The Dremel/sanding drum combo was too slow with Jarrah, so instead I'm rounding the outside of the tyres with a 1/4" router bit. Much faster. Just gotta be careful: -

Are you having a wheely good time now Steve.
I've been side-tracked catching up on a few things, but got the outside of the tyres trimmed to their final size. I took them down to about 61mm with the router bit, then the rest of the way with a Dremel sanding drum to avoid chipping at the edges.
All are 60.0mm to 60.1mm, ready for the centres to be trimmed out to 45.0mm to fit the rims. I'll get into that tomorrow. (Correction - later today - it's almost 1am, I just noticed.)
So far so good.
Today I finished routing the inside of the tyres to just short of the final dimension ready for fine-sanding to fit the rims: -

Also fine-tuned the first tyre to fit snugly on it's rim. Doesn't look too bad: -

All good so far. (Touch wood.)
After all tyres fit well, I'll shape the side-walls to look more like tyres, then if I feel adventurous I'll have a go at adding tread.
I got the last of the steering gear glued up tonight, so the chassis is all set for the wheels when they're done.
The rods already have a coat of poly, but I still need to do the rest yet. (Should hide the glue spots.)
AAAARGH,
The memories, The Horror, The Chills, Why do you torment me Steve???
I'm going to hide under the bed till the memories fade.
Tyres all (temporarily) fitted: -

(I'm surprised I got this far without breaking any of those fragile rims.)
Onto the hubs next...
Thanks crowie.
A question for those that have built this model in the past.
I remember reading somewhere that when drilling the hole in the base plate for the steering column, it's best to drill at 30° rather than 45° recommended in the plans.
I can't remember where I read this, but can anyone shed any light?
Something that's bugged me since the beginning is the shape of the bumpers in the plans.
They call for dead flat bumpers front and rear, whereas the majority of Model A's had bumpers that were curved like this: -

Also, you can see that the original bumpers had a short rod rolled into the ends.
I've decided to duplicate both of these features in my bumpers if I can, to try to make them look a bit more realistic.
The new front bumper: -
Attachment 216713
My rear bumper will be different, made up of two shorter bumpers to accomodate the spare tyre on the rear, since I'm really building a '28 and not a '30 as the title suggests. (The plans said 1930, hence the title.)
Good morning Steve but from the time on your post you already knew that.....lol.
Are you planning to make metal a bumper?
It'd look fantastic if you are, though a lot of extra work to do it.
Take your time, maybe a bit of stainless steel if you can score some or "bright chrome" paint of mild steel would look good.
Well done.
Cheers, crowie
Great model certainly coming along now:2tsup::2tsup::2tsup::2tsup:
Morning crowie. I'm keeping long hours at the moment. No rest for the wicked.
No, I'm making the bumper out of timber, Camphor Laurel, but more in the shape of the original.
I've roughly marked it out to cut out today while I'm cutting the hubs.
I'll drill the holes in the ends first for the rods, then cut out the inside before splitting it in two for the two slats and shaping the outside. I'll use a short length of blackened bamboo toothpick for the rod.
(I dreamed bumper bars last night.)
