Astro_Al Posted April 17, 2008 Share Posted April 17, 2008 Al is either pulling your leg even more or has eye sight problems The brake line protector welding though is carp Lara. Hold on - where did I say there was anything wrong with it???? Just asking about the technique, thassall! I know that on other forums 'stacked dime' welds have been a bone of contention. Will - its too late, we have the photographic evidence! Al. Quote Link to comment Share on other sites More sharing options...

I know that on other forums 'stacked dime' welds have been a bone of contention.Will - its too late, we have the photographic evidence! Al. Al you are a bad man........... You mean like an overlapping line of single spot welds ............ as opposed to a continuous (push) run........... Ian Quote Link to comment Share on other sites More sharing options...
Astro_Al Posted April 17, 2008 Share Posted April 17, 2008 Al you are a bad man........... I do it so you don't have to. Yes - an overlapping line of (effectively) cold spot welds. The only way to do it continuously that I know of is to make a 'pool', push forward over the second to where the third would be (letting the first cool), the reverse back to the second and make that pool, then push past the third to the forth while the second cools then back to the thrid to pool again - etc etc. Since this is effectively cooling the weld pool then starting another on top (which you need to do to get the definition, as far as I know, which isn't necessarily very far), the difference between cold spots and continous done in the above way is what? Is that how you do it Will? Just genuinely interested... Although I bet its not coming across like that! Al Quote Link to comment Share on other sites More sharing options...
upnover4x4 Posted April 17, 2008 Author Share Posted April 17, 2008 Pipe end caps - commonly used in water industry (how handy!) probably manufactured by Saint Gobain Pipelines amongst others. I'll have a butchers when i get back to the office for stockists as its gonna be much cheaper that way. Spoke to st.gobain with no luck... they did recommend somebody but no luck there either.

upnover4x4 Posted April 17, 2008 Author Share Posted April 17, 2008 What did they say...they dont make em, or they wont supply them (both are false!)?? They said they didnt sell them nor make them. Spoke to another company local to me in cornwall that Gobain said might do them & they didnt sell or know where I could get themeither. They did sell caps but no where near the size we require. I spoke to crown diffs tues & he has a friend who make them for him using pipe caps, but understandably wasnt willing to divulge the suppliers name.

Maybe its just they dont want to deal with joe public. Im sure theres enough people interested here to warrant a bulk purchase. I need 2 & probably might keep another 2 as spares for future needs.

smo Posted April 17, 2008 Share Posted April 17, 2008 Sounds about right - they are frosty at the best of times and we spend millions with them every year! I'll try and find another supplier who will be more accommodating. Is it 9" end caps we need? Quote Link to comment Share on other sites More sharing options...

Is it 9" end caps we need? Just measured the old oe pan & roughly 8". Looking at what jim gigglepin said that his over lap the originals, I would think 8 1/2-9". Worth seeing what sizes are available. Theres quite a lot of area the accomodate a 9" pan id say. Ill grind the old pan of in the morning to get a more accurate figure Ade Quote Link to comment Share on other sites More sharing options...
JST Posted April 17, 2008 Share Posted April 17, 2008 I have a prototype one from Southdown pictures below, the hole for the filler was slightly out hence the wrong angle on the crown wheel ridge, Davs presses them himself then they have a weld on lip, probably worth calling him if your thinking about them, he may do a special price for a group order - not sure?

Guest WALFY Posted April 17, 2008 Share Posted April 17, 2008 Is that welded on or clamped James? Quote Link to comment Share on other sites More sharing options...
JST Posted April 17, 2008 Share Posted April 17, 2008 Mark - welded in 4 places with sealant underneath to stop the water getting in. You can bond them on too though. Quote Link to comment Share on other sites More sharing options...
Guest WALFY Posted April 17, 2008 Share Posted April 17, 2008 Just concerned about the mud/water getting in the big hole where you get access to the filler plug Quote Link to comment Share on other sites More sharing options...
JST Posted April 17, 2008 Share Posted April 17, 2008 nope its got sealant around the filler hole so no gaps Quote Link to comment Share on other sites More sharing options...
Guest WALFY Posted April 17, 2008 Share Posted April 17, 2008 OK it's not clear in your pic though. It's of no use to me anyway, I've got an early RRC axle so the filler is on the diff . Still looking for a bare disk brake rear axle tube Quote Link to comment Share on other sites More sharing options...
JST Posted April 17, 2008 Share Posted April 17, 2008 So get one without the hole. Quote Link to comment Share on other sites More sharing options...
clbarclay Posted April 17, 2008 Share Posted April 17, 2008 Haven't got any pics, though I have just done mine the other weekend. I got some pipe end caps at £10 each from a local supplier (had about half a doven left over from an old order). Involved a little more work than some purpose built alternatives to get them just the right shape and fit the filler plug out off the origional diff pan, but thats all part of the fun for me. Also unlike some end caps (eg the ANSI cap) which can be 9mm or more thick the ones I got were made from handier 6mm. Quote Link to comment Share on other sites More sharing options...

Al Yeah, that's sort of it - rollback over the top of the previous 'weld' in a spiralling action. The big differance between a row of cold spots and this is that it isn't cold. Although you can see a pattern in the weld there isn't much in the way of a change in profile showing the liquid metal is flowing freely into and over the last spiral. If it had just been a line of spot welds you'd have a very blobby surface due to the surface tension of the individual welds. Quote Link to comment Share on other sites More sharing options...

Bull Bar Cowboy Posted April 18, 2008 Share Posted April 18, 2008 Like so? Not a strong method of welding and has the potential to create a cold weld unless a lot of care is taken .................. however, there is no strength required in a diff pan weld................ it just needs to be oil tight .......................so its OK............ B) I welded mine as an almost continuous weld divided up into quarters............. prep......... welded................. new spring seats............. But hey .................... just so that you dont get the idea that it always goes OK ..................... I lost concentration on the lower half and 'wandered' ......... I had to grind off and run it again............ That is a H/duty pan ................. not pipe cap h/Duty but then again I don't usually reverse into stuff at speed !
