Bengalensis Posted August 22 Author Share Posted August 22 No real modelling work done today. First I had various paid work tasks needing attention and discussions, then I continued behind behind the large cad screen doing things more interesting, Like a set of wheels in true scale dimensions. Using the Minilite file I got from Brus I reworked some details and measurements to get a front and rear wheel. Then I created a set of front and rear 888’s. I’m afraid that these might be a tad too large for the model, even if the measurements are correct. But I’ll print a set and see what happens first. While I was at it I did a hand brake, hinges for the rear hatch (not sure if it really qualifies for a boot lid…) and altered a fire extinguisher from my cad collection to fit (this car is small inside…). The exhaust part in the kit isn’t bad, but it’s just a plain pipe and a rather long silencer, and all a bit thin. I like the set ups with the collector coming through on the outside, so I created a new piece. It might need more tweaks after the first print. To finish it all(?) off I made a new seat cushion and back rest, as two separate parts. These are so simple and “block like” so I can easier get away with my engineering orientated cad set ups. Some day I will have to look deeper into creating more traditional seats, but I don’t forward to that... Then I was too drained to prepare the files for printing and start the printer over night, which would have been ideal. I resorted to the wine bottle (must keep the stock of foil for seat belts up) and hopefully something to eat. I’ll start the printer tomorrow morning. 8 1 Link to comment Share on other sites More sharing options...

It may very well be that I have to make some "scale adjustments" on the wheels to get the whole unit working together, which is what must dictate things in the end. 1 Link to comment Share on other sites More sharing options...
Bengalensis Posted August 23 Author Share Posted August 23 So the 3D-printer has done its work. The success is limited, I tried some different orientation of parts that wasn’t terribly successful, and somehow I managed to mirror the front tyre in the slicer program. What a joke. But the wheels are good for judgement. I should probably open up both the front and rear wheel arches a little bit more, but it will probably not be enough. Also I have a bit too much ground clearance here I think. The printer is now working on a new set of wheels, and a second set of wheels reduced to 1/25 scale. And yes, tyre orientation will be observed (I hope) when it all becomes serious. The seats turned out OK, I think these can be used. The extinguisher will work as well. Compared to my 1/1 Lotus the passenger in this car is probably a little better off... My friend Brusefält suggested these mirrors on stalks for a current road/race prepared G4. I gave them a print, the idea is not bad, but I will dwell on that. The exhaust is promising but needed some added lengths and a tweak. The printer is working again... There is fuel cap included in the kit, but it’s quite crude. I will use the one I just made for the Cooper 500. The hinges should be fine. I cleaned up the rear light parts and made a license plate base. One of the orange lights is a bit short on resin, but there are two identical white lights included that I have no need for, so I will paint those in transparent orange as a replacement. 7 1 Link to comment Share on other sites More sharing options...

keefr22 Posted August 24 Share Posted August 24 More very nice 3D print parts Jörgen, even allowing for the tyre 'problem' the wheels look superb! And, again totally unscientifically, to my eyes they look a better fit to the car than the other 13's you tried. Maybe one thing is the tyre sidewalls are a little tall - even the historic type tyres fitted to the little beauty in Sabrejets pics look to have less sidewall? And I'm not sure of regulations anywhere else, but I think for historic racing in the UK you have to run treaded tyres like that car, which will generally be narrower than the Toyos. Just mentioning that as you said you were building it as a road/race car. Of course the owner might have a set of Toyos for the road...!! Repeating myself though, I really like those Miniltes....!!

Keith Thanks a lot Keith! I am indeed quite happy with how the Minilites turned out. The 888's I have drawn here are 185/60x13 front and 205/60x13 rear and they are spot on in all dimensions in 1/24, double checked against my own tyres. I suspect that is a bit on the wide side for most G4's, and the profile of course follow the width. I have studied photos of a G4 for sale that's running on 888's, but it's got 185/60 all around. I might be trying to press in more tyre than needed here, maybe should go down to 165 and 185... And yes, most R-tyres like the 888's always looks a little meatier than more ordinary road tyres, so going away from the 888's would change the look a little. I have also just done the visual test with 1/25 wheels... 2 Link to comment Share on other sites More sharing options...
keefr22 Posted August 24 Share Posted August 24 Apologies Jörgen, I wasn't for a second doubting your measurements of the tyre sizes, what I was clumsily trying to say was that those particular tyre sidewalls looked visually a bit tall on the model.

stevehnz Posted August 24 Share Posted August 24 Late to the party as usual but I'm seeing a lot of things to like here so I'll hang around if I may. I've long had a soft spot for a G4, they're such a pretty wee motor & for my part, Minilites & a hard top set them off beautifully.

