Shortening The Length Of A Lapdist Cylinder

I am hoping that someone here might be able
to help me with a problem that I can’t seem
to find a solution to.

Late last year I bought a new cylinder from
Lapdist. I have bought other products from
them in the past and have found that all their
products to be of extreme high quality. I have
never hesitated to recommend them highly to
my friends or members of TP.
And, I will continue to recommend them in the
future.

My problem:
I would like to shorten one of my cylinders about
1/4” (about the thickness of the flange at the base
of the cylinder.
However, I am afraid to try to do it myself since,
the plastic/glass might shatter. I thought it might be
cheaper to shorten the present cylinder instead of
ordering another one.
They are not cheap!!!

I have sent a number of emails to Lapdist inquiring
about the cost to cut off the end, but so far have
not received a reply.

I visited a plastics company here in the city, thinking
they might have the tools to do the job, but they did
not. I thought of using a hack saw, but don’t have the
facilities to hold it while I cut it….and then I am not
sure if it would cut through and it would be ruined.

Do any of you have a suggestion as to how I can do
this? I would appreciate any suggestions…

Thanks

Panos!

Good to hear from you.

Why do you want to shorten the cylinder? Is it just to get rid of the flange? Maybe there’s an alternative to taking a saw to your cylinder.

Panos.

It would be very difficult to cut the end “squarely” ie without going away from a straight line all around the cylinder. You would need a jig to hold the tube and as you realize this could damage the tube. Lapdisc are unlikely to reply to you as whatever they might suggest (and even that is highly unlikely) would probably damage the tube.

With a distorted base you would not get a vacuum.

The only thing I can think of which would do (this highly unrecommended job ) might be to use a pipe cutter. The type that you tighten and then rotate it round the tube. But with a flange at the bottom (it might not be possible) and with the large diameter, it would cost more than a tube to buy

You could perhaps try a plumbing hire company to see what they have. But I think it unlikely thay have anything.

Please tell us why you want to shorten it. (I have visions of you trying to fit it on in the shower cubicle and it’s not wide enough there! :)

As another thought, If you just want to get rid of the flange, You could try “Burnishing” it off by holdinng a drill with a burnishing disc in a vice (vize) and then holding the tube and rotating it around the revolving disc. - Or as a last resort a file. Wear Goggles!!!

And make sure there are no sharp edges.!

I do not know exactly what the makeup is in a Lapdist tube but I have cut various materials in my chop saw. I am assuming that the flange would keep you from placing the tube on the saw fence squarely. If so then just place tube on a 2x4 so the flange overhangs it. As you are slowly feeding the blade down onto the tube slowly roll the tube away from you. I have done this on wooden reel seats, pvc and aluminum and have made nice square cuts. Another way I could think of is to chuck it on a lathe. Use hi speed with a slow feed and make sure there is no runout on the tube. A good way to determine if it is going to chip out or not is test it right on the edge of the flange,maybe a 1/32 in from the edge. If you are going to use a hacksaw then I would take some time making a custom vice for your tube. You would need a holesaw, scrap 2x and clamps. Good luck!

As long as it isn’t hitting the top, your cock doesn’t know if it is in a 8” cylinder or a 12” cylinder. From a performance standpoint, there is no difference. I can’t imagine why you want to shorten it.

Thanks to you all for your replies.

Well, the problem that I have is with my new Mushroom
Head Maker which is composed of two cylinders….the
bottom regular cylinder and the top larger cylinder.

I told in my thread about the heightened sensitivity after
using the MHM for a while…and how much I liked it. You
probably viewed that one. The sensitivity is mind blowing,
to say the least, and is really quite enjoyable!!!

Howeve, I began to worry about this new sensitivity since
it had become so very intense, and finally decided to go to
the doctor to check if I had somehow damaged it and also
just to be on the safe side. I also noticed that it was more
sensitive on the left side of the glans than the right.

I have always known that when erect that my glans was
larger, or actually longer, on the left side than on the right,
a lopsided head…LOL. I was told by Lapdist to make sure
that I measured correctly before ordering, and I had thought
that I had done just that. But, this lopsided bit has been such
a part of my life that when I measured for the MHM I forgot
and only measured on the right side of my penis from the base
to just under the glans…and I did it BP which wasn’t a good
idea.

So, I’m about 1/4” short of being able to have the glans/head
enter fully into the larger, top cylinder…which is the point
of the MHM. The right side of my glans is fully inside, but the
left side is “just” barely inside the top cylinder. When pumped,
the glans ridge on the left side swells partly in and partly back
into the main, lower cylinder.

In order to get the glans fully in…both sides…I have to pump
at a higher Hg…over 10, and that is reason my doctor says has caused this heightened sensitivity…the glans being over pumped,
which has caused a stain on the left side of the glans!

I believe that if the bottom flange of the main, lower cylinder
was removed, it would give me the extra space I need to get
the glans fully inside and then I could pump at a lower 5 to 7 Hg.

