Hi all Ihave been trying for to buy 10mm 1.5 threaded nylon rod in 3 meter lenghts or something very near 3/8 16 maybe in 8ft so`s I can bartelise my Dob can any body help.
Try to find plastic rod and make your own thread, you can speed up the process by using a hand drill....
I remember seeing webpage ad for nylon rods sometime in the past.. if I remember I will let you know.
Also, PM on other details sent....
Try coventry group, like universal fastners, they usually stock Nylon threaded rod. Another company I went to here in Adelaide was United Fastners, thats where I got my 12mm threaded rod from.
Specialty fasteners in Canberra is pretty good. Try them. Bunnings will charge a fortune. Steel suppliers (Big ones) will give you a three metre length for a fraction of the price that bunnings will charge for one metre.
I have some mild steel Zinc plated threaded rod at home in 10mm and 6mm if you need a few short lengths.
Yours for nothing if you can arrange post or pickup from Canberra.
Well, if your horizontal drive wheel is 1/2 metres in diameter, you really need only a bit more than 1.5 metres (2*R*PI)...
Also, some people cut the thread in the plasticified edge of the wheel using hand drill and standard tap, I saw it made and it is easy, provided the job is properly prepared. Or, the thread can be impressed into the edge of the wheel, filled with epoxy resin. The possibilities are countless....
Trying to do the same thing and after exhausting local suppliers with no luck, I have come up with the idea of using the nylon joiner piece out of tung and groove.
used to use this for routing cables through wall cavities, and is very available anywhere.
as to laying a thread into it, I will need any advice I can get.
I got 1 metre lengths of 8 mm and 12mm nylon threaded rod from a local supplier in Seaford. If you let me know what you want, I'll try and get you some. Is it for a bartlised dob?
