cnicholson Posted February 25, 2012 Share Posted February 25, 2012 I am in the process of getting a quote to have my rear rotoflex hubs machined to accept the mgf modern bearings, to enable the use of rover 100 drive shafts. Does anybody else want any done for the right price, the more that are done at once the better as I will have to pay for tooling costs and setup for a batch anyway?Thanks Carl Nicholson Link to comment Share on other sites More sharing options...

Nick Jones Posted February 26, 2012 Share Posted February 26, 2012 He has been.....I haven't got any at the moment and my previous machinist has retired so need another. If this guy quotes sensible prices them I may even add some VLs to the batch.CheersNick Link to comment Share on other sites More sharing options...
cnicholson Posted February 29, 2012 Author Share Posted February 29, 2012 ok had the prices back....£60 per side if i can get 10 done otherwise for just my 2 it will be £135 per side!so is there 5 people who are looking to get vertical links milled at £60 a piece, or has anybody got a set they wish to part with that have been done?

Think I will do my own. Link to comment Share on other sites More sharing options...
99176 Posted March 1, 2012 Share Posted March 1, 2012 Exactly what machining is needed ? Link to comment Share on other sites More sharing options...

cnicholson Posted March 1, 2012 Author Share Posted March 1, 2012 I know it does not seem cheap to me either......but there is distinctive lack of machine shops around these days, the going rate was about £40 per side according to nick jones. I would happily pay for them to be done cheaper elsewhere.I have a template of what needs doing its just a case finding somewhere that will do it for the correct money.

Nick Jones Posted March 1, 2012 Share Posted March 1, 2012 Not sure we'll get down to £40.00 these days but can hopefully improve a little on £ 60.00.Mine were actually being done on a Bridgeport mill which I don't think is the quick/cheap method but that's the way he wanted to do it. I found that most of the places I spoke to about it (went to 6 places about this back in 2009) didn't fancy swinging such a knobbly object in a lathe. Some of them have the radius arm brackets permanently attached by corrosion in the bolt hole (doesn't take much) which makes them and even more awkward shape. Unfortunately good VLs are not common enough to limit to ones with removable brackets only.CheersNick Link to comment Share on other sites More sharing options...

Gt6s Posted March 2, 2012 Share Posted March 2, 2012 Right, had a rotoflex rear vertical link in the lathe today to see if turning it out for a MGF bearing is viable. Mounted in the chuck from the hub side I have very good grip on the link and it rotates without a clearance issue so boreing should be straight foward provided its not spun too fast. The bracket for the trailing arm would be better removed but bending it out of the way will do the trick. The only issue I see is that to cut a groove for circlip at the hub side it may be nessesary to turn the hub round in the chuck which may not be griped in the chuck as sucessfully, or maybe it can be done working through the hub from the diff side. either that or leave a step in place of a circlip which would be somewhat easier yet serve the same purpose.

Richard B Posted March 2, 2012 Share Posted March 2, 2012 I think its done with a step on one side and a circlip groove on the other. Link to comment Share on other sites More sharing options...

I do not have the bits or know the full details of work required, just checking out the posibility of doing these for myself in the lathe. Link to comment Share on other sites More sharing options...
Nick Jones Posted March 2, 2012 Share Posted March 2, 2012 Mine have a step in the centre and a circlip groove on the outside. You could use two circlip grooves if it suits the machining method better. You also need to machine the outer end down a little as the new hub is thicker.Don't believe it can be done entirely in one operation...... You have to be able to mount it the other way round also.Nick Link to comment Share on other sites More sharing options...

Nick Jones Posted March 3, 2012 Share Posted March 3, 2012 Yes, Josh was the first to go the R100/MGF parts route.Nick Link to comment Share on other sites More sharing options...
99176 Posted March 3, 2012 Share Posted March 3, 2012 Without brackets it spins up OK in lathe.Had to relieve some to clear CV's but would like to go MGf route now. Link to comment Share on other sites More sharing options...
