	If only it was that simple ..... Mounting method has been decided I just need to get the cut angles drawn Directly above the shock is a hole between two 1" members which is where the original shock mount bracket was with 17.5" coilovers - these are now 15" coilovers The 1" steel chassis tubes directly above the shock position have sleeved mounting holes for the roll cage and any steel in that location means difficulty with mounting the cage feet fasteners The coilover mount needs to be strong enough to transmit the necessary forces into the chassis whilst avoiding all the other mounts, linkages and ARB location points that are not shown and still provide clear access for the diff to drop through.

	Bit more on the G27 End of Day we threw some Gemini bodywork we had laying about over the G27 chassis They are all quite similar Still did not complete the rear chassis suspension mount but have the plan all sorted and it should work out quite satisfactorily. To give me a bit of "fine tuning" flexibility I am going to replicate the type of suspension bracket that I have on the Strato's You can move the mounting points around by a degrees that allow raising and lowering the ride height as well and the angle of the shock and therefor by lesser degrees the actual spring rate. Being on a vertical on the Strat they just adjust the ride height.

	Still looking in and admiring your work! On the Gemini bodywork is that a later model Spridget windscreen and surround? I seem to remember seeing an early Sprite 9 stud screen on one of your early pictures on this thread?

	I'm sorry about this and others can say what they like but I still think that you are setting the chassis up for a failure in the future only having those two mountings, when the suspension is under compression it will use the top mount as a pivot point and over time it will rip through the bottom hole and pivot about the top hole and fail. It needs a third mounting at the top say 150 mm above the current top mount and when the plates are re made it should have a 15mm lip folded into the longest side so it cannot distort under compression. I know you know what you’re doing Darkspeed but in this case it will fail as there is no triangulation in the mountings just a shearing force.

	Not a problem Pete, if I ever get it finished and it fails, and if this board is still going, I will post it on here how you told me so. It's a light car and remember it's a mount for a coilover a device specifically designed to manage forces being fed into the chassis. The static force on that upper mount bolt is around 1800N - An M10 8.8 shank in single shear is rated 51000N - the one M10 is clamping a 15mm tube in that bracket FT double shear. Full bump compression is 1800+3750 = 5500N. Keep in mind that the bracket assembly is connected to the coilover that is connected on its lower end to a bracket on a 32mm diameter 2mm wall tube wishbone! I know where my money would be on what is going to fail in that system. Jun 5, 2021 9:51:39 GMT flyingphil said: Still looking in and admiring your work!

Cheers Phil - Yep they all use Spridget screens - I was looking at early screen at a car show as they are a more delicate frame than the heavier later ones. Once you remove a few bolts and flanges here and there drill a few holes they look okay. Would have been on the Gemini thread.

	Managed a bit of progress on The 27 today. Tubes drilled for sleeves. The sleeves, left over from G15 chassis work have since been reduced in width and at some point tomorrow I will get them welded in. Also need to get a couple of pairs of brackets drawn up and made.

	Started early before things go oppressively hot and two welds are as far as I got before the battery in the mask gave up the ghost and started flashing full arc at me. Also looks like I only have about 20 bar left of the 300 I started with so about 400 litres or 45 mins of welding time - Time for some alloy welding practice to end the bottle after I finish this little job.

	Been messing about on another G27. Could go into a long diatribe about Ackermann annoying squealing tyres and an unhappy driver and the whys and wherefores but have a list of works instead. Remove old rack mounts and weld in new ones Strip rack and replace:- Rack - Track rods (Longer) - Pinion - Track rod cups - Rod ends - Lock stops. Mixtures of Spitfire, GT6, Dolomite and V8-G27 parts! Purchase solid rack mounts. Drill new mount holes. Wind from lock to look and it looks like we have symmetrical steering angles left and right - previously found to have an inherent asymmetry Once painted and geo set I will report back if driver is happier.

	Mar 4, 2018 21:06:49 GMT Darkspeed said: I am not convinced that the chassis could be called a space frame - a frame with lots of space, now that I will agree on but a space frame - No its a platform/perimeter/ladder frame - The only saving grace is thats far better than the G33 chassis which is much the same just wider and longer so even more wibbly. Those that know me we confirm I have a thing for triangles, tubes and things being lighter than they were originally. So, with that in mind the first thing to do was to sort out the ugly on this chassis. You may note the chassis above actually has two sets of engine mounts! Yep, the chassis was just a stock standard Pinto IRS chassis with some mounts for the Rover welded on. However as they had raided the G33 parts bin all of the wishbones are bespoke. Although, as we have already discovered, that is not necessarily a good thing. I am really not a great fan of sheet metal reinforcing and in the case of the G27 it all had to go - Sheet metal does a far better job when it's rolled up into tubes and used to triangulate. Lets have a few snaps of the dirty bits of the chassis and then a few more of me feeding my tube fetish. It took many weeks to chop all the nasty off the chassis. But from this basic chassis we had the foundation on which to build something with the ability to resist the twist. This was also going to get in the way of the plans so it was out with the slitting disc. So we could get a clear view of where tubes could go. Another great thread and good to see the Wem Ginetta chassis improvements applied to the G27. I find one project at a time taxing so I'm totally in awe of your energy in keeping all yours moving forward together.

Cheers John, I am not making the sort of progress I would like to be at the moment for a many different reasons. I am having a lot of one step forward 40 steps back right now. Just have to keep plodding on.

Pleased to report that with the rack rebuilt, centred in the chassis and located to minimise bump steer, that we have success. What looked right when we had finished , works right in operation. No squealing, far better turn it and no nervousness in a straight line. He now just needs to drive it more.
