Touch Hole Question

[butterchurn]

I'm working on a smoothie that I aquired that needed some minor repair.  It has a stright 1/16th inch touch hole (no TH Liner) that is coned from the outside a la Danny Caywood.  I have to test shoot it, but do you think it would be advisable for me to open the hole up to 5/64 or just go and install a TH Liner?

Mr Caywood is a bit "touchy" about this subject. Why not jus' shoot it first n see how it does ... Danny does not believe you need a liner.
Bet yall find it do alright...

[Roaddog]

Yep if it ain't broke don't fix it.

as said , caywood doesn’t believe in liners . don’t even  get him started on the subject.
 While your vent isn’t coned from the inside , it still will work fine .
 When the touch hole does get to big then its time for a liner  but right now 1/16 should be fine . If you notice  the ignition is slow then you can drill her out

7f powder in the pan does wonders ... hard to find anymore.
Powder away from the touchole ... ya want the spark ta jump in Butterchurn...

If you decide to drill it larger, and # drillbits are accessible to you, there are 3  # drillbits between 1/16" and 5/64". IIRC the middle size is .70"

I agree with nessy.  Try the next size up in the numbered bits if that doesn't do what you want then move up one form size.  5/64" is a large hole, big enough to make it self priming if you you use 3Fg.

Thanks everyone!  I'll shoot it first and ask questions later!!!!!

I just put in a 5/64 for my brand new trade gun. Worked fine on Sat and went off everytime.

I happen to agree with Danny. I have done this for along time and one thing I have learned this sysyems works great! I absolutely dont have ignition problems.  They are dependable and fast. I know that there sre more people that believe a liner is a must. And I wouldnt try to change there opinion for any reason. The point That I am trying to make is both systems work. I would keep an open mind on both and try what you have first. If not satisfied then try something else. What you have should work fine if installed correct and I am sure that it is. I certainly hope that I have not affended anyone I sure didntmean to.

Sorry I didnt realize I had already sudmitted it before I proof read it.

[Captchee]

no problem ken , gotcha covered

[Sir Michael]

Ken, I agree as well. Although most of my guns have liners, at least one that doesn't and I have no burning desire to bore it out and install one. :lol:

[butterchurn]

I appreciate the info and discussion!

I would say to try it out as is before making any changes. That said....my harpers ferry rifle had a 1/16 hole in the liner. I found that it "plugged" way to easy...drilled it out to 5/64 and that was the end of that problem. There is a lot of talk or concern about "pressure" being lost by doing that. Well...I don't buy into that. On one end of the barrel you have this teenie little 1/16 or 5/64 inch hole...on the other end you have one that is almost .6 of an inch, now...which end or hole offers the least resistence to all that pressure? Just my two cents....
