Can't get Technics Baerwald arc protractor to print to scale

Post by RobberOfBostonPlace » 31 Oct 2019 19:12

This is a problem I have with every protractor on this site. I can't seem to get them to print to scale. I have a cheap HP Deskjet 1010. My turntable is a Technics SL1210 MK2. Any help is appreciated. I really want to get my cartridges aligned.

There are two possible reasons

(1) An option is ticked somewhere telling the printer to 'fit to page' or 'scale to page'.

Make sure the printer is set to 'print to scale' in the options screen and see if it fixes the problem.

(2) The printer doesn't print to scale.

In this case the easiest thing to do is print it at work/on a friend's printer or stick it on a USB stick and get it printed at your local print shop (if you have one).

Alternatively use Conrad Hoffman's alignment template generator and use the 'printer correction factor' X or Y to suit your printer.

If I go the Conrad Hoffman route I could be there forever trying to figure out the X and Y factors.

Doesn't Technics use the Stevenson alignment? It may not be that the scale is wrong, but that when you use the Baewald alignment with Technics arms, the cartridge ends up all the way forward and cocked at an odd angle.

When you hit Print, you get a dialogue panel. Select Print to 100 %.
If that is a bit off, you can ask it to print to 100.4 %, 102%, 99.1% - whatever is going to get the correct size.

I can get the A side to 140, but the B on the Baerwald protractor only gets to 190 as opposed to 200. Are there any good resizing tools around?

That's a nasty one.
You could still use a 2-point protractor, as that is linear, not 2-dimensional.

That may be so, but if it's aligned on both points there is no problem.

I recognize that you can use most alignments with most arms as long as you get the two points right - I've done it myself often. But I was checking to make sure that the OP wasn't confusing the cocking of the cartridge in the headshell with a problem with scaling. If he assumed the cartridge ought to be straight, he will assume that there is something wrong with the scaling.

Interestingly, I can print a Rega Baerwald protractor and the 200mm and 140mm are perfect. If I use the exact same printer settings on the Technics version I do get the correct 200mm but only 139.5 for the 140mm :shock: :shock: :shock:

You might try saving the pdf as (or exporting as) a jpeg, then printing the jpeg.

OP, here's another thing you can do, forget the paper protractor, since the Technics alignment scheme for minimum tracking error requires no protractor. Just screw cartridge to headshell for a somewhat loose condition and set stylus to headshell tail distance to 52mm. Then square the cartridge to the headshell and tighten mounting screws. That' it, unless the cartridge sets tail high at Technics minimum VTA setting, which means it will require shimming for a level condition resting on record.

Why some people still using Baerwald scheme for Technics?

I don’t know why, since the Technics scheme is quick and easy for a result which is awesome.

I have couple of carts and I have to say I have some carts aligned to standard Technics 52mm and some carts to Baerwald. I'm sure there is sonicall difference between them.
