Welcome to here. Tried to took at the turbosport forum but couldn't get in (think you need to be registered). I gather it's a Ford thing? What are you both working on?
its a ford forum (you can view , click forums top right). im more interested in the "old school" especialy the mk1 escort im about to "restore". i used to live under the things with gas/mig but have had 10 years off so lets hope i (my back!!) can cope !! mike.
I registered for a look. Looks like a very helpful place.
You'll have no trouble with any kind of electric welding if you have already used gas. Gas is tricky. Much the same principle with electric welding but a whole lot easier to use once you've looked up the basics.
A friend sold a MK2 Escort on eBay a couple of years ago. Full service history and one owner from new. Went for quite a lot of money. It's good to see enthusiasm developing for the early Fords.
My passion is the good old MK2 Granada! I have one that is purely for track use that has at the moment got a 350bhp Cosworth YB lump in it.
It is my pride and joy. I need to start looking at body repairs as it is totally original with no welding to date but I know I will find if I look
I have just bought a Cebora 894 plasma cutter to help with cutting out bits and pieces. If anyone has any hints or tips on using this machine that would be great as I have never used one before.
My welder is a Clarke turbo 170. The reason I bought it was that the place I used to work had one in its maintenance dept and it ran for 7 years with only tips, shrouds and liners requiring attention/replacement. I have had mine for 5 years now and can't fault it.
I have a contract with BOC for my gas. I HAVE JUST SET UP FOR ALUMINIUM WELDING - THATS BLOODY DIFFICULT AND FRUSTRATING. i WANT TO WELD UP MY OWN BIG WING SUMP!
A Cosworth Granada would explain your username. That must go awfully well with 350hp - aren't the old Grannies about the same weight as a new Fiesta?
I'm a big fan of the Clarkes. My 155T has been going strong for 14 years, and I have the original liner on it at the moment for alu welding. It's not a perfect beatie but all the problems have been bodgeable.
What's your trouble with alu welding? Have you seen the all I know about MIG welding alu page? I've managed 2mm using the Clarke (with some difficulty), but understand it gets easier as you get thicker.
Aluminium welding seemed like I was welding at 90mph. It was extremely hot and wanted to hust completely melt the 1.5mm piece I was welding. The next project is to weld 4mm plate to a cast alloy sump on my Cosworth engine. This will be a little easier as it is thicker. I will just have to weld in short bursts.
TBH I didn't really manage anything as it was just set up to see what it was like. The strips I had to practice one were just melted away really lol.
Do you think that I still need to heat sink using 4mm, bearing in mind that I will be welding it to a large alloy casing. I will, as I said, tack it initially and then rotate around the piece tacking a bit more & so on.
I have no idea - I've only ever tried 2mm and the heat sink made life a whole lot easier. I've heard people talk about MIG welding 10mm aluminium being an acceptable procedure, so I guess you don't need a heat sink for that thickness. Someone else might have tried 4mm, though you should be able to get away with it without a sink with short runs - that was my initial approach with 2mm and it worked but wasn't tidy. Trial and error unless someone else has experience of that sort of thickness.
