I want to make my own base molding and found a bit i’m considering. Thing of it is my 2 hp router has not gotten here yet so I might have to use my Ryobi 1 1/2 hp router. Will the 1 1/2 hp be ok to use with this bit on poplar or would MDF be better. Material doesn’t matter because it will be painted..

IMHO you’re pushing it. The bit you reference appears to be approximately 2” in diameter, which will require you you slow the router speed to 16,000 rpm to 18,000 rpm, BUT my primary concern with that bit is that it’s 1/4” shank. I would not recommend a 1/4” shank bit for a 2” diameter, moulding trim bit! I would get a 1/2” diameter bit for the application you want.

Wonder why they would offer such a large diameter bit in 1/4” Doesn’t make sense. I will call the company and ask what diameter it is.

When routers first started becoming popular back in the late 60s, about the only size bits available were 1/4” shank. I remember I bought a 1-1/2 hp Stanley (later bought out by Bostch) with an additional 3/8” collet—the latest improvement. Problem was, I couldn’t find any 3/8” shank bits. Just a bit of trivia.

Multiple passes will be the key to doing this safely, not killing the cutting edge and giving you a good surface finish. Though poplar would probably be a bit more expensive, it won’t dull the cutting edge nearly as fast as MDF.

Would the 1.5 hp router be ok? I only ask because i’m under a time crunch. I have a gift card from sears coming (from reward points) and I will get a 2 hp router with that.

Thumbs down on the 1/4” bit.

In my experience, making your own molding with a router is one of those things that is a good idea in theory, but more difficult than it sounds in practice. Don’t get me wrong… it can be done. But feeding long pieces across a router table for multiple passes, while keeping the material in perfect horizontal and vertical alignment to the bit, ain’t all that easy.

Good point Charlie. I tend to do that from time to time. “Looks good on paper” hahaha. Kind of a shame because I can get poplar for $1.25 BF. That would have saved us a few bucks but yea even though i’d have a helper with the 8 foot lengths it would be awkward.

Some featherboards might also help to keep the board where it needs to be.

Charlie is right but I guess we all have to do it at least once .My suggestion to the OP is to save yourself set-up time and headache , go to HD and buy the ready made ones .

+10 for Charlie on this.

Multiple passes and/or multiple pieces will be more often frustrating than soothing. Even trying to just match two 48in pieces each (to be sized later) of door sticking and molding gave me headaches. Easy enough if you can cut all of your corner pieces from JUST ONE routed piece, but when trying to do so from multiples just isn’t in the cords, for me at least.

Back to the OP, get a 2 or 3hp router and 1/2in shank bits whenever possible. Just my 2-cents…

I wouldn’t use that bit either. You have 3/4” of cutter on each side of the bearing and the bearing itself is probably 1/2”. That’s 2” of bit rotating on a 1/4” shaft at 22,000 RPM. Plus, unless it’s being used in a table with the base plate removed, I believe the Ryobi is limited to bits 1 1/2” or less in diameter.

I’d go with the poplar. I’d only use MDF if I had VERY good dust collection.

I agree with charlie.
Advantage of doing your own baseboards is : Using two different bit profiles to come up with unique ” one of a kind profile”
Many years ago before we were able to go to big box stores and BUY all the moulding, we had to make our own. Routers just started being used. What I found in my experience was: IF you bought 100 lin feet of wood, you were only able to use 75%, rest was either chipping, poor quality, knots etc. “OF course MDF” eleiminates that…...somewhat. Cutting a LOT of MDF will also cause your bit to DULL faster than poplar. Lots of things to consider.
MY advice: If you are only needing a few feet …go for it. Take smaller cuts, feed it slow, DO NOT overheat the bit !
Asking questions and learning how to use that bit safely. You are going to appreciate feather boards and push sticks.
