Compressors selling out.

by Hajimoto

Hey guys and gals. Just a heads up that its Christmas season and the high pressure portable compressors are moving fast. I only have a few left and am waiting for the next shipment to arrive. The issue is that the demand was so high that the shipment has been delayed and I fear I will run out before December 14th which is when I was supposed to receive the additional skid.

What I would hate to see happen is that folks wanting to have their compressor for Christmas, may miss the opportunity afforded by in this inventory wave.

Accepting orders again

by Hajimoto

Because of COVID-19 I was forced to revamp and reconfigure my physical arrangement in order to comply with State required non-essential business operation. I worked around the clock to get all orders caught up and shipped before reopening to accept orders once again.

Any of you that have done business with Hajimoto Productions in the past know that we pride ourselves on processing and shipping orders very quickly but this pandemic has changed things and we ask that you be patient and know that your order is being processed and shipped but just at a reduced rate than what we typically execute.

For example, our Gauntlet order which normally takes 3-5 days to arrive took over 3 weeks to show up, so these types of things will obviously cause a ripple effect and delays which is completely out of my control.

Another variable that we have little control over is the supply chain of materials and components used to make some final products. A lot of the specialized CNC produced parts have had their production slowed because of this pandemic and as I start getting supplies in I will be reoffering the completed parts again.

Currently, there is no way for you the customer to know if a certain item is in stock or not until you try and add it to your cart. The only other way we can handle out of stock items is to hide all out of stock items. This method will cause more confusion as parts that the customer expects to find will be gone or the person browsing will not even know said part exists.

In closing, I would like to thank you all for your continued support as we all navigate through this pandemic. I wish you and your loved one good health and prosperity.

Thank you in advance for your continued patience and business.

2019/2020 Hajimoto Edition Gauntlet is retired.

by Hajimoto

A little while back I shared on social media and a few other outlets that the production cycle of the HE Gauntlet was complete. I never made an official announcement here on the Hajimoto Productions website though and this would be that post.

I would like to thank all of those that have supported this venture and I am proud knowing that all of you that have this limited edition has something very special.

I will of course be offering other limited edition in the future but I need to position the release in such a way that it does not misaglign with the next incoming wave of offerings by the manufacturers.

Thank you all again for your support,
Best Regards,
Hajimoto

The Gauntlet gets Flexible Power!!

by Hajimoto

Announcing a major performance enhancement for your Umarex Gauntlet. The Flex Reg will allow you to on the fly adjust your output pressure either up or down by 800 to 1000PSI! Hajimoto Productions have configured the regulator in two flavors.

  1. For the .177/.22 Caliber Gauntlets pressure range adjusts from 500PSI to 1500PSI.
  2. For the .25 Caliber Gauntlet pressure range adjusts from 1400PSI to 2400PSI
The new Hajimoto Configured Flex Reg installed on a 100% stock Gauntlet

As you can see there are no modifications required to the stock. Both gauges are clearly visible and allow the user to adjust on the go to suit their needs based on the projectile being used.

These are radar results from the installation and adjusted Flex Reg on the .22 Caliber Gauntlet. Can you imagine what those number will look like after the STK is installed!!

A stock .22 caliber Gauntlet with the regulator set to its factory 1100 PSI will fly JSB 18.13 grain pellets at about 786 FT/S. Once the Flex Reg is installed and cranked up to the maximum of 1500PSI, the same 100% stock Gauntlet delivers the 18.13 Grain pellet at a whopping 900 FT/S!!!

The Flex Reg is available alone or mounted on the extra capacity 22ci tank for the best of both worlds, more power and more shots!

Get your yours today!!

Gauntlet Transfer Port Talk

by Hajimoto

The purpose of porting, polishing, chamfering and bird mouthing air conveyance infrastructure is to reduce drag or pressure drop and inducing velocity stack. More efficient airflow to the projectile, in turn, increases projectile velocity.

Because velocity is increased, less hammer preload is required because the internals are delivering the air more efficiently which in turn, increases shot count.
The key and most important thing to remember is that the transfer port outlet inside the barrel should never exceed 80% of the bore diameter. This only because when loading a pellet into the breech anything larger than 80% tends to grab the projectile and gouge or deform it.

The projectile will try and load into the transfer port if the transfer port is too large.

