I think for a commercial version of your arm, ease of use needs to be up there with SQ. The one thing I have a bugbear about is cueing on the record, I think the Nottingham space arm approach with its quadrant lifter, with the rubber block underneath the arm is the best I have used on any tonearm. I use my space arm now primarily as I put ease of use over the SQ benefits which my better arms gives me - due to the PITA it is to get the stylus in the right groove.

Yes a Rega lifter and a positive cueing system may add £30 onto your costs but, from and end users perspective it could be worth more than that on to the final price.

What I forgot to mention yesterday- was a good cueing system can save on needing a finger lift, and in the case of the NA approach they don’t have a clamp to hold the arm when it’s not in use.

How you proceed you need a unique selling point (USP)to stand out from the rest of the arms in the price bracket, the ARB arm on eBay made to order, for little money, upto the Edwards arms which are obviously batch produced. I would see custom lengths, and weights as a good USP. Getting it reviewed on HIFIPIG or such like would attract a wider audience, as the majority of the people on this forum are Yorkshire men - tight as chuff :)

Yes and when you upsell you dont just charge the cost of that, you put youre markup with the upsell. That is standard business Ant, you have to do it business like even with us tight Yorkshiremen where we like a Proper Brew. “Do it for Yorkshire” Sean Bean 2021.

It has no usp, and its finish is not to die for. I cant achieve a very very good finish with the tools i have
This conversation has been very instructive, i dont think ill bother.
Without somehow being able to invest in a new lathe to achieve a satisfactory finish there is no point. What it sounds like is largely irrelevant if it looks like its made by a bloke in a shed, which it does
This has largely confirmed my thoughts, thanks to those who have replied

What you do Ant is get cnc drawings done and sub the manufacture to a local cnc engineer. Darren did that when he was selling mods he invented to sme arms. Sme complained to ebay though, but his bigger problem was the Chinese bought one and ripped off Daren’s invention. Worse still the local cnc engineers were at about that time being questioned by the plod for making firearms. ermm, he claimed he didnt know what he was making them to become. Darren drew away…..

Its not easy, but nothing is…. its worth exploring subing out production and definately product would then hit the quality level to sell it for £400 upwards.

I don’t think your finish is too far off the mark- depends how long it took to get to that surface finish.

Are you using the truepoint jewel and carbide tips as the unipivot? As at this price point there aren’t many jewelled arms.
For the edge over the competition, maybe you need to look at more exotic arm tube materials, wood or a combination to damped better. I once made an arm out of a magnesium sacrificial anode, so there is scope to being different without it costing you the earth.

Maybe for inspiration look at the German guy who revamps Lenco arms - and what Pete Wriggle does. I think with all your bad luck recently you are probably not in a positive place to consider it properly, I wouldn’t be.

Given your luck, I would avoid machining magnesium :-)

I would suggest you look at making the arm to fit the technics SL1200/1210 MK2 and above.

Over 3 million decks sold, most still in circulation.

Jelco went bust they were the default arm in the past (SA750D).

Huge potential for a decent arm to go on it.

Unfortunately i havent got a 1200 to fit one to, and it doesnt solve the issue with the finish.
I need to address that first before i consider other aspects, and a new lathe that can do what i need it to to start to get towards a finish acceptable to a buyer is probably 1500 to 2 grand. and there is no guarantee that someone would buy it anyway once i have invested in a machine.
I dont have that kind of money anyway so the point is fairly moot

Metal finishing is a trade in itself, but I was surprised how easy it is to get a professional finish on stainless

If you have turning lines, they can be emery clothed out and polished in the lathe.

Scotchbrite disks or wheels for an angle grinder or a bench grinder can give a ground type of finish and look professional, it takes a little practice of course but worth exploring.

Not at all but the fact that you are supposedly a solicitor and you can't even spell correctly does.

I’m currently on the sick recovering from a very serious brain bleed Dave, you still an amoral salesperson raking in profit from things you do not believe in.

Ps. When I worked my secretary checked the spelling , I had much more important work to do

I can get that. After all if a big fat SAS trooper is now a QC someone not spelling a single word wrong doesnt mean hes not good in court. Myself he/shes probably a brilliant barrister from where Im standing. Dyslexic people will always be passed over by rhe good spellers. But spelling is no guide to ability or truth telling.
