Morning all, Wow almost 2 years since I last updated this thread! Quite a lot has changed on the Camera Panning Jig Thingy or CPJT for short.. The bearing wheels lost thier inner tube rubber tyres/tires as well, they kept losing them.. Despite a nice tight fit on the bearings they would work their way one way or the other and come off! String or fishing line was always a bad idea really.. The fishing line was a very strong one, I can't remember now what it was rated at) but it would still stretch and eventually snap! I didn't fancy it breaking when doing a vertical shot and my video camera hurttling towards the ground at a very fast and very damaging rate Soooo, now we have a whole lotta thread Let's start at the smaller end... That's the end of a rather long length of threaded rod with a "made on the lathe" thingy that screws onto the rod (with a lock nut) and allows me to put a bearing or two on the end of the threaded rod.. Yes you are seeing correctly, that is a skateboard wheel and bearings fixed on the frame The idea is the skateboard wheel allows for a little bit of movement which makes everything run a lot smoother. Moving along the threaded rod we come to the camera carriage thingy.. Zoom in a bit and you can see the threaded rod runs through a couple of nut's welded onto the carriage.. As the threaded rod turns, it forces the nut's to wind down (or up) the thread which being welded to the carriage moves the carriage along the rails... Cool eh A view from the underside.. The lead pipe is zip tied on to the carriage to counter balance the weight of the carriage and camera on top when the CPJY is being used vertically.. Otherwise know as up and down Moving down (or is it up?) to the business end we have a couple of pulleys a belt and half a wiper motor.. With the pulleys set this way the carriage moves down the rails at a ground breaking 1 inch per minute. The carriage has a little over 6 foot of travel along the rails which gives me a 1hr 12mins recording time as the camera pans it's way down the rails.. That may sound like a long time, but is is very handy when filming long scenes such as stripping all the parts off MadTrax If I swap the pulleys around then I get a total travel time of about 6 mins.. I have made a couple of other pulleys (no photo) which can be swapped in giving more travel time options.. A better view of this end, a computer cooling fan has been fixed on to help keep the wiper motor cool.. It does get a bit hot which I expect it did when it was actually being used as a wiper motor! Power now comes from a Mustang CB radio power pack.. No fancy speed control this time (as the pulleys take care of the speed), just forward and back depending on how the two wires are connected. The lengths (and heights) I go to to bring you all good video footage You can see al the "panning action" in the next MadTrax video, strip down in timelapse

it was marketing, before 74 they were 6 speed (with 2 reverse) after that they became 8 speed (inc 2 reverse)

Having a clearout and found this. Its a 3 HP Briggs, turns over with compression but no spark might be worth a tenner for parts ?

Quiet drive - Use the wiper motor ( with the plain bearings greased ) with a block of wood roll pinned onto the shaft .Fix a 1" plywood disc onto the block and stretch some inner tube over the disc to form a grippy tyre . Make a similar pinned block arrangement on the input shaft , just make a 10" or 12" plywood disc ( 3/4 or 1" ply ) and use a larger innertube from a van etc to make up the tyre . Mount the wiper motor on a plywood plate that is free moving ( pivoted ) so a deadweight or spring can pull the drive and driven discs together . If your motor is doing 45rpm , a 1" disc onto a 12" disc should reduce this down to 3.75 rpm .If the bar this drives is 1/2" then you should see a trolley travel of around 6 1/4" per min with the line fixed directly to the bar . If 12" travel a min is required then use a 6" disc and so on . If you have any , bicycle wheels make large diameter pulleys for a belt reduction , again almost silent due to the lack of grindy gears .And a inner tube can be cut length wise in half to make a good flat belt to be driven off a piece of brush handle fixed to the motor shaft . Or just make up a disc drive and run it directly on the inner rim . And iff all else fails , rob the little womens sewing machine motor and foot pedal .......

Thats right! we made a finger bar from a barford fit. It was a good worker but my brother thought the money would be more useful to him.
