absmiami Posted May 23 Author Posted May 23 So ive decided to try the Pierre rivet thing …. These are .06 solder balls - just dumped a bunch if them on to this black tray and started drillin … .06 is a bit over scale - but the thought is that a coat of primer will help seal the rivets - and that i can leave a scale appearing rivet after some light sanding -
absmiami Posted May 23 Author Posted May 23 On the restored 38 - none of the rivets are exposed - but the best pix that ive found of the Clark 38 at Indy in ‘65 show exposed rivets - my theory is that Team Lotus used a minimum of paint and that the rivets were exposed after repeated polishing in the weeks before race day - Chapman did value appearance - but paint added weight - and at Indy extra weight made a big difference … the rivet decal that ive taped to the surface of the cowl is used to help me space the rivets …
absmiami Posted May 23 Author Posted May 23 Ths hardest part is drilling a shallow hole and making a shallow “divet” that the rivet is glued into - i want the top half of the solder ball above the surface of the body -
absmiami Posted May 23 Author Posted May 23 Getting bettter at this as i go - the right hand - in the picture - row of rivets is better than the left hand row - which was done first …
kensar Posted May 24 Posted May 24 I'm interested to see what the rivets look like when painted over.
absmiami Posted May 24 Author Posted May 24 Knsr - you’re concern - and mine - is the size of the “rivets” ….
absmiami Posted May 25 Author Posted May 25 Its a compromise - the .05 solder balls would have yielded a more sc accurate pattern - but would have been harder to handle and apply … think these .06 balls are set in securely - think they will stay put while the body is finished - more rivets needed for the back half of the body - think ill use the Archer rivet decals for those - they are black on the sheet - but i wont need exposed rivets in those sections …
absmiami Posted May 25 Author Posted May 25 I looked thru the parts bags in the kit three times - couldnt find the attenueter ….
absmiami Posted May 27 Author Posted May 27 The driving compartment side panels on the kit are abbreviated - stopping at the dash - so i made 2 panels from Evergreen strip to complete the monocoque forward to the pedal box …
absmiami Posted May 27 Author Posted May 27 The dash was then soldered to the monocoque and installed - had to do this before painting because …
absmiami Posted May 27 Author Posted May 27 I can now make the chassis extensions in the engine bay - the kit leaves these out because its a curbside …. Made from H shaped Evergreen strip, L shaped strip, and .015 and .020 strip - i’ll need to paint this dark gray … 1
absmiami Posted May 27 Author Posted May 27 The Mad Mike 25th scale Ford DOHC was an early 3D print kit engine made and sold about five years ago - it just fits into the 24th sc engine bay - this is a scale compromise - the 24th scale version of this engine won’t fit - you wont get the engine cover over it … measuring the mock up lets me know that I’ll have an issue w the wheelbase - which is 96 sc inches … the engine and gearbox w/out modification produces a slightly longer wheelbase - ill have to make some changes so that i can attach the gearbox to the suspension bulkhead … with the added bonus of an accurate or nearly accurate wheelbase
MarkJ Posted May 27 Posted May 27 Andrew, again, that dash looks superb and the engine is going to look superb too. You are the only builder I know that's not in a big hurry to finish. And it shows in the final photos.
absmiami Posted May 29 Author Posted May 29 Gracias MJ - but i am in a hurry to finish - i just keep forgetting which Lotus im building …. Anyway - as this kit is a curbside I had to scrounge around for a rear supension bulkhead - i had made one years ago for a Gurney Eagle - im modifying the casting to make the Lotus 38 bullhead …
absmiami Posted June 1 Author Posted June 1 I’ve had gearbox-brain this past week - this is the block / gearbox casting in the old IMC 25th sc Lotus Indy kit - not so much - - -
absmiami Posted June 1 Author Posted June 1 The gearbox on the right is the box that is included in the printed Mad Mike Ford DOHC kit - its a Hewland - teams like Lola - in the T90 - did use the Hewland in ‘67 and ‘68 at Indy - BUT - team Lotus - in ‘64 and 65 - used ZF gearboxes - the same ones found in the GT40s - the box on the left is correct for the Lotus 38 - its a ZF - and was included in the Mad Mike Ford GT40 engine kits -
absmiami Posted June 1 Author Posted June 1 Here’s a shot of the GT 40 ZF box - confused yet ? - Randy D can straighten us all out …
absmiami Posted June 1 Author Posted June 1 The printed Mad Mike ZF box is super - but really hard to get - and it is buried in the tail of the Lotus 38 - won’t be visible - can’t make the tail removable - so my Plan C is to use a resin casting of the ZF created by LeMans Miniatures in their great 24th scale GT40 Kit -
absmiami Posted June 1 Author Posted June 1 Have to remove the flexible rubber donut joints used in the GT40 - but these will find a home on the Lotus 25 - and just make those left and right odd shaped side plates …
absmiami Posted June 1 Author Posted June 1 So after all of that excitement (it doesn’t take much to excite me) I’ve got the correct gear box and with a little filing - I’ve recovered the correct 4 inch [96 in] wheelbase … now back to the engine mounts ….
