Hi Guys, Just about to order my first batch of Vslot and now thinking about also making sure I get the right tools to cut it. I am looking at getting a good 250mm sliding miter saw as this size saw should give me enough cut size to do a complicated compound cut in full size 8020. http://www.blackanddecker.co.uk/powertools/productdetails/catno/SMS500/ Would any one suggest other wise and if this is a good choice what sort of blade should I match to get the best results in Vslot?
That won't have any problem. I just recently cut some extrusion with my miter saw and the carbide tip blade I use for wood. It worked great but More teeth would have given a nicer finish. Another thing I would recommend is to use a good square to get the blade square. The slide rule on my saw was off by 2 degrees.
nice cut, I will make sure to get some high tooth count blades as well. Do you think hooking up coolant/mist would help as well?
I was guessing coolant would be over kill but I like going over board on projects..... I should also point out that I plan on making a few kits for local skateboard builders and plan to be cutting quite a bit of vslot over next few months. I am keen to make it as easy as I can while getting the best results so my ideas for coolant so far are: A friend suggested I add a wax feeder. He uses it for his duel saw but I wonder if the wax is acting as more of a lube between the blades than between the cut and blade. My other idea was to add a little drip feeder to drip some lube onto the blade or at the cut site. The simplest method I have come up with is to use a small air pump to lift coolant up a tube using a venturi effect setup. It is a trick used by indoor window gardeners to lift nutrient solution to a vertical garden. You get a constant dripping at the air outlet with just a small air pump, will that be enough to lift coolant... not sure... I got to go find an air pump later this week .... Any way in other news I did get a nice sliding compound saw second hand that just needs a good clean and a bit of fine tuning and should be perfect to get me started. Here is a good primer video I found that gives a overview on setting up a saw And then I think I will follow up with the tips on this page: http://www.wwgoa.com/set-up-your-miter-saw-for-perfect-cuts/ Hope this is helpful for others!
http://www.wikihow.com/Cut-Aluminum Quote The cutting speed used for wood is generally going to be too fast to safely cut aluminum. Using a 10 inch (25.4 cm) table saw, for example, you can reduce the blade to 7 1/4 inch (18.4 cm). This will subsequently slow your cutting speed. If it's not possible to alter blade sizes, consider purchasing equipment with a variable speed router. The equipment will be more expensive, but it will be easy and intuitive to lower the speed to something more appropriate to aluminum.
crud... I didn't think about tip speed when I picked up my 10inch drop saw for making kit set parts.... Poo! OK so any one put a small blade on a big drop saw? I had a look and it seems I will never get the blade to go low enough so this only leave the options of making a riser to lift the work to the saw or speed controller? Any one see any other options before I go looking into building a speed controller?
I use a 12" mitre saw with a 12" blade and it makes great cuts on V-Slot. Just take your time and use an aluminum cutting blade
I think this is correct take it slow on all new cuts until you understand the outcome. Practice on a end part first maybe. I am trying to build so i don't cut parts. This way i can use the parts on many prototypes. Re-use! Cannot afford the cost for every prototype i am planning.
In the video for the OX build Mark mentioned putting 'oil' on the ali when cutting it. DO NOT do this, please. Well, not a normal lubricating oil anyhow. They work too well at lubricating and hinder the cutting process. Cutting needs something that lubricates a bit then breaks down and allows cutting while carrying heat away. On aluminum I use one of 2 things, kerosene or beeswax. I do a lot of lathe work and a quick dab of kero makes for smooth easy cutting with relatively easy cleanup. On parts where I don't want any kero residue I use beeswax, just a quick rub on the surface to be cut. I also use this on my hacksaw, just rub some on the blade, similarly with HSS taps. An ordinary paraffin wax candle will also work. Try it and see..... On steel I use chicken fat saved from the roasting pan. Again just dab on with a brush before each cut. Yes, there are commercial cutting compounds that are much more amazing, but these thigns worked for my father, and work for me, and the savings can be spent on receivers and servos!
"On steel I use chicken fat saved from the roasting pan" this is a great tip. David. I will use beeswax however as i prefer this to meat products. Thanks loads for that tip. Great input.
After reading the through this thread, I ordered an Oshlun SBNF-100100 10-Inch 100 Tooth TCG Saw Blade with 5/8-Inch Arbor for Aluminum and Non Ferrous Metals for $54, including shipping. I will post the cutting results after I get the blade and have a chance to make a couple of cuts. Thanks everyone for the helpful info.
