What materials? I suppose it needs a surface that wont reflect mid and
high frequences.

best materials are plastics such as polyethylene but you could also try
wood, the disc should not be too thin

Yes. I used lamb's wool on mine but I really have no idea
how good that is. I would suspect not very from my
disappointment in the recordings I made with it and
Earthworks TC30K's.

The MBHO pre-made one (ain't I lazy?) is made out of a thick PVC, a good
quarter inch or so. The material glued to it appears to be simply foam.

I use lambskin, wool side out on mine.

I use lamb skin velcroed to a 12" 5 ply plywood disc, with suitable
threaded studs to take the microphone clamps.

I've used it with AKG 480B omnis and Schoeps omnis with excellent results.

Bob's and my mileage obviously vary.

Yeah, I seem to be about the only person I've heard report
on a Jecklin that was not happy with it. The center of mine
was two LP's sandwiching a 3/8" cork core glued between.
The mics were a matched pair with calibration curves. I
mounted the mics themselves on a dual Sabra bracket and
placed the disk between them rather than mounting them to
the disk. I've still got it, so someday I need to revisit
the thing and see if I can figure out what was (or wasn't)
wrong.

Mine is almost free: A piece of masonite with two circular sections of high
density carpet padding. A spring mic clip on the bottom clamps onto the
mic stand around a stereo mic mount.

It isn't durable, but it makes a nice recording.

Did you place the mics at the center?

Yeah, I had little tassles that came out from the LP center
hole to get them at the center and at the correct distance.
Hmmm, I'll bet you are going to tell me that that's the
wrong thing to do. :-)

I don't know this for sure. But I would offset the mic position from
center to around 3:5 on the diameter, and btw. also use an elipsoid with
that width to length ratio. Otoh a good Jecklin setup that I have heard
was just a piece of rectangular plywood with carpet tiles on the sides.

From memory it was something like 6 to 8 inches long and some 3 to 4
inches high. Basically I think your 12" setup is too much larger than an
average head to sound right - not that I understand why it should be
"head sized", but so appears to be the case.

A Jecklin setup to my knowledge, and no - I haven't ever tried one, nor
do I plan to so do, is likely to always give a passable result, and thus
can be a good choice for "no sound check" location recordings.

Kind regards

A Jecklin is not suitable for a "no sound check" situation'

Placement is a lot more critical than ORTF and small variations can produce big
balance differences.

I find that placing the capsules at the center of the disc is a big no no and I
place them further toward the front. I do use the strings to get consistancy
on spacing.

My current disc is of the dimensions given in the original OSS recording system
by Jurg Jecklin 300 mm. My origina slightly larger 12" discalso worked well but
the additional size wasn't necessary.

My disc is plywood, covered with foam and felt.
