Rhino Lining my tub, need to clean every bolt hole out, which metric taps to get?

[alex e]

M8 X 1.25, M6X, etc......but having never purchased a tap in my life what am I looking for, brand, etc? Is there a certain kind I want to get. Most of the bolt holes are rust filled and I wanna clean them suckers out so I can install all my beautiful new bolts after the RL is in.

Tool guys chime in here. What did you use and which sizes do I need? Thanks in advance!

After you run the tap through the boltholes, install sacrificial, long bolts into those holes to protect the threads. If you don’t, you will be trying to clean that crap out of the threads later.



Any decent quality tap will work fine.


6x1.0
8x1.25

when I did mine, I put little corks or rolled up tape in all the holes...even running taps thru that guck is a PITA....if you have corrosion issues, I'd prep your surface, then run the taps thru each hole, then vacuum out the holes (if blind) before you use the corks or atpe...and then off you go, pull the tape as the guck stiffens up, but before it cures....

There are 2 other sizes beyond the m6 & 8.... and I'm not positive what they are, but they're for the roll bar mounts. I think they're m10 & 11 and different threads. Sorry I can't remember, but you should be able to take the bolts with you and use the gauge at the tool store to get the right tap. Or, buy a gauge first and measure them at home.

Thanks for the tip

I purchased sacrifical bolts at Fastenal, and swiped a mess o' golf tees plus some of those squishy vinyl plugs from all my powdercoating jobs....should work nicely.

I didn't prep in any way when I had the tub sprayed. I put the taps into a cordless drill and spent about 20 minutes chasing the line-x out.

I havent lined my tub yet, but have used this Craftsman kit many times and seems to work well for the money, $50.

I just don't see the future need for more than the few taps this job requires. I
have been eyeing a Matco set but $100+ into the cruiser goes further for parts
than tools....

I'm big on buying tools, but can see the logic in your thinking. Three taps will do 98% of what you need. After it's all done, you can toss them into your tool box for safe keeping.

Edit: better yet, borrow them from a friend.

A few years ago I bought a set of metric taps (taps only, no dies) at Sears that has all the sizes you need for virtually everything on a Cruiser. A nice sturdy handle, small plastic case, Craftsman brand, for something like $20. One of my best purchases.

sets versus pieces?

that is the time honored question. I buy sets because the individual parts cost less per item when the price is spread over a whole set of items. one tap/die might cost $10, where as the whole set might cost $60.

this is of course, no excuss to just throw money around. i eventually find other applications for some of the other pieces and then the savings is worth the effort.

this scheme did not help me when i rebuilding my last engine. i busted the tap for the head bolt hole on top of the block, and not only did i have to get the busted end out, but the individual tap was abotuu $29. so, some day i break even, and most days i win.

i like an organized tool box, and so having the set in a box of pieces helps that happen automatically.

i do buy individual parts. when i needed the socket to turn the crank bolt off/on/engine over, i bought just the one that fit, and not the whole $250 set of 7 sockets it was in, so i do have limits myself.

either way, have fun, stay focused, and keep them running. eventually some movie maker will offer thousands more than their worth just to blow one of em up in some movie set. all the $$$$ will come back home to rosot in our pockets. and we can use it to buy tools galour, and fj's more.

chasers

If you havent done it already the bolts are a good idea

if you have to clean it out or just clean out rust have a look at Thread Chasers ---just google it

Grab a bunch of nails with different size heads. Pick a nail head that is a little bit smaller than the bolt hole diameter, put it just below the top of the hole, hit it with a light coat from a hot glue gun. When you are done with the lining or painting, just go back and pull out the nails and the glue will/should come out with them. You may need to clean up one or 2 but that is really easy considering that the hot glue really sucks at bonding to metal.

Come to think of it you could probably even use candles that come to a tapered tip... hit them with a torch quickly and jam them in the hole. Any wax in the threads left after you pull them out could be very easily and quickly blown out with compressed air.
