Universal Protractor

We have revised our famous „Universal Protractor“. Besides making handling easier we have enhanced the functionality as well as accuracy. On this Protractor you can find all three well known, major geometries aka Baerwald, Lofgren and Stevenson.

Theory

The general geometrical correlation of a tonearm based on a fixed pivot point are well known since the fundamental publications of Baerwald and Lofgren back in the first half of the 20th century. The conclusion of both papers was that such a tracking device must have an angular offset (zenith) with a defined overhang. The offset and the overhang vary with the effective length of the tonearm itself. While tracking the record the stylus matches tangential position in the groove at two points – the inner and outer Null points (linear tracking position). In the early 1960ies another mathematician has calculated a new set of parameters taking into account that on records with classical music very often crescendos occur towards the innermost grooves (Stevenson).

How to - step 1

Choose the geometry you want to use: Baerwald (B), Lofgren (L) or Stevenson (S).

Screw the gauge tower on the disc and place the Protractor on the platter. Aim with the pin in the gauge exactly over the pivot point of the tonearm. Move cartridge in the headshell so that stylus lands on the crosslines of your chosen geometry (B, L or S) at step 1 (overhang). In case you cannot reach either point on the Protractor please check your pivot-spindle distance.

Carefully tighten one screw a little bit and make sure you can still turn the cartridge in the headshell. Set antiskating to zero.

How to - step 2

Turn Protractor so that you are over area of step outer Null-point). Set angular offset (zenith) so that the printed line on the Protractor and the cantilever of your cartridge fall in line when looking from the front. In case this is done carefully tighten both screws in an alternating way and take care the cartridge doesn‘t move anymore in this process. Caution! Don‘t overdo the tightening of the screws as really tight is followed by infinitely loose forever …

Double check your setup either at step 3 (inner Null-point) where the cantilever MUST fall in line with the printed line or you can alternatively check the overhang again at step 1. Both approaches are mathematical equivalent; if two points are correct, the third is correct by default. In case the cartridge still is off, then start again from the beginning by checking the overhang first and subsequently all the following steps again.

POLYESTER?!?!
Color: Ivory, Size: 2' x 3' (Pelt), Color: Ivory, Size: 2' x 3' (Pelt)
POLYESTER?!?! So i just bought several of these. Nice and big and fluffy, looked very clean, very nice. Cats instantly were scared/curious. The back of the skin, the wool, all looked nice, and then I noticed it had a tag on it... The tag says... 100% POLYESTER! What?!?!? This is supposed to be New Zealand Sheep Skin pelt! Shouldnt be any Polyester at all. So, just before I was about to return it, i did a small burn test. I cut off a small bunch of hair and burned it. The fire tried to light but it quickly extinguished itself. And the smell... yes... the smell told me it is REAL WOOL and the fact the fire went out right away also confirms this is not oil based. THIS IS REAL, This is NOT Polyester. I guess also a lot of ppl are returning because of the tag, so these are at a HUGE DISCOUNT!!! BUY THEM UP!!! They also came in vacuum packed bags, looked nice and kept very nice. These are excellent! See my photos, the tag, the burned bunch of hair... fire went out, i tried it three times, fire kept instantly going out... smells organic like animal hair when burned, not like oil/polyester. ENJOY!!! I PAID FOR THESE, I was not given anything here!

Love this product!
Color: Linen, Size: 2' x 3' (Pelt)
This sheepskin elevated a boring leather couch to a luxurious sitting space! I purchased 2, one for each loveseat, as sometimes the leather is a little cold. The sheepskin with a small lumbar pillow and voila! A cozy place everyone gravitates to! The sheepskin is soft and cozy and everyone comments they want one! ha probably will get this as a couple of gifts (for those guests that said they wanted one too)

Perfect sheepskin rug
Color: Ivory, Size: 2'3" x 3'5" (Large Pelt)
This sheepskin rug is fabulous! I have it over my office chair and I LOVE it. It does not shed, it stays in place and fits over the seat and up the entire back of the chair with a bit remaining to hang over the edge. My cat sleeps on it every chance he gets. Great value for the price! Just looking at it brings me joy, such a beautiful sheepskin.

Dog ignores, but I like
Color: Ivory, Size: 2' x 3' (Pelt), Color: Ivory, Size: 2' x 3' (Pelt)
I bought this for my dog, who is old and has creaky joints. My dog prefers to continue resting in uncomfortable places that put my plants in peril. He does not ever recline on this dead sheep and looks at me as though I am the sheep slaughterer. Spouse asked if it came in bigger sizes. Since this is the skin of a dead sheep, it depends on live sheep girth. Anything bigger would likely have to be sewn together from multiple dead sheep. I find the girth of this sheep pelt perfectly acceptable. It is nice and thick and soft and fairly easy to vacuum. I frequently recline on it when stretched out on the floor, and am grateful it does not leave a mess or make noise like my dog, who should be grateful that his pelt is still attached to his body.

SHRINK Wrapped. NO Customer Support.
Color: Ivory, Size: 2' x 3' (Pelt)
These arrived shrink wrapped and when put down as throw rugs, are lumpy. They are a little less so after 10 minutes on air fluff in the dryer. They look nice and fit my bedroom well but I’m concerned about walking over them since I prefer a level surface that is even. Customer support does NOT exist. There appears to be a chat option but there are no responses. Reading other information, I’ve decided to try a metal comb. So now I’m waiting for that to arrive. If it wasn’t so difficult to deal with the size difference, I would have simply returned them. I may still and just purchase a return container.
