question about air hole below mortice
question about air hole below mortice
drilled a full bent today and the angle for the airway put the entry point a little lower below the mortice than is probably ideal. I've got about 1mm of clearance to the shank.
I am going to put an inlay/spacer/adornment (whatever you call it) in the stem and I wonder if I'm better off epoxy'ing the finishing slice of ebonite directly to the shank to cover that hole. maybe it doesn't matter?
I'm a little concerned that when i sand the shank to round it flush with the stem that I'll enter the end of the airway. That won't affect the smoke since the tenon enters the airway lower down, but it'll put a hole in the shank
any advice?

Re: question about air hole below mortice
Advice for the future: don't drill like that. Using a 5/16" mortise (and deep it looks) on an Oom Paul is just silly. 3/8" or wider, and a less deep mortise, and you can have the drilling angle you need without the theatrics.
Advice for now: cut a tiny briar dowel and glue it in there. Shape the pipe as needed, and sandblast if you expose the area.

Re: question about air hole below mortice
Oh, and as is, your mortise is weak like powderpuff, so filling that drill hole isn't merely optional imho. Fill it, cap it, don't do it again!

Re: question about air hole below mortice
If I use delrin tenons whats my other option?
and why is it weak if thats the standard delrin? Its .5" deep or so. Is the mortice the problem or the messed up airway drill?
sorry to be dense....

Re: question about air hole below mortice
oh wait, you're saying its weak because its going to break into the airway entry hole?
Re: question about air hole below mortice
Correct. You must fill that hole or the walls will break I guess.
Delrin or not - buy 3/8" stock for the next. I stock 1/4" to 1/2" delrin. Big mortises save lives!

Re: question about air hole below mortice
ah, only just found delrin in diameters other than the 5/16 I've been buying.
stupid.
thanks oh yee of large feet.

Re: question about air hole below mortice
Just to add and maybe clarify, I always try and make the draft and mortise intersect at a point where the draft always meets the base of my mortise
no matter what size mortise I use 5/16" or 3/8" on bent pipes that way I don't run into problems like yours. I know I haven't made many pipes and my knowledge is lacking to say the least but, I think most will agree with me on this...............well maybe most.

Try a larger airway, your pipes will smoke better!

Re: question about air hole below mortice
Sasquatch's advice is one option but consider that if you plug and cap the hole the owner won't be able to ream the airway. As it is, it isn't completely out of the realm of acceptability. I think your best option is to use a dremel or drill bit and remove the thin sliver of briar between your mortise and airway and continue with the adornment on the stem side. Sometimes this is your only option with certain designs. The better option is to drill your airway higher in the mortise then ramp it if your design allows it. Bent pipes (especially more severely bent ones) typically require some form of compromise ie. shortening the shank, ramping the airway, using a larger diameter mortise, shortening the mortise and tenon, or notching the mortise. Your best option will depend on your design.

Acutally because of how the airway terminates in pipes like this, I use a small airway than normal on these, 1/8" or 5/32" at biggest. Seeing a huge big oval where they holes meet is kind of ugly and I worry about tobacco jamming it up.

Okay, so my drawing skills aren't so good anymore nor have a machinist's accuracy but, it was just as an example.Sasquatch wrote:

I've been using a 9/64" and although the drawing shows the draft going into the bowl much deeper then it really does or should I can understand what you mean about a oval draft hole at the entrance to the chamber when using a larger bit.

Re: question about air hole below mortice
Interesting Sas, that you use a narrow airway in this pipe shape. I used 11/32 based on your other points about large airways being better. The lessons continue i guess.
Wayne, why go through the exercise of removing the sliver of briar? Is it just to avoid having it break later and leave an unfinished form there?
As an aside, I'm still nowhere near producing a sellable pipe so this will either be mine or something I give away to a buddy.

Re: question about air hole below mortice
All other issues/opinions aside, you need to take some length off the end of the shank so you have some room to work with on the bottom of the shank. As is, you'll either expose the draft hole or have a paper thin area.
I am more with Wayne on the acceptability of this type of drilling...no big deal. You have an exterior problem more than interior, IMO.

Re: question about air hole below mortice
Yes. By removing it you eliminate the unpredictability of the break. In someone else's hands it may break out a big chunk of the mortise, have a partial break that keeps the stem from fitting flush, it may break off and look bad, etc.calsbeek wrote:Wayne, why go through the exercise of removing the sliver of briar?

Re: question about air hole below mortice
Ok I think I'm going to try to combine the best of all of these ideas.
I took a slice off the shank which brought the air hole closer to the mortise. Now I plan to reface the shank and then re-drill the mortice with a larger bit (3/8" per Sas). This plan is:
a. excellent
b. a shit show waiting to happen
c. theoretically a good idea but you'll screw it up anyway

Re: question about air hole below mortice
I say D. It'll be a nice problem solving exercise and experience. I have learned a lot about making pipes by fixing (or trying to fix) the areas I screwed up, broke, etc.