Keith No problem at all Keith, I quite agree, and trying to understand why it is so. You see I remembered wrong about that G4 on 888's for sale mentioned above, it actually runs precisely on these two dimensions, 185/60 and 205/60, but doesn't really look like this. Now I realise the the slightly widened arches front and rear, nothing really dramatic, fitted to it makes a lot of difference. But I don't think I want to go down that route. 55 minutes ago, Sabrejet said: Well there's a thing. I'm really not sure. It had a Lotus twin cam engine and looked original. But it's a race car... The few G4R's built by the factory had the Lotus twin cam, and the independent rear suspension with inboard disc brakes. Looks like one indeed with that rear brake ducting, but I suppose several more have been built in more resent years. 22 minutes ago, stevehnz said: Late to the party as usual but I'm seeing a lot of things to like here so I'll hang around if I may.

The more I look at it now with all wheel testing, the more right the hardtop gets. 3 Link to comment Share on other sites More sharing options...
Bengalensis Posted August 24 Author Share Posted August 24 The second version of the exhaust, I think I will go with this. Then a test with a set of 1/25 scale wheels. That is about 12,3-12,4” in 1/24. The ground clearance is now fixed as best possible according to the FIA homologation file, whatever that is worth on a model like this... First I thought that this could be the way to go, but the more I looked the more these wheels didn’t look quite right. I know there are people who find my testing and inner debating back and forth like this doubtful, but there is no way I can convey into the thread how much input it gives me. I often do it. And it’s so nice doing it on the rotating stone plate. I then went back to the true 1/24 scale 13” but here with the smaller 185/60 front wheels all around. I like this better. The wheel arches both front and back needs a tiny bit more opening up, then this is probably not far away, if one is happy with the same dimension front and back. I may try doing a 165 front tyre. I think I will have to make the true 13” wheels work. 6 Link to comment Share on other sites More sharing options...

triumphfan Posted August 24 Share Posted August 24 What a lovely subject. Beautiful little Ginetta!! Looking good Jorgen. I totally get the lengthy process of wheel & tyre choice. Something I spend a lot of time on as well, stance is also important for the overall 'look' of a car. I'm sure you will get a typically gorgeous result from this old kit, can't wait to see it 👍 Atb, Steve. 1 Link to comment Share on other sites More sharing options...

Keith Spending time on wheels/tyres/stance/alignment always pays off! Lucky find! Having the rotating board on the bench is far better than not at all, but it's worth quite a lot to get it up. This is not ideal, but it will do until I get around to the reorganisation... 1 hour ago, triumphfan said: What a lovely subject. Beautiful little Ginetta!! Looking good Jorgen.

I kind of suspected you would like this 😎 It's been in the stash for far too long... Indeed, the wheels/tyres/stance/alignment thing is a bit of make or break point. If that goes wrong it's IMO very difficult to compensate for even if the rest of the build is top level. 58 minutes ago, Sabrejet said: Certainly was IRS: Lovely!

Bengalensis Posted August 24 Author Share Posted August 24 Well, creating a 165/60x13 888 was by far the easiest and quickest 3D-cad-print work I’ve ever done. Toyo do not have that dimension, 185/60x13 is the smallest. So I couldn’t make it. I went back to the work bench and did the adjustments to the wheel arches I wanted to do. Then I loaded the tyres with a little weight. And here is where I am now, back on true 13” and 185/60 + 205/60. Another interesting thing is that now the wheel base has increased closer to 1/24 scale, still a little shy, but at least now on the right side of 1/24,5... 8 Link to comment Share on other sites More sharing options...
klubman01 Posted August 24 Share Posted August 24 Good progress on the G4. The 3D printed parts add the lovely little enhancements I've come to associate with your work. Regarding the various wheel/tyre combos, you will have several sets of perfectly useable surplus items for future projects whatever your final choice.

Bengalensis Posted August 24 Author Share Posted August 24 Most interior parts prepared. Still needs a pull handle for the extinguisher. Test fitting the head lights. These will do, especially with black tape across. Then there is this issue with the mirrors; which to use, where to fit them... 6 1 Link to comment Share on other sites More sharing options...
