order of operations

Postby Craig Salisbury » 13 Oct 2021, 16:18

here we go, quandaries R us!

So i knocked up this little shelf for my daughter, the back panel is 3mm ply which is backing for a mirror. my question is around how would you finish this? bearing in mind its going to be sprayed white. do I mask the glue areas and spray the components and then put them together? or glue it all up and mask the mirror then spray it?

My thoughts with the second option is that if the groove the mirror sits in is loose, I can mask it and then when done removed the masking and shim from the back to tighten the fit.

thoughts?

I'd make it so the mirror can be fitted last but it sounds like it might have to be fitted during glue up in which case you are going to have to mask the mirror.

Masking the glue areas seems to leave scope for little tell tale gaps after assembly unless you are very lucky/careful or both.

Not sure if I've helped :lol:

just kinda confirming what I saw thinking, i guess i could turn the groove into a rebate and then put the mirror in last like a picture frame. ill pop out and have another looksie at it.

That's definitely how I'd do it. It also makes it possible to replace a broken mirror, which may be important later.

Another option is to fix the mirror onto the back with a suitable adhesive or some of those double sided foam pads. That could be done after all other assembly and painting.
I used to think sticking mirrors on was a bodge job, until I belatedly realised that one on a bathroom cabinet I'd been using for years was done that way.

Bodge or no, it does give you a way to replace it if broken, or if the mirror fails through age, without rebuilding the whole thing.

didnt actually think of that, thats a decent approach providing the measurements are spot on. Grooves can hide those little mm's here and there :)

I decided to turn the groove into a rebate and will hold it in place with glazing points. it will hang on the wall on a french cleat. ill get some photos tomorrow before and after its first coat of primer.

So I turned the groove into a rebate, gave it a couple of coats of primer and topcoat and popped it on the wall with a french cleat. the finish came out lovely.

Could be a little big for the space its in....but meh

Careful someone doesn’t mistake that for a serving hatch.

Lovely job.

it did turn out nice, I haven't had that much experience with MDF, but this finsa stuff takes a finish really well and machines lovely. it definitely has its place in the *.

I like it. And the french cleat is my favorite way to hang stuff on a wall.
