Dear PTSPTS 寫:I am interested in where did you find this?PeterPeter 寫:當上門打聽天文鏡的到貨進展時,無意中發現到這個早期的香港DIY有電跟的赤道儀.
聽老闆講它的蝸齒有成三百多個齒. 真係想知到它可否與現代中型的mount較量一下.
From the photos, the polar axis is based on my earlier design : using bronze bushing as bearings, and a split bronze bushing as the clutch.
This must belong to one of my old friends.

I still keep 2 sets of this worm gear, one is double thread
and one is signle thread, both are 180 : 1 in ratio.
I believed that the mounting only seen part of the polor axis
in photo is belongs to Mr. Y.P. Kwan.
