Is there such a beast? Or what would be the best way to put a 1/4 roundover on a 4" thick timber?

The best way is via template and a hand plane. That is also a case where the power hand planes can be handy. :)

I was thinking a belt sander. Also need to mention that this is on end grain. I told my client that this was the difficult part of the job (why my bid was expensive), and she told me that someone said they could route it easily for $90. I want to see that router.

If they can route it easily for $90, it is well worth it. I would like to see the router. You could cut the bulk of it off with a tablesaw or skill saw, but it would be a lot of handwork.

If that router exists then do it, but other than that bandsaw/jigsaw then belt sander then handwork. Biggest bit I have is 1 1/2" Rad

To clarify things a bit. I was asked to bid on making this:

img028.jpg


Basically the 4" x 12" upright supports with rounded over tops and the internal frame which is laminated 2 x 4 stock covered with copper (I planned to use rolled flashing). The sign panels will be made by the sign company I am biddding it to. I also have to install the piece with 2' burial in concrete. I gave a price of $1300 with materials being around $400 and the rest is my labor and material mark-up.
I was told that my bid is probably too high, and I explained the difficulties in cutting the roundovers on the ends of the 4" x 12" cedar beams. I was then told that they had got a price from the lumber company who was to supply the cedar to route the ends for $90. Can that be done with a router or even a shaper, or did my potential client just not explain the situation right.
And what do y'all think of my pricing, I didn't care if I got the job, but I like to make money. Plus I returned my pricing in the same day that it was requested...they needed to know right away :roll:

Dave,

Based on your drawing, the tops look like a fingernail profile which can be cut on the bandsaw. Same kind of cut that is on a workbench foot. Least that is how it appears to me.

I would agree with you Mike, if you have a BS with a 12" cut. I had considered ripping the piece in half and cutting the profile on my BS (6") But I am still confused by the offer to route that profile that my client got.

That's got to be one heckofva bit if it will round over that big. Must have a 2" shaft. lol There is a millwork place here in Wilson but I would bet they don't have anything that will do that kind of cut.

Me thinks the client is trying to get a price reduction.

Just my two centavos

Me thinks that the client didn't explain what they wanted very well. I told her to call back and confirm that they could do what they offered. I reckon we'll find out tomorrow.

Dave,

They would have to use a shaper to do that. There ain't no way a router could do that. I have seen, and used some VERY large shaper and moulding cutters in my time. I was younger and stupid.

Here is one manufacter I know that makes some large industrial shaper cutters.

Check out the radius on the cutter at the bottom of the list:

Who was the supplier that was going to do that for them? Stock Building Supply; I know that when it was Carolina Building Supply, they did millwork, and would have the tooling to do that.

A good CNC router could probably make that cut. Tom, over at Tarheel Filing probably could do it. Routing roundover across the width (long deminsion) could be done with router with an extended base plate and a couple of radiused pieces of MDF or ply attached to sides. Corners would have to be shaped by hand. Check with Rodey's Signs in Apex as they probably could do all the work for you, as your subcontractor.

Captial City Lumber made the "routing" offer. The largest radius I see on that link that you posted is 2". This needs to be 3¾" radius.
I just don't think that it can be done with a single bit and someone is getting sunshine blown up their backside.

Dave,

How about a template and a top bearing bit like the 50-126. It looks like this one:
B00004T7J5.01._AA280_SCLZZZZZZZ_.jpg

But it's 2" diameter and 2" carbide height. Not for the feint of heart but it would work.

Circular saw, and a PC-690 will do it, using a 1/2 bit. Using radiused guides and extended base to span guides. Probably 2-3 hours, with most of time spent making guides and extended base. A little scraping/ sanding and you are done.

Well, it is a good possibility that I may get the job after all. So I will have to consider everyone's suggestions and come up with the best way to "get r done" Thanks for all the advice :icon_thum

Does anyone you know have a porta-band (not sure they make one with a 12" capacity, tho):lol:

Dave -

I have a 1-1/8" radius roundover bit. I know its not the full size you were looking for but it is a BIG roundover and may give you a radius that will work on your piece.
