Thread: rounding ends of 42x19

If it was me I wouldn't consider using the router to round over the end on the size material you have mentioned. I would make up a jig to use and clamp that to the table of a belt or disc sander, would be much safer.

Possible, but not easy.

You will need a small diameter rounding bit. If you allow for a small flat on the end it becomes a bit easier. I would prefer a bit with a bearing guide. If you are able, clamp the timbers together so that rather than doing a 42mm width, you are doing 84, 126 or more at a time. This allows the base of the router to have a bigger support area. Do one side of the timber and then flip over to do the other side. Expect that you may have some rejects until you get the hang of it and your settings are correct.

Good luck.

I think Handyjack & I may be looking at this in different ways. Using a small roundover bit would allow you to roundover the corners as in the second drawing. I looked at it that you wanted to round the end (42 mm) as in the first drawing, you would not be able to use a small roundover bit to do this.

Yeah, I suspect your right.

If a 'paddlepop stick' look is what you're after, I'd make up a template with the desired curve from ply, clamping it to the top - or bottom - of your timber and using a bit with a roller-bearing.

So long as the roller bearing keeps in contact with the template, you can't go wrong.

Thank you to all and first of yes i am rounding the 42 not the 19 and after reading everyones posts i drew up the design i wanted to be my template in office publisher then printed it onto heavy card cut it out and then transfered that to a piece of perspex clamped that between the piece i wanted to cut and a piece of scrap put that into the vice and it worked perfectly (well it would have) if the bearing bit i used was 19mm cut instead of 15mm.
But without everyones input i would not have been able to end up with the information needed to get this done ok off to bunnings now for a bigger bearing straight cut bit any particular brand i should buy or should avoid???

Cheer's and Thank You

If it's for a short run and a one-off job, it's not really important, but if you intend to start building a set of bits and/or are likely to make repeated use of this bit in the future, them get the best you can afford - quality always pays in the long term. CMT is a great brand, but there are a few others too. No doubt others will be along with their favourites soon.
