EAF Standard Bolts Too Short for Explore Scientific APO EDT Series Rack & Pinion Focuser

Post by fatboy1271 » Fri Aug 30, 2019 7:03 pm

I purchased an EAF Standard yesterday at my local camera/telescope store! I was so excited to get it installed; however, the M4 bolts on my focuser are recessed and all of the bolts that come with the EAF are the same length as what's already in the focuser. I went to a hardware store and purchased 4 different length M4s. I will try them out tonight to see which length works best.

I ended up using M4 x 25 and two washers: an original washer from the focuser and one washer from the EAF kit. Everything is working great now!
