Where do I get, and what do I need to get for porting these small 2 stroke engines?

What are you all using for porting the jugs?

Thanks,
Al

I have the hanging flex shaft tool that I got at Harbor Freight for $50.00.
I wouldn't want to go into business professionally porting saws with it but I've done work on 20 or more saws and it is still going strong.

Any chance of posting a pic of the bits you use?

I've got a cc specialties 182 hand piece on a chicago tools motor right now and 4 handpieces from srcarr. They're china pieces but he works on them and they're a lot smoother than the ones without work. I have a dremel flex shaft and now I wonder how I got by with it so long without the other ones.

http://ccspecialtytool.com. This is the place I got my stuff from. Nice people and good to deal with. http://www.foredom.net this is the company the makes most of what cc specialty sells. They are all kind of expensive but will last you along time. Just like any tools you usually get what you pay for. Just my 2 cents.

I have a Foredom flex shaft that I bought about 25 years ago for watch work.
I also bought a Chinese made flex shaft that works pretty good also.
I do not have a right angle head for it yet but that is next on my list.

MacmasterCarr has carbide bits too. I bought some carbide bits on Ebay http://www.ebay.com/itm/130396837057?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649. Very pleased with them. On a rt. angle don't bother with a Foredom 55 they are not strong enough for cyl. work go ahead and spend the money for http://www.ccspecialtytool.com/182a-mc-small-right-angle-handpiece-adapter.

don't think anyone has mentioned files yet. needle or riffler files are pretty handy and cheap. although, quality files can get pricey.

here are some ideas:

this sanding stick is nice for smoothing:

a crude but sometimes useful aid to do radii, that everyone already has are chain files. cut off the end, and use it to pull towards you.

hope it helps.

I have three Dremels but at the moment have misplaced two some where .You can get it done using long bits to get into the uper transfers but it's a chore verses a right angle high quality die grinder on a flex shaft .

I actually did a clam shell Poulan once with nothing but a couple files and sand paper just to see if I could do it .Pain in the butt but it worked .

On a Dremel if you use carbide to cut through the plating ,chrome or hard nickle after that a high speed steel cutter does just fine cutting aluminum .You can actually use bits designed for wood as long as they have a high enough helix not to plug up .

I use a variety of handpieces. As someone stated above I found a source for knock off #30 drill chuck style handpieces (far right two). All others I'm still trying to find a good alternative to the expensive foredom or cc handpieces.

This one shows more of the bits I use.

I did make this one the other day, it uses a cheap dental contra head and latch style 3/32" burrs. I was thinking of offering them for sale but I would also have to supply burrs for people whole can't grind down the shaft of an 1/8" burr to fit this head. It will be really good for smaller cylinders that the 182mc gets a little big for.

I recently found a cheap source for carbide. http://www.buckeyecarbide.com
