GMC 180mm Power Planer

(Click on the image for the video - it links through to the specific post on Stu's Shed from which you can watch the video. I couldn't work out how to embed it directly into this post. It is too long to put on YouTube (although there is a cut-down version on there))

The GMC Full Width Power Planer.
Retailing at $199, this tool is an impressive development by GMC, and would be a very useful (and cheap) alternative in a workshop that didn't have a jointer, or for someone who needed one to be portable.

Despite the extensive Magnesium casting, it is still a heavy tool, which is an asset in this case. It has a huge infeed and outfeed area, giving the tool superb stability, both before and during a cut.

It also includes a carbon fibre casing, said to be 100% stronger than the traditional plastic casing. And importantly, it doesn't include an unnecessary laser!

I tested it on my connection (which is a 512kbps broadband, so isn't a fast broadband), and it took 42 minutes. There's going to be a much shorter version used by GMC on their YouTube channel, but that's really not the point of this review section.

Review was good. Downloaded it in the background so not sure how it took.

Looks impressive. I have even thought that MAYBE it could be mounted upside down as a jointer. Making a steel frame and using the 4 threaded holes for the fence as the mount. Rig up a fence and a blade guard. Extend the outfeed and an adjustable infeed table. Not too dissimilar to how Triton tables started. Only an idea as i have not seen one in real life

[damian]

I was thinking the same thing. Cut a hol in a table, mount some angle on the underside, screw some flat plate to the fence mounts and some horizontal bolts between the angle and plate.

The coda is funny love the fast forward and rattling the vacuum hose

Very good Stuart.

Looks like a good tool for what it's designed to do for a decent price. I'm struggling to find one in Brisbane to look at. No stores here seem to have them or even know about it.

FYI...this tool isn't unique as such. There's a serious industrial makita that planes 170mm with about the same sole length, but costs about $1000

Hitachi also make a 92mm plane with a longish sole, not as long as the GMC or the big makita, but longer than standard power planes.
http://www.justtools.com.au/prod685.htm

I don't know why long sole power planes aren't more popular. I've just started looking for one to prep slab timber before finish planning. I think a big power planer with a long sole would do the trick nicely. Stuff removing 5-10mm of aussie hardwood tabletop by hand


I was even considering replacing the standard soles of an 82mm makita plane with longer thick pieces of aluminium to get a proper joint set up going. Don't think there's any need now!!

Ordered one...should be able to pick it up saturday. Will see how it goes for what I want to do with it.

I picked up mine yesterday and have given it a good test trying to flatten slab table tops. I was not intending to use it as a make-do jointer or a beam planer. I only wanted to flatten large timber slab surfaces that are a bit warped and often chainsaw rough.

I won't go over what Stu already said as the tool does initially look impressive for the money...but...there are a key issues with the tool I bought that render it unsuitable for what I want to use it for (and I'd say even dangerous!)

The in-feed sole
1. Flimsy
2. As flat as the palm of my hand

Flimsy
The front or in-feed sole plate looks rigid, until you apply some pressure to it. It is way too flexible. It flexes all over the place and there's no way that this tool could be accurate with a front sole plate made out of rubber painted to look like metal.

As flat as the palm of my hand
Crap. Really crap! Did I say really crap yet? Set one side of the front and rear soles level (at a 0.5mm cut depth with is another issue). So the reference side is all level...slide your flat edge to the other side and you can drive a truck through the gap. I'd say it's easily a little over 1mm off from one side to the other. That's bad...really bad. Oh...there's no way to adjust this!

Soles line up on right hand side...

Not at all on the left hand side!

Durability
The tool looks durable, except for the soles. I reckon one drop with the tool falling on a corner of either sole and it'll break easily. That's just a guess though.

Dust/chip chute
Clogs very easily. Especially if planning across the grain which results in chunkier shavings. It seems that the plastic chip port has an internal lip with catches shavings and blocks it all up very quickly. The only solution is to go very, very slow. Much slower than the cutting action is capable of. I ended up taking it off and that solved the problem. No more blockages. But I shouldn't have to take it off. Simply a dodgy design.

