon as the rain stops and I can see the stars again I'll get some more data.

I captured 8 worm cycles and the data showed the benefit ofg the 4:1 ratio pulley ratio.

I had a peak to peak PE of around 15 arc seconds but all cycles are perfectly in phase and EQASCOM's REC works a treat.

I think that I can do better with the second try at the 60 tooth pulley.
Also I need to lapp the worm/worm gear combo a bit more.
I got a replacement worm from Aeroquest and it needs some more work.
Not very impressed really. It is a bit better than the Synta one but that's all.

I really very happy with the mount now. It is very quiet compared to what it was. No rattling of gears. Just the musical tomes of the stepper accellerating and decellerating.

Since the EA axis turned out so well I decided to do the DEC axis as well and I did that today.
Now I have a totally belt driven EQ6.

I highly recommend it to all EQ6 owners.

It is a vey easy mod to do. and for those who don't have the machinery, you can achieve the same thing with the smaller 2.0 mm pitch pulleys and 4mm belts.
Apparently there is no machining required and they will fit in the housing.
So I have been told.

I wanted something a bit more substancial and so I went for the 2.5 mm pitch and 8mm belts.
200mm long belts fit nicely without and need to modify the motor mounts.

I'll be very interested to hear if anyone else does the same as me.

Cheers,
Luke
