sandblasting my 8N

[mark logan]

I'm attempting my first tractor restore. I have my sandblasting scheduled and I'm doing the priming myself. My question is: Can I use my residential paint rig to spray the primer? We use this airless sprayer to spray primer on metal surfaces regularly. The 2nd part of this question is, Do I spray the engine block with primer? Thought there may be an issue with the engine temp.
Any help is appreciated

Can't comment on your sprayer vs your paint ( both unknown).. but if you've sprayed metal and it looks ok.. then you already know.

As for paint ont he engine.. I've never had paint burn off an engine except onthe hot portion of the manifold.. I have always just primed my engines when i did the tractor.. same with the paint.

i occasionally go back over the manifold with BBQ-Black hi temp paint.. .. if I am going for a show look or something..e tc..

I second what soundguy says.

If you have blasting scheduled but not done yet and it is with a commercial size blaster , then please DON'T ASSUME THEY HAVE IT MASKED SUFFICIENTLY TO KEEP SAND OUT OF CRUCIAL AREAS WHERE IT CAN RUIN YOUR TRACTOR!!! Go there and check it over 4 times before you give them the OK to blast. Make sure it is masked heavy enough that their high power blaster won't blow through it. If in fact it is a high power commercial blaster , don't let them do the sheet metal if they are using sand for media. They will warp it.A bad decision here will cause you a lot of grief and expense. You can't just hire any tank and truck blaster to do your tractor. Don't take it for granted that they know the difference or that they care. A moron can blast tanks and truck trailers and all too often that's who will also do your tractor. This is where sandblasting gets it's bad reputation for ruining things.Hopefully you have done your homework allready and you can disreguard this post.

next time youre around restored working tractor, just look at the manifold. The bottom where the carb attatches will have paint on it, while the rest will have been burned off.

That's the main reason I don't like sand blasting.. I see radiators ruined.. distribs filled with sand.. etc..

Soda blasting is ok.. but I now like electrolysis for removeable metal parts..

Thanks for the helpful info guys. I have since spoken to my sandblasting guy and has assured me it will turn out great. My tractor is stripped and prepped. Just doing rear axle seals etc.
Thanks, Mark
