Seeking suggestions for jigsaw tests

[Frank Pellow]

In the thread:

http://festoolownersgroup.com/festool-tool-reviews/festool-carvex-420-(both-mains-and-battery-powered)-comparisons/

I talk about tests that I have done using the following jigsaws:

-  Festool Carvex Battery powered

-  Festool Carvex Corded

-  Bosch JS572EB

-  Festool Trion

I plan to keep all four saws for the next month or so and would be happy to conduct and report upon additional tests.

 

[MrToolJunkie]

Frank,

Several suggestions:

1.  Any tests with perpendicular cuts would be great along with pics of a square.  

2. Also, how tight of a radius circle you can cut would be interesting using both circle cutter and without (I know you mentioned you do not have the accessory for the Bosch).  I have to make small circles often and do not always have a hole saw handy or the right size.

3. Did you notice any substantive difference in cut quality of the machines?  It sounded like they all cut pretty much the same but curious if there were any subtle differences using the same blade.  

4.  Did you do any test cuts using the guide rail 1. butting the edge of the tool against it and using as a straight edge and 2. using the guide rail stops for the Carvex and Trion?  I know the Bosch would not be able to use this, but would be interested to hear comments on straight and perpendicular using the guide rail in various cuts -- solid wood and plywood if possible.

5.  Did you do any compound bevel cuts -- flaring/beveling a wavy or curved table edge, for example?

Thanks!

Scot

Frank, please do more testing with the angled base.

I would like to see scribing on a line 1/4-1/2 inch into the stock 15 degree inward?

It does not seem possible in my mind without doing a few passes. It seems that if the scribe is going left to right or right to left with the base would be in the obtuse position, then it would be hanging off the stock.

If the base were in the acute or, better yet, reflex position then it would make contact with the piece.

You are correct!  If your cutting from above!

If you have the angle base in the open angle position  you will be sitting on the off cut piece which often can be 10mm or less so not alot to sit on.

If you have the angle base in the closed angle again you are right you can't scribe if you have to much off cut and not only that you can't turn so if you had to scribe inwards into the work piece and then come back out the back end hits the workpiece.

Only way to scribe is to scribe from underneath upside down.  Which I do anyway to avoid chipping and able to see the line better!  Saying that I don't find the festool angle base ideal upside down not alot of base to stop you tipping it when upside down.

Wow thanks...I thought about cutting from the other side of the stock but the back of the cabinet would always be in the way. I forgot to mention the turning part because rarely is the scribe line straight.

 

[MrToolJunkie]

Not sure I follow completely as it seems like you would cut on the cabinet just like they show in the videos, but at 15 or 20 degrees instead of 90.  Would half the base not be in full support with the cabinet side?  You might need to adjust it back and forth cutting top or bottom but it seems doable...maybe I am just confused.

What about angling the dimple base?  I saw in one of the demo videos Steve Bace said the dimples were in a line and that you could follow a line at an angle  - it is at 8.44 of the JLC Event video.  Not as accurate as the set angle, but maybe would work for scribing?

Interesting question.

I'm with Scot. I can't visualize why this wouldn't just work normally ?????

Link to the videos they do this scribe please???

 

[MrToolJunkie]

Here is a link to the one from Festool Connect.

Cheers! Ill look through the video later 15mins to long the be "glancing" at my phone with the Missus.  She won't be happy I'm fogging lol.

The angle base show and tell is at 4:40 and on for a bit. It isn't a demonstration (no cellulose was harmed) but it's clear that scribing is not supported with the angle base, at least the way the base is used here. When the base is set to an angle it wraps around the wood so it places the blade on the edge of the wood. You can't position the blade inboard to follow a scribe line even if you attempt to use the saw upside down.

The only way I can think of to scribe with the Carvex is to modify one of the snap-on flat bases by adding a 5 degree wedge to the whole bottom. Actually you need to do the mod to two of the same style base so you have the ability to cut in the opposite direction at the same angle.

Watched another video in the Carvex consolidated Q&A thread.
This video does briefly demonstrate the angle base in use cutting wood What I forgot is that the base can fold up as well as down. In the up position the base does not force the blade to the outside edge of the material. You can cut anywhere you want but when you are beveling less than 90 degrees the saw is supported only by the waste stock. And, if you are following a line close to the edge (as in scribing) there is almost no shoe engagement with the work since the middle of the shoe is a round edged hinge.

      Aaah OK, so the out board downward wing would prevent cutting in from the edge of the work piece.  Got it. That does seem to be a limitation on the Carvex. So we need an adjustable half base.  In any case I usually cut close to the line and finish with a sander. Putting the  back bevel on when sanding. I always seem to be working with wavy walls that need fine  tuning on the scribe.

Gotta agree with JMB . To me the angle base is trying to be  too clever for its own good . A simple angled base that you can flip either way would have worked so much better than the ' tricked' out fancy one. The more I looked at it the less I wanted it. Even upside down there just isn't enough of a platform to be stable. Happy with my Carvex but the angle base is a waste of money ( a lot of money ). IMHO.

Yes, but in American so Seth could understand it.
