Boringhead
« on: May 22, 2013, 06:00:06 PM »
Hi all.
I made my self a new boringhead for the Aciera F3.
The F3 have not so much "daylight" betwin the table and vert. head so I made the boringhead with 15mm(largest collet I have) stright tang. but first I had to make small 45* dovetailcutter. I was a little bit worried if it would hold up but it did just fine, even the boringhead was made out of som mystery SS steel. I scaled down the plans from Mr Ishimura( Nifty Amigo)
Here are some pics. First from making the cutter.

And here are the "Female" finished :LittleDevil:

And here's the two together :naughty:

And here is it finished.


I tryed it last evening with a homemade cutter and it working just works great  :whoohoo:

Regards
CS

Very well done CS  :ThumbsUp:

Two questions if you don't mind...
Does it have a gib strip between the locking screws and the dovetail ? - I can't see one, and if the screws are acting directly on the dovetail, they are going to damage it - unless you overcame that problem in some other way...

What thread pitch did you use for the leadscrew ? - I'm assuming it's metric as you're from Europe.

Kind regards, Arnold
Building an engine takes Patience, Planning, Preparation and Machining.
Procrastination is nearly the same, but it precludes machining.
Thus, an engine will only be built once the procrastination stops and the machining begins!

Hi again.
Vince: your welcome ;)
Arold: I use inserts in front of the bolts filed to 45 * the two outer acting as "gibs* and the centerfor locking.
I made the adjustingbolt with M10x1threads. But if I have to do it over I would have used M 10x0.5 pitch.
Here is a better pics. that's show how small it is.


Best...

Very slick CS, I like it. A perfect size for those smaller holes. Arnold already made the inquiries that I had so I'll just say "great job"  :ThumbsUp:

That last picture really shows how small it is CS. Very nicely done and i suspect it will see a lot of use also.
