glass bed
Hi guys,
so I have some borosilicate glass, the makersome shim and kapton tape...
The problem is the glass I have is over sized,what are some of the ways I could clamp it?
Could I use some form of double sided tape to adhere it? if not what is a good tape to adhere these substrates? VHB Tape? Carpet Tape? Selllo Tape?
could I use the sellotape between the buildtak and the glass or should I take the buildtak off?, if i did this, how much temp would I lose do you think?
how about kapton on top of the buildtak or straight onto the aluminum get damaged right?, sorry dumb questions but interesting?
also any good tutorials on applying kapton tape?
or make a new special clamp to hold it? I cannot tell from the vids how the wingnut works on the makersome upgrade, is there a screw it goes into?
Cheers again
Anthony

You know glass can be cut, right? Why not do that instead of finding a remedy for a problem that can be easily fixed...

Then go to your local glazier. While there get yourself a second sheet. Makes swapping out a quick affair.

I had same problem a while ago, never cut the glass so... what I did....
I purchased couple of cheapest picture frames from the local euro saver shop (couple of two packs for 1.49 each) plus cutting tool also for 1.49 , started cutting without any preparation/theory broke two of them, no luck! two days deep breathing...! Youtube ... "how to cut the glass" OK! feel ready now! let's start again, end of the tool to the oil (kitchen vegetable oil) make it wet and shiny .... and the pressure (pressure it the main point here if you push too strong on glass it will break but not the way you asking for) excellent! oil and the right pressure of my hand did the job just excellent ! Every time from now on! tried just for fun!
Experienced glass cutter :P

Keep in mind that if you use regular glass, instead of thermal glass, on a heated bed it will likely end up breaking on you do to thermal expansion.
0.5mm silicon thermal pad material (the kind they use on computer heatsinks) is an excellent way to keep a glass secure to your build plate. Just cut it into 5 1.5" squares (one for each corner and the one for the middle). It will keep the plate secure but it's easy to remove, and since there's no real adhesive it can be reused indefinitely.

As most glass plates are secured at corners or with a weak adhesive or tape on the corners - and as glass has a really low expansion coefficient anyway - it's pretty much never goiung to be an issue.
I used cheap poundshop picture frame glass with no problems for a while.
I much prefer my current aluminium bed. But as I pretty much just print on gluestick now - as long as the bed is flat the actual bed material is largely irrelevant.
