Yes, you should've Never mind fingers, he's got plenty more...

The trick is to have tha camera ready before you start (maybe I should follow my own advice )

Well, I got lots done today; I tacked the front bumper to the axle

...but seriously folks, I did a bit more than that...

About a week ago, my compressor stopped stopping... er, it would no longer cut out once pressurised. A quick call to the place I bought it revealed it had blown head gaskets which arrived in the mail a few days later. So, today was all about changing them & getting the compressor running properly.

After I'd done that, I started out making the extensions for the frame; now where will I find a piece of tube/pipe/round bar with an OD of 22mm? Answer: NOWHERE! Guess I'll have to make something...

As I had some excess 25mm tube, I decided to use that, slice it down the seam repeatedly until it fit inside another piece of tube then shrink that down to fit inside the frame tube.

After slicing & squeezing for an hour, I had my two extensions with internal plugs ready to weld into place. A few measurements &... wait, I don't need them, the frame is long enough without them.

I suppose it wasn't a complete waste of time; now I have a pair of 1" joining plugs if I should ever need them...

Don't you think you should have measured the frame before making the plugs

But seriously, nice work on the plugs. They would have worked great

well, I sort of did: When I first started designing the frame, I took all of the usual body measurements & the measurements of the original frame & found a workable medium. So, once I had the seat frame in position, I sat in the frame & set a "comfortable position". Turns out that the driver isn't meant to be in a comfortable position

lol, possibly. I mean, I'm not big (5'9" & 170lb) but, it seems it's even a bit small for me... I'm sure I'll manage

Hey, why not? I've been wanting one for years, more so over the last year. Now I have one, why wouldn't I show it off

J/K I would too! I need a lathe but I needed a mill worse when I bought it. I got no room for both. But I can do some pretty impressive turning with the rotary table and and endmill. I've even made o-ring and snap ring grooves with a wooduff key cutter as well as internal tapers with a dovetail cutter.

I don't use it as much as I could. It's hard to run a machine tool all night and then come home and run one all day....

lookin good. my orange krate is 5:1 ratio(12t clutch 60 sproket) with an eleven inch tire. my only frame change to suggest is a narrow steering hoop. if you expect anyone small to ride it short legs dont clear the wide hoop easily.

There are some bench lathes that have milling attachments; that's the next thing I'll be looking into.

I've learned some pretty neat tricks over the years too; it's amazing how you can improvise when you have to

Well, I got quite a bit done over the last few days, including spending 20 minutes typing this out, only to hit the wrong button & lose it all

First up was setting the steering column in position. Using a piece of 30x5mm flat bar, I made a tab to hold the bottoom end of the column to the front of the frame & set the angle of the column. It was at this point that I realised just how short the column was so, I set about extending it.

I found a piece of round bar that fit snugly inside the column & a piece of pipe that would work as an extention once I turned it down a bit.

Then to fit the steering wheel boss to the extension. size was almost perfect but, the boss is supposed to have a thread in one side... note: supposed to... I decided to tap what was left of the M6 thread out to M8 & use a button head allen key bolt to fasten it so, off to Express Industrial Supplies for... well, supplies. I also bought a bunch of M6 nuts, bolts & washers for the sproket & brake disc hangers (I'm gonna need 'em eventually, right), 3 for the steering wheel & two M8 x 60mm bolts for the steering column upper support (I'm getting to that...)

Back home I cut & drilled two 100mm lengths of 25 x 5mm flat bar to fit the $7 sprint kart column support I previouosly picked up at the local go kart store. Then I took the two pre bent lengths of tube, cut them to length & crushed the ends to fit the flat bar. Then I had to carefully "adjust" the top, crushed section so it was square with the bottom section. Then I cut the bottom section to length & bird mouthed the ends... on the wrong angle what a mess! Thankfully, it all worked out in the end...

Jeez, Fab- at this rate, you can do 5 MORE builds with the remaining time allotted!

Nah, not quite, this is the easy part, I still have a lot of details to sort out...

Although, if you recall, I still have at least two other ongoing builds to complete...

Man you work fast. The frame looks real professional. Good job. You should finish soon enough to get all the bugs out of it before the deadline

Maybe from a distance but, close up, it has a few flaws ATM...

That's what I'm hoping but, I didn't design any bugs

You don't need to design any, they just fabricate themselves.
