Hello everyone.
As part of my DIY turntable, I found plans for a DIY record clamp, and made one.
Took about 45 minutes and looks OK. I think I may grit blast the large OD to give it some contrast and hide the marks on the bar...
it will be a gift to my soon to be Father-in-Law for his Rega Planar 3!😀

Yes, it looks rather tidy 😉 Nicely done that man.
I'd probably go the lazy route & cast one out of lead & then paint it 😀 That or stick a few magnets underneath an alloy platter & use a ceramic ring magnet on top. The mind boggles...
Must be nice to have a lathe, i wish i had a complete metal/woodworking shop 🙂
Thanks!
I've got access to all sorts of machines and materials...
Could have made it from OFC or Yellow Brass (maybe even a tungsten insert in top??) but it gets too heavy... I choose to use aluminum (or aluminium to you 😉) to keep the weight reasonable.
Maybe the next one will be aluminum with an OFC band for color contrast... Or wood/copper... Plenty of ideas!

I certainly could...
We send out stuff for anodize all the time... Black or blue regular, or gold hard anodize...😀

If its magnetic, it will pull the cart towards itself as you near the end of the record....
non-magnetic, no probs though!

Well, I could be wrong, but I think stainless steel is non-magnetic, or at least very weakly magnetic.

You could be wrong Fran, but it would be expensive, and a lot of trouble to make you so.
Yes, stainless steel, is generally not ferromagnetic. You can get alloys that are magnetic, but at a price.

Stainless is usually non-magnetic, but unfortunately not always...
manganese alloyed , aka " acid proof" is usually better.
I've actually used it as rebar in a small earth-magnetic observatory building, with no problems....

I've been thinking about ebony/cocobolo and copper as the next version...
I think they look nice together!

Well, delivered the weight to my (future) Father-In-Law and he really liked it.😀
Over the course of the evening, he pulled the platen off his table and showed me it was a glass one! I did not realize that, as he always has the felt pad on top.
All I know is that his old Planar 3 sounds quite good! I hope my home-made table will be as nice sounding!😕

diy record clamp.
thats looks awesome . im a cabinet maker by trade and actually made three clamps using scraps of corian . 1/2 thick material. layered it 4 times using black white gray ,granite colors and filled them with 6 ounce flattened sinkers. beautiful weights about 1.25 pounds.

Hi,
Nicely engineered job.
Record clamps can work very well when properly designed (not saying this one isn't) but most tend to couple the noise present at the spindle to the record.
Noise that will be picked up, time delayed by the stylus and will end up amplified at the speaker end.
Just as with electronics, mechanical engineering is a matter of taking care of impedances.
I have no intend to rain on the party, just to make people aware of possible pittfalls. 🙂
Ciao, 😉
