my simple router

[flye]

earch for new world centre... soon lin is just beside it...

are you cutting long strips of wood??

[Wongster]

Not really. I try to work around the standard length or width of the softwood I got from Ikea. The longest side is around 500mm.

Are you able to saw thru squarely? This is one hack of a job for me at this moment. I bought a Wolf jigsaw table, a Black & Decker Workmate 225, a B&D jigsaw, a handsaw, a level as straight edge, and 2 F-clamps. I thought that using the jigsaw table with the fence would help me up the learning curve. Boy I was wrong. Its so difficult. I messed up my study with saw dust and no result. What a pain. How to sleep tonight?

i started with a B&D jigsaw, bad move, the blade is too short for the 45x45 to do any good straight cut, ended up with a few cut at different angle round it. that is where the handsaw comes in. and a lot of filing.

i used to cut inside the house, now i cut outside, easier to clean up too.

sometime i will do up a rough paper or cupboard model for visualization.
really help to spot problem ahead.

the masking tape is a great idea.

updates

took me 1/2 day just to complete front panel, the back will have to wait.

got a bigger hobby box, not big enough, have to mount the card at an angle.

yes, messy wires.

have some issue with the z axis, keep flexing in the x axis direction,
guess it is too long.

a 3mm mill bit is use for the cut. got it from Mike long time ago.
the feed rate is set at crawling speed, and a lot of doublesided tape is use.

with a bit of filing and cleaning up, the front panel is done up.
not nice, but is usable.

Where did you get the box? The job looks nicely done despite the placement of the card.

What are you using as the spindle by the way? Saw that you didn't do up a mount for it. Akan Datang?

I'm having hard time figuring how to mount my hardware on profiles. The whole setup makes the gantry too big as compared to the base. Back to the drawing board for me.

i got the box in slt, think its call "hobby box",
way cheaper then the metal enclosure, cost me $4.50
easier to work with since the front and back panel can be remove.

the spindle is a black&Decker RTX rotary tool, can use dremel bits.
will be using as it is for the time, need to solve the flex on the z axis first.

my frame is not completed yet, no clue how to secure the y and z axis to
the profile, still using cable tie, and it will shift under stress, can only do
light cutting for now.

take your time on the design, once you are comfortable, then its time
for the muscle to work.

Hi Guys.

What are your choice gutting tools.. I've read that people are using Makita router, and many have sing high praise for Kress (Higher end version of Dremel?).. But how are these stuff compared with those Water-Cooled type spindle that have to be run through a VFD?? and what's the difference between a .8KW and a 1.5KW??

Thanks..

[pilot_bear]

for me, any cutter with at least a manual variable speed control,
reasonable torque and acceptable range of cutting bits is good enough.

a spindle design for router will be save you a lot of trouble.

as long as we don't over work the spindle, air cool is reasonable.
spindle speed control method is more or less personal preference.

higher rating = more power, nothing special.

kress is a good router motor, much more power than dremel.

one thing i like about kress is the collet can let you fit tools up to 8mm dia.

the others (dremel, RTX, proxxon etc) can only fit up to 3.2mm tools which can't let you do anything decent.

the runout of these tools are nowhere near those VFD controlled motors.

[Wongster]

Any lobang as to where to get those VFD spindles locally? They seem expensive....

[tucfaz]

Not sure about local supply, but have read that those <$1K made in China water-Cooled spindle does the job really well..

Kinda intimidated by the word "water-cooled". Dun understand enuf to hook it up at this moment. From the ebay store I bought my bearings and linear motion stuff, saw that that guy is selling them. Lowest price at about USD500+.

Bought a bosche trimmer today at around $80+. A very basic model with single speed and fixed base. The intention is to flush edges of the board I'm using as base for the machine structure. All these tools really take skill to use them. Got mixed result from my trial. Will have to practice more.

The idea is to use it as my spindle after the machine is built. From there, I'll move on to a all aluminium structure.

[tucfaz]

My understanding was that it's best use a spindle that will give the least flexing, as product like Dremel will flex when loaded as their bearing are house in plastic casing.. Hence, for a nice clean cut on metal, people usually recommend Kress or a high wattage router or better still water-cooled spindle for faster, deeper clean cuts..

Hope members with better experience will correct me as I'm still very much a noob..

[Wongster]

Ultimately, I will get a proper spindle. For now while experimenting, I'll mount my dremel or the trimmer. Budget already over-ran many times over...

Any idea how to deal with the water-cool part of the spindle? Really running water thru it?

heat is transfer from the non moving parts of the motor to the passageway of the cooling liquid, and the liquid is cool via some other means.

something like wrapping an metal tube around a motor casing and pump cool running liquid into 1 end of the tube, the heat from the motor is transfer to the metal tube then carry away by the liquid. the warm liquid then run out from the other end, cooled then re-cycle the liquid again.
