The spindle is a Kress 1050 FME-1
Enjoy the video!
Interesting project! It's nice how the spindle has a clamping ring right at the bottom, that makes it easy to mount and perfect for CNC use.
Marius, I'm impressed. On behalf of the TH-cam community, may I award you an honorary degree in practical engineering. First class.
+John Bouttell Cool, thanks man!
Great project. I love the way you used the CNC to build a pattern right in the material to finish up with the flush-trim bit. Great idea and implementation.
your vids are getting better and better. always creative and never boring to watch. keep up the good work mate
Over 65 years ago when I commenced my six year apprentice with the British Royal Navy, the expression on my face was similar to yours when you were about to start "your favourite part" of cutting with a hacksaw. We used steel to make our own tools and my instructor insisted on clamping the workpiece with wood packing all along the length of cut and putting a cloth over the free end to stop it vibrating and damp the noise and never to hold the hacksaw with two hands on one end but use one hand on either end of the saw to guide it continuously and you will not believe this, but he made me lift the saw on the return path as he said that the sliding it back on the workpiece would blunt the teeth.
Seeing your hacksaw cutting action, I must admit, in my instructor's absence, I used your method including the length of stroke as indicated by the paint removal on your saw shown in this video.
Once I broke a half inch Whitworth taps in the hreaded end of a small steel vice I was making and the instructor made me start all over again. In his absence I went to the welding shop , filled the hole with welding and threaded the other end of the U shaped vice. My instructor never noticed and in fact he congratulated me for the accuracy of my fitting of the other parts. Our hardest test piece was manually fitting an H shaped part in a flat -plate made of the same material as the H part. The test included fitting the H then rotating it by 180 degrees keeping the same side as entry and fitting it again , then changing the sides and repeat the test, with all gaps being accurate to a thousand of an inch, as we used the imperial measurement.
Once when I asked why the imperial measurements were chosen , the British instructor told me that is because the number 12 can be divided my many numbers where the answer is a single digit!!!! God bless the British for their logic!!
+Carmel Pule' Hacksaw! Luxury!
+John Bouttell
Yeah, I've been using steel wool on a toothpick scraping away without complaining for 23 years! I'm soon through with my first cut and it feels great!
PinkPonyOfPrey
You were lucky to have a toothpick!
I used to dream of having a toothpick, would have been a band saw to me.
Kress makes excellent spindles. Very nice upgrade.
Looks like that start of a good, manly x-carve. Looking forward to seeing how good you can get it.
Excellent job and explanation!
Nice work Marius! I liked your (apparently) home-made tapping rig.
Looks like nice upgrade Marius!
Love the details, well done.
hope i can find enough time to watch all your good video's
wr from Holland,Henk
Another great vid. even though I don't have a CNC router. You take the time & trouble to explain why etc. which helps. Keep up the good work eh.Thks
Great video. Very interesting. Have to go through your other videos. Subscribed.
Wonderful conversation! And well done too. I think you might want to add gussets connecting acetal plate to AL plate to provide greater rigidity to assembly. Otherwise, you are asking threaded plastic to absorb lateral forces which will eventually cause system sloppiness.
I think you can open the powercord plug (motor side) with screws.
then undo the wire and feed it trough the chain.
then reconnect the plug
very well done. You have a great future ahead of you.
Pretty good results are a testament to your workmanship abilities since the whole process was a little on the shade tree side.
+Leonard Legg Thank you!
Great video mate. Totally understand your love of the hacksaw!
+dashn64 i love my hacksaw sooooo much, i dont even us my angle grinder any more
dashn6
dashn64 you Could have cutter the Alu with your tablesaw
dashn64 you Could have cutter the Alu with your tablesaw
holy crap! hey my name is Marius too! i never see anyone with our name. and you are in to machining! that is cool!
Nice job Marius!!!
Bravo Marius. nice presentation.
Nice job, I like the way you managed your upgrade. I notice your wooden clamps. I have been wooden clamps too. It is always nice to use something you can make yourself. Best of luck to you. Lee Noring
Nice job Marius!
I'm a big fan of tapping too!
Hey Marius, I really enjoy watching your movies, they are really inspiring and fun and have great content! :)
A suggestion, when you drill in aluminum, use isopropyl alcohol as a cutting fluid, it will provide for a cleaner cut and also preserve the cutting edge of your drill bit for longer.
And for sawing off the aluminium, if you have a power jigsaw and a finetoothed blade, it will cut right throug it. Otherwise you should be able to cut aluminium with most circular saw bladeswith carbide tips :)
Pelle Reinke Very good
awesome tools man!
Nice workshop! :-)
Nice video! Good work
Great video! I'm pretty sure your bandsaw would have worked just fine for that aluminum.
Another superb video.
Those holes are only an uncommon size in Germany. It's a 9/32" size. Inches! :)
+Matthias Wandel As a german, I have to say i hate the imperial system.....
Uncommon in metric.
+Robert Hagman
'murican here, I don't like it either
+Matthias Wandel Ah, good to know. Strange design then. Metric nut, metric threads but imperial eccentric thing.
