It is cutting! Angle motor drives, pumpable gasspring #14 -Soderhamn, Sweden
 

Hello all,
here is a picture of my MechMate , started to build in sept,2007
thanks Gerald for the plans and all of you on the forum for inspiration

Hasse

Nice work Hasse, bet you on what you’ll be doing/thinking this week end !!
Let us know your evolution.
White, Nice touch !

Very nice Hasse,

Keep the pictures coming.

Welcome Hasse,
Looks like you are off to a great start. Keep the pictures coming as you finish your beast. :)

Hi Hasse

It must be winter in Sweden - your poor MechMate is frozen! :)

Very nice ice sculpture Hasse.:) Been lurking and building without a word:p.....Glad you decided to share. :D

Hasse, could you show more details on how your table is bolted together? It looks very neat.

Hasse,

Nice looking machine. Logo in solid blue.

From your photo it does not appear that you have attached the rail? Yes, how did you bolt it together!

It seems that Garage is the obvious birth place for most MM's :)
Nice work Hasse.

Yes its winter in Sweden maybe my M M turns into blue when spring comes
in may sometime,or it melts away we'll see :) anyway here is another picture

That construction is nice and simple. Very good!

Still frozen
 

This weekend i will get it up and running

Hasse,

What is the bottle for?

Machnie looks great.

wow, 15-16 months of construction.

white looks good... and the sweedish blue on the logo. nice!

what kind of reduction are you using?

Hi Hasse, it is still dark outside that window - how far north are you?

Your MM looks like it belongs in a hospital surgery - nothing wrong with that! Looking forward to hearing about its first cuts. :)

From what looks like sawdust on the far rail and cuts in the spoil board, I would say with a few logos this man needs a serial #????? Am I right :p or wrong :(?

Nice spotting JR . . . . and there is a logo on the side of the Y-car! He gets #14

Hasse - would be interested in knowing more about the gear reductions on your steppers.

Hasse,

Congratulations on #14. Well done!

Thank you all
The bottle is for the modified gasspring, with a bicycle pump i can adjust the
gasspring to the weight of the spindle



Added by Gerald:


A typical gas spring holding 15kg on its 8mm rod is charged to 30 bars (400psi) Do not saw it open to see what is inside!

#14
 

The reduction is made of gear wheels from angle grinders.

Hello Gerald
The sun gets up 9,05 down 14,47 its dark allright
Soderhamn is 250 km north of Stockholm ,and yes i have made a testrun
without e stops :o but it is not recommendable your helpless if somethings go wrong i learnt the hard way.
Thanks for #14

Hasse:)

That is some VERY clever stuff!

Are you happy with the overall performance of those Nema 23 steppers? (What is the gear ratio?)

OK Hassee - since we already see those gears working for you - I am presuming you have thought over the backlash issue - let us know more on how you have countered it -

when I hold a grinder in hand and turn the wheel I can see a considerable amount of backlash - so I am a bit eager to know more on these gearboxes - also can you share the design of these -

Frozen - 16 C outside
 

Hello Gerald , Irfan
Yes its dangerous i used a broken gasspring with no pressure in it and
replaced the piston in the cylinder with one with a rubber o-ring
the cylinder is 18 mm that makes 6 bars to hold 15 kg
The motors and gearboxes is used only 10 min so i cant say if they vork well
the gear ratio is 3:1 hopefully i will make some dust tomorrow,sorry about my English i hope you understand

Hasse

Hasse,

Congratulations on Serial #14.:):):)

What is the size of your table?

The Build Log spreadsheet has been updated and is available here.

Regards,
John

Thanks John

The table is 2500 x 1200 mm

Hasse

Nice to have you finish your table as well. Did Father Christmas deliver it over the festive season ? Now we want pictures of what you are cutting..;)

Great Job Hasse,:)

Milk truck white, Congrats!! on no 14.
