Applying band sawn veneer

[noddy67]

I'm currently in a project that will require me to cover some mdf with a fairly thick (2mm or so) shop sawn veneer. I don't currently own a vacuum bag press. I think the panels will need to be larger than I think I can properly do with clamps. Does anyone have any experience of using hot hide glue for veneering thicker veneers like this and if so how would you go about doing it.

Many thanks

without you telling us what sort of sizes you are talking about its all about guessing. but I wouldn`t try doing it as you are stating. but as I`ve said you`re not giving much information out. How wide can a shop sawn veneer be one wonders

You can use lengths of wood (say 50 mm x 75 mm depending on size of veneering) which will extend across the width of your sheet, plane a 'very slight' curve on one edge, with one length on top and one underneath your sheet clamp both ends, the curved edges must be against your sheet and will ensure the cauls tighten from the centre out, they will eventually clamp the whole sheet when tight, with 250 mm or so spacing they will clamp any sheet up to your large 8 x 4 and negate the need for an expensive vacuuming setup.

I have hammer veneered band sawn veneers once. It worked out fine, may have been luck, may have been reasonably easy. Plenty of hot glue, nice warm place, a damp tea towel and an iron were the key points.

Had the same problem myself (think the veneer came out slightly thicker than yours) once doing some doors about 500mm square, think there was 4 sheets needed to cover a door and couldn't get a good join when doing it in one, ending up cutting the core that i was veneering onto into 4 equal widths and veneering those separately using clamps and boards to get good pressure. Then rejoined the 4 pieces like i was joining solid wood with a few biscuits to help. Bit of a long way round maybe but came out well.

I think hammer veneering veneers this thick will be a bit tricky. It will be difficult to get the heat from an iron through the veneer to liquify the glue. Also jointing the veneers will be problematic, you could joint them before laying but they may open again when laying. A bit more information about the job would be useful.
