I suppose it would be ideal if RTR could tweak each whishbone and brackets for each kit before they powder coated as they would also have the option of matching wishbones to a specific chassis, I can imagine making say 100 lower rear wishbones measuring them accurately then making a chassis measuring the brackets and choosing the wishbone from the 100 that fits the chassis the best, however i suppose this would be a bit time consuming and costly and would add a few quid onto the cost of the kit. These fitting problems should not be there. An accurate jig with each wishbone coming out of it within 1mm should be easily acheivable.

That's really interesting Kiwicanfly. I really dont have any experience of this kind of welding to know what tolerances are acceptable? my only knowledge is from some DIY plumbing, if i clamp 2 bits of copper pipe in the vice them solder them when you release the vice the joint often moves a few millimetres, presumably thermal stresses developing in the pipe and joint during heating are not uniform in all directions leaving some residual stress that is released and deforms the joint when it leaves the clamp ?? presumably there must be some formal engineering solution to this but maybe it's cost prohibitive ??

The company I work for has a foundry one of the worst processes for defects in that you pour molten metal into a mould and cannot see the true results of your work untill it has solidified, this could be many kgs of metal over many components.
If a defect is there it is bad news but the best defect is the one that appears in the same place in multiple castings, it means you can take steps to eliminate this because it is due to a specific cause.
If the components are put into a jig and the same defect keeps appearing, which seems to be the case here, you engineer compensation into the jig in order to eliminate the fault.
Hey did you guys see a pile of parts heading my way when were at RTR at the weekend?

I wonder if the defect is random though ie can be in any direction and so difficult to compensate for, i have a mate who is a welder i will ask him next time i see him.
There were loads of bits all over the place i didn't ask specifically have been following your thread on 'where in the world' so i thought they had already been sent or i would have asked, one of the guys was half way through building a rocket for a customer and jack and i spent ages picking his brain about various bits etc was really nice helpful guy got lots of useful tips.
Looking forward to seeing your build progressing
Jon

Actually thinking about when we where there a dodgy looking guy pitched up in an old van said he was taking some bits to new zealand and could me and jack help him load up the van so we did, he needed some help what with his wearing that mask to cover his eyes, had some big helpful bags which we used with SWAG deliveries on the side.

Well acording to Wikipedia SWAG means "Promotional merchandise, promotional items, promotional products, promotional gifts, or advertising gifts, sometimes nicknamed swag or schwag, are articles of merchandise (often branded with a logo) used in marketing and communication programs. They are given away to promote a company, corporate image, brand, or event." I don't know what branding is on the kit but certainly wasn't given away for free !

Wow! nice one! i like them, there like a proper statement piece! Have you got black panels? I did the same getting my wheels the same color as the chassis, not quite so bright though! lol. keep it up! wayne.

I went for black wheels and I am going to get my calipers coated at the same as the chassis (being supplied uncoated). I agree that the contrast is good.

Previously on Jack and Dad's build... the suspension didn't fit, so it was time to roll out the big guns... The official adjustment tool, and a crowbar to lever the suspension into place... The crowbar in action, a force to be reckoned with. I'm heavy enough then... And that's how its done. With brute force and a arge amount of elbow grease. Then, because dad broke the Press, we had to put the wheel hub on by putting a bolt though the hub and upright,and pushing them together with the nut, hence the spanners. and then we put the back wheels on, and I think it looks Legen... wait for it...

Hi to mabbs or anyone else I noticed in mabbs' thread that it looks like he has put a bolt through the rear wheel bearing whilst waiting to put the driveshafts in: I was concerned as i know this bearing is quite loose and i assume that it all tightens up when you tighten up the main nut on the end of the drive shaft i wonder if this is a good idea to stop it coming apart particularly if you put your wheels on (like i have ) and spin them around etc i'm worried the bearing is being held together by the oil seal, is this a good idea and if so where can you get the correct size washers ?

I am going to get my wheels on too and was told I can leave the bearing as is with no problems until I get the engine in.
Will be interested in the replies you get as I might have to do something too.

However, I've moved mine a fair bit without the bolt with no issues.
