thanks all
thats a good idea john ,so where do you get those screws ?
so those three are adjusters for the tilt of the secondary ?
whats the centre one a locking screw?
I have this chesire i just bought for $30 is there any way i can modify it to do both,I have access to a lathe and engineer to make most little things i might need

. As near as i can see with the secondary it is awefull close to being right.. but I'm not adverse to messin with something that aint broke.
again all thanks for your help
