Scott Grove was on the town and stopped in for just a few hours to point out us the right way to do a radial veneer sample in addition to train us a little bit of the fundamentals of veneering.
Thanks to Actually Wooden for offering the veneer for this demo: https://www.certainlywood.com/index.php
Earlier than getting began, Scott goes by way of the pack of veneer to examine and quantity every sheet. He’s on the lookout for any sheets the place the knife might have skipped leading to one sheet being too skinny and one of many adjoining sheets being too thick.
To find out the reduce location of the radial wedges, Scott makes use of mirrors angled at 45 levels to preview the sample. The mirrors could be moved and pivoted to regulate the sample. As soon as the place is about, the wedge form is marked out.
Since wooden is natural, it’s widespread for the grain to shift between sheets. Scott goes by way of and aligns the grain so the purpose of the wedges will probably be uniform.
With the sheets held collectively, Scott makes the primary reduce with a knife.
To chop the wedges completely, a straight edge is caught all the way down to a base to behave as a fence and a wedge template is used to information the knife to make the wedge reduce. The template is reduce to be a bit over 45 levels.
If the wedges are organized sequentially, the primary and final seam probably wont match up very nicely.
To assist stop having one drastically totally different seam, the items are combined up a bit. It will distribute the error so no seam will probably be good however there additionally gained’t be one seam that’s drastically totally different than the others.
The wedges are taped collectively in two components which permits for some adjustment earlier than assembling all the radial veneer. Because the wedges are reduce to somewhat over 45 levels every, the ensuing semicircle is somewhat better than 180 levels. The sting which will probably be joined collectively could be trimmed to be straight with a knife and straight edge. Being somewhat over 180 levels and trimming is a greater place to be in than being beneath 180 levels and having a spot.
The 2 trimmed halves could be joined along with masking tape and the radial veneer is prepared for urgent.
To press the veneer, Scott is utilizing a vacuum bag which makes use of a vacuum pump to tug the air from the bag. The result’s atmospheric clamping that evenly applies stress to the veneer stack. Scott makes use of Titebond’s Cold Press Veneer glue for this. It has an extended open time than common yellow glue and is much less viscous so it may be rolled on simpler.
We pulled the veneered pattern out of the press and right here’s the end result! Some veneer and a little bit of knife work outcomes on this fairly unbelievable sample.
That was so far as Scott and I obtained that day so I’ll ending up the instance from right here. Very first thing is to chop the sphere right into a circle. I’m utilizing Scott’s Ultimate Router Base as a trammel to chop the circle. I make a roughing go, stepping by way of the thickness and as soon as I’m all over, I’ll bump the trammel in a hair and make a clear up go in a single go.
Lets run by way of the method of including a stable wooden edge to this factor. Utilizing a ½” diameter pattern bit I’ll route across the radial veneer desk high or no matter this is likely to be to create a template that’s ½” larger. A very powerful factor right here is to maintain the router bit bearing pressed towards the workpiece. As I’m going round, I’m pulling on the router base deal with to maintain the bit tight to the workpiece. The outer perimeter is what we’re after so if the bit pulls away, we’ll gouge the reference space of our template. I’ll simply go round as soon as so I don’t danger the bit wandering on a number of passes. The remaining waste could be reduce away with a jig noticed and flush trimmed.
With the template prepared, I can begin engaged on the edging inventory. It will likely be made up of segments. I’m going with a 6 section ring simply to shake issues up a bit because the radial veneer is 8 segments. I’ll assemble the ring in two halves so I’ll reduce some clamping areas into the waste close to the nook and get these assembled. As soon as the glue units, the segments could be screwed to the template.
This 1” disc comes with the router base and makes it simple to attract the reduce path of the router. This enables us to attract a reduce line and take away the majority of the waste first earlier than routing.
The half rings are trimmed and reattached to the template. And now we are able to route them to completely match the veneer factor.
It is a ½” router bit and a 1.5” information bushing. The offset between the bushing and the sting of the router bit is ½” – Precisely how a lot larger our template is than the veneered circle.
All now we have to do now’s route across the template with the bushing using alongside the template. As soon as that is reduce, the banding could be glued to the veneered area.
The glue is about up so I’ll get this factor out of the clamps and reduce the banding to last measurement. I’m going for a ½” broad band so I’ll use a compass to roughly mark the width and trim it on the bandsaw.
Then it’s again to the trammel utilizing the identical middle level within the veneer to trim the banding to last measurement. I’ll once more do a roughing go in a pair steps after which a clear up go with the trammel radius lowered only a bit.
