BillyJack Posted November 21, 2019 Report Posted November 21, 2019 (edited) There was a guy on Woodnet many many years ago who machined a bowl cutting jig that mounted to the router which mounted onto the project. It rotated to form a change/bowl cutout... Anybody familiar with what I'm talking about? Edited November 21, 2019 by BillyJack Quote
BillyJack Posted November 21, 2019 Author Report Posted November 21, 2019 Similiar to this but with a router mounted to the top that pivoted... Quote
Gerald Posted November 21, 2019 Report Posted November 21, 2019 I would also add he must have been using a special bit also. They are used for trays. Something like THIS Quote
BillyJack Posted November 21, 2019 Author Report Posted November 21, 2019 The router jig used a straight bit. I remember how it was made guess I'll make one. Got to do something with all those routers sometime.... Quote
BillyJack Posted November 21, 2019 Author Report Posted November 21, 2019 If the swivel base turns it ,then the rocking base motion lets it cut the radius out. Kind of like chair base routing....just spin till all radius are cut out... DuckSoup 1 Quote
BillyJack Posted November 21, 2019 Author Report Posted November 21, 2019 This is similar but from metal... Quote

BillyJack Posted November 21, 2019 Author Report Posted November 21, 2019 It's similiar but not the same. I think that guys name was mezalof or something. I can't get on Woodnet to research it.. Quote

BillyJack Posted December 22, 2019 Author Report Posted December 22, 2019 (edited) The jig would be useful for many things lew but the one I'm looking for is really small and can be used on large projects. Thx... The Dewalt 625 has centering slots on each side I'm thinking I can mount metal pins in and center pivot it. Edited December 22, 2019 by BillyJack Quote
DRAGON1 Posted December 23, 2019 Report Posted December 23, 2019 That's going to be one really long bit to clear the baseplate of the router and get deep enough for the bowl. Might I suggest looking at long straight cut or long cove bits to give you an idea of the range of depth you're gonna need to do that bowl. Quote

Gerald Posted December 23, 2019 Report Posted December 23, 2019 Bowl cutting router bits are not intended to go deep. It is not like turning a bowl on a lathe and a longer bit could get very dangerous as there would be too much flex. Now if you want deep look at the Arbortec 2 inch . It can get a little over 3 inches but not in a router . Artie 1 Quote
Gene Howe Posted December 23, 2019 Report Posted December 23, 2019 I've made several oak, maple and, walnut candy dishes using a 1/2" shank, bearinged bowl bit in a 4" extension. The cavities were first hogged out with a 2" Forstner. Used a 3 1/14 hp plunge router. My deepest cut was 3" but, it felt safe enough for another inch. Quote
BillyJack Posted December 23, 2019 Author Report Posted December 23, 2019 (edited) Straight bits come I believe 3" long. It looks like a bowl but is actually just a key or change bowl. Doesn't have to be 3" deep. Shallow and wide would be fine... I think the pivot probem isn't too complicated but the turning is. Either way the router will have to be mounted to a turntable. .. It's too bad the guy from Woodnet Isn't around to look at the jig. I can't find a picture of it either... Edited December 23, 2019 by BillyJack Quote
Gene Howe Posted December 23, 2019 Report Posted December 23, 2019 My candy dishes had straight sides. For sloped sides, you'd sure need a cradle like you posted. But, I'm not understanding why the router needs a turn table??? I'm not good at envisioning stuff. Quote
BillyJack Posted December 23, 2019 Author Report Posted December 23, 2019 Spin the cradle ,not the wood... otherwise it would just make a slot.. Quote
HandyDan Posted December 23, 2019 Report Posted December 23, 2019 I was thinking about the router as a pendulum but that would limit the depth to circumference ratio. Quote

It is... at this point he router can only make a certain size rout. A larger rotating base and a longer base will make a larger bowl. 3-4 inch radius is all I'm after. Otherwise a penilum as suggested in the picture above would be needed... Quote
