Ah the fun and games of "generic" CAD formats that are anything but. I often have similar issues at work as we use Creo (formerly Pro/Engineer) and if we have to sub out design work it is often done in Solidworks. You'd think you could get them to talk to each other nicely, but Solidworks loves to generate garbage geometry... ..more likely the "draughts man '" that generates the carp geometry than Solidworks. I have had carp geometry in almost every format available. Put it down to people not knowing what they do. Surfaces that are trimmed to the wrong plane are always good for a laugh, but simple geometry where you have 37 duplicate lines does my head in. More often than not, the amount of time I spend cleaning other people's drawings, would be quicker to draw it myself. Only if you machine off a drawing will you understand the frustration on not being able to get a contour to chain as there are lines upon lines,arcs on top of arcs and branch points left right and centre..... Yes very true, ...Creo has some really nice analysis tools to find and fix the dodgy bits before we send it to the toolmakers, but they are often ignored. For the type of stuff we do Creo does generate much more stable models (lots of free form surface modelling) that's why we pay the extra for it. Spending an extra few days at the end of the project checking draft angles, wall thicknesses, interferences etc is a lot easier than machining out big lumps of injection mould to fit inserts, and our moulders hate finding big lumps of weld corroding from inside out after they have run the tool for a while. Better to stop the issues at source.

That is sub zero cool. It does mean you can only dress in a pinstripe suit, trilby hat and carry a tommy gun around with you at all times though.

Stick a little RAF roundel on the left front corner of the bonnet and some made up RAF serial numbers down the top of the wings and that would look right at home next to a Vulcan!

I'm going gas with mine, BOC do a deal for hobby users called the "Volkszone" deal, need to give head office a ring (details are on the mig welding forum) but it works out about a pound a week to rent the bottle then about £35 for a refill. I was tempted by the rent free offer from Adams Gas as they are local to me but when you consider the BOC bottles are twice the size and charged to nearly twice the pressure, you end up with something like 4 times as much gas for only a couple of quid more.
Just had a look and the contact details are :
Stuart Anderson, Gary Moorhouse, Krystle Smallman and Danielle Martin on 0161 930 6014

Might not be a good idea using actual sand, afaik sand is banned for industrial use as it causes silicosis, which is pretty nasty. Companies advertising sand blasting use various other types of blasting media like crushed glass, walnut shells etc. If you're using sand make sure you have a decent mask on :-)

I'm sure the R-tech will be a great little machine. Can't wait to get the Portamig fired up and laying some beads. But as always in these things "project creep" has led to the whole garage being re-wired with better cable, lighting and sockets, so need to finish that before I can crack on with glueing metal together!

R-tech seem to import Chinese machines and supposedly change a few bits inside and make sure they work porperly, but I think they upset the mig welding forum a while back as one of their employees was bigging them up on there without saying he worked for them. Meant to have very good aftersales service but virtually identical machines can be had in a different colour case for quite a bit less money. You're paying for the warranty I guess.
The GYS 162 gets good reviews for similar money. Transformer based rather than inverter so possibly going to last longer. I was in a similar situation recently and picked up a second hand, barely used Portamig 185 with euro torch, 95% of a spool of wire and gas reg for £400.

+1 for silver, black will make them look like the wheel trims are missing :-)

Pretty sure the E34 uses a very similar front suspension setup to my E39.. in that it has double lower arms rather than a conventional lower wishbone to control the side/side and front/back motion of the wheel, which work together with the track rods to create a "virtual" steering axis with better geometry that is further out into the wheel than would otherwise be possible with a normal lower ball joint. It might be that this means the forces on the front wheels act in a different way to what your used to.

yeah thought it might be a silly idea- was just based on the proposed layout, couldn't think of much else rear engine and 4wd apart from Porsches! ![:)](//storage.proboards.com/forum/images/smiley/smiley.png)

A bit left field but what about a VW T3/Vanagon Syncro gearbox? If you're not dead set on using the cossie engine you can get bellhousings for them to use Audi and Porsche engines (e.g. 944 lumps) and Subaru engines too.

