Race chassis

what is the best material to construct these frames out of?

I mean obtainable stuff that the normal man could work with.

16swg seam welded mild steel tube, as in exhaust tube. Any exhaust shop will sell you pieces by the meter, most of 'em will let you rummage through their scrap bin for bits of bends etc. You might have to hunt around for some of the smaller diameter bits, but it's cheap enough.

You can gas weld it, TIG weld it, MIG weld it, (if you must) or braize it, choose one method and learn how.

That's all. The only real "trick" is making the joints fit perfectly and clamping it together BEFORE you pick up the welder.

looks like its been all done before we should give up why we are ahead

NOoo..

You'll just have to dig out that old centre hub steering beast and mount it into something new...

I was going to check but seeing as you brought it up, but as most of us (Well i don't have much patience) i saw a notcher in a tool mag the other day Topmaq i think.

Never owned one, I got by with a half round file, a 4" disc grinder and a die grinder. But then I don't do a whole lot of tube work.

Stil, any excuse to buy tools...

I have not a lot of patience.
but yes a chainsaw files are real good for detail work also awesome for slotting out holes on manifolds etc.

Come to think of it as its diy......... Chainsaws Nah... no Lux saws love em i wish i had one.

But cheap Drill press and tapered grinding bits also work. Or just the drill and tappered grinding bit.

Also Bimetal holes saw bits are real useful and last surprising well if lubed well.
Even the cheap Warehouse style bargain bin ones will do a few cuts if lubed.

I do - and you've got the right tools. Notchers are a waste of money unless you're using very heavy wall tube. You become an artist with a disc grinder with practise.

The only part I do differently is swingarm legs - I use a holesaw in a jig to profile the inner ends and ensure they're the same length.

I buy my tube from specialty steels in ChCh who took over Southwards a few years ago. Many diameters and gauges available and pretty cheap too. Using offcuts you often find you just don't have the right size....

MIG weld it, (if you must)

I use a MIG because I have a desk job and haven't learn to use other methods.. The old man gives me shit and whenever there is a real critical join he offers to do it for me with "Something better than that hot-glue gun".

[Pumba]

Plywood, cover sheets are cheap as Bro

Sweet. Neighbors are building next for a there are scraps of roofing ply just lying around, odd bit of 2x4 as well

[F5 Dave]

. . . Any exhaust shop will sell you pieces by the meter, . . .

So look for their Meter & buy the steel under it.

[Kickaha]

odd bit of 2x4 as well

You can use that for the swingarm

[husaberg]

Although done by Terry Prince.
Sorry the quality is a bit poor. But it is of higher quality than Kicka's last joke

This style of spine frame is normally used to house sizable lumps such as fours and Vincents harleys etc.
