Jim, There are a few different grades in the black as well, you need the one that turns off like cast iron turns, a bit powdery, some will absorb oil or water and swell. How do you reckon Phosphor bronze would stand up to the load?
Cheers, Ferret.

Crikey Ferret , you must be a mind reader was just now scrounging around in the scrap bin for a piece off-cut of bronze-- reckon it would be bees knees. Since retiring I have really enjoyed getting back at machining really shows how much you don't remember ( left m/c shop 1973 -- mec eng & mining eng then till2005 ) looks /sounds as though you are at it professionally & do some design/fab as well. What type work do you do -- is it similar to Tony . All on hold till I get sample part from Tony. -- have you considered constructing exchange service in WA.? -- May not be feasable for some of reasons as you alluded to in previous post. The Black that I have turns beaut but still runs a stringy swarf so it must still be a grade or two softer than optimum -- will call by old shop & see what offers there. Cancelled my professional indemnity in surance 30 june so no more charge out jobs for me .-- still do some design at arms length ( pays for toys etc. LOL. )-- GREAT SITE THIS --soooo helpful & participants are so generous of spirit . Regards Jim.
Hi Jim,Nah, my days under the bonnet are long gone, I just work on my invention, The Ferret deflator.
I also make light brackets and bibs n bobs, use the lathe most days, lots of welding etc and hang'n out on this forum,
Yes they are a great bunch on here fer sure.
By the way, phosphor bronze is self lubricating whereas normal bronze isn't, but as a machinist, you would know that.
Don't be misled by the soft swarf on the acetal, it'll take a finger off as quick as stainless.
Cheers Rod.
G/Day Rod, Yep up to speed on the bronze - used to spec as seals on hyd cylinders ( 900 ton) in coal mining .
O/T do lots caravanning & have discovered a design fault in the suspension system as used by thousands of vans ( happened to mine) so dropped it into repair shop ( van specialist ) & was alarmed at the proposed repair technique -- stopped the process , enquired as to why a much simpler & hugely superior fix was not used& he said that they hadin the past, tried to accomplish the repair, as I wanted ,but in so doing had about 12 shop hours invested so aborted & just went with the accepted fix. could not accurately drill necessary holes) -- I held repair over pending solving his problem.
I have subsequently designed & am in the process of building a jigging system to do the job properly -- will have working prototype next couple weeks ( been into house renos last 8weeks ) & he will test run on my van -- if successful I will build a few & sell to selected dealer/repairers.
Where I am going with this is that you may be interested to build a few & add to your inventory-- just keeps the m/c's going & when on the move can call on a dealer/repairer or two ,keep ya young !!! ha ha -- I don't want any $ would get satisfaction that poor unsuspecting van owners are getting propper job done ( there are literally thousands on the road who don't know why their tyres scrub or springs are breaking !!! yikes -scary to me -- will keep u posted on result of test run. BTW thought Tony may be interested - his dad can knock up the jig & he can go from there.
Regards Jim
Hi Jim, I would be interested in the workings of it, altho I dunno if I have the time to build them.
You could register the design and sub them out to a Machine shop/fabricator.
Don't flash it around at all as you may need to patent it.
Cheers Rod.
Hey Rod. Been down that patent line in another life -- but as I said if it works as expected ( i'm sure it will ) only too happy to pass it on to deserving persons especially if will be of benefit. M/C is simple -- only one piece of precise turning but a miller is also reqd to dress one face -- could do it on larger ( big ) lathe & flycut. Really just enjoying using owm m/c's &solving the problem. Regards Jim
Rod , an off topic but of interest -- was nearly a close neighbour of you -- bought canal block in Sth Yunderup abt 6 yr. ago to be closer to my kids (Perth & Albany ) but I could'nt get a builder to start on construction for 2 years & would not fix completion or final costing -- what a schmozzle so we ditched the idea & sold the block . Was looking to catching all those crabs from my jetty . Small world really. Catch ta later Jim.
claw45, I sent you a pm, have a look. Cheers
Well, tie ma face to an ant hill and smeer ma ears with jaym, small world,Quote:

G/Day all -- Quick update -- made some replacement bushes today -- the unit appears as new -- the material was supplied by another member but as I recollect it was Nylatron -- will make some more from Acetal nuw that I have reqd. dimensions. Jim.
PS. this is in no way a major refurbishment .. just need access to lathe. ( provided journals are not worn.)
