Bowie69 Posted January 12, 2022 Share Posted January 12, 2022 That, my friend, is what is known as fabricobbling. Excellent work, really excellent, and love the use of a release bearing. 1 Quote Link to comment Share on other sites More sharing options...
steve b Posted January 12, 2022 Share Posted January 12, 2022 The grinder extension is rather inspired too , nice to see you back in action although I'm not sure this qualifies as taking it easy Steve 1 Quote Link to comment Share on other sites More sharing options...
elbekko Posted January 12, 2022 Share Posted January 12, 2022 That is seriously impressive, once again. Just casually making your own custom pneumatic cylinder, sure, why not 1 Quote Link to comment Share on other sites More sharing options...

steve b Posted January 12, 2022 Share Posted January 12, 2022 Agree entirely . You shouldn't need much pressure to operate that with the surface area . all very tidy indeed . Steve Quote Link to comment Share on other sites More sharing options...

Steve Once I've sussed out where to run the air pipe I will connect it up to my ARB compressor, and try it out again, think that will do around a 100psi so should be more than enough regards Stephen Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted January 12, 2022 Share Posted January 12, 2022 What do you reckon the surface area of that cylinder is then? I can't imagine that dog needing much force to get it to engage. 1 Quote Link to comment Share on other sites More sharing options...

I can't imagine that dog needing much force to get it to engage. By my calcs and I'm carp at maths I make it around 2900mm/2, the spring on the dog is quite stiff as it needs to force the dog to disengage when switched off, when I bench tested it it would not work either way if alignment was out regards Stephen 1 Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted January 12, 2022 Author Share Posted January 12, 2022 A question for the parts gurus please can anyone tell me the part no for this release bearing I have two others but there is differences and I'd like the same one please to make my other cylinder with thanks in advance regards Stephen Quote Link to comment Share on other sites More sharing options...
miketomcat Posted January 12, 2022 Share Posted January 12, 2022 It's frc9568 however it's supersede by ftc5200. You do not want ftc5200 but many suppliers will send it instead. Mike 1 Quote Link to comment Share on other sites More sharing options...

miketomcat Posted January 12, 2022 Share Posted January 12, 2022 I have a rakeway HD release bearing that uses the bearing off the type you showed hence I know they just press off. I had a job finding one when I changed the gearbox recently. I had a crumble at a supplier that listed the correct number and picture but still sent the later version. Several suppliers have the early one pictured but the later part number. Mike Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted January 12, 2022 Share Posted January 12, 2022 ISTR there's two very similar ones, FTC5200 and something else... one has a slightly deeper carrier than the other but for your purposes it shouldn't matter. The cylinder is really cool - I think I must've missed where the return spring is hiding? 1 Quote Link to comment Share on other sites More sharing options...

Stellaghost Posted January 13, 2022 Author Share Posted January 13, 2022 (edited) Not much done today , this air delivery conundrum was doing my head in so moved onto some other stuff not axle related I've ordered some bits and pieces but perhaps one of you bright chaps may have a solution This is what we're working with decided not to solder copper in but going down this route instead, caused me an issue because my original hole was too close to bore that halfshaft slides through so I redrilled and tapped out, was a pain to drill as welding had hardened it somewhat air pipe is what is supplied by ARB when you get lockers so I need to go through axle cases as do not want to interfere with bushed and cast ends, pipe needs to stay tight to inner bore and then turn 90 degrees through casing all whilst keeping pipe from rubbing onto halfshaft and wearing through, I have a couple of things in my head but someone might have a better idea, or has done something similar in the past thinking caps on chaps regards Stephen Edit, forgot to add it all needs to be removable in case seals fail on pneumatic cylinder Edited January 13, 2022 by Stellaghost Addition Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 13, 2022 Share Posted January 13, 2022 Is there scope to connect to the cylinder from the side? That way you could go straight through the axle case, copper washer for sealing and done? Quote Link to comment Share on other sites More sharing options...

It's certainly worth looking at, would need to be extremely accurate drilling and I would have to modify piston possibly( very slightly )to accept air from the side, could drill and tap piston body to 1/8 bsp and tighten a pipe in from the outside of axle case, food for thought thank you regards Stephen 1 Quote Link to comment Share on other sites More sharing options...
cackshifter Posted January 13, 2022 Share Posted January 13, 2022 I wondered if you could make an annular groove in the outside of the cylinder, with a couple of O rings either side to seal it. Then you just need to connect through where the groove is. You'd have to plug the end where it is currently connected and drill from the annular groove into the feed. Or maybe I'm missing something, forgive me if so. 1 1 Quote Link to comment Share on other sites More sharing options...

Or maybe I'm missing something, forgive me if so. Nothing to forgive good suggestion and I will file it away for future use thank you So I've ran with @Bowie69' s suggestion The bottom of my cylinder is 13mm thick so I've managed to drill through into this and the original hole so I just need to plug the inside thread now not 100% accurate with the drilling but it mates with existing hole so gets the job done, will enlarge the two axle case holes and make a pin on the lathe that will screw into cylinder base and also outer axle tube, then run my flexi pipe from there to compressor, thanks for the suggestion Peter regards Stephen Quote Link to comment Share on other sites More sharing options...
Wytze Posted January 13, 2022 Share Posted January 13, 2022 Looks like a good solution. It will secure the cilinder aswell Quote Link to comment Share on other sites More sharing options...
cackshifter Posted January 13, 2022 Share Posted January 13, 2022 I do think you might need more than that to secure the cylinder. On the bench fine, but under battle conditions it might get tossed around a bit, the dogs might put some force on it etc. Quote Link to comment Share on other sites More sharing options...
