Default I Burned up my Bosch 1617

Hello, new to the forum(today). Yesterday(Sat Aug 01 2009) I was making arched raised panel doors and smoked my router. It was installed in a bench-dog cast iron table attached to my Unisaw. Never had a problem until now, but it was my first go at arched doors, I was using red oak. Due to the unique table top, I had installed a probably too-smal small cutom box underneath with an attachment for my 4" DC system, and an adjustable air inlet to ensure airflow around the router. Normally, I use a second attachment on the fence, but due to the panel arch, I was free handing the panels with a big scary panel raiser. First use of that as well, I was paying 100% attention to the BSPR, and not much on everything else. The DC never complained or seemed to have changed pitch(the routing made incredible noise, however). I made one pass with all 16 doors using a 1" bearing, and was half way though again with a 5/8" bearing, to finish with the 1/2" eventually. The router abrupty stopped in mid cut. Odd, I thought, and looked at the switch, then breaker panel, eventually opening the access panel in the router box. It was completely packed solid with wood chips. Somehow, the air outlet got blocked(wide open throat at the bit coupled with no fence suction maybe?) apparently directed a whole lot more chips going into the box. Additionally, the cord in the box was partially obstructing the air outlet, and should have been secured better, and the DC was full, probably dropping air pressure. Anyway, I installed my PC690, and finished the doors, but now I have a plunge and fixed base and no Bosch motor. Can these be re-wired? Can I buy just the motor body? I should install a bigger 15 amp router if I'm going to keep doing these types of projects, but they'll burn up just as quick if insulated in wood chips that way. Would be nice to hace a reset switch for overheating. I didn't smell anything until the DC was turned off, then it was awful. If nothing else, this is to inform the community to peridically check things you normally might not be concerned with when performing new or unusual tasks. A larger box to contain the router may have helped, but I should have taken more breaks, and been less complacent about DC. Safety was and is paramount, but I killed a really nice router for no good reason.

Hi Woody:

Welcome to the forums!

If this my situation, I would consult a Bosch service centre to have an estimate at the cost to repair the unit. Also, find out from Bosch how much to buy a new motor unit. Once I had those two prices, I would decide whether to repair, replace or junk the Bosch pieces (motor unit and bases.)

Hi Woody:

On the other issue: There are points to consider when designing an adapter for the DC system.

The air flow through the router motor unit should be from a "dust-free" environment. This means that the dust-laden air from the table should NOT pass into the router motor unit.

The air flow should through the motor unit in the direction that the manufacturer intended. Trying to push air the other way defeats the protection built into the internal workings of the motor unit.

The air flow through the motor unit should NOT be restricted in any way. Forcing air into the motor unit's inlets is helpful, when done with moderation.

HTH,
Cassandra

Woody, are you saying the router's internal fan was unable to keep the chips from falling down into the air outlet? Is the router fan's air intake able to suck all the clean air it needs?

Mine runs a little cooler since I provided a duct for intake of clean air.

It's too bad Bosch didn't use a thermal switch or a thermal fuse. Brush type motors heat up easily.

Hello woody
Welcome to the forum. I wish that i could tell you, Yes have it rewired, It is usually to expensive to do it. If you like that router well, you may want to buy a new one, or a re manufactured one. I have had very good luck with re manufactured. I am told that many times, people will return them, or they are shipped back from a store as open box. What ever you do, i know that you will have some information that will protect the tools, Enjoy the forum, and please add where you are from on your profile. Thank you.

I'm curious, have you revisited the router to see if it would start once it cooled? Blow the sawdust out of it and give it a shot... maybe you'll get lucky and there will be a thermal overload built into the router.

Definitely worth a shot. The 1617 had a switch replacement, as well. You might get lucky and find that the switch is loaded with dust and isn't working. The brush holders are prone to build-up, too.

You can purchase anything from a new armature to an entire motor and housing. Good luck with the repair.

This seems like another endorsement for the "dual-chamber" motor enclosure, an enclosure for the DC and a separate space for the router's air supply.

Have you looked at the brushes yet ?
Its possible they have just glazed over or burnt up from the heat.
They usually go 1st don't they ?
MUCH cheaper fix if they did @ around $15.99 for the set.

The first step is to remove all the sawdust from the router. If it is really loaded this may require dis assembly. Dust can clog the router, block the brushes from making contact. After all the debris is removed you will be able to see if there is melt down damage. There is a good chance you can clean the router and re assemble it and it will work. If not then a rebuild is in order. One of my 1617 motors was a rebuild and it has been problem free. Since you mounted the router in the table how often have you removed it to clean it? As far as the dust collection box it should have 3 sides to channel the dust to the collection hose as close to the table as possible. This will draw the dust away from the motor better than any other situation and should your collector stop working because of a full bag you will have instant dust on the floor to show you.

At any rate do not "junk" the router bases. If you replace your router let me know and I (or someone) will buy the bases from you.
