Scott has it pretty much dead on. I'm not sure of the exact figure, I'd have to sit down and work it out but its more than I wanted to spend that's for sure.
interested in how much you need to spend on and above base machine
seems like there are add ons that are nessacary for your desired wookworking
be great to see your finished concept
best of luck with your project

Finally the new gantry arrives. Its taken over a month but it looks to be worth it. This one is much more substantial than the previous design. The weight of the gantry without spindle is 60kg. Nearly double that of the last. This did have a downside though - it was difficult to get back on the machine even with two people lifting.
Good news is there's no play in the Z axis any morel
Now I've got to re-wire everything, finish the control box, complete the door modifications and after that I should be ready to go.

Crikey, that looks like overkill.
All that mass will slow you down you know 😉
Is the Z-Axis stepper lifting the full weight of the Z-Axis? I fitted a constant force spring so the weight was balanced - the motor only moves it up and down, all the force is used for motion, rather than lifting against the dead weight.
You are much more likely to step loss coming up without the constant force spring. But I guess that is under no load, you are lifting the tool out of the job, not plunging in.
And hey....where's all the crap in your shed? Mine has junk everywhere..bikes...wood..tools...electronics....half built speaker bits...last seasons garlic harvest.....mdf dust...******* everywhere..
Don't forget dust extraction. You really can't run without it. Well, maybe you can in your enclosure, but it will all get flung all over the lower bearing rails.

Its overkill for MDF and most wood but will pay dividends with alu.
The electronics have been upgraded to help offset this.
The front plate and the spindle are the moving parts. I don't have an exact figure for the weight but at a guess I'd estimate no more than 15kg. The manufacturer designed and built the part so I'll have trust this is within the capacity of the stepper motor used to drive the Z axis.
I see. On the flip side the spring appears to also gives the stepper motor a harder time when plunging because you'd no longer have the addition of weight helping things along. I can't see a problem providing the motor is up to the job. If its not I'll have to get them to take a look at it again to see what can be done.
That's not the shed. I do have plenty of crap in that though.
I think you're missing that the reason shin can swing toys like that is that he does rather okay at the day job. His brand of perfectionism usually goes hand-in-hand with career success.
badman:
I don't doubt that. I think it would be more a question of passion. I don't know what his day job is, but it seems like his passion is in designing and building loudspeakers. I didn't recommend it because I thought he was broke =)

I wish I could be that pro one day 🙂
Very inspiring to see what other are doing and what one can achieve.
I have been following a couple of shins threads so far and I must say that he is definately someone to look up to and learn from, very resourseful individual and is willing to explain too 🙂
Shin, mind sharing with us what you do? If not we understand 🙂

Well, having worked in audio since the clinton administration, I could certainly help him with some how-to on making a small fortune in audio 😉
Some small progress on the machine.
The rear doors have been modified to a two piece sliding design from the original double doors. I had to do this because space is tight and that made it a right pain in the backside to get in there.
I've also fitted a larger e-chain to the gantry as the original was far too small for the spindle plumbing and various cable for spindle, home switch and stepper.

that thing is insane! you could build a small house from solid billet in that thing. or with the addition of a 3d scanner you could comfortably self replicate another machine
Well, I'm certainly envious of your great machine there. Having one of those would really help. Well done indeed sir.
Also I wanted to thank you for the inspiration. I have been struggeling with a solid ash box lately that has been a nightmare to construct. When I saw your drawings I decided to give up on it for now and do something *ehm, cough cough* "similar" to your design but smaller. I hope you don't mind. Not for any commercial use of course.
I took some fuzzy pictures of the work in progress with my phone. The idea is to paint them glossy white except for the chamfers on the baffle, they will be oiled instead. The box on the right is the old nighmare. Solid wood is fun and all but it's a pain to work with, and honestly the new shape is a lot prettier.