The key is to taper and smooth like a funnel towards the chamber. Bird mouth the inlet side of the transfer port in the barrel so it is larger than the outlet side of the barrel again funneling the air rather than fighting a sharp 90° transfer of direction and creating jetties or vertices that essentially reduce the flow by upwards of 50% (See attached sketch).

Just like in engine building, anything you can do to help an aspirating system loose drag or pressure drop is an improvement in performance.

UMAREX GAUNTLET REGULATOR CHANGES

by Hajimoto
Notice how much longer the Chinese regulator is

I have noticed this for months but never really thought about writing an article about it until today. I have been sent several emails and have read in the forums about folks not needing to cut the forestock to install my HP Barrel Band. On previous Gauntlet models, it was required that the forestock be trimmed about 13mm or so to allow the band to fit on the tank without pressing against the forestock.

At some point in production, Umarex decided to use another regulator manufacturer other than Ninja. I noticed these non Ninja regulators on the, at the time new, .25 caliber Gauntlets.
I noticed then that they were about 13mm or so longer than the Ninja versions.

This new regulator being longer means there really is not a need to trim the forestock on the Gauntlet in order to fit the HP Barrel Band. As you can see in the photos, the non-Ninja regulator is much longer.

I have no idea how you would be able to determine if you will receive the Ninja version or the new one other than when you open the box and see for the first time.

So for any of you potential HP Barrel Band installers out there, if you have the newer regulator, your installation just became a whole lot simpler and most importantly to the average shooter, the warranty stays intact!

Lastly, even though these regulator styles are different, it has been my experience that they both accept the same shims. I have noticed the new version regulators are more sensitive to shim thickness than the Ninja regulators. IE; it seems to take less shim to achieve the same amount of increase. But the important thing is my shim kit will work in either.

Work and shoot safe!

GREEN LIGHT!

by Hajimoto

Hello my air gun friends!
Today I am announcing that the Hajimoto Productions moratorium has been lifted! I have worked very hard to get all the tunes, builds and custom orders out the door. I have also replenished all the parts and add-on that where wiped out from the hunting season rush.

As I have explained before and just to be clear, I do not entertain backorders. It has been my practice to open or close sales acceptance based on workload. If I have so much work that delivery times exceed my 15-day maximum turnaround time, I hit the pause button. My logic is, if I am having a hard time managing the current flow, why start a line of waiting customers that can wait upwards to weeks just to be in another line to get their orders processed. I operate by the first come, first served rule.

I would like to thank you all for your patience during these times of RED LIGHT.

SOLD OUT!

by Hajimoto

Hey guys! As you know over the past 1.5 months or so I have been hit hard by tuning requests and sales of tuned Gauntlets. As I posted a week or so ago, I place a moratorium on taking any additional orders until I got caught up. Well since that time, almost every mod I produce has been sold out.

So I apologize if almost every item you try to place in you rcart pops up as "SOLD OUT" but I am working diligently working to get those inventories back on line and open the gates once more.

I will be restocked and ready to receive orders for airguns, tunes and parts on Monday 10/12/2019. I will make another post to the news once I have things ready to go.

Thank you for your support and understanding,

2019 Hunting Season Rush

by Hajimoto

As most of you know I was hit with a substantial amount of Hajimoto Tunes and Gun Requests for the 2019 Hunting Season. Because I do not offer backorders, I adjust accepting additional orders so I do not exceed my self imposed maximum turn around time of 14 days. Typically my workload allows me to receive, build or tune a rifle and ship to the customer within 10 days or less.

I forecast that I will start accepting orders again within 7-10 days. That means somewhere around October 14th 2019 or so I will be accepting orders for tunes, builds and purchases of Hajimoto Tuned rifles. I will be posting this change here on the home page of the site so it will be easy to see the green light that I am receiving orders once again.

Please keep in mind that the Christmas season is fast approaching and this is typically another very busy time for me so we will be seeing this surge effect again soon. So if you are thinking of having services or purchases as a gift, act early.

Thank you for your continued support and understanding,

Hajimoto Productions.

Moratorium lifted!

by Hajimoto

I am caught up and appreciate your patience as I filled the huge wave of tunes and sales that splashed in. As I have done in the past, I will continue to execute this method in the future. Rather than take back orders and have folks in line for months, I will simply pause accepting any additional orders until I get caught up. That said, Starting today June 3, 2019.

I will be accepting rifles for tuning and orders for fully tuned Gauntlets. The Hajimoto Edition Gauntlet is now available as well!
