Once converted, how much are they worth?

[Noah]

Hi, I am well on my way to CNC converting my third mill. It has become time to sell the old one, but I have no idea how much to ask for. I put about $2500 into it including the price of the mill. It has zero backlash screws, G320's, 60 VDC brushed servos, etc. Everything there is newer than 6 months old. At first I was thinking of asking about $3000, but then I noticed a manufacturer selling converted mills identical to mine on Ebay for $5000+200 shipping (new) and people WERE ACTUALLY BUYING THEM. I only noticed one that sold but man, for that price you can get a used Bridgeport. So has anyone listed a mill like this on Ebay? How much is a mill like this worth? Thanks

You should get more than the sum of parts if you can document that it's a sound conversion. I would make some covers around the belt drives, that makes it look much more "finished".
Remember not all have the space and floor loading capacity to buy a used BP.

Good idea, I should do that. Yes, I figured it was worth more than I put into it. Any idea of a rough figure? I mean, assuming you wanted a CNC mill like this and you had my guarantee of no backlash and repeatablility within .001. From the pics, what would you pay for this machine? Thanks for the input.

Selling CNC mills on eBay is brutal at best; I wish you the best of luck. Also don’t rule out the use of a shill (the other guys) on the bidding it’s more common than you think.

BTW. Start the bidding at about $3500 to $4000. It should go.

I my opinion the downfall to buying a conversion is lack of support, documentation and replacement parts. If you have trouble with the control or machine it now becomes a logistic headache for the new owner. They would have to source parts from multiple suppliers or reverse engineer custom components as well the electronics could end up being a nightmare.
On the plus side the new owner would probably gat a machine that is worth a lot more than they would likely pay for it.
Just my 2 cents.

Looks like a sound mechanical construction.
Without chipcovers Limitswitches cablerouting etc it is still a bit of a work in progress.
Dose it have Ballscrews on X & Y axes?
Any thing done to reduce Backlash in Z axes?
Dose it have a controller Box, Powersupply?
From what I see I agree with Aarons estimate on what you could get as is.
A fully finished Conversion could get you more.
How much time do you have into this?
Good Luck
