    Don't go for BLB bulbs; you need BL bulbs... They're better (higher output more yield) and usually cost less than BLB ones...

    Ask them about the spectral power distribution; if it's peaking around 360nm then it's fine.

    According the info at http://www.donsbulbs.com/cgi-bin/r/b...red~narva.html it's OK. But ask anyway to be sure.

    These are 25mm diameter lamps, so with 10 lamps spaced 2cm apart you'll have 43x60cm printing area. (Position the bulbs allowing at least 10 - 12cm space between the printing frame glass and the bulbs. If not, you may experience light banding / uneven lighting.)

    I don't know the product. But, as a general rule we don't use ready-made silver gelatin fixers (which mostly consist of ammonium thiosulfate); for Vandyke/Kallitype we use 2-5% "sodium thiosulfate". (I personally use and advocate "2mins in 2%" fixing procedure; that's adequately enough without compromising the print's longevity... But one has to pay attention to not exhaust the fixer by refreshing often.)

    Rapid fixers will bleach VDB, use plain hypo.

    You will have a very difficult time building a UV light source for an enlarger that will be intense enough for alternative process printing and it would be extremely expensive.

    Learn to use the sun to start with and save money to construct a UV printer later. The sun will give you immediate gratification or close to it.

    You didn't mention a contact printing frame. Do you have one? And yes you will have to produce enlarged negatives. Based on what you have written about expense of materials it sounds like to me your best option will be to go the paper negative route.

    Also plan on purchasing a step tablet. If you can't afford that then you can't afford to print alternative processes.
