Thanks guys. I was thinking no more than 40% just wanted to make sure. Just don't want to get into something just to have it go down in a few months etc.
I think 40% might be high for 6 yr old equipment.
I would look closer to 25% or less, it's electronic equipment and too many things can need replacing.
If he has a porc furnace that is $4000 new today $1000 is the very max I would pay and that may be high.
How do you know he has never shut it down. He could have had it idling at 1000 f for the last 6 yrs.
If you dont buy, its going to sit in his basement till his wife makes him take it to the dump in 5 yrs.
Anything that is not name brand is worth very little. Pennys to the dollar.
High spead hand peice, assume you will have to replace the turbine which can be 50% of the value.
Eletric hand peices assume either the hand peice the electronic box or the foot control will die soon.
I wouldnt pay more than $200 for a 6 yr old electric hand peice that cost $1000 new. And that may be high, think of how many thousands of hours are on that hand peice over the last 6 yrs.
Vacumns like a Vaniman, assume the motor will blow any day and you are buying the box and hoses with out a new motor. Assume that vacumn has ran non stop 8 hours a day 6 days a week for 6 yrs.
Mabey you could bundle items.
Offer him $1000 for that 6 yr old Ney Centurian furnace and vacumn pump.
($3500 new) if he throws in the handpeice and the vacumn.
I dont think they make the Centurian anymore it is the QEX now making the Centurian obsolite?
Assume you will need a new muffle on the furnace and it may not be drawing 100% vacumn anymore, thermacopule is ready to go,front electronic panel is ready to go, a new motor for the vacumn and bearings on the handpeice and a new foot control. The on and off switch on the hand peice box etc.
I have some equipment that has lasted me over 20 years ans still going strong, but figure after 10 years used equipment is worthless and you are saving him a trip to the dump.
Except for stuff like a castiing well which is a heavy duty peice of furniture
and you know it wont break or metal cabinets.
A new bowl for a vacumn mixer can be $200 and there is alot of electronic stuff in a vacumn mixer that blinks out.
For a 6 yr old vacumn mixer 20 % of todays value, Mabey 25% if he throws in a vibrator and rubber mixing bowls and spatula and plaster bin and scales.
Model trimmer 25% mabey 30% if he throws in a lathe with a quick changechuck.
Most used lab equipment is worthless except for stuff like a low hour Ivoclar pressing furnace and IMO if he has old equip or if he cant make it in this business you are doing him a favor takiing it off his hands and he should be thankful he can sell any of it because in 5 more years he wont be able to give it away. So I for sure would bundle related peices.
Pay for one take 2 off his hands for free.
Hech its Christmas, send a stamp and I will sent for free
