Hi


A couple of weeks ago I got a Craftsman Industrial Laminate Trimmer model 315.275120 for free. It got dropped and then was turned on and did nothing but smoke, thats why I got it for free. I took it home and took it apart and found that the magnet field inside was broken, I ordered a new one and after putting it back together and turning it on, it sparks REALLY badly. I looked online to see how to check the armature to see if it had gotten damaged but it checks out just fine, I then ordered new brushes because the old ones were in bad shape. I got the replacements in yesterday and after installing them I tried it out and for a moment they seemed to work but then the sparks started back up. At this point I'm not sure what to check next, any help would be greatly appreciated.

time to count your losses and toss that bad boy
might need a new brush holder or the shaft is out of alignment

Hi


Unfortunately it came to a smoldering halt earlier today, that's $70 in parts down the drain. Would a Porter Cable trimmer be a better option?

I have no experience with the Porter-Cable trim router. The "modern" compact routers are very nice, combining a lot of power in a small, comfortable package. Those compact routers run at 31,000 RPM. That's fast. Really fast. Some routers have a speed adjustment, others do not. I have a Makita RT0701CX7 Compact Router kit, which lets you adjust the speed.

-> The potential problem is that a router can burn your wood at 31,000 RPM. When you lower the speed, the burning doesn't happen.
-> Having learned the lesson with my Makita router about speed and burning, I would recommend a compact router with a speed adjustment.

Porter-Cable makes different compact routers with fixed speed (31,000 RPM) and adjustable speeds. One thing that I noticed about the Porter-Cable is that it has a light. My Makita does not.

My Makita has razor sharp edges on its machined metal sub-base. It isn't really a problem as long as you handle it with care when the plastic base plate is removed, just like handling sharp blades. It bit me once, and I learned a good lesson. I do not know whether sharp edges are common to all compact routers. It may be.

I hope this helps.

Hi


The Craftsman is now just spare parts, on the bright side I picked up a lightly used Makita RT0701CX3 kit for $100.

Hi


Oddball question, is it possible the voltage rectifier went bad in the Craftsman?

Most of my corded shop tools are Porter Cable, routers, sanders, circular saws. However Bosch is my choice when it comes to my laminate/profile router and my jig saw.
