Cool thats what I was initially looking at but there was two types

*8mm 7,000-28,000 rmp 750watt beast but its like 370mm long

*6mm 25,000 rmp 240watt at 280mm long was the one i was like being smaller and therefore better for the job easier to use etc cheaper is also a good thing.



Thanks for replys really helped!!!! https://www.nopistons.com/forums/pub...1047683894.gif

i don't know about over a foot, but it's right about there i think... sears version of the rotozip, right?



i bought the electric one because my compressor is too small and i've got ADD, so i can't just wait for it to fill back up, i gotta keep grindin' with something.



but problem will be solved very shortly--dad came over and wired up the 220 in the new shop with me, so i can now buy a decent compressor https://www.nopistons.com/forums/pub...IR#>/smile.png



220, 221...whatever it takes https://www.nopistons.com/forums/pub...R#>/tongue.png

No, not the rotor-zip thing.



An old fashioned die grinder like in WWII.



A nice piece, if a bit pricy.

Lynn ... do you use a oil when grinding? It saves a lot of bits especially when hitting the aluminum.

I use a block of bees wax. But oil works fine if a bit messy. Resist the urge to use WD-40 for this. Heated WD burns great.

Here is the link to the Harbor Fright grinder I have. Hard to beat that price.

ahhhhhhh... ok.

i'd hit it, but i should be covered once i get the new compressor.



wait--how loud is it? i like the rotozip because it doesn't amke much noise--i can work at night without bothering anyone https://www.nopistons.com/forums/pub...IR#>/smile.png

this has just become my favorite thread. i'm working on my exhausts now and their giving me a beating. i think i'm a very patient man, but my Dremel is getting bitch-slapped on the regular by the rotor housing and insert.

i donno how anyone could port with a dremel, unless you are just doing one motor. those things didnt last me more then 2 motors.

I'm with the Judge on this I have been using the Makita's for years no problems. http://www.mytoolstore.com/makita/mak08-08.html I've had the standard one for over 7years and has seen many an engine amongst other things and the bearing is finally giving in but is still useable. I now have the GD0800C which has a variable speed of 7,000-28,000 RPM. Also buy the correct bits for porting especially for the aluminum housings. They sell a bit specifically for aluminum and it makes life alot more easy. They sell cutting oils which work great I just use good old Castrol 20w50 works for me to keep my bits sharpe and last longer. Also a good idea is us a layout fluid like Dykem http://www.freemansupply.com/DykemBlueLayoutFlu.htm helps to see your port template and doesn't get affected by the oil and it's easy to remove with carb spray.
