Porting Tools

Up to now most of what I’ve done is trouble shoot and repair on saws. Lots of Stihl and Husqvarna mostly. Some Dolmar and Makita.
I have done some minor port work, widening and lowering intakes. That’s with a dremel in hand. And muffler mods.
I’d like to step it up.
Having said that, I don’t see myself getting a lathe to cut squish and deck it.
And I don’t see room for a compressor large enough to supply high end die grinders.

Now that I’ve boxed it in,,

What would you suggest?

I was looking at a couple of these grinders

Porting and polishing kits for 2 stroke & 4 stroke engines

Over?

 

I was in your spot a couple years ago. For doing the port work, I got one of these: Flexible Shaft Grinder and Carver (harborfreight.com) (any foredom handpiece works with it)

Here is a good option for a RA tool for doing upper transfers: Angled Rotary Porting Handpiece Kit – Lucky Dog Manufacturing (luckydogmfg.com) (unfortunately they are sold out right now)

If you get into the porting and need someone to do squish band & cylinder base cuts, I have a lathe setup for doing that & could help you out.

 

I buy most of my porting tools ( at least the carbide burrs and such ) from Goodson , 99% of what I do is automotive related but you might want to browse their sight and see what they have for your application.

 

Those kits from CC are good stuff. A foredom flex shaft with the right angle head and some good burrs and you are ready to go.

 

Slowly following up.
I looked hard at CC kit and the Foredom. Even sold some saws to fund it.
Chatting with FWC member I decided to start with HF. With tax, and coupon, just shy of $39.
Have a Foredom hand piece on the was as well as some burs from Amazon

 

Let us know what you think after using it for a while. Maybe could use one for a backup.

 

This is what I use in addition to some CC specialty handpieces.

 

The HF unit says 5/32 chuck...can ir still use 1/8 bits?

 

yes sir

 

I think I'm going the harbor freight route as well. I only dabble and have gotten by with a Souix brand air pencil grinder. I can get a 90° version and keep rolling in with air but the idea of a pedal for much more speed control is very appealing.

 

I'm trying to find an affordable right angle tool.

 

I did use the HF unit to clean out some transfer and it worked great for that. Way better than a home made mandrel on the end of an 18v drill.

 

Drill does not have the RPM for that for what I do.
I do a lot of cylinder head work for race cars and nothing works as good as the good ole' air die grinder.

 

I would only use for hogging and rough out on larger ports, but this thing is a fire breathing dragon. It will remove a lot of material in a hurry.