I do not have the equipment…ie a vice, saws, etc. A vice
would be difficult to hold the 2 part MHM, anyway and I know I
couldn’t hold it and saw at the same time. Since I live in an apartment I do not have a basement or garage workshop, etc.,
and if I did I would probably be poor at it.

I agree that it would be difficult to cut it straight, as one of you mentioned, which would possible cause a bad vacuum seal.
I realy don’t see a need for a flange at the base, anyway.

I sent another message to Lapdist today, with hopes that I
might get an answer. I really can’t afford a new MHM at this
point, since they are very expensive. But, maybe I could
afford to have the one I have cut off.

I hope this explains my problem.

Thanks again for your input and for any other suggestions that
you might have.

Now I understand your problem. Before you cut it though, try this next time you pump. Start with an erection if you can and once you enter the cylinder, bone press it into your groin and then pump up. Once you get up to your regular pressure, continue this negative type milking by regularly pressing inward on the cylinder. Since you are only looking for 1/4”, this might be enough to give you clearance.

If you do end up having to cut it, it really shouldn’t be very hard. I would recommend a fine tooth saw like a hack saw and just use the flat surface of the flange as your cutting guide for the blade. If you just use light pressure and take your time you can probably just hold the cylinder down with one hand over the edge of a tabletop and put a towel underneath the barrel of the cylinder to help keep it from slipping around on the tabletop. Once the flange is cut off, you will need some sandpaper to smooth the cut edge.

More thoughts on the subject. Perhaps the best type of saw would be a “Junior” hand saw. These are fairly small saws for light work with something like a six inch blade. You should be able to saw using the flange as a guide, which should keep the saw line fairly straight. Then you need some fine sandpaper to finish off, by laying the sandpaper on the table. Holding the tube virtical on that and slowly rubbing the tube over the sandpaper to smooth things off and correct any irreglar bits. (Not forgetting to round the edges) There are various type of ‘junior’ saw so a google search on small saws will probably give you a few pointers as to the one which suits you best.

Take your time and with care you should be able to get a good seal.

But do as Gprent suggests first, and you might try raising the base of the tube upwards along your stomach and then pumping. I find for some reason that gives extra girth so it’s possible it may help the “lesser” side of your glans to slip in the required way.

If you’re not quite sure what I’m talking about there, I’ll go into further detail.

There really can be no subject under the sun which doesn’t get an airing here :)

Before I answer gprent and petitfaun….let me say

HIP HIP HURRAY !!!

There just had to be a glitch when I sent my emails to Lapdist before (probably my computer again!!!), because when I sent
a message to Lapdist today, I got an immediate answer and I’ve been told to send the MHM back to them and they will shorten it for me….for a very reasonable price.

They really do have great Customer Service!!!

Don’t hesitate ordering from Lapdist, or even asking questions
about their products…

:up: for Lapdist!

Let us know how long it takes them and how satisfied you are with the results after you get it back.

I’ve just returned from having a very nice dinner here in NYC
with two of the TP Moderators.
It was my first time meeting peforeal and found him to be an extremely nice and extremely nice person, with a big, friendly smile on his face most of the time.
The other person was my neighborhood friend, mafero. He
set up the meeting, and is always a pleasure to be with.

I’m full of good food and my soul is satisfied because of the
good fellowship that we enjoyed together this evening. I will
look forward to a repeat soon.

Then, after that enjoyable evening, I returned home to find an
email message from Lapdist, requesting that I return my MHM to be shortened.

Could I have had a more perfect day?

Now to answer you email…
Most of the time I do enter the cylinder with an erection, and
most of the time pushed the cylinder into the pubic bone, and then did the pumping. This was the only way that I could get
as far inside the larger cylinder as I did. But, to get it fully in (well almost fully in) I had to pump up to 10Hg. This is probably how I damaged, or caused the left side of my glans to be over pumped and creating a glans that was extremely sensitive.

I can’t say that this extreme sensitivity was not enjoyed….to
the contrary…but, I did realize that it probably was not normal and stopped. It was confirmed after visiting my doctor.

So, now I don’t have to worry about it and will be sending my
MHM back to Lapdist for them to shorten it for me. I just hope that after it is shortened that the heightened sensitivity stays with me….so far it has and I have not pumped with the MHM for about 2 months now.

So. it has all ended well!!!

petitfaun

Thanks for the suggestions, but all is well now and I will be sending
the MHM back to Lapdist tomorrow.

Lampwick

Will do, buddy. And, Thank you for all the help you have given
me over time. It was and is much appreciated.

Glad to know it’s all worked out OK Panos.

Well, from the time I sent the Lapdist MHM back to LAP Distributing LLC to be re-sized, it took about 10 business days.

As always, EXCELLENT SERVICE. There should be no reason for anyone to doubt the quality of Lapdist merchandise, or worry about their customer service.

Actually I had only thought that the base cylinder “flange” would
be removed, thereby shorting the base cylinder length, but somehow they re-sized the base cylinder and it
still includes the “flange.” That is very nice and a pleasant surprise.

Thank you Lapdist…