+Matthias Wandel Not only in Germany. We had inches in Sweden in the old days but nothing new is made with inches. Is it the Great Britain countries that still hang on to inches anymore?
Excellent vid!
love your video's
I suggest adding a set of transfer punches to your tool inventory for use at 5:00.
very nice job
You can easily cut aluminum like that with a miter saw, or perhaps table saw.
+Justin Bell Yep... I do it all the time. I have even used used a router, though it does tend to clog the bit. No issues with using a table saw, though. He probably just didn't have the right kind of blade.
+Justin Bell jigsaw mates, jigsaw c;
I have a kress spindle and they are really well made. The bushes was hard to find online but are fairly easy to fit so dont send the spindle away, just do it yourself.
Never had a problem with my Kress, but the brushes have finally worn out (after several years) - I should have bought a spare set. Had to wait for new ones to arrive
@Marius you will find that if you have dedicated cutting tools for Aluminum that have never been used on steel or other materials they will cut the aluminum much better than a tool that has been used to cut steel or other material even the shortest distance. This is also true for Brass. If you test this and find it to be true for yourself you may want to (when affordable) purchase a dedicated (for aluminum) (for brass) set of hack saw blades, drill bits, end mills and any other cutting blades that you will use with any frequency. - - - I hope this helps you and I wish you the best. If you get a chance, please let me know if it works better for you. I hope this helps you and I wish you the best from Houston, Texas, U.S.A.
das schöne ist das es für die Kress spindel auch spannzangen in 6 & 8 mm gibt. abgesehen davon hat sie auch mehr leistung
Nice work.
nice, sharp, enlightening.Thanks Marius !
and bzw, I thought one could cut aluminium with a wood-speed bandsaw, don't you want to try some day ? (I just bought a 1950s wood/metal 143 macgine with a gearbox reducing speed for metal, but the manual keeps saying wood speeds are okay for Aluminium).
Thanks and Keep on trucking ! (from France)
we should all show our care. send lots aluminum so the fun with the hacksaw will never end.
Very nice video and a useful upgrade of your X Carve!
But I think weak point of your mount is the clamp made from HDPE. All plastics have a tendency to flow under pressure (and temperature!). Especially HDPE has a high tendency to flow. If you can not avoid screwing HDPE to metal, metal spacers and large washers should be used, and if you have to fasten metal bolts I would definitely not tap threads directly into HDPE (for the same reasons). Like wood each species of plastic has different properties. For this kind of application I would definitely recommend an other, maybe reinforced plastic.
Wow, incredible!
Mega cooles video, wie immer von dir....
Love your video. I would have used a more robust mounting method for the motor instead of the 2 bolts I would have used a 6 bolt method and made the plastic mounting bracket with an angular portion that utilized the strength of that Aluminum back plate.
It looks very strong but over the course of time and vibration you want as much strength as possible.
You can get hacksaw blades for your reciprocating saw, speeds things up considerably.

Parabéns ,ótimo trabalho
for cutting aluminum I use an angle grinder with a diamond blade, used for stone and tile, other blades can clog up with hot shavings. I also hate using a hacksaw, powertools ftw... :)
Super geile Werkstatt haste da... Hätte ich auch gerne ;)
I know this video is very old, but if you still have the power cord zip tied to the energy chain, then normally you can open all the joints on the chain, and lay in the cords :)
I know this is old as hell but an easy way to get that spindle more rigid is to add an auxiliary support retaining structure for the router. You've got got radial and (a bit of) torsional support, but no axial thrust. Making another bracket under the exhaust ports ~200 mm up is a cheap upgrade
Another great video. Just a word of warning, a plastic mount won't be rigid enough for heavy cuts in harder materials. I don't believe you do such cutting (yet!) so it's not a problem.
I've got a similar mount but made from aluminium and that is still not stiff enough. Pressure from the cutting head will try to induce X/Y rotation on the pivot that is your clamp. If it does rotate even slightly, it will bite harder and chatter, maybe even stall. I damped the radial stress by making a support for the upper part of the router body too. With this setup I am able to cut aluminium and even steel on my router.
Great vid
well done
In the meanwhile people should go for the 1050 (or 1400) FME-P (note the P in the end) ... Tighter tolerances, better bearings and an ER-16 collet (I think it is ER-16, some sites claim ER-20, others ER-16). Oh and PWM speedcontrol on the FME-P DI models.
A fine tooth ( 6 tpi) blade on a band saw cuts aluminum like butter - I've cut up to 50 mm
you can cut aluminium with a lot of bandsaw blades
That old spindle motor seems the famous 775 dc motor
Marius, I saw that you made a change in the z-axis to a new machine, inserting a spindle mounting plate. Can you tell if the eccentric spacer is the same (size) used in the Spindle Carriage?
thank you
Marcus
Very good, I was tempted by this spindle too but couldn't really find it for a reasonable price. Having something which doesn't blow air down like a router helps the dust not throwing all over the place.
Great job...
Stepcraft sells an auto tool changer for kress for their own cnc. I don't know if the ATC will work with xcarve controller.
