Is there a faster way to cut this? Took me forever to cut by hand with this blade.:banghead::banghead::banghead:

Dremel is your friend. Or a blade saw for the rough.

I use dental rotary tool. Dremel is not always good when working with thin plastic: min revs are too high. Dental thing is more flexible: from 0 to 30000+

Thanks for telling me. I already bought Dremel last night. :confused:

Well, I only used Dremel couple of times and maybe was not lucky or just too lazy :) I think it's just a matter of practice. Sorry for upsetting you, but I'm pretty sure you'll make it! :) just practice more!
P.s. and those dental tools are more expensive than Dremel :)

Chain drill it, then file to shape. Simples!

Its ok. I just cut for certain parts. If breaks down, I'll buy dental next.

Photo etch saw blade.

Drill some holes to start then saw as necessary down each side.

the dremel will allow you to get bits anywhere, and exchange easily if not working properly
did you get a variable speed? that's important feature IMO
some of the full 'kits' have extended flex lines and lots of bits included
ebay is great place for buying many bits cheaply

This is what I bought at Home Depot. I pay $45+Tax. I don't want to pay extra for fancy since it's over my budget.

A jewellers saw would be good for this.

You'd have to drill a small pilot hole to thread the thin blade through then attach it to the saw frame. They are cheap and really handy for model making. They take a while to get used to, so expect broken blades at first, but with practise you can cut through 1/4" steel with them!!!:smokin:

after being for up to 10 yrs an authorized dremel dealer and technical assistance repair center I can ensure u, for our kinda modelling such very good german drill is nearly absolutely unuseful.

the main problem, as said before, is just in the minimal speed they have, that just melts the plastic in a while,usually destroying also the drill or the saw u are using for the job.

Think is much better stuff (and a lot cheaper) the proxxon one:
http://www.proxxon.com/index.php

or, if u wanna go even cheaper (proxxon is already MUCH cheaper than dremel,btw) go for any ultra cheap chinese unknown brand. The ones sold in Lidl,works pretty good.
Dunno if in texas u have Lidl (german chain of big discount shops).nearly sure in any wallmart shop or similar u can find something suitable.

It must be stuff u can be able to stop with your own fingers at minimum speed.

Btw, my dremel comes perfect for small jobs on my car or on my boats.
absolutely nothing about modelling for me with this nice and precise perfectly working german drill....

That Dremel is just fine, but you have to know how to use it.
Plastic will easily melt, so don't let the tool stay in contact with the material for too long (like less than 2 seconds).
Here's how I'd do.
Using the cutting disk, I'd cut the inside of the marked box with several short actions, like a half of the length
on one side, then a half on other sides, then come back to the first one. I'd say, eight to twelve cutting actions
should be able to remove the unwanted area. Then I'd use a coarse nail file to enlarge the opening, making it closer to
the originally intended size, then finish with medium and fine nail files.

I have the same but cordless. You won't regret it.

Now keep an eye open for cheap accessories. Doesn't need to be dremel brand

Best way. Either way, don't use the sanding disk on plastic. Manual sanding is the best way

Well when I first started. I kinda cut all the way on one spot then go on next spot pretty much then I file it down.

Yeah that what I did after I cut it. I file it down and sand it to smooth it out.

+1 I also cut it small bit by bit, so to reduce melting flash, then sand smooth with emery board to flatten out
