Aluminum spindle mounts for Makita RT0701c

Post by criznach » Tue Mar 11, 2014 6:30 am

Based on a design that I initially cut from cutting board, but they broke easily. These are cut from 1/2 inch aluminum using a 1/8" single flute spiral end mill from Inventables. I moved the clamping bolt to the side, and intend to drill and tap the flat on the front to accept a pen and/or drag knife holder. Step down was .2mm per pass, feed rate of 400mm/min. Makita's speed was set to about 3-1/3 on the dial, which goes up to 6. I used some silicone spray initially, but I ran out and cut most of the job dry, periodically vacuuming chips out of the cut.

Very nice!
What is the max speed on your Makita?
Google says: RT0701C has a powerful 1-1/4 HP (maximum horsepower) motor with a variable speed control dial (10,000-30,000 RPM)
So 3 +1/3 is 25000 RPMs then?

@Criznach - The lighting makes it look like wood! Are you sure it is Aluminium?? :D

I'd guess more like 20000 no load.

Does anyone else have an optical tachometer? Mines cheap and rubbish, but I need to get one that works.

No, it's not very stock anymore. I added the Makita RT0701c trim router, 1000mm Y axis with reinforcements, homing switches, and extra v-wheels on the Z. I think you could probably do this with a stock shapeoko if you were patient and did some testing first. They take 2-1/2 hours each to cut, so you want to have everything dialed in. I'd recommend cutting them out of plastic first, install them and the router, then use that setup to cut the metal versions.

Here are the drilled, tapped, and installed mounts. I'm very happy with the results. The tapped holes on the front can be used for a pen or drag knife holder (eventually).

John The Noob here...I've just completed my build, purchased the makita, and deciding on a mount. Can you post another picture of your mount, this one from the side? I am interested to see how high you've placed it on the motor mount. I am concerned with overhead clearance between the top of the makita and the stepper motor mount plate.

Thanks and congrats on a nice design. Great idea to add the forward mount for a pen.

The mounts alone did restrict the z clearance. I've attached the only other pics I have handy, but I could take some more if you like. I solved the problem by creating some custom z motor mount plates that do not interfere with the router. They are shown in the second picture. I'm getting my DXF files organized to share, but am also going to make some of these parts for sale if you'd rather not make them.

Do you think you're Z-axis plate would work with the Acme screw upgrade also?

I could test it for you ;-)
