Hi everyone.
I wanted to purchase two routers for my dovetail jig to make thru setups easier. Something simple and light.
My question is do the routers need to be variable speed to prevent burning? When routing hardwood for example with a single speed router you can often vary the feed rate to prevent burning, but in a dovetail jig you can’t that much. Would a single speeed router be okay say 80 % of the time? I have acess to variable speed routers when they would be needed but I was hoping to buy simple and cheaper. For example pc 690’s or DW 616’s.
Thanks for your time.

I use routers all the time..
My friend in the shop.. Some woods BURN whatever you do PERIOD! Whatever speed you use. As in Purple heart and Jatoba and someties Oak! ASH will burn ALOT!
I have NEVER found it a problem! I just get off most of the burns with fine grit sandpaper and glue it up!
I use a pair of 690's and have no problems with burning. Porter cable Omni-jig.

Hey thanks alot for the info. I hope you had a happy fourth.Webby
Dovetail cutters are small. If they're sharp, they cut cut burn free at 20+Krpm.
If your material is burning, it's from technique or sharpness not hi speed. As such: No need for variable speed, tho a nice feature nevertheless.
Note, templet work, ( the most demanding and comprehensive of routing procedures) is the end game in routing (not the starting point).
Routers
Thanks everyone for the good info. Routerman, I have checked your site many times for good info. I am amazed at the excellent quality of wokmanship in the router fence on the site.
Thanks for the clarifying info. I have five routers, 3 of which are vs. two are plunge one is dhandle, one is in the routertable and I have a cheapie laminate trimmer. I wanted a setup of simple two knob base routers just for the jig. I have been using my other ones, but they feel awkward and are heavy. For example the plunge base puts the knobs higher than I would like thusly the router wants to rock as I move it. A two knob base puts the control and the center of gravity and directional force as low as possible.
Thanks for the info, I am leaning toward a pair of dewalt 616's due to the wway the hight adjust is versus the PC 690'sWebby
My only comment.
Some woods will burn whatever bits or speed you use. If it burns on your saw it will probably do it also using a router.. Try cutting Purpleheart or some Jatoba without burning.. Almost impossible unless you cut a 'wee' oversize and then trim to size.. It may Still may burn. Yes my saw is aligned the best I know how to. Things come out to size at both ends and at 90 degrees or whatever I'm cutting at. Is all I can say!
Webby,
I only dial down the speed on my routers when using a bit over, say, 1-1/2" diameter. Burning is often caused by too slow a feed rate or a dull or pitch-covered cutter.
