MK Harness bolts
I noticed at donno that the threaded tubes for the harness bolts have been beefed up with some plate to create a web between the tubes and chassis. Is
this related to a thread i read on here about an MK Indy failing SVA because of this, altyhough Martin did speak to the test centre (and Swansea) to
sort it out? Just a bit worried about my older chassis that doesn't have it.

Hi Austen,
Just so happens I took a couple of pics of the mountings to show the SVA man as I think they will be covered up after I panel the interior.
I've put them in my archive, hopefully there of some use.
Cheers
Nick

mk harness bolts
It was my indy that was the centre of the seat belt anchorage contraversy back in June. Martin came to some agreement with Swansea to apease the
situation and the testers decision was overuled.
Thats why the extra "bridge" has been added, though i don't know how this will affect home built chassis. Again it seems all
down to individual testers and stations.

Redeye,
I think they drill out some round bar and then tap the hole to suit.
Cheers

Redeye,
Hold the round bar in a vice, and drill though with correct size drill bit.
Then run through with a tap.
You may find it easier to buy some threaded tube instead.

Be careful if you intend to weld it on (how else would you!) that the heat doesn't distort the thread, leave a bolt in it, this should
help...

All this tapping
... all this tapping? Have I wondered into a Fred Astair Appreciation Society or a Kit Car Builders Forum? 
Mad... sounds like you speak from experience!

i always found the best way to drill and tap round bar was with a lathe then when welding it in make a mushroom of modelling clay so that no weld
spatter can get in the treads once done pull out the clay and run a tap through the treads again.
the method with the bolt in can result in a broken bolt and then you have to start all over again but with the disadvantage that the thing is now
welded to somthing large and difficult to handle

I started the thread until I reached the end of the tapered bit of the tap. Then, after welding, I finished it off.

Don't get any of your bolts or nuts hot (unless you can guaruntee you'll remember to throw them out immediately), as they will
lose their set.
Heating up a grade 8 bolt for instance will render it about as much use as a stick of celery. Not what you want to trust your life to.
I keep a tin of bolts I use in my jigs for welding suspension parts etc. I round the hex heads off with the grinder, so I can just tighten them enough
in the jigs, but no one can use them for any thing structural.
With regard to the welded threaded bushes, cut the thread initially with the first tap, weld the tube, then finish with the second and/or third taps.
Cheers, Rorty.

Whilst we're on the subject of tapping, is the tap twisted in or hammered of a bit of both? and does one tap do all the thread or is it stages?

Had to tap holes out so bolts went in smoothly after chassis had been powder coated.
Took a bolt to local nut and bolt supplier and when i asked for a tap to clean out seat belt mounting bolts he told me they where 7/16 UNF. Got tap
and clean out holes, just takeing off powder coating no metal.
Bolts now screw in all way by hand.
