What he ^^^ said, I'm next so I wait with great anticipation on what I hope is the best solution.
Race you. Mind you you've got a mate helping you and I've got a teenage daughter helping me!
Back on topic, I do like the sound of the multiple coats. Definitely don't want to touch powder coating.
One question. Apart from the media blasting and welding, how many of the steps can be carried out by oneself at home?
Thanks for the replies so far. I was expecting a long and in depth discussion about which method/s is/are best, and why. But it seems, for longevity, we have already found a tried and tested process fro the time being.
I was going to do research on marine applications and some motorsport firms (Paris Dakar) on their processes. May still do, but am liking the sound of the epoxy mastic. I assume its no where near as brittle as powder coat?

1. Media blast
2. Repair with new steel
3. Media blast again to key new steel
4. Immediately hot zinc spray
5. Pacify zinc with mordant solution (T-Wash or similar)
6. Acid etch prime
7. Two coats red oxide colour epoxy mastic
8. Final top coat in silver/grey epoxy mastic
A few questions COG.2. Repair with new steel
3. Media blast again to key new steel
4. Immediately hot zinc spray
5. Pacify zinc with mordant solution (T-Wash or similar)
6. Acid etch prime
7. Two coats red oxide colour epoxy mastic
8. Final top coat in silver/grey epoxy mastic
-I assume the hot zinc spray has to be done by a company?
-When you used the T-Wash, did you apply, leave and wash off, TWICE?
-Can you recommend an acid etch primer pls? Spray or brush on?
-With regards to the epoxy red oxide (PRIMER?) and top coats; did you brush the epoxy on, or spray it on (aerosol?)?
-Did you only put on one top coat?
Many thanks

Guys, can someone confirm if the 2k epoxy is the same as the 2k paint that is used for body work? If so, it seems possibly pretty dangerous for a home mechanic and should be left to the professionals.

No. It's not the same.http://www.locostbuilders.co.uk/viewthread.php?tid...
Could someone 'in the know' advise me on which one of these will suffice for Chim chassis welding please?

The Clarke is more expensive so I'd rather the Sealey. But will it be up to the job?
Thanks

Sorry Cad,
Don't be daft
I didn't take it as sarcastic Alun. It did dent my confidence a little for about 5 minutes

I think the trick is to get a top class welding machine and get used to using it
After some more research today, I'm thinking the same thing. Over £300 mark is more realistic: http://www.ebay.co.uk/itm/151070819775?_trksid=p20...Also a tube notcher from Frosts is going to be a good idea, as recommended by someone on PH.

This worked for tube joints,if link doesn't work just google metal geek templatates.
Thanks bat. Or maybe one of these: http://www.frost.co.uk/frost-pipe-tubing-notcher.h... Seen a demo of it on youtube and seems to work a treat.nuttyfruitbat said:
Hi cad tube notcher would be great but you'll probably never use it again,put the £75 towards next welder up and use the metal geeks templates they are spot on and free.
So pretty much buy one of these http://www.ebay.co.uk/itm/161441246029?_trksid=p20...And use that template software...
What would you use to cut it though? Not an angle grinder surely? Also, I don't have a drill press if its just an arbor on a drill..
Don't mean to sound negative, but I just want a simple solution, as the welding is going to be enough of a challenge
