Wood router duty cycle?

[Winston]

(...)

Careful with Amazon.com, Iggy.

TRS Recovery Services, Inc. (an extortion ring) has their hooks into them big time.

Lots of customers have suffered.

Most popular scam is for Amazon to mis-key a customer's bank account information. The transaction fails and is sold to TRS who makes the guiltless customer's life Hell until he or she pays TRS the amount of the transaction, plus an extortion fee. It gets worse from there.

The PC 690 routers (and most other brands) are also round bodied.

to R8, which isn't. It appears that it is exactly

there. If shipping is an issue, contact me off-line

Why don't you aks Steve to look for a spindle speeder? Very nice way to go.

Valid comments but I posted the information as an affordable 3x speeder was mentioned and IIRC Iggys mill has a 2.5krpm max spindle. It was put forward for consideration and any decision would then be at the discretion of the purchaser who has the choice of investigating the suitability of the kit further for themselves.

Personally I'd be tempted to try the router route as I already have a variable speed router which can also double as an electric die grinder. As the other router mentioned it has a cylindrical mounting boss simplifying the mounting aspect.

I wouldn't worry about it . That thing has a fan , and it'll be blowing chips out of it's own way . If you want something with more oomph , check out the Porter Cable line of 1/2" capacity routers - they go up to 2+HP and have a motor housing that's designed to be clamped in a base or fixture . Just make sure you don't get coolant up inside the motor , that can get colorful ...

We use Hitachi 3hp plunge routers. They often run 8 hours a day. They last

6 months and then I throw them away. We used to get them rebuilt but the cost curve says "pitch 'em!". Usually, the bearings go first but that's not all...everything just wears out! I have boxes and boxes of all the accoutrements that come with these that never get used. I just can't pitch them. I more than get my money out of them!

For your use, you're gold!

[Ignoramus12820]

Any idea what spindle runout you get on those while they are relatively new?

[Buerste]

Sorry, that was never a concern. We rout a 2" x 1/8" x 2-1/2" groove in Beech. It's not to critical, just good enough to index a long handle. What runout are you looking for?

[Ignoramus12820]

I am not sure, the less the better, 0.003-4 worst case, hopefully better. It would be OK for engraving, but not for precision work. I really do not know what I will be dealing with.

The Colt is the standard router for the CNC Shark sold by Rockler. It's one loud sucker but a good unit.

You can also get aftermarket collets for it for the purpose

it's fair to say quite a few people disagree with the fellow you spoke with.

I haven't tried those collets but I will say that the factory collet seems to get hot even with a short, non-taxing cut, in a way my normal routers never do under any circumstance. I don't know if this is the collet or the router, but it doesn't seem to hurt anything other than my fingertips if I don't give it a bit to cool down.

Without reading this whole thread I will throw in my 2 cents worth. I am more familiar with woodworking and routers than with metalworking. I have had routers in router tables that literally ran continuous for 8 to

10 hours per day, day in and day out, some carrying fairly heavy bits. They do have cooling fans, and in most router tables they are upside down so they must have fans to keep them from filling up with chips. Recommendations would be DeWalt, Porter Cable, Bosch, some of the older commercial Black and Decker units, or, if you can find one, a Stanley round top router. I prefer the Stanley because they are easy to mount, all metal, have a very strong bearing setup, and tend to be quieter than most because they turn slower (usually around 18,000 rpm instead of 25,000) and have such a strong bearing mount.

Here are some options:

've used the Proxxon die grinder and it worked pretty well for me in light use. The Kress router should be more robust. The Speeder may work for you as it is supposed to fit BP-type spindles, though you probably want more speed than it can give you.

I've got a speeder (belt driven only) which is straight shank. I got it from eBay some years ago. But I'm holding on to it for my Bridgeport.

Just letting you know that they exist -- and once you know what you are looking for (mine is in a wooden box with a sliding top, FWIW) your scrounging skills should turn one up.

The main thing when it is mounted is that you have to tell the CNC to not fully retract the spindle as it clamps to the OD of the quill.

Good Luck, DoN.

That one looks *nice*! I would like to see the top end of the anti-rotation strap to see how it is locked to the quill to determine how much of Z-axis travel would be swallowed up.

Enjoy, DoN.

[DoN. Nichols]

Well ... that may depend on how old it is. I have a Craftsman router from about 1976 which would clamp nicely to some channel (with clearance milled for the larger air intake at the top) which would probably do quite well for the task.

But more recent ones are certainly not as durable.

Enjoy, DoN.

i use a colt and i am doing back to back 8 hr runs in mahogany. Its got one hell of a duty cycle if you ask me.

[Leon]

You did how many 8 hour runs?

Most any decent brand tool will make up to several runs like that but can you do it 8/30 or 8/365?

But if it continues to do this, GREAT!

[clare]

Duty cycle depends on load.

If you have a 1/2 inch 3 HP router that draws 20 ampos at full load, and you run it at about 7 amps you can likely run it constantly without ever coming close to over-heating it. Duty cycle is generally pretty closely related to the ability of a device to shed excessive heat I know my 13 amp router gets plenty hot if worked hard for 15 minutes without reducing the load, yet stays comfortable to the touch if lightly loaded for the same period of time.. My lirrle Stanley (all metal trademaster? from the sixties) cools pretty well when rinning with the5/8 inch? plane trimming door edges.

[krw]

Yes, heat is always the enemy. Unless he's taking really small bites of the Mahogany (e.g. CNC light engraving), I'm surprised he can even

*hold* the Colt after eight hours.

[Martin Eastburn]

And remember to blow out the fan area and keep it clean - more air flow and less heat.

Going around corners might be a time to unload it cool it off and attack the next side. If slots ... between cuts.

Sometimes light turning cools faster than sitting off.
