Starting with a blank hot glued to a piece of 26mm MDF which was in turn screwed to a face plate, i turned a small hollow, the fastest speed i got to was 365 RPM due to the amount the blank was out of center. I had toyed with the idea of screwing something to the MDF over hang to counter weight the piece but as nothing was to hand i ploughed on slowly.
I had hoped to re-use the MDF but being worried about the stability of the blank i over did it with the hot glue & ended up tearing the MDF to bits getting the blank off. On a plus side it showed how well the glue holds.
With a new piece of MDF screwed to the face plate, the blank was reversed. I`d chamfered the edge of the MDF with a hand plane as i was going to try a different approach with the hot glue.
With the blank centered on the MDF i filled the chamfer with hot glue, it was then time to mount it on the lathe.
Happy that the blank was holding, i turned the bottom of the bowl including a foot. Not only did i want the foot for holding purposes, but as this is only going to be a decorative piece, i like to see the bowl raised as it adds lightness to what is quite a big bowl.
This time the bowl was much easier to remove, just running a Stanley knife through the glue joint.
With the bowl held in a chuck via the foot, the face was trued up & sanded, once happy with the surface prep, the bowl was sprayed with a coat of acrylic sanding sealed & then acrylic lacquer.
This will be de-nibed & sprayed a couple more times before being returned to the lathe & cutting back with burnishing cream.
I think this is great. Nice post as well with the step by step.
ReplyDeleteThanks Mr Turner for going to the trouble of posting this, most interesting.
ReplyDeleteI particularly like the top-tip about the hot glue.
