![]() 814 forum posts 36 photos | My letter in the latest issue of MEW (153) asked about creating 60 pulses from a 65 tooth gear in the lathe. Since writing the letter I have been trying to answer my own question by delving into the internet and using an electronics forum. I have been told about an interesting chip which can be used for this (CD4089BE) and using two of these chips cascaded in the add mode provides the correction needed to a very acceptable degree of accuracy (about 0.1%).I found a supplier of these chips on ebay and am waiting for delivery.
I still feel however there may be a simpler electronic solution so if you can come up with one lets have it. Douglas
