220 volt chain mortiser for overseas

[canopy]

Making mortises in out of square hardwood using hand tools is very time consuming so I would like to get a chain mortiser. The trouble is I haven't found any on the market in Thailand and the voltage here is 220V, 50Hz. Can anyone suggest any possible sources for filling this need? I am thinking for instance something from China might be suitable if a source can be found. Thank you for any suggestions.

The Makita chain mortiser is available in both 120 and 240 volt versions.

But I guess you need to find a supplier in a 220-240 country that will ship it to you. Possibly Australia?

Or if you want to spend the money, you have europe too.

Mafell, protool, and hema make some, the protool and hema being the old holz-her chain morticer.

You can also find the ryobi chain morticer in 220/240v.

Ian, New sealand uses 110V?

Sure, Europe or Australia would be just fine. I'll accept any brand I can get. If I could just get a lead for a seller that will ship internationally that is the missing piece of the puzzle.

Actualy, axminster is dead cheap on the makita.

Most of the germans will ship overseas. It's just hard to make them speak english ;D

Nice, thanks. axminster in the UK has confirmed they can send the Makita 7104L for $1700 USD including shipping. Any other thoughts before I pull the trigger?

Dunno how good you are at chinese, but you could check ebay.com.HK, ebay.au, and gumtree. Check machines4u as well.

Nope, nominal 230volt.

Same as UK and Australia.

It is pretty cheap/ easy to get a step down transformer.  I don't think your voltage is as much an issue as the frequency.  Make sure whatever you get is rated for 220V/50Hz.

A 220V/60Hz motor will run 20% slower and heat up much quicker when run on 220V/50Hz.  This will likely shorten the life of the motor. http://www.usmotors.com/TechDocs/ProFacts/50Hz-Operation-60Hz.aspx


I would say Japan is your best bet for multi-voltage/multi-frequency motors as a portion of their grid is 50Hz and a portion is 60Hz.  Makita is based in Japan so they should be able to match your needs up.  Call their customer support number or email tech support and they should be able to give you a model number appropriate for your use.  Would hate to see you let the smoke out of a new mortiser. :(

Thehardway, as long as it's an universal motor (with brushes) they're dependent only on voltage. Not frequency iirc.

Satamax,

Good catch.  I was thinking induction motors which can give you a problem and are found in many other tools like table saws, planers, etc.

Yes, Universal (brush) motors will operate regardless of frequency unlike synchronous motors or brushless induction motors.  Many will still debate if this reduces motor life on basis of impedance shift, core flux saturation current draw at at startup and heat buildup etc. all a little over my head for today's discussion.

I found a previous thread on this topic:

Notice Oakwright claims to be using without issue.  I will take his word and yours it should be OK with proper voltage.

Thehardway.

I 'm not savvy enough bout electrics to comment about saturation of the cores etc. There's one thing i can tell you. Even induction motors can cope with weird frequencies. I've been playing with frequency inverters to control the speed of my machinery for years. I haven't seen any motor heat up.

I've has some on a 20" jointer planer combo machine for the feed, then same thing on my actual 25 planer. One on the spindle of my shaper. Then i have one on the bandsaw, but just used as a slow start. I've had one on a previous build of my cyclone, and bent the impeller by over-speeding it ;D

Another thing I've done, I couldn't find a 220v rotor for my delta sidekick saw, so I've chucked a 110v in it, and despite running faster, and way louder, it ran for few more months, before I swapped it for a diy band sawmill head, which I've sold now.

Just got a 82hp wound rotor motor for free today. I gonna transform that into a generator for my future bandsaw. ;D Yep, I'm no electrical engineer, but a complete nutter  :D
