Do you mean an ordinary point at the entrance to a balloon/reverse loop with 4 foot radius on the curve, or a curved point where the tightest radii is 4 feet?

A curved point similar to this ho scale example

Trainline 45 does a curved point with 1200/2400mm radius tracks, in left and right hand versions.

Piko also do a curved point.

doesnt exist for R1. your smallest option is the piko curved switch which is outer R3 and inner R2 (LGB Radius), so 8ft and 5ft.

LGB R1 is ~2' foot radius (actually 600mm) and not what the OP was asking for!

Ah yes, quite right, missed that. The question is are they looking for 4ft radius (8ft diameter) for the inner or outer curve? The Piko curved switch is R2/R3. Trainline make some that are R3/R5.
Ah thanks for that, I have a TL one that is a bit of a pain in the space, clearly a Piko one would suit me better.

As so often I am confused. I've seen it stated elsewhere that Piko R3 = LGB R2 as stated by Diesel2000 above. However the LGB geometry chart states that LGB r" is 1560mm diameter = 780 mm radius. Piko's chart says their R3 is 921mm radius.
Could someone with a more geometrical brain than mine clarify the position?
Reason for asking is that I need a point to branch off a LGB R2 curve (so inner radius LGB R2) and have been hesitating over the cost of the Bertram Heyn solution at over EUR 200 ready made. I don't have the skills to assemble the kit.

Put simply, Piko R3 will fit inside LGB R3 as double track.
Or outside LGB R2 as double track. I've posted a comparison somewhere on the forum with a photo of R1/2 with Piko R3.
If you can find a Train-Line R2 point this would be close enough for your purposes Ade....

The "R" numbers in themselves are pretty meaningless, as each manufacturer has a different series of radii. In G scale all seem to use LGB R1 as their own R1... but after that all bets are off.
For reference - LGB R1 (600mm), LGB R2 (780mm), LGB R3 (1195mm), LGB 5 (2320mm).
