Easily done, Peter. I have now to try and make the front wheels look like A7s and the rears like Nash. 36 spoke v. 48 respectively. Mechanicals to do first.
Cheers, Martin

Added the front axle. It has the attachment points for the springs on top. These are turned from brass, shaped and then soldered to the axle.
The spring ends are then filed so the fit is good and the springs soldered into the attachments. Then the shock absorber legs are cut as a pair, filed up and soldered to both frame sides and axle attachments.
Finally the Austin 7 hubs/brakes have their brake levers attached, and then the drums(turned brass) are soldered to the axle.
Note the very tiny pulleys on the motor shafts and the very skinny drive belts.
Cheers, Martin

Very interesting Martin, great progress, I'm looking forward to seeing the complete drive train. Chris Not to steal your thread, but I will, this car will be on my building board in the spring. The yanks are known for doing things in a big way. This is pretty big: The Broadmoor Pikes Peak International Hill Climb is the second oldest motor sports race in America and a long-standing tradition in Colorado Springs and the Pikes Peak Region. First competed in 1916 and this year marks the 100th Anniversary & 94th Running of the “Race to the Clouds.” The race is run on a 12.42 mile course with 156 turns that begins at 9,390 feet and finishes at the 14,115 foot summit of America’s Mountain; Pikes Peak! As the drivers climb toward the summit, the thin air slows reflexes and saps muscle strength. The thin air also robs engines of 30% of their power at the summit. Competitors and vehicles must be in top shape simply to finish…let alone win! And this is Louis Unser in 1948, in a Maserati 8CTF 3031/Offenhauser, He also held the record in 1946 and 47, with the original Maserati motor, this is also the car that won indy twice. O.K. now back to our originally televised program: Martin's Bloody Mary.

Hey, it's your forum, mate! Do what you want. And we're both talking hillclimbs, albeit very different ones. Is that the Maser I did for TRRC ages ago? Damned if I can recall now! Cheers, Martin

Cheers, Martin No sir, that car has only been done by Mac Pinches, and Ostorero Slot Cars. Of the two the Mac pinches body is by far the best, Mr John warren has just re-released a slightly more refined version of Mac's body, it's of the European version, unlike the Ostorero effort which was of the 8CTF after they were sold to American Gangsters, for running at Indianapolis.

Martin, I think the TRRC Maserati was a 6CM. The one on the Pikes Peak road which is now paved (sealed) is an 8CTF.
I do like the chassis progress and want to see more.

I really can't remember now. I did 5 new masters for TRRC and I think only one was used before Dave Capelen bought it all. You should see that Delage Labourdette Klearvue!
Cars with numbers always confuse me!
John, I'm busy with Mel's new Capri pattern currently. Yeah, only a month away from a heart attack and I'm back at the bench!
So, little progress for a while, on BM.
Martin

Right, as the weather is quite nice I fancied a spell over the shed, lathing, as I call it. So I made the hubs and rims for Bloody Mary's front wheels which I want to make see through. The idea being I'll do them with thin Perspex centres mounting the turned brass and ally hubs and rims respectively. I also took the opportunity to make the bearing for the central lay-shaft in the transmission set-up. This will be soldered into a plate which will be shaped to fit the side frame of the car on the right. On the left, I will use a superb little 1.5mm ballrace that I got from Nigel Lawton. The solid wheel is the prototype of RS Slotracing's new 19" product, waiting for its photo-etched spokes. A standard O-Ring is seen in use as a skinny tyre. Cheers, Martin

Well, other peoples' wishes and the Rainy Day Tin have made calls upon my time and efforts, but idly watching Youtubes of Shelsley Walsh have got me going on the Bloody Mary model again, so here's progress, after having to make new side panels from K&S Metal Centre Aluminium. It's so much more malleable than litho plate and only slightly thicker. Litho plate is a bit crisp for hammering, but ideal for folding and rivet impressing, so I used some for the dashboard and the flat area behind the "seat". But all else is K&S, including the bonnet and the grille surround. Can't call it a radiator surround as there ain't no radiator, of course, but then there never was behind the GN original. If I won the lottery, I'd buy a GN. Wonderful simplicity, once you grasp how a chain gearbox works. Yesterday I made new side panels, reshaped the bonnet(though my unhappiness with it might yet result in a new one with steering bulge integral) and fitted the layshaft. That runs in a plain bearing on the right and a 1.5mm diameter ballrace on the left where the belts all pull at different directions. This addition showed up the fact that the rear motor needs moving across the chassis to allow the tiny belts to run in straight lines without hitting the body sides. As it is it is unavoidable to have a hole for the front motor's drive pulley, but I'll cover that with a bulge which I'll glue over it later. This I am hoping to do today. The final problem is whether there is a sufficiently long belt available from the layshaft to back axle run. A phone call to Nigel Lawton, who supplies what I have, tomorrow, should sort that out. Anyway, here's the progress as of last evening. The front wheels are RS 19"s with the middle turned away and brass hubs made, to which old test etches in brass of the 36 spoke wheels are glued. It makes for a wonderfully see through wheel which is just about strong enough for the fronts as they don't really touch the road much. O-Rings are the suitable tyres. The rears are standard RS 19"s awaiting a set of 48 spoke etches as the rear wheels on this car were GN/ Frazer-Nash. A suitable drive pulley will be made for the back axle when I find out out about belt availability. Cheers, Martin

Damn!, but a chap should read his previous posts after a long time before chuntering away. I DID use malleable ally for the grille surround, not K&S. BTW, I remade the side panels as I wasn't happy with the size and position of them relevant to the frame. Much better now, but still a pain to attach. Method not yet decided upon.
It seems amazing that I have had not only a heart attack, but in June last year a thing called a TIA, a kind of mini stroke, but was looked after like a King by the NHS and have only a tingly left leg as a leftover. Like London busses, I never saw the inside of a doctor's surgery for over 40 years and then Bang, 2 come at once, almost. I am convinced having the bench to look forward to each day, albeit for just my own stuff as and when I want is a major factor in recovery.
Cheers, Martin
