Oh ok Rob,but can the pin not be straightened perhaps? If not it can be filed flat and then drilled and a new pin fitted, if you cannot obtain new from Wittners.
Also as I am seeing the drawing, it appears item 14 (the screw) is what engages with the Ratchet pin through the hole of the otherwise blank support disc in order to drive the back disc and then the hub spindle eventually.
Is this incorrect?
If so, A/ What job does the screw do?(item 14) B/ What does engage with the actual Ratchet (18) if not the screw? C/ What is the solitary hole for in the otherwise blank Ratchet Support Disc?
As I say Rob, this part of the machine is something completely new to me as I have never had reason to investigate any section of either the front or rear drive clutches or indeed, Ratchet mechanisms so far, so I am learning all the time with this one.
Also Rob, if you look again at the drawing, I am certain it shows the disc and ratchet the opposite way around to your photo.
From the drawing the long part of the centre tube and bore with the flat on it points out whilst the ratchet is on the inside of this same support plate.
Your photo shows the tube with the flat on it, on the same side as the ratchet (18) not as opposites as the drawing suggests.

Hi Paul, I know what you're saying, but £37.00 isn't the end of the world if it fixes the problem, and to be honest, I'm no engineer, so if I can remedy this properly without huge cost then I'll be happy.
Of course, I would have to think very hard about spending 100 euros per part for the other components, but I think it will work without replacing them as they are just slightly worn as opposed to worn out!
Andrew has a point; I'd like to keep the projector within it's original design if I can because, well, I'm kinda fond of it!
But seriously, the take-up does need quite finite adjustment on this machine. Too much tension and it can possibly damage film at the start of a reel, by pulling the spring loaded guide roller too hard; the film can then touch the base of the lamp house. Too little and by the end of a 600ft spool, you have film sagging.
Basically, it's hard enough to get the tension right and consistent with Beaulieu's original parts, let alone start replacing them.
That said, thanks again to you guys for all your help and support with this.
I'll let you know the outcome when the ratchet arrives...it's on the way now...
And if it doesn't work I may just paint it red and use it for display purposes only!!
PS. Andrew, I saw the new prices for the spindles! Wow...

Hi Rob, The snap ring needs to open up to locate the larger ring to fit the groove in the shaft to hold all them bits in place?. Try this mate, get a drill just large enough to open the smaller hole, maybe a 2mm or 2.5 mm, carefully tap the plain end of the drill into the small hole on a flat surface, this will open larger hole maybe enough to get it in position over the slot in the shaft, obviously use the drill has an handle to hold this, once in position remove the drill, this will then snap shut in the groove, perhaps a pair of long nose pliers would be handy here, to hold the ring while you remove the drill, as it may fly off.

Thanks Andrew, although in a moment of inspiration (or desperation!, maybe) I remembered that we had a pair of small nail scissors in the bathroom with slightly curved, pronged ends.
Perfect!
Snap rings back on and a quick test...well, I'd also swapped the front ratchet support discs to the rear arm, as they were like-new.
Rear take-up working great!
Front ratchet...not! Just occasionally, you could here it slipping. So, took it apart again (groan) and gave the worn ratchet support disc a few coats of Hammerite Silk over the last few days, to build back up the worn surface.
Finally got it all back together this morning and all seems well! Hurrah.
For anyone taking these arms apart though, be really careful when reassembling them as they are so fiddly and precise.
Very pleased that the Beaulieu is finally up and running again, and at a cost of under £40.00, not the end of the world...although I don't want to see another snap ring in a very long time...lol...