No offence but don't touch knock off dremel tools with a barge pole. I tried to save money with some and every single tool either broke out flat out didn't work. For cutting discs get the speed click discs, good thing is they sell them in bnq if you're caught out. The discs arnt fast and they don't last long but they are very helpful for tricky spots or small cuts. Just remember let the dremel do the work, don't lean on it. Used those exact discs to cut off 4x m10 exhaust down pipe bolts last week, very limited access otherwise I would have used something with a bit more grunt, they worked great. As you say, not the fastest and don't lean on them but they did the job. Used a disc per bolt but they're dirt cheap. Have used the Dremel equivalents that were supplied with the Dremel set and they don't last any longer but cost 10x the price. I do agree though some of them are curse word, have had carbide grinding wheels that have lasted seconds or the little wire brushes just explode, but those cutting discs I linked to are decent.

The only ones that annoy me are the "you can do mine next" dog walkers who feel they have to comment about me bothering to clean my own car. Got pretty lucky with neighbours- my immediate neighbour who I share a drive with so the one that matters is sound- always comes out and pulls his car up the drive to give me more room if I'm I'm working on a car, and his son in law is a mechanic and occasionally does cash in hand stuff on our drive, which is cool with me, he has leant me tools and given advice if I'm stuck.
The guy opposite rebuilds gearboxes for a living and has a wicked little yellow nova he tools around in. On the little estate we live on we have a great Facebook group and a fair few guys on there are into cars, a few classics and 4x4 types. Great if you're stuck for a funny sized socket on a Sunday afternoon and every where's shut- quick message on the Facebook group, put the kettle on and 10 mins later some bloke from round the corner will turn up with a T60 Torx socket :-)

Just drill the end off, it should be a countersunk head so you only have to drill to the bottom of the taper and you'll be able to take the disk off. Then you might be able to grip the threaded part of the screw with mole grips and get it out without having to drill right down into the hole in the hub and risk wrecking the female thread.
Get some decent drill bits, take it slow and use lots of lube ;-) Had really good results with Heller Cobalt drills from Toolstation, got all 4 M10 exhaust downpipe bolts off my BMW with them with no snappage or blunting and they're made of 422 stainless.

Makes you wonder how it's been getting tickets all these years! That hasn't happened in 12 months! Shocking really.
The old Abf was a quality lump, got one in my passats day it goes really well, will be brilliant in the lighter Jetta. Better low end torque than the 1.8 kr but still revs out just as well at the top end. Are you going carbs or Fi?

The spreader is just the spring that holds the pads off the disc, looks like you've already got that bit off ![:)](//storage.proboards.com/forum/images/smiley/smiley.png) To take the caliper off there should be two M10 bolts that go through the caliper in to the back of the hub, then to get the disc off its just a case of undoing that little cross head screw in the front of the disc. Might need an impact driver for that...

20" wheels are standard BMX size - a modified Raleigh 20 / Shopper is a wonderful thing....... ![](http://i10.photobucket.com/albums/a133/kerrywh2001/5808388177_5d6f19b618_b_zpso9bc5jq8.jpg) Love that! Looks like a mini version of one of the bikes Greame Obree used to ride! ![](http://2.bp.blogspot.com/-srXqreV2Qfw/UQ2UgBSJXlI/AAAAAAAAB9M/iGJSCpAhWsU/s1600/Obree1.jpg)

Haha- reminds me of seeing an old yellow B1 Passat fastback at a show a few years back that was sitting really nice and low. when I asked how he had done it, he replied "spring clamps"
When I had a look, there was indeed a set of Halfords spec spring clamps wound right up on each spring :-O
I'd like top think he took them off before driving home but I'm not convinced he did.
While the Audi front suspension is the same as a Passat, I think the rears are different- the Audi used a coil spring-over-shock while on the B1 Passat the shock and spring were separate. B2 (type 32) Passats used a coil over shock but the axle beam is different to the Audi.