Jetzt noch seitliche Versteifungen an die Z achsen Platte um zu verhindern das sich das Teil wegbiegt dann ist die Stelle schonmal gut gelöst. Der Rest braucht dann auch noch ein paar großvolumige Verstärkungsprofile...
very gooooood.
OP! here's hoping you see this - Aluminum can be cut safely and quickly with little fuss on a table saw!
Hacksawing can be easy and fun. You just need high quality hacksaw and sharp blade, then put some grease or oil to blade. When sawing you need to find optimal grip and pressure to speed ratio. Then it goes like champ and you just have to be careful to stop in time :-)
Drilling "pilot holes" to metal before final hole increases accuracy.
hello
I have also build the Mattias's bandsaw, and I use to cut aluminium.
it cut 15mm aluminium.
very....very nice.....congratulations..... São Paulo - Capital - Brasil
Thanks for sharing. Lovely hack. Excuse my ignorance on CNCs, but does the extra mass of the new spindle affect the speed and accuracy of the cutters? Are the stepper motors and belts able to cope with the extra load?
+Jeff Harmed No, speed and accuracy are better since it has less vibration on higher feed rates. The stepper motors and belts have no problem with it either.
very good
Jigsaw + aluminium cutting blade = all your dreams come true.
was that a 100W spindle? holly 5 piece chicken McNugget meal that was small...
I like my 500w spindle it works well in wood and has variable speed of 0-10000 RPM and its not as noisy as routers. only problem is my cnc frame is as rigid as a bowl of frozen Jello.
5lbs force on the spindle tip and it deflects 3mm due to frame bending.
2,35 you can cating aluminium with table saw or bandsaw
Hi! Was für einen Fräser benutzt du denn in dem Video um das Holz zu fräsen?
they should hire you!
You sure have some lovely tools man. Jealous
one more question dit ju make ripple from the the Kress spider or does it be neutral with no problems, it´s fun and col with cnc!
how loud is it? Just like a regular router, right?
You can use ajig saw with half wood and metal blade with great success to cut aluminuim
use the x-carve to cut and add the holes in accurate position? just need to go slow
Nice !
But better blades, I recommend bahco. What were you using for threading as a holder?
+Marcin Zdunek th-cam.com/video/RRdr16loUSg/w-d-xo.html
Too prevent 'chatter' it helps to increase feedrate or increase cut size thereby increasing load on cutter!
moin marius, how do you control or set up rpm of kress 1050? do u use any relais or control over xcarve controller? thanks
at 5:06 why didn't you just flip the old bracket upside aligned with the two new holes to get access to the two drillable holes?
Make sure that dust doesn't get in the Motor , i see some ventilation holes
sehr gut Junge !!!
I'm not an expert so curious, would it be beneficial to add a second mounting/support bracket for the spindle, mounted near the top?
+Rob Lambert Probably, I noticed some issues with only one mount.
Hack saws are ok. Next time you want to cut aluminium try your drop saw. Clamp your aluminium between two thin pieces of timber and lubricate with WD40 as this will stop galling. Cut very slowly and let the blade find its own feed rate. Any carbide blade will suffice. The slower you cut, the better the edge. The timber will assist in arresting the chips as the hook and rake on most rip blades are not specifically suited to aluminium.
Hi Steve,
I don't want to burst your bubble, but you need to read the MSDS for the product. I won't bore you with the science, but the active compounds in WD40 do have lubricating properties. You are correct in that they also displace moisture. They also leave behind a residue that seals the surface from O2 etc.
Direct from the first page under product identifier:
Product Name: WD-40 Bulk Liquid Chemical Name: Mixture
Product Use: Lubricant, Penetrant, Drives Out Moisture, Removes and Protects Surfaces From Corrosion
The primary compound of Naphtha as refined in the common distillate kerosene was the lubricant I used as a machinist before some of the better cutting oils (water soluble) became readily available in the past 30 years.
+Steve Sherman - Yet it works. I guess the mechanical process of tribology occurs with smoke and mirrors...
what is system on which this motors are driven? can you give me links or videos of this system? it's better then linear motion, right?
Very nice modification and upgrade. Marius, since you are planning on reinforcing the rail system anyway, why not go with the stronger 611 router?
+MRrwmac The 611 is not stronger and not as accurate. Use Google to check that. And it's incredibly difficult/expensive to get in Europe (300€)
+Marius Hornberger Good to hear that! Sounds like the one you bought is going to be a great router for your CNC!
Falls du je vor haben solltest noch mal upzugraden dann würde ich mir über legen ob ich als Kunststoff nicht pa66 mit Glasfaser Anteil nehmen würde und als platte ein geschliffenes edelstahl blech so um die 6-8mm das kriegst du dann nahe zu perfekt Plan
(sind nur paar Mikrometer die da net Plan sind also für deine Anforderungen mehr als ausreichend)
You can cut aluminuim with woodworking tools a tip for the next time
#Q&A How old are you?
Great TH-camr by the way :-)
Wired holes in plastic never last long, use pressed in steel busses like tubtara!
how long can you run the die grinder? cause they get hot fast
Wood cutting circular saw blades chew through aluminum like butter. Throw that hack saw away! :P
