Any machinist here want to make me a record weight?

Im looking for a weight for use on a turntable. The theory is you weight the record to the platter, and you get more profound and less muddy bass as well as a crisp high end.

There are tons of them available online, lowest price ive seen is 25 bucks, and they range to 100+.

Anyone want to cut and drill be one from scrap in their shop? Its basically a 4 inch cylinder with a 1/4 inch wide hole drilled in the middle 3/4th of an inch deep. Looking for something that weights around 1.5 pounds or more. For use on a direct drive turntable.

Diy plans for a lighter and smaller Aluminum weight for belt drive tables can be seen here. http://www.soundfountain.com/amb/puck.html

Im interested in one or the other or both. Not particular with how it looks. I dont expect anything fancy.

How about a "hybrid" weight that will work for both direct-drive and belt-drive turntables? 

The weight block on top can be changed out from Steel to Aluminum, making the total weight 1.5lbs or .83 lbs respectively.  The Aluminum design you reference weighs roughly .77 lbs. according to the author.

Finish would be satin on the base and mirror polish on the weight block(s).

Quick concept sketch:



A "stabilizer" bushing per referenced design for use with 75's could also be incorporated at additional cost.

Every zero you add to the tolerance adds a zero to the price.

If the product "fails" will the product liability insurance pay for the "failure" until it turns 18?

I can only assume that it needs to be round and weighted evenly..

GeeP:

Thats a cool design too! Im soon to have my direct drive tables in one room and a belt drive table in the other. I would be happy either way, hybrid or one of each. I really only play 12 inch lp's, so i dont need the large hole 45 adapter. What would it cost to crank that out?

yep, that's the one geep !

i'm going to have to get some pictures of the eccentric doo hickey i've been whittling on for 2 months now. it usually has three guys (or more) standing there scratching their heads. we do a bunch of crusher re-tooling. the eccentric is in this diagram:


not a very good diagram at that. have to snap a couple next week.
only been in this shop 6 months. so far the crusher bowl, eccentric, and main shaft have been re-worked by me. if/when it all goes together, i'll get some shots of that too. interesting bunch of crap involved, just to crush big rocks into smaller rocks !

sorry for the thread jack, i'm assuming you already pm'd each other and stuff about the record weight :)

Looks like fun Ohgood.  I'll bet it arrived in pretty sorry shape.  They probably ran it until the 5,000HP motor wouldn't turn the unloaded crusher, or something blew apart, right?  Those are always great repair jobs.   :D

Eeeeew!  A Haas!  *barf smiley here*

Hass machines are like Windoze boxes.  Easy to use and not particularly inexpensive, but short on perfomance, crash a lot and are generally an inferior product.  But they sponsor NASCAR! :bs:

Really? We have several Haas machines (mostly lathes) and you couldn't prove those statements based on our experience. They've cranked out hundreds of thousands of parts over the last 3+ years with barely an issue. In fact, we would never have considered buying CNC equipment if our suppliers fancy high dollar machine wouldn't have failed and required weeks to repair. The relatively small investment has worked out quite well in our case.

Ha GeeP I have that same scale...actually I have eight of them, two 12", and the ever elusive 20" all in the 604R model.  I love those things!

I'd offer to cut you your weight, Respite, but it's likely to be another two months before I can get on a lathe.
