PLEASE DONT MAKE FUN OF MY SPELLING AND GRAMMER ok i have a few components for a 1/2 bridge sstc here is what i have 4 IRFP244PBF (i guess full bridge is possible ferrite bead some 12.2v zenier diodes 555 pots caps 2 UCC37321P mosfet drivers 1 74ac04pc hex inverter 5v reg 12v reg 2 24v 10A transformers 1 18v 1A transformer resistors
i have an oscope clamp volte meter exc my secondary is a 30"X4.5" with 26g wire
CAN YOU HELP ME MAKE A SSTC OR DRSSTC WITH THESE PARTS
i got a $20 budget for extra parts (radioshack or newark if you can)

First couple things I see wrong: You will need a UCC37322 to go with your other UCC A ferrite bead may be too small for a GDT. IRFP244 is pretty small-15A may not be enough even for a small coil, certainly not enough for one with a secondary of the size you describe. Plus they are MOSFETS, which make a DRSSTC pretty impossible.

since he has 2 UCC37321's (which are inverting) he can connect the output of the first to the input of the second! (or use a seperate invertor beforehand eg the 7404, which is probably safer since will be unloaded at this point)

Firstly I dont know about your inverter but use the 74HC 14 variant (because its fast)

If you go this way, you can use one of the left over invertors in your 74HC14.

i dont think my mosfet drivers are inverting i found this witch uses the same drivers i would like to use these plans except i do not want a self res sstc because im going to be drawing arcs from it AND PLEASE STOP MAKING FUN OF MY SPELLING ITS MAKING ME VERY INSECURE i would also like to state that im 15 but have made spark gap coils for about a year and coilguns for about 4 years

What mosfets do you suggest (also the power needed to make a good sstc) as long as you keep the price below $100 for an h bridge or if necessary a 1/2 bridge
