I believe that Hugo looked at the simpler Linn way of having a bit scooped out of one side of the hole, leaving two vertical "edges" to act as stable mounts, the piller held in place with one bolt as near as near midway up as possible. Linn called it an "engineers' clamp." This would give a three-point mount as near as possible and at least the pillar wouldn't be able to move.
I did look at that, since the original Jelco collar has a similar arrangement that does not work because the collar otherwise does not hold the arm pillar correctly (unlike the Linn collar for my Ittok LVII which is an object lesson in how to do things properly). In the end, a precisely machined hole was so snug a fit that anything more elaborate was unnecessary.Quote:

Hi Ninja,
I machined up my version of a mounting collar for the Jelco in mid august. it was commisioned by a guy in Fort Collins CO. But now that I am reminded, I never did get a reply from him as to how it performed.
I will email him now.
If there are many people out there who still require one of these then I will set about machining some. I use a precision hole and two 4mm securing screws at 90degrees. The collar can be made in Brass or Alluminium. The screws are actually Hex socket heads which protrude from the collar and permit tightening with the fingers first to ascertain the requred height.
The hex screws can then be clamped up using a Hex Wrench.
Thanks Mike,
I am interested if the price is about the same "level" as before.
ninja,
I have just had a reply from the guy in the US, he says that the collar works fine and that the two screws allow for secure adjustment and clamping. He did give me a couple of thing to improve.
However I got an email from Hugo yesterday saying that he was intending to restart the making of collars. There is no future in two of us doing it, so I have left it to Hugo to do what has to be done.
I do not wish to tread on Mike's toes here - his collar design is different to mine and I like to think that there's room in the market for both. That said, I have had a preliminary conversation with a potential retail partner for my collars. If that proves feasible, then it will be much easier for anyone wanting a collar to buy one whenever they wish, as opposed to waiting for me to produce a batch. My collar design is exactly the same as the last lot that I did, eg in CNC-machined aircraft grade aluminium, vapour blasted and brightened/anodised for a durable finish. This time, I can look at doing some of the collars in black anodised finish, since I know that some customers did want this before.
Thanks Mike and Shuggie, I'm still interested and I am not in a hurry, so, I can wait.
Silly question to most of you Jelco owners, but is one of the 750's a drop fit into a Rega hole (suitably modified)? I only ask as it would appear that the standard 750 as used on the Techie is similar to the Linn-length arms, although I'm not sure if the 10" version wouldn't be too long?
No, it would not just drop in - the mounting distance is totally different from either Rega or Linn arms, whether you are looking at the 9" or 10" Jelco (see the Tonearm Database over at Vinyl Engine). Also, the mounting hole is a different size compared to any Rega based arm.Quote:

Thanks!

Your Pm system does not work, until you have a certain number of posts under your belt. We like new members to take part in the forum for awhile before such facilities are activated.
Regards D S D L
Indeed... And one of those facilities is also taking advantage of the offers in our classifieds section.
I'm getting a little weary of people who join here simply to buy or sell something, and don't read the joining instructions properly when registering, which clearly indicate the necessity for posting in the Welcome area FIRST, and introducing yourself, BEFORE doing anything else.... :rolleyes:
I wonder what we have to do to get folk to acknowledge the instructions - put them in big red flashing neon lights??
Marco.
Offer them a bottle of good Australian red if they do!!
Hehehe.... And there are plenty of those, for sure! My idea, though, was more of a virtual swift boot up the jacksie! ;)
Marco.
Can you make the message part of the registration process?
All you have to do is send an auto respond e-mail as Dave sez in BLOCK LETTERS BOLD WITH ONE OF YOUR FAMOUS SMILEYS DUDE
We already do that, guys. The problem is that people don't bother reading the instructions in the email. They simply gloss over those and click on the account activation link therein, and then afterwards post wherever they feel like on the forum! :rolleyes: :rolleyes:
Marco.
Try 72pt bold text in the e-mail, and put the activation link below it. Should be pretty hard to ignore :eyebrows:
Good idea, mate. Mention it to Nick in the mod room, will ya? Just in case I forget :)
Marco.
Believe it or not VB generates it's system emails in text format only. I will work on some fancy ASCII emphasis to make sure the requirement of all new members is the first thing they see, with a nice box round it if possible, so there's no ambiguity...
I'm liking the results... Hopefully, that will now keep the 'miscreants' in line! ;)
Marco.
At the risk of sounding like a newbie-vulture, I'd be interested in trying this.
Ever since first installing the 750D, it kinda baffled me that when tightening the screw within the collar, you could tell the tonearm wasn't moving in an exact horizontal line.
Not that the 750D hasn't done it's job well since, but this thread has convinced me this could be a notable improvement.
If someone would be interested in selling me one, I'd be delighted. Thanks.
Have been contacted by a forum member with a spare one. So, for now it looks like I'm set. Thanks.
Coincidentally, the fabricator has been in touch today to tell me that the production run won't happen until February; also that the material costs (eg for the aircraft grade alloy) have risen, which means a massive price hike of some £3 per collar.
Sorry about the delay and wait - there's not much that I can do about it, but this fabricator's work is outstandingly good, so I don't wish to look elsewhere.
If there are any spare? Could you put me down for one.
I should have plenty. Can you PM me with your full name, postal address, e-mail address; and whether you would like a black or natural alloy collar.Quote:

Ronald.
Just get involved here on AoS and do some more posting, then when you can PM, please send me your details.Quote:

Enjoy the forum, and the collar, if you get one! :cool:

Dear Hugo,
Can you please let me know if it is still possible to get the collar?
Alex.
Should be fine, but please note that they will not be ready until Feb 2012. Can you PM me with your full name, postal address, e-mail address; and whether you would like a black or natural alloy collar?Quote:

I have used your collar for a long time now and been very happy with it. Am I right that you are now selling black ones as well, when they arrive February 2012? Is this black same shade as the Jelco black color is?
Juha
Hi Juha
I can't say whether the black will match the Jelco, mainly since I don't have a black Jelco. In any case, I shall accept whatever advice that the anodising people give me, to ensure that the black finish is as good as the clear anodised collars.
Do you want me to keep a black collar for you?
Ha - now you know that's not what I meant! :eyebrows:Quote:

The reason i ask, my Armboard (Sound Support) turned up today and when the Jelco is fitted there isn't 1mm of spare space.
Thanks in advance.
The custom collar's radius is greater by exactly 1mm than the original - this was done to accommodate sunken bolt heads. If there's not 1mm clearance at the edge and no way of carefully machining or filing some metal away, then you will have a problem.
Hi Hugo
Is it still possible to get one of your collars?
Damian
yes - PM sentQuote:

Hi Hugo
Can I get one if you have spares ?
Thanks,

Should be OK - please PM me with your full name, postal address, e-mail address and whether you'd like one in black or natural alloy.Quote:

If its not too late, I will send a PM with my details.

Please PM your details and I'll confirm later.
