Well, got the Carvex 420 barrel grip model yesterday, came as a "Basic" kit, i.e no battery or charger, so a much cheaper package as I already have a few batteries and a charger from my drills. First off, a couple of things...
Barrel grip is quite large and boy its a heavy tool, and I am finding the on/off switches hard to reach whilst holding it. I have not got big hands so think someone with large hands it would suit better. I find I have to use my other hand or remove my hand and reposition it to find the switch to turn it on/off. I feel it feels unsafe doing this. I would like it to have trigger switch preferably, so may end up changing it over to the standard shape jigsaw and try that.
In reading the manual that comes with it if one can call it that

, it states to tighten the blade so there is just a slight bit of play either side of blade. This seems a bit of guess work and I found I tightened it up to what I thought was correct only to find the blade travels back and forth in the v guide. Seems alot of play there? So I ended up pushing the blade back hard against the stop and adjusting the guide width to the narrow width then letting the blade flop forward. Seems to work, but I don't get why the play in the first place. I guess its the pendulum motion so it must require that sloppyness movement? At least the blade didn't travel sideways and kept in the v guide ok. Not much marking on sides of blade so it must be fitted ok.
Tested out a few cuts in 17mm ply and 18mm mdf, seems fine to me, but I did notice halfway along a cut (about 300mm (-12 inches) it suddenly slowed and felt like it was jamming, it appeared the dust extraction wasn't doing much, and some chips were getting in the path of the cut. Once physically blown away it seemed to go fine again. I did set the vac on full and on manual start but still heaps of chips.
I got the circle cutter attachment and foot on special as well, so thought I'd try it out.
Tried the foot buy itself on a guide rail. Bit of a sloppy fit and there is no adjustment possible so had to push it hard against rail else it wandered a mm or so. Think I will put some tape inside the plastic foot to get a tighter fit if I use it with rail. Apart from that it did do a nice straight cut in the ply. No wandering off. Cuts pretty well 90.
Next I tried the circle cutter. So wanted to try this out.
What a great gizmoy! I clamped down a board, drilled the 4mm centre hole and drew the circle. Drilled a larger hole near the initial cut for blade to fit, then attached it to the jigsaw and proceeded to cut in the recommended anti-clockwise direction. Sweet as your nanna. I'm impressed, but the size of the hole is different to the size I was expecting. Unless I am doing something wrong, there were no detailed instructions on its use, so I may have set it up wrong. I'll make a few attempts and see. Maybe its something to factor in, blade width I'm guessing or simply didn't set the tape size right.
Next I just went crazy and wandered with the jigsaw all through some boards seeing how tight or straight I could do freehand, chip out was minimal on top once I installed the chip splinter guard, none underneath, . Of course I didn't read the manual (duh) and so inserted it and pushed it in a bit, turned the jigsaw on then pushed it all the way in flush with shoefront straight away. Manual states to leave it 3mm forward so one can use it again and re fit it for extended use. Never mind, it's on and works a.o.k, and I assume (but cannot find on website any reference to spare splinterguards) one can get spares of that cheaply enough.
Battery ran out half way through a cut, but I had played a bit with it a bit, so I'm hoping it has enough juice to do most DIY and general reno work I need it to without changing too often, but alot quicker drain that any drill I have, so that's something that took me by surprise, yes even though I read it here beforehand.
Lights are good and I get the upside down - off thing. Lights work fine for me as they are, so I doubt whether I will change their default settings.
Manual is a bit vague on settings in my opinion and I agree with Peter from England there. I've never used a pendulum jigsaw before so no idea what means what and what each setting does or how it effects things.
Tool itself seems quite tough, solid and blade change is sweet. I really like that - my other jigsaw has two screws to hold a blade in - B&D, circa 1756 or something ha ha, so a leap from that for me. The foot changing is easy too. Like that. But unless one changes the foot you can't have it set to any angle other than 90. Seems a shame to have to swap shoes to just do that.
All in all for a first evenings trial, I like it, apart from the hard to reach power switch, I may just be retiring my old faithful B&D jigsaw.
First job to trim some bargeboards up high on a ladder so I'm glad it's a battery model.
