Wrt 1-start vs. 4-start, take a look at the posts at the end of this topic. As for the weight, since your spindle listing only included the shipping weight, I did a search for the weight of 7.5KW spindles. The pages I found had weights between 14 and 18 kg…roughly 30 to 40 lbs.
I honestly would be concerned that as soon as it would start up, the rotational forces would flip the gantry off of the table.
I was thinking rip the plastic in 2, but that is an interesting concept as well!
Yeah definitely too big, all are valid concerns. Gonna return it. It’s a god damn monster.
How about this guy, he’s only 3” wide
Consider making a Core X Y Z CNC where the table moves around a fixed monster spindle

So whatdo you plan on doing?? Cuttingsteel?
Whatever I need to, I was told 2.2 might have issue with facing bits.
That monster would cut through anything I’m sure. I don’t even know how I would even go about mounting it on a gantry
Where is the advice coming from?

A real man doesn’t settle for less than a 7.5 kW vfd on a 2 ton machine to hog out steel pockets 2" deep, 1/8" stepover at 300 ipm.
Which is to say, a real man doesn’t get anything done other than looking at magazines and fantasizing.

Buddy whose a machinist, he’s got like all the toys though. Last thing I saw him make started with 80lb block of aluminum. He’s uh… a bit hardcore to say the least. He’s got haas and tormachs, and just got his 5 axis going. He’s looking to get a datron cube I think it was.
I don’t need anything so hardcore though. Will that 2.2kw fit better?
I do want to look into that different lead screw still though. Right now on my lr2 if gantry is too far to the left the z seems to not hold and will come spinning down.

“Hey buddy, how was the weekend at the track? Set any more records? Great! Say, I was thinking about maybe giving the lawn tractor the once over, since it hasn’t seen the working end of a wrench in a few years. Any tips? A blower and supercharger, you say? Hmmm…”
Lol crazy part was it got machines down to like I think it was 9lbs. Would send pics but can’t because of nda shit :<

So that 3” spindle should fit ok?
The only spindles we know work are the routers we have tried (the makita and the dewalt). I was sure the 6" one wouldn’t, but I don’t know anything about fitting or using a 3" spindle.
Thanks jeffe, it seems I will be the test subject for it then :>
I will let you guys know how it goes once I return this god damn monster

The 3” shouldn’t be that crazy, it’s only .5” bigger than makita.
So maybe only a small popcorn :>
I’m probably going to build out storage for under my table before I upgrade, I’ve got too much crap everywhere. My desks are overflowing, toolboxes aren’t enough.
Plus I’m gonna have to flip around my whole basement so cnc can get at that 220v line and getting electrician to hook it back up.
I will try to make my gx16 plug mount for the LR3 though, so other people can use it. Those plugs would have saved me a lot of electrical debugging when I first made my LR2. So hopefully it can help people making first LR3 too :> Plan on starting that when I start cutting up some 1/2 or 3/4 MDF scrap lumberyard gave me to test my 2060 extrusion y axis.
So don’t go expecting big developments on spindle for least a few weeks if not a month. Trying to make LR3 core out of PCCF and it’s been a bitch.
And thanks for everyone’s input, gave me some laughs and good advice :> and of course jeffe because I wouldn’t have gotten my LR2 going without his help
