Cheap Custon Gobos/Making a gobo

[stuartm]

Yeah I suppose, problem is being a school we have very little money to spend on productions :/.

Those are the prices for just the Lens tube you realise.

 

The actual price for the whole unit is about IIRC £600-£700

I did say IF I Remember correctly. In this case I didn't but now you have corrected me it doesn't matter.

Errm, you can buy brand new Selecon Pacifics with a 600W/800W lamp base from AJS for only £411 + VAT (£483 in total).

Where were they from?

;) one of our local regular suppliers,who I spend a lot of my budget with , and I didn't just buy 1.However even without a discount company's like 10 out of 10 will sell em to you complete for £375.05 (plus vat) for the 12-28 or 23-50 zooms.

[stuartm]

Thanks all I'll have a hunt around for them as they could be very useful for us.

Try this!

 

If you have some thin shim brass or steel then spray paint both sides of a piece about the right size then very carefully scratch through the paint for the logo design fully prepared and tagged then etch in ferric chloride. Given the money you could apply a photoresist and expose it to the logo image and etch. -Does really need very thin shim but you only need an M size piece!

 

I've done it, it worked. The results are entirely dependent on your skill with the scraping tool.

 

The only really good result is from a custom gobo made by a pro.

[stuartm]

That sounds clever - I was originally told just etching in tin foil would work but a) was too hard b) wasn't sure about how well they would stand up to the heat.

I did the CNC route at school before, it may even have been me posting before. Anyway I used a drinks can, with some plastic either side to keep it neat and held down. It worked fairly well, although we had to burn some of the coating/paint off the inside and outside by running it in the lantern outside for a while.

[stuartm]

A can was another thing we were looking out either a drinks can or the top of a baked beans tin.

 

These were by hand not by CNC though.

[Jivemaster]

Likewise you can use the foil from a take-away tray and learn a style of piercing either use a pin and make pinholes or use a cutter ot scalpel. -Cheap! the only cost is the lost blood while working with a scalpel!

[stuartm]

We did try using a CAMM1 machine to cut a card template and work with that but the problem was that because of the size some lines were like 1mm thick.

[timtheenchanteruk]

a custom metal gobo cant cost that much from Rosco surely?

 

I had a full colour glass one made up last year, it was less than £200, for glass!

Time was when you could buy a DIY gobo etch kit called the GoboMaker (link to second hand example), which I've never actually seen in real life, but I read about in a book. Seems to have vamnished off the planet, I've looked a few times over the years.

 

Any school should have PCB making abilities, so you could try coating a litho plate with resit, and doing a gobo like a PCB. Dunno if it'll work, but it should (or at least, might!)
