Have you ever bid on something online as the auction was close to closing and the price was silly low?

I did that last week

I now have a 7foot tall 1.4ton milling machine

2 minor issues to sort out

How to get it into the workshop which will be solved reasonably easily

The 2nd issue

Its 3 phase and i only have a single phase supply

Anyone here a dab hand at setting up variable frequency drives?

I have a couple of old router brick transformers, is it three you need?

Ive got an old one which keeps cutting out. I needed my ramp working so just bought a replacement (also a last minute ebay deal) however believe the old one could be repaired. Welcome to it FOC if you like?

Looks tiny but works a two post car ramp with ease.

Once back in UK Ill get the make. Its a digital one so doubt it can be repaired at home btw.

Might get N3 on the ramp and have a good root around underneath when you get back Craig.

Can you still do a small fibre glass repair and spray can?

I want to post 'ttiuwp' but I don't even know what to expect

Car is with Monty and forgot to take one.

Twat blocked me in at Hospital and I had to do an eight point turn. Front left lower corner scraped a 6" kerb, just needs a skim and a can spray. Dicksons may do it for me for free.

Yeah, ramp is working so no problem although to be honest for the loti its probably better over the pit as I dont trust the two poster so much with engine weight at back...

Obiwan had a couple of big weights he stuck in the passenger footwell to make things less tippy

Not that really helps me with VFD and DC brake injection

I have a static convertor running to 3 sockets for the mill, lathe and shaper. It saved buying 3 invertors and works fine as only one machine is ever running at a time. I only used the static convertor because it came with the lathe.

I had a Chinese 2.2kw VSD/Invertor (1-3ph) running the dyno fan which was easy to setup, gave soft start and variable speed. When the bearings went i just replaced it with a single phase cap start/cap run motor.

My point being, if i was in your situation i would save money from buying an invertor and just buy a new motor especially on a mill where the starting torque is fairly low.

Well we are making progress.

A wee whoopsie with the power feed as it was 110v not 240 v and the magic smoke came out. But i have tested the head by wiring it into the lathe power supply. And the machine is in its new home.

Now this isn't my first milling machine

Due to a strange set of circumstances i have a chester 626 mill about to go for sale.

I have no idea what it is worth as i bought a colchester student lathe plus accessories for £1500 about 6 years ago.

The accessories turned out to be a 4 jaw chuck, a box of mills, some cheapo tooling, some rusty spanners, a clapped out gas cutting rigs, 18 month old chester 712 bandsaw and a chester 626 milling machine.

Fast forward to last month i placed a stupidly low bid on an Ajax milling machine and i discovered i won.

So it is time to let the chester 626 mill move onwards

The thing is

I have not got the foggiest what it is worth.

I would normally stick it on the bay of fleas but that is normally a huge amount of hassle.

So i would rather it went to a local forum member at a good price to pass the good fortune onwards, but not too cheap.

So what do we think it is worth?
