Small turned metal parts

Post by tallstory »

Is there anyone out there who can make small replacement parts for arcade machines? I'm looking for someone with a lathe and a modicum of experience to make some parts for some of my arcade machines. The companies online are into CNC and everything costs a fortune as they want to make a thousand. So I'm looking for an enthusiast or a small family firm who is happy to turn out a single small item or two.

Strewth, your idea of "small replacement parts for arcade machines" and mine differ.

I don't know enough of what's involved to meet your needs, but even if you were able to supply accurate and detailed drawings for a competent engineer to faithfully reproduce your items, I'd still expect the costs to be chunky.
Anyone worth their salt and in possession of the equipment and facilities will have overheads that dictate a minimum hourly rate, before you get into materials costings etc.
Do you know this story?
The Graybeard engineer retired and a few weeks later the Big Machine broke down, which was essential to the company’s revenue. The Manager couldn’t get the machine to work again so the company called in Graybeard as an independent consultant.

Graybeard agrees. He walks into the factory, takes a look at the Big Machine, grabs a sledge hammer, and whacks the machine once whereupon the machine starts right up. Graybeard leaves and the company is making money again.

The next day Manager receives a bill from Graybeard for £5,000. Manager is furious at the price and refuses to pay. Graybeard assures him that it’s a fair price. Manager retorts that if it’s a fair price Graybeard won’t mind itemizing the bill. Graybeard agrees that this is a fair request and complies.

The new, itemized bill reads….

Hammer: £5

Knowing where to hit the machine with hammer & how hard: £4995

I can supply drawings - no problem. Anyone who has a lathe could do them so perhaps I should buy one. That would certainly add to the cost.

I had a contact (a retired model maker) but sadly he is now too ill to continue. I'll try searching the model maker hobbyist forums.

I suspect that is the issue, finding a fellow colleague who can help as I suspect there are many who have the skills seeing the work done over the years. I often have had a similar dilemma when considering investing in a expensive tool, will I get use of it and will I fail miserably to master it :HaHa:

Put some drawings on here and people will then know what skills they need. I’m an engineer with a couple of mills and lathes, but I like to see drawings before I say anything about how easy or difficult they would be to make.

Geordy, I have attached a drawing so you can see it is fairly straightforward machining and not high tolerance work. Hope someone steps up because I contacted a commercial company and they wanted shed loads of money to do it.

Twenty minutes work if you have a lathe and a drill.

My point being it shouldn’t be a prohibitive price.

Unless you have the tools and skill to do it yourself, or know someone willing to do it as a favour, any one-off job like this will be relatively expensive.

Anyone doing it professionally, and therefore needing to make a living wage, has to take into account (on top of the estimated time for completing the work) time communicating with the customer about requirements and understanding technical details, sourcing and cost of raw material, setting up tools, wear and tear on tools, plus the time and cost of postage and packing. So the unit price of such simple items does tend to be prohibitive unless required in quantity.
