Re: RSG Gesso

Thanks for the tip on the sander.

The gesso was not a success. It just stayed sticky and scraped off easily. I must have got the recipe wrong by a good margin. I’ll try again....

Re: RSG Gesso

Thanks. I if I get the order I’ll probably be splashing out on a Mirka sander, I have my eyes on them for a while but £300 is a bit steep for normal sanding. I’m hoping the panels will be a regular order. If anyone’s interested they are made of the 25mm ally subframe from Lion and an outer of F9 fro...

Re: RSG Gesso

Thanks. It’s sticky at the moment so time for another coat. How long to dry hard?

Re: RSG Gesso

Fist coat done. How long to leave it between coats. It’s on a flat panel, it hasn’t gone on particularly smooth but I guess sanding will sort that?

Re: RSG Gesso

Ok, thanks, I’ve mixed 1part RSG to 12 part water? I see 800mlnof water so I recon that was 66 grams of RSG. So I should get just over a litre?

RSG Gesso

I’m making up some RSG gesso for the first time. I’ve soaked the RSG overnight and am going to warm it on a double boiler. The bit that’s eluding me is the ratio of RSG to whiting? This is for a painting surface not a frame if that makes a difference? Thanks

Re: octagonal frame

Cut on my mitre saw, and clamped up good and tight. There were a couple of very small gaps that needed some filler. Two coats of gesso. Acrylic spray. I’ve since waxed it which has improved the finish. Don’t over think it, it’s pretty straightforward, mainly sanding. 472D13E6-2DBE-4451-B66B-9D38843B...

octagonal frame

October was a a month of ‘firsts’ for me. Here’s one, my first octagonal frame. I do need to figure out the joining method, this was glued, clamped and cross pinned. I think biscuit joints would be better, particularly on a larger frame. Two coats of black gesso with a good sanding, black acrylic sp...

Looks a bit like Lions 30mm tray. L1883 or possible L1877

Using compo

I just got some compo in the post. It’s a lot harder than I imagined. How do you shape it and press it in to moulds?

Re: Compo frame decoration.

3D printing is an option but they are very slow if high detail is required. Cheap enough to purchase though. But a bit temperamental.

Re: Tabernacle Frame

After making the frame I gave it a good sanding with 120 grit. The frame was then painted with black gesso (My own mix). When dry another sanding, the black gesso turns grey when sanded so you can see all the bits you've missed. I masked off the sight edge edge and applied 'bole' ie red tile coloure...

Re: Compo frame decoration.

It depends on what I want to make. Nothing wrong with an alternative approach.

Re: Compo frame decoration.

Not quite, the ornament needs to be drawn in a 3D cad application. The best way I have found is to draw the pattern, scan it and trace over it in a cad package. Then export the file and an image and bring it into Photoshop, add shading and then convert it into a 3D file that the CNC software underst...

Re: Compo frame decoration.

A quick test cut on boxwood. I don’t have any compo yet To test them but I think it proves the concept. They will need a clean up. Wire wool I think and I need to work out depth of cut and profiles depth, not to mention a thousand other patterns that I need to choose from for 3D modelling. The file ...
