I've seen the IDL's that look like a retarded drill press but never a cnc one. There are some advertised for sale at a machinery dealer here, I'm just interested to know what they are like?

Cheers,
Greg
Didn't IDL go out of business before the CNC thing got legs?

I saw one of these on Ebay a while back. I don't think it was a true CNC machine. Might have been and early NC but from the looks of it, it may have been a mechanical copier. IE, it was built for a mass production rebuilder doing the same head over and over.

That would make sense, it didn't look terribly versatile fixture-wise.

Hell, that seat & guide machine looks ok.

I'm in the same boat as Greg (proengines), I use my old RVR, it's a good old machine, mine is updated with ball drive tooling etc, but it really needs a proper rollover fixture rather than it's tilting bed & could use a speed controller to drop spindle speed for larger seats (chatters a bit on bigger seats).
The time & $ I'd spend to get it up to where I want it may be better spent on a new machine.

If I was to sell it I'd be 1/2 way to the cost of the chinese machine, if they are decent it's not a hard decision.

Being a 1 man show I cannot possibly justify the cost of a new 'brand name' machine, even a good second hand VGS20 is worth extortion money over here. I'd definately look at the chinese machine as a option.
A lot of machines or at least components of them are made in china anyway, may as well face facts & just buy the whole thing there without paying the brand name mark up for much the same thing.

Greg - wonder if they knock a bit more off the cost for 2 machines!

Good question Tony, I might have to check and see. If someone else bought one as well and they were no good at least I'd have someone to cry into my beer with.

I've been looking for a good used Serdi 3.0 but they are like hens teeth and still in the mid 30's used. I love my little serdi, it cuts a beautiful seat but thats all it does.

I suppose the other option is a good rollover fixture for the RVR's, one of the T&S or Sunnen style ones would be the go. I already have a vfd for it, just need to wire it up. Maybe one of the T&S level setups as well.

I got a price on a sunnen rollover jig a while back - it was something like $4k.

F**k that!

If I had the time I'd make one, but sadly....

The last VGS20 I saw for sale was asking something like $35k.

Go on, make a rollover for your RVR, & make another while you're at it! - they'd be pretty damn close to a VGS20 with a rollover & speed controller, just lock the bed up solid, throw away the original parallels & bolt the rollover fixture on some risers direct to the bed.

One of those sunnen style digital levels to set up & you'd be away with a real nice machine for 1/4 the cost of a SH sunnen.

This for the guys in aus-land :D
Whoever you guys have been dealing with there should be shot.
I bought a new vgs20 in 2007 and paid 18,000CDN for it fob my shop.
Taxes in delivered With std tooling.
If you are serious there is some deals to be had here in canada.

I have seen lots of them with tooling packages for 12000-20000US but transport to Oz must be 1500 on the boat from here.
I know of 2 machines currently available for 1/2 of what you have been quoted

PM Me and I can give you the contact details

After a bit more thinking, maybe it is time to make some rollover fixtures because the RVR is really very similar to a Sunnen apart from that. T&S has the digital levels on ebay for $600. For anyone who has no idea what I'm talking about, this is a picture of the Repco machine below:

If you do it I'll buy one & you could probably sell them to heaps of little guys running the RVR's - ie. literally dozens of us.

Guys like me will 100% jump at the chance to have a machine that does pretty much anything a sunnen will do at a fraction of the cost with a simple update to their existing machine.

I hope the buyers of the Chinese knock offs have better luck than Serdi customers had because the motor in spindle idea is like cutting seats with a dull jacknife. I have never seen one cut seats without chatter and certainly not round.

Whoever took them a machine took them the wrong one, oh well I guess there is some positive Zen in this world.

BTW, The Repco was the original machine Pierre Harmand looked at when he was designing the Serdi 100. It incorporated the heavy structure and spindle assembly with a air floated sphere assembly from an orbital seat and guide finisher.

As far as the IDL CNC, the made a few of them and there as still a couple Robots running in Canada at a VW plant that manufactures many of the TDI heads, and gas heads for VW North America. They are a pretty cool machine but prone to significant wear if not maintained properly.

I am hoping to have a roll-over fixture ready in about 6 months as I have seen the need for many of my customer with fixed base machines. Won't be cheap but should be less than a Newen.

Pro Engines,
PM me if you want an awesome 3.0 in like new condition only used by Grandma-ma. It is really a slick piece as I just serviced it and might take it on trade. Owner just spent about $5k getting it updated, you can pm me or e-mail me if you're interested.
More is always better!!! Most of the time.
