Jig for Saddle Valve

[RRoberts]

I'm sure this has been done before, but here is what I did to aid my process.
3/8" hole thru 3/4" wood.
1/4" holes for the bolts.
Cut down on the distortion of the carto body too.
10 times easier now.
Hope this helps someone out.

What do you mean by distortion of the carto body?

When you punch a carto it can make the body out of round a bit.

NICE post thanks for sharing

its cool that you told what tools and holes ta do

After building 8 or 10 of these over the past year, the design has streamlined down to this:
Red oak for strength, and saddle valve both available at Lowes or HD.
Screws holding the valve to the wood jig, instead of through bolting.
Drill the hole then trim the wood to dimension is my 'easy' way.
You may mark ( on the block ) where the cart lands to get consistent hole placement.

You have to work out your own prescription for the hole.
...one or two, there is a definite pop, then how far past that is up to you.
For me w/ VG juice, two holes at 3/4 turn past pop. My wife's juice is 60% vg, running two holes stopping at the pop. Some may choose just one hole.
Hope this helps someone.

This is MUCH better than a saddle valve. http://www.e-cigarette-forum.com/forum/pay-forward-pif/272989-diy-carto-punch.html

If I were going to run the coupling hub version carto punch mentioned above, I would get these winged bolts and put a point on them. Wing Screw, Iron, Zinc, 1/4-20 x 1 In, Pk 25 - Thumb Screws - Screws - 5MNF5 : Grainger Industrial Supply
I like the saddle valve w/ wood for several reasons, The wood 'holds' the carto in place nicely, extreme control w two fingers. The main reason is I can go out and get these parts come home and make 4 in an hour.

The winged bolts look nice, but you'd need to be able to grind it to a sharp point on the end.

And as for speed, I use the shaft body one to punch about a hundred an hour.

Possible to contract out the point, or build a jig and do them on a grinder. Keep the heat to a minimum not to loose temper. Maybe add a carbide tip somehow. At least find a grade 8 wing bolt.
Speed! I don't think I have punched 100 carts in my life, much less an hour! My parts can be had local, I don't have to wait on a mailman.

Sorry, I'm not knocking your set up. I think it's pretty cool really. Just not a fan of the saddle punch in general.

It's all good brother, I just hope we helped someone in the process. ECF was there for me, thank goodness. PIF
