Try this if you can't source exactly what you are after. Cut the back part off. This is a good source for all sorts of marine products. I buy from them regularly.

Oh my god, stock removal is not the way to approach that job. For a shop to start off with 4 in solid bar and turn it down .....well.....um.....I wont say any more.

Weld square plates onto the correct tube and then turn it all down and buff will bring a product identical to the picture of what is desired. Add holes.
Not that hard, given a lathe and the ability to weld stainless and a high standard of workmanship.

What would one feel is a fair price for a shop (or an individual) to produce 8 of these?

The OP has absolutely no idea......not a clue.....what say the collective mind of the cruisers forum? What is a fair number?

I'm based in South Australia (probably half a world away). Thought I'd post our local source for this in the hope it helps someone in future if not our original poster:

These guys are great to deal with, nice family run local business.

Or of course if they are required in AL then it's basically the same process except for anodizing after completion.
Quickturn anodizing in TN has been great in the past but obviously longer time and anodizing cost.
But they are actually pretty Quick.
So how much per unit in polished stainless and how much in anodized AL?

It would be quite simple to weld a tube into a flange, fill-weld the joint (hip) with a MIG torch and turn the weld down on a lathe to exactly replicate the image presented. Polishing the end product is a simple task.

If you were in my town and provided the material, I would weld/machine those up for you as a favour. Machine shops would quote obscene amounts of money for four (or even 8) of those in the hope of seeing you walking out their shop shaking your head. For them, the term “mickey mouse job” comes to mind.

Just for interest, you do know that you should drill a hole in one side of the inserted tube and use a long (grub)screw that goes right through to the other side of the tube to tightly pinch the tube without crushing it?

They claim they can’t weld it.

Whitewater marine does custom stainless and is very reasonable

Define reasonable. Looking at the OP's pic, a 3 inch diameter version of that.....define a reasonable price in your opinion.

If you care to of course.

This is a good find actually. Wow

I will say that 6 stanchion bases custom from Garhaur priced two weeks ago approx same as what you want but 1.5 inch dia tube was $450 plus tax I imagine but with a 4 week wait. I agree with the previous posts that that garhaur is both excellent and well priced.

I knocked them up because the 4 weeks was a problem.

The 2” version in 316 was $26 each

They did custom stanching bases for $55 each and a custom folding boarding ladder for about 600

Did you just draw that up girl this thread??

Thank you so much for taking the time to create a picture of them in action

I’m trying to avoid the stub flanges. There are some stub flanges in fiberglass that would be perfect but I was trying for the nice look of one of these stainless or aluminum ones to act as a collar for the 3” OD tubing I have to mount.

The “collar” is inside, not visible, nor are the welds.

Hmm, I find some of this interesting.
I cant imagine the OP will get "traumatized" by my thoughts on this, I feel it's pretty much on topic. If he is, simply say so and I will desist.

No one will put a price on what they think a fair price of one of these units would be. A custom made unit. Hmpf.

We know a 2 inch unit, likely mass produced in china, off the shelf cost $26. Presumably plus tax. Fantastic price....nigh on mindblowing actually.....if you think on it for a moment.

We know a 1 ,5 inch stanchion base cost $55, presumably custom, presumably plus tax. Over double what the OP paid for his 2 inch unit......and also an excellent price in my mind.

So were i to have a workshop in my backyard that contained mid size lathe, the ability to weld stainless, say mig and arc ( thinking on TIG, be fun to learn more skills) , a cold saw, good drill press 2x72 belt sander , buffing machine .....and all the other misc bits and peices like belts,buffing pads/compounds,drills,shamfers,316 arc rods,high speed tool cutters...etc etc etc what would I charge to knock one of these up?

To very exacting standards i get the impresion.....not the slightest blemish.

Well, how long would it take? I am going to ballpark it at 5 hrs. maybe 4, but I would say 5.....just to be safe.

The material. I dont have exact dimensions....so about 4 1/2 diameter 1/4 plate. Remember it doesent start round,,,,nope, gotta make it round. And about 2 1/2 inches of 3 inch daimeter pipe. Hmpf? I am going to say were I to waste the time pricing it at online metals that would likely be $50....or more, but lets say $50. We wont even think on shipping and tax.

So if I had about $10,000 bucks worth of machinery in my garage, and $50 in material and it takes me 5 hrs to do the job.

Lets say I enjoy this work ( which I do, because I dont need to do it most likely) so would charge $50 in labour. Stupid, I know, but beer money.
So....after all that......

I would say $100 a piece would be an awsome price. $150 a piece would be about right.......and $ 200 a piece a bit steep.

And those numbers are what I consider. Imagine what a business has to pay in expenses on top of what I have: Rent, insurance (likely multiple) workers wages and expenses (workers comp etc etc) power bills, licensing.....and I am sure there are bunch more.

They would likely have the advantage (like me to be honest) that they either have the material in stock or do not pay online metals prices.

All very interesting stuff to consider when someone asks "how much do you think this item is worth custom fabricated by some one (or company) with the machinery and skills ( not insignificant) to do the job to an exacting standard".........and not a single response.

hmpf.

I know. I saw you drew a stub flange (collar inside). For styling, I’m trying to do collar outside so it looks more appealing the the dead end of a support column sitting on a flange.

I already bought the 8 (qty) 2in ones from this source in the original post.

I want to try to match that style if possible, even in anodized aluminum if necessary. It frp would be fine too.
