Trim/Crown Cutting Jig By Basswood

basswood

For big jobs, I make a cutting jig with a fence the height of the baseboard, and attach a curb to the table that holds the largest crown on that job (I make fillers that fit inside the curb to hold smaller crown "in position").

The jig allows me to cut base standing up, crown bedded (for upside-down and backwards cutting) and casing is cut flat in the same jig.

Any questions, comments, or tomatoes?

I like it. It is pretty much the same as what I do. It's surprising the number of guys who think it is a waste of time.

I make the same jig, it makes it very fast!

Takes 15-30 min and pays you back the same day.

I make mine out of 1/2" MDO (signboard). Here is a plan for a table/fence and supports out of 1 4x8' sheet:

Faster, Better, Easier... really we build these jigs because we are lazy.

Cole

You got that right!, I am with you.

Neo do you have a Delta? or are you just razzin' me?

neolitic

Yup, I like it, except at 65lbs
it should be listed as a
stationery power tool.

Thanks for the info! I do not do a tremendous amount of crown molding (trim carpenter usually does it) but I have had to do some in a pinch or on a small job. I will certainly be putting one together for the next one.

I also make something similar - you gave me a couple idea's to incorporate next time I through one together. Thanks.

Oops, I just noticed, in the 3rd
pic I can see you have the
"worm drive" version....
Mine is the cheaper twin laser.
You have more depth on a
left hand cut, right?
The lasers save a lot of glasses
on glasses off stuff for me though.

I bet you will like it. Since the aux. fence is zero clearance, it keeps small returns from being flung from the saw too.

Regards,

Bass

Always glad to help. Did you notice the scrap that I use to fill in between the two aux. tables, at the cut line?

basswood

Yep, the saw has great cutting capacity, good design. The saw did not sell as well as the DeWalt that it competed with, and with B&D owning both companies, they killed that model. I bought it as a discontinued model, cheap. I really like it though. Never had a laser on a saw, might be nice.

G'day,

Bass

Two questions: (and please forgive me for my ignorance)

1. How do you secure the wooden fence to the saw's fence?

2. If you cut larger crown and you want a crown stop/jig won't the 6 inch table top be too small? I noticed in your later post with the larger crown that it didn't appear that you used stops

I usually have to frankenstein stuff like that together out of whatever's laying around LOL

I use "Euro Mounting" screws. The fat shafts of these screws have great holding power, even in thin material, like the 1/2" MDO. My saws fences have holes for attaching aux. fences, if yours doesn't you can drill your own holes.

The crown pictured is 6-1/2" and the jig I made will work with crown up to 7-3/4" if the curb is moved out to the edge. This is the largest crown the Delta will cut bedded ("in position"--upside-down and backwards). I cut larger crown flat on my Hitachi 10" SCMS. I like to cut crown bedded with curb (though one pic shows a jig w/o a curb).

Thanks for taking the time to respond and for the photo. I have a Rigid SCMS and it does have the holes. Why don't you use your Hitachi SCMS all the time?

basswood

I use both saws on many of my jobs (see pic).

12" CMS's, like the Delta I use, have greater vertical cutting capacity than 12" sliders. This is most useful for cutting tall base, standing up, or cutting big crown "in position."

The trim carpenter I learned the trade from used a 15" Hitachi CMS.

http://www.toolbarn.com/product/hitachi/C15FB/

The 12" Delta I have has greater cutting capacity than the 15" Hitachi due to the innovative design (housing notched out behind the arbor, vertical motor, etc.--see photo). The Delta was designed by visiting jobsites and seeing how guys like me notched their housings and altered saws to get more capacity. The DeWalt 12" CMS is a close 2nd place in vertical capacity.

Of course, sliders have greater horizontal cutting capacity, but 10" sliders have about the same horizontal capacity as 12" sliders, and the 10" saws have less runout, less expensive blades, and are lighter saws.

This is why I use a combination of a 10" slider and a 12" dual-bevel CMS. The 10" slider goes to most every job, and the 12" Delta CMS goes to the tall base and big crown gigs. Best of both worlds.

The Delta is heavy, as mentioned, and spews dust in all directions, but it is the best for cutting big trim.