Did try it hooked up to shop vac, but it made no difference. Clogged very regularly.

edit: this clogging happened on 1mm to 0.75mm cuts.

Blade locking mechanism
This part is scary. With the blades triple checked as being secured, after about 45 minuntes of use I noticed the planer seemed to me gouging more than usual on the left hand side (was gouging anyway caused by the sole issues). Inspect the blades and see that one of the blades has slipped out approximately 1mm. The securing bolt is still very tight, but the blade is coming out anyway. Not good. Not good at all. The whole way the blades are secured stuck me as poor from the beginning, and that's the way it turned out to be. Shameful design with potential to be dangerous.

Motor vents
Seem to become clogged very quickly. May add to motor prematurely burning out? Or maybe it won't make a difference.

Quality control
Initial blade set was hopelessly out of wack! I mean really out. No where near close to set properly. No instructions to adjusting it as the blade seat is supposed to be factory adjusted. Good in theory if the factory does it's job. Adjusting was pretty easy though if you've ever set blades on a jointer or thicknesser.

Add to that the poor infeed sole, and I'd say QA on this tool is poor. You might get lucky and buy a good one, or you might be unlucky and get a dud (like me)

Cutting performance
It cut really nice and smooth! Horribly inaccurate due to the sole issues, but quality of finish in each cut was good.

Stu's review
Stu...maybe your unit didn't have my issues? I can only judge the unit I received. I will be returning it to GMC for my money back. It's no where near not good enough and the blade starting to come loose has potential for serious danger. I'm very dissappointed as I had very high hopes for this tool.

[Stuart]

Sure sounds like your unit had a lot of issues, and none that I came across with my unit at all. So not sure what to put that down to - different batch? made on a different day? mine was an early production run? different unit (and therefore random QA)?

I'll certainly take another look at my unit when I have a chance, but as shown in the vid, it did what I was expecting of it without any particular problems (other than the dust clogging issue- perhaps I did remember to turn the vac on! - Irrespective, NOT turning it on guarantees a jamb!)

As put at the end of the comment, you can only judge the tool you receive. True for any end-user review obviously. You just hope that QA (or lack thereof) means that performance from unit to unit is consistent.

[bpj1968]

Sad to see a second differing view. QA is part of the problem GMC need to overcome. I have heaps of the blue gear and never had a problem with any of it, yet others have the same tools and nothing but trouble.

As far as I know GMC just buy their tools from any Chinese manufacturer don't actually make their own. They may even source the "same" tool from several different manufacturers

Have a look at
http://www.alibaba.com/catalogs/1417...c_Planers.html

On the first page there are 14 that look the same as my Ozito (Which has suprised me how well it has stood up to eth abuse I have given it.)

You may also recognise your thicknesser GMC, Hares and Forbes Carbatec, Ryobi.......

There are heaps of these manufacturer directories Madeinchina.com is another.

Gents, have any of you been able to source the 180mm replacement blades for the GMC Planer? I am very keen to locate a supplier. Thank you.

[chocwheaton]

Since I don't have mine any more I've never attempted to source replacement blades. Have you asked your local GMC retailer to order them? If they're not available that way it might get expensive. You might have to go to a specialised industrial cutter supplier.

Where are you located?

Cheers

Greg

[beeroll]

I asked the same question on Stu's Shed - he suggested Carbitool, who make a range of blades from 150mm upwards - there might well be something in their catalogue that fits. You'd need to measure the existing blade very carefully, of course.

CARB-I-TOOL

Chocweaton, there are no local GMC retailers any more, since the tools are no longer distributed in Australia, and I don't think any company is formally handling spares and warranty claims.

[vicc]

Hi Greg and Beeroll,

Thank you both for your responses. I recently purchased the machine on-line for a specific timber recycling project and like it so much I would like to find replacement blades if possible. I am in Perth and have been looking around without luck.

Although GMC are selling gear in the US and UK, the 180mm Planer does not appear to be a current model. I will drop into a UK GMC retailer on my holiday later this year in case I get lucky and they have some old stuff out the back.

Cheers guys.
